Rolleiflex 4x4 - the 'Grey Baby' Rolleiflex

Rolleiflex 4x4
From the Rolleiflex 6x6, which from the beginning set the pattern for the development of the twin-lens reflex camera, the Rolleiflex 4x4 has taken the basic principles of its construction.
Rolleiflex 4x4 manual
On top of being given old cameras, with something of a reputation for them, occasionally I am lent them: one such borrowed camera I have been testing recently is the Rolleiflex 4x4, a 127 rollfilm format twin-lens reflex camera from the 1950s. The camera still has its original dual-lens cap and strap, missing its clam-shell ever-ready case, and has clearly been well used, the grey leather panels wearing down to its natural colour. Inside the camera back is a dealer decal reading 'Foto-Krischker Tirschenreuth', Tirschenreuth being a small town in Bavaria close to the Czech border.

The Rollei Club website has a detailed page on the evolution of the Rolleiflex 4x4. The initial version of the camera was introduced in 1931, combining the innovations of the larger original Rolleiflex with the increasing popularity of smaller format cameras such as the Leica, amongst others, and developed through the 1930s to the early 1940s - and then brought back in 1957 with the distinctive grey leather inset panels and painted metal trim. The 'Grey Baby' or 'Baby Grey' Rolleiflex inspired a number of Japanese-made 127-format twin-lens cameras such as the Yashica 44, Primo Jr, and the Waltz Automat 44, often in grey. The grey version of the Rolleiflex 4x4 had a much larger production run than any previous model, over 60,000; it was superseded by a final black version with the same specifications from 1963, in much smaller numbers - less than 5,000, and finally discontinued in 1968. All versions of the camera were simply called Rolleiflex 4x4 by Franke & Heidecke/Rollei, but with codes for internal use: the final camera, whether grey or black, is the K5 model. However, the Rolleiflex 4x4 is colloquially and commonly known as the 'Baby' Rolleiflex, although never officially named as such; by contrast Zeiss Ikon adopted the 'Baby' prefix for their 127 cameras based on larger original versions, such as the Baby Box Tengor. Perhaps, unlike Zeiss Ikon - catering for all pockets - aiming at a wealthier customer Rollei disdained the colloquialism of the word 'Baby'.

Rolleiflex 4x4
The Rolleiflex 4x4 cameras are as well designed and constructed as the larger 120 cameras, and with similar specifications. Pre-war Rolleiflex 4x4s all had Tessar lenses; the post-war model features a Schneider-Kreuznach Xenar f3.5 lens with a focal length of 60mm (the serial number of this particular camera's lens dates it to 1958, fairly early in production); the viewing lens is a faster Rollei Heidosmat f2.8. The lens will focus down to 1 metre, and the focus knob has a depth of field scale around it and includes a film speed reminder for ASA and DIN. The shutter is a Synchro-Compur with speeds from 1-500, plus B. There is flash sync with a PC socket and a switch for electronic flash or flash bulbs which also has 'V' for the self timer. There is a small button underneath the shutter surround to change this switch. The threaded shutter release is angled upwards and slightly out from the body under the taking lens.

One feature of the Grey Baby Rolleflex 4x4 which firmly locates it as a 1950s-designed camera is its coupled LV (Light Value) system. Aperture and shutter speeds are linked together, so a number of combinations of the two can be selected which will give the same effective exposure. Many cameras during the 1950s and 60s used such systems before this fell out of favour; most contemporary commentators online seem to conceive of the LV shutter-aperture linkage as a solution to a problem that barely exists. On one side of the taking lens the LV numbers run from 2 to 18 with a dot to indicate the selected number; the other side of the shutter has the aperture and shutter speed settings.

Rolleiflex 4x4 aperture and shutter speed selectors
The aperture ring has a raised section with a grip which needs to be depressed to turn this separately from the shutter speed section in front: on the other side of the shutter this moves the red dot in relation to the LV numbers to select the exposure; it is possible to select intermediate aperture stops.
The back of the camera has a detailed exposure guide, essentially a sophisticated version of the 'sunny 16' rule, with subjects and lighting conditions, which, when correlated with film speed and adjusted for time of day, produce a number to set on the LV scale of the shutter.

Rolleiflex 4x4 exposure guide
One final observation about the LV scale worth noting is that the shutter has a series of numbers picked out in green beyond the 'B' setting, representing whole seconds for calculating long exposures (as the shutter has 1 second as its lowest speed, the 'B' setting actually represents 2 seconds on the LV scale).

