Coronet 6-6

Coronet 6-6 camera
The start of the new #shittycamerachallenge's 'holiday apocalypse' last month, running from November to January, almost neatly coincided with the new coronavirus lockdown restrictions coming into force in England on November 2nd. As with the previous period of 'lockdown' from March this year, the restrictions have not been as stringent as in many continental European countries: working in education, moving from the only then recently introduced tiered system to the lockdown had essentially no difference to my daily life, as I was still physically going to work, face-to-face, in the same way I had been since the start of September, while watching the rolling seven-day figures of cases, hospital admissions, and deaths, rise with what felt like inevitability, once schools and colleges opened at the start of term, and stayed open throughout. I was taking my photographs for the #shittycamerachallenge on my way to work, at lunchbreaks, and, on a couple of occasions, during exercise, alone, which was permitted. Despite taking all the precautions that were practical at work, again, with what felt like inevitability, I became ill halfway through the month, and a test confirmed that this was Covid-19. As a result, I finished my last roll of film while isolating at home.

The camera I had picked for the #shittycamerachallenge was the Coronet 6-6. I felt it fitted the spirit of the exercise due to being largely made from plastic, and with the most minimal user controls - and also that the camera had mould inside the body when I first opened it. The camera's name is sometimes written as the Coronet 66; above the lens, the two numerals are separated by the coronet logo, and, taking nominally 6x6cm images, no doubt the name would be said as "six-six" (it's also worth remarking that Coronet made a 127 format camera called the Coronet 4-4 from its negative size, and this is written on the camera as '4-4'). The Coronet 6-6 is a simple point-and-shoot Bakelite-bodied camera from the 1950s, using 120 medium format roll film, taking twelve 6x6cm images. This camera belongs to a class of mid-twentieth century cheap point-and-shoot models which can essentially be considered derivations of the box camera, and, as with the Coronet 6-6, not necessarily as well featured as many of those box cameras. These cameras also tend to reflect the availability of new materials: Kodak's Brownies began with cardboard bodies, before being replaced by metal; by the mid-twentieth century, many of these cameras were made from early plastics. The Coronet 6-6's body is made from Bakelite, one the most popular plastics of the era.

Coronet 6-6 camera
The Coronet 6-6 was manufactured by Coronet, a Birmingham-based company specialising in a broad range of cheap cameras, many of which share very similar features across different models. The Coronet 6-6 is clearly based on the body moulding of the Coronet Cadet and the Coronet Flashmaster, but with a different lens and shutter unit: the wider-angle lens of the Coronet 6-6 allows for a more compact camera. The Coronet 6-6 was also the basis for the Coronet Rapier, which uses an internal mask (and a different position of red window) to achieve sixteen 4x4 exposures on 120 film. (There is also a name variant of the Coronet 6-6 which has 'Flashmaster' on the name plate under the lens, but this is otherwise exactly the same model; there's also a variant of the Coronet Cadet which looks the same as the 6-6).

The Coronet 6-6 has fixed-focus meniscus lens, which looks and feels to be made from plastic. The focal length is reputedly 65mm, which gives a wide-angle image on the 6x6 format frame. Behind the lens and shutter is a metal plate with a smaller aperture punched into it, possibly around f11 or slightly smaller, such as a non-standard setting like f14. The shutter has a single speed, possibly around 1/30th to 1/50th, and is not provided with a bulb or time setting: it does have a flash sync for a proprietary flash, connecting to two metal ports on the side of the lens unit, as seen in the image above (an image of the flash here shows it to be almost as big as the camera). The viewfinder, placed directly above the lens, is of the reverse Galilean type. Frame advance is manual, by turning the large plastic knob to the side of the viewfinder, and using the red window on the back of the camera to follow the frame numbers on the film's backing paper.

Coronet 6-6 opened for loading
The back of the Coronet 6-6 is made from a piece of stamped metal with riveted spool holders and pressure springs. To load the camera, two catches either side of the camera, to which the carrying strap is attached, slide downwards, and the whole back slides off. Inside the camera, the Bakelite behind the lens is painted with a matte black, presumably to cut down on internal reflections from the smooth surface of the Bakelite. Loading film is simple: the take up spool is placed under the advance knob on the sprung spool holder, the new roll of film positioned in the other holder, and the backing paper stretched across to the take up spool. There is a serial number on the inside of the camera back, printed in very blotchy paint, a little hard to read.