Rolleiflex 4x4 viewfinder
Opening the lens hood reveals the ground glass screen viewfinder with a subtle grid to aid composition; pushing on the front of the viewfinder hood flips up a magnifier to aid focus; pushing the front through until it locks down converts this into the sports finder. The magnifier can be slipped out to replace this with corrective lenses to compensate for eyesight; pushing in the hinges on either side of the hood collapses the whole. The viewfinder has parallax compensation, though on examining the camera it isn't obvious how this is achieved, but possibly through a subtle movement of the focus screen, not dissimilar to the parallax compensation with the Rollei 16.

Opening the camera, the base around the tripod mount has a rotating lever, turning anti-clockwise, to push forward the hinged latch which, when flipped, allows the whole bottom and back to be lifted upwards opening the camera to load the film. Film travels from bottom to top in the camera, both spool holders flip out in different ways to enable loading and unloading. The frame counter is entirely automatic, without a red window. Once loaded and closed, the film is advanced until the numeral 1 appears in the counter window and the advance knob stops until the shutter is released; the shutter release is locked when the viewfinder hood is down. Without a film in the camera, the counter shows '0' and the shutter can be cocked by turning the advance knob and released as normal. The pre-war Rolleiflex 4x4 cameras had an advance lever, but the post-war version has a knob instead (many of the Japanese 4x4 TLR cameras did have advance levers however), more like the contemporary  Rolleicord cameras, yet the 4x4 retains the Rolleiflex name.

Rolleiflex 4x4 - back open
With the back open, two small levers to the right of the film window can be seen. One appears to be a feeler for the film; the second appears to be a lever that, when released by opening the back, resets the film counter. When first testing the camera, the shutter seemed to stick at all speeds; after thinking that this was simply the fact that, after sixty years, the shutter needed to be stripped down and cleaned, I moved the flash sync switch to the bulb position - and the shutter works as accurately as one might expect, even at slow speeds. Evidently the electronic flash sync seems to conflict with the shutter mechanism and as this hasn't turned up in searching for shutter problems, so this might just be an idiosyncratic issue with this particular camera.

Rolleiflex 4x4 with Ilford HP5 Plus
With the first roll of film through the camera (a short off-cut of cut-down Ilford HP5 Plus), the qualities of the Rolleiflex 4x4 are immediately apparent. The 127 rollfilm format - in all its standard frame sizes, 6x4, 4x4, and 3x4 - provides larger images than the standard 35mm frame; set against this is the fact that many, if not most, cameras designed around the 127 format tend towards the cheaper end of the consumer market, inevitably not fully taking advantage of the larger negative area. In the image above (which could of course be shot on finer-grained film than HP5 Plus) the sharpness of the Xenar lens is clear despite the nondescript subject matter. The camera sits well in the hand, perhaps easier to operate than larger 120 format camera, supported by the right hand, focus by the left, the shutter release positioned to be operated by the right thumb, and switching support from one hand to other to advance the film simple enough.

Rolleiflex 4x4 with 35mm Ilford Pan 100
As well as medium format film cut down to 127, I also ran a roll of 35mm Ilford Pan 100 through the camera and found that all the frames were out of focus in the centre; the image above was one of the more in-focus frames. Having used 35mm rolled with 127 backing paper previously, I was surprised to find this happen with the Rolleiflex, although I have had similar issues when using 120 film with 116 backing paper, as the smaller width of the film is not supported at the sides with the result that film flatness suffers. However, the 116 frame is nearly three times longer than the nominal 4x4 size with the Rollieflex 4x4. Other 127 cameras seem to be better at this, with the V. P. Twin possibly being the exception, but not consistent. When using the camera with cut-down medium format film and 127 backing paper, the main problem that cropped up was that the first frame did not align correctly with the start of the film, resulting in half an image with the tape visible; this may be down to the film not being taped to exactly the right position on the backing paper.

The Rolleiflex 4x4 is clearly one of the most sophisticated 127 format cameras ever made; some of the Japanese 4x4 TLR cameras do have light meters, the only feature that could be thought of as lacking from the Rolleiflex. This last iteration of the Rolleiflex 4x4, coming at the time that cameras began to feature built-in light meters, was perhaps popular enough at the height of the late 1950s 4x4 twin-lens reflex craze for there to be little impetus to develop the camera any further. As with other Rollei cameras, there is an attention to detail in the construction and manufacture that occasionally feels like over-engineering, but solid enough to inspire confidence and small enough for portability, perhaps able, briefly, to compete with the sophisticated 35mm cameras of their time. As a result, the Rolleiflex 4x4 is still an eminently usable 127 camera, continued access to 127 film notwithstanding.

Zeiss Ikon Ikoflex Ic

Zeiss Ikon Ikoflex Ic
The twin-lens reflex has been eclipsed by the popularity of single-lens reflex cameras. Excellent results are possible with some models of this design, however, and they often represent the least expensive way for a photographer to begin working in medium format.
Ansel Adams, The Camera, 1980
Twin lens focus cameras were around for many years before Franke & Heideke introduced the Rolleiflex, but, like the Leica with 35mm film, it became the archetype - and inspiration - for the many twin lens reflex cameras that followed, as well as establishing the 6x6cm square negative format. TLR cameras were produced by many different manufacturers for decades, the majority were made between the 1930s and 1950s, but the twin-lens reflex design fell out of favour from the early 1960s (notable exceptions such as the Mamiya C series and the Rolleiflex itself, as more fully-featured, prestige cameras, were made until the 1990s and 2010s respectively).

I bought my original Zeiss Ikon Ikoflex Ic in March 1996. It was my entry into medium format as a student, being significantly cheaper than a Rolleiflex or MPP's contemporary Microcord/Microflex cameras, and a fraction of the price of medium format SLR cameras at the time. It cost £99 as a commission sale from a camera shop which meant there was no secondhand guarantee. A tutor at college described it as being "two-and-a-quarter-inch", and, although at that point I knew of medium format, I'd not heard it described as such before.

The above image is from the first roll of black and white film I shot with the camera. It's one of several shots made standing the Ikoflex on the floor for long exposures, easy to do with the typical twin-lens reflex waist level finder. The Ikoflex Ic I'd bought had a 75mm Novar lens, a cheaper triplet lens made by other manufacturers under license for Zeiss Ikon; it was also available with a f3.5 Tessar, but at the time I wouldn't have known to distinguish between a Novar and a Tessar. (Edit 30/11/18: looking through my images with this first Ikoflex - and images of the camera itself - I'm now sure that this was with the Tessar lens - although, again, I wouldn't have known the reputation of the lens at the time).

The immediate difference in image quality with the shift from 35mm to medium format (even with a cheaper lens), and also the changing relationship of depth of field with longer lenses on the format, was clear from the first few prints I made from the negatives from the camera. The photograph above shot in May 1996 after I'd had the camera for a couple of months embodied these qualities almost perfectly - almost, as there appears to be a small amount of either a fall off in definition from the lens to the corners, or possibly a little camera shake in a twisting motion, nonetheless the quality of images like that above suddenly looked more professional. Another student at college had a Lubitel 166B, and it was very clear that the images, with vignetting and light leaks, were poorer quality in comparison to the Ikoflex.

The Ikoflex also served as my introduction to night photography, using the camera on 'B' with a tripod. To calculate exposure times, I set my Praktica SLR to the same aperture and counted how many seconds between the shutter opening and closing, without factoring in reciprocity loss. This method worked well enough with regard to the Ikoflex's selenium meter being unusable at night. While at college I mostly shot Ilford HP5 Plus in the Ikoflex. On my contact sheets from the time I didn't write down developing details (curiously, I did so for most contemporary 35mm contact sheets). The developer at college would have been ID11, and usually used 1+1. Although I didn't write down any information about the developing, I also didn't push process any of the medium format at the time, which I had begun doing in 35mm. Later, once outside college and not having access to a darkroom, I shot a wider variety of films which I had professionally processed, mostly at Jessops. One film that I did use was Delta 3200 (the film itself hadn't been introduced until after I left college) for some handheld night shots, possibly shot on 1/10th. I used the Ikoflex much less when I bought my first Canon A-1: I last used it frequently in 2000, and it was stolen in 2003. Unlike the Canon A-1 or Olympus Pen EE3, I didn't feel the need to replace the camera as soon as I could, (or even, much later, the Brownie). However, a few weeks ago I saw an Ikoflex Ic in an online auction for half the price I paid for it twenty years ago, and bidding it up by a few pounds to nearer two-thirds that price, I won the camera. Ideally, I should have probably waited for a version with a Tessar, or the last Ikoflex model, the Favorit, but in replacing the Ikoflex Ic two decades on from first buying it provided a sense of resolution.

The Ikoflex Ic was the penultimate model in Zeiss Ikon's TLR series. It has a typical frame size of 6x6cm on 120 medium format film, with a 75mm Novar or Tessar f3.5 lens, stopping down to f16. The viewing lens is a 75mm f3.5 Teronar. The Prontor SVS shutter has a full range of speeds from 1-300, plus B, and a switch marked VXM for self timer (V), electronic flash (X), and flash bulbs (M). The self timer on my camera doesn't work, and in my experience rarely works on Prontor shutters from fifty to sixty years ago. The shutter can appear stuck if the switch is inadvertently knocked on V, easy to do, but switching to X releases the shutter (I have wasted a few frames with my new camera this way). Both lenses are provided with screw threads, but in different diameters. The taking lens has a 35.5mm thread; externally, it will take 37mm push-on filters or hoods. Two windows around the taking lens display aperture and shutter speeds; the aperture settings have a red dot for a hyperfocal distance between f8 and f11.

The focus knob is on the left hand side of the camera when holding it. On my camera it's marked in feet denoting an export model. Close focus runs down to 3.6 feet, with depth of field markings, and a hyperfocal dot on the scale between 48 and 15 feet to correspond with the dot on the aperture scale. On the right hand of the camera is the shutter release - lower on the body than older Ikoflex models - and the cable release socket in the top corner position where the older cameras had the shutter release. The release pivots outwards for shooting, with the shutter locked when it is pushed in. This shutter release is key to the ergonomics of the Ikoflex: the weight of the camera is taken in the right hand while focusing with the left hand, but the thumb of the right hand operates the shutter and also helps steady the camera between both hands. I haven't used older Ikoflex cameras, but I can imagine having a shutter release on the top of the camera makes it less easy to use handheld. The right hand side of the camera also has the frame advance knob, with a film reminder with "PAN/IR/ORTHO COLOR NEG/POS" inscribed on it, the COLOR section doubled, presumably for tungsten or daylight film and the frame counter, with its reset dial, and a PC socket for flash.

The waist level viewfinder hood is nicely sprung to pop open when the catch is released on the body. Rather than just plain ground glass, the viewing screen is actually a fresnel lens (fine concentric lines can just be made out). There's a flip up magnifier lens for fine focusing, and the cover of the viewing hood with the nameplate itself flips up to create an eye-level sports finder. The viewing screen has ruled horizontal and vertical lines to aid composition, and also displays the lightmeter needle. The Ikoflex Ic's built in lightmeter was one of the reasons for buying it (not heard of the 'sunny 16' rule at the time). The cover on the front of the camera flips up, and the needle in the viewfinder has EV markings from 2-16; on the focusing knob there is a calculator on focus knob with ASA settings from 5-320, including -2 -4 adjustments for filter factors, where the EV numbers can be read off against shutter speed and aperture combinations. Exposure times are listed up to 60 seconds; whole seconds are marked in green, and can be seen appearing at the far end of the calculator in fast film settings with a high EV, which the manual warns about. The selenium meters on both cameras I've had worked perfectly well with black and white and colour negative film; there are some references online referring to the Ikoflex Ic having a CDS meter, but I've found nothing conclusive, perhaps some cameras were customised with CDS cells replacing the selenium meter.

The Ikoflex Ic has an automatic frame counter with double exposure prevention. This was initially confusing, and, with no manual available when I bought my first camera, had to be worked out by trial and error. The man in the shop when I bought the camera loaded it for me, and the frame counter reset fooled him initially: he got this to return to 1 after having wound a whole film through the camera. I found the very first film from the camera had only part of one frame exposed. The correct way to load the camera is to ensure the frame counter has passed '12', which will then freely rotate (this may have to be done manually). On loading the camera, the film is advance to the first frame using the red window on the bottom plate, then the frame counter is reset to '1'. Once the shutter has been fired, there is an interlock which prevents the shutter firing again before the film is advanced (it's possible to cock the shutter without advancing the film, but it will not fire).

When I first used the Ikoflex twenty years ago, the square format was a novelty and provoked more care taken over composition. This is partly helped by the lateral reversal of the image in the viewing screen, which does need some experience to become familiar. Although typically twin lens reflex images were often cropped when used professionally, composing to a full, square format is more challenging; picking up the camera again after many years brought this back with a distant sense memory of how it felt to use. It has also been an excuse to sort through old negatives, many of which I had never previously printed or scanned. Except for Kodak Portra 160, I didn't use any film slower than 400 ISO with my first Ikoflex camera - which was the case generally, in 35mm as well as medium format. Twenty years after first using the Ikoflex Ic, I recently shot some slower, finer grained films with the new camera: Agfa Superpan 200, Ilford FP4 Plus (rated 200), Rollei RPX 25 and a roll of Kodak Plus-X with a develop before date of 03/2006, which I happened to finish on Expired Film Day 2016.