I shot one roll of Ilford HP5 Plus with the Coronet 6-6, and two rolls of Fomapan 400. Although both are 400 ISO films, even on sunny days, due no doubt to the late time of year, these were not overexposed. I often read opinions online that, in box cameras (and the Coronet 6-6 can be considered a box camera here) one should use a slow film, as this is what these cameras were designed for. Indeed, the cameras were designed for films which might have been the equivalent of 25 ISO, but they were also intended to only be shot handheld, outside, in sunny weather in the summer months. Using a 400-speed film means being able to use the kind of simple camera that the Coronet 6-6 is in more conditions than those originally intended by the manufacturers, November in the northern hemisphere, with short days, sometimes sunny, sometimes very grey, embodying such conditions. The image below for example, looks like it was shot at dusk (helped, of course, in that interpretation by the lit streetlamp); it was actually taken around noon, but on a very overcast day; with a 100 ISO film it would have been quite underexposed. With a single shutter speed and aperture setting, when using the Coronet 6-6, to get acceptable results in a variety of the lighting conditions relies heavily on the latitude of whichever film is used; far better to use a faster film and potentially overexpose it for some shots, than a slower film and not take a shot because the sun isn't shining.

In use, I found the wideness of the lens occasionally surprised me: I'd see what I thought might make a fitting subject, raised the camera to my eye, then realised I had to get closer for a composition anything like what I had thought I'd get. I also hadn't anticipated how slow the shutter was - after developing the first roll from the Coronet, a number of exposures had camera shake. This is also partly due to the shutter button, a big plastic lever offset from the lens. There is a small amount of travel which evidently tensions the shutter, but then it gets quite stiff just before the shutter actually releases. It is also quite flimsy, and bends backwards, and on occasion got caught on a small protrusion on the moulding behind it, none of which made for a smooth release. I was more conscious of this as I shot more with the camera.

The lens displays all the classic aberrations one would expect from a plastic meniscus: the above image, from my first roll through the camera, does have some camera shake, but also clearly evident is pincushion distortion, seen in the verticals. Without camera shake, the lens is moderately sharp in the centre, but this falls off quickly towards the sides and corners. I haven't used colour film with the camera, but no doubt some chromatic aberration would be seen. Also discernible is astigmatism and coma, flare, and in a few shots what looks like internal reflections, despite the matte paint. Given the limitations of the lens, it's quite understandable that there would be a version of the camera which only used the central portion of the image in the guise of the Coronet Rapier. The fact that the Coronet 6-6 uses medium format film is somewhat negated by the qualities of the lens: unlike a Kodak Brownie (and there are simple box cameras with much better lenses), for example, here the larger negative format is lost on the poor definition of much of the image.

Being aware of the limitations of the Coronet 6-6 meant I sought out subjects and compositions where these limitations either didn't matter, were less obvious, or even added something to the image. With the photograph above, some vignetting, and falling off of definition helps with the sense of depth recession, enhancing the concentration on the lit leaves in the middle of the frame. I also tended to avoid any compositions with clearly rectilinear subjects, choosing more oblique angles where appropriate.

Sometimes none of these approaches really worked, and the photographs that resulted were just unsatisfactory, despite whatever impulses made me press the shutter at the time; frequently, the wide angle of the lens, the lack of definition towards the edges and other aspects just produced images which had a distracting 'busyness' to them. However, the pleasure in using a simple point-and-shoot camera like the Coronet 6-6 largely resides in the fact that the operation of the camera is entirely about the subject and composition with no other concerns in the taking of the photograph.

Agfa Isolette III

Agfa Isolette III
Agfa's Isolette range of 6x6 medium format folding cameras are still very much well-used and well-liked, judging by the numerous references and results among film photographers online, a good sixty years since the models were produced. My own experiences with the Isolette are limited and recent, having bought an Isolette III earlier this year at a Stockholm flea market for 200SEK, but I had used an Agfa Record I for a number of years, and the Isolette's construction, styling, design and user experience are all very similar to the Record 6x9 cameras. The Agfa Isolette cameras take 6x6 images, although a couple of the Isolette models had masks for smaller formats. The Isolette III was introduced in 1954, snd is essentially the same camera as the Isolette II with the addition of an uncoupled rangefinder.

The Isolette cameras were provided with lenses of both 75mm and 85mm focal lengths, which are dependent on the lens' widest aperture: f4.5 lenses on the Isolette are 85mm, while f3.5 lenses are 75mm. I've preciously had a couple of medium format cameras in the 6x6 image size with 75mm lenses, a common focal length, but I've sometimes felt it a little too wide on the format. However, it may be worth bearing in mind that the 6x6 format came about with the twin-lens reflex camera, the typical construction of which would not have been conducive to changing the camera's orientation had it shot a rectangular image, and so the square format allowed cropping in either orientation as much as being used full-frame. Using the full, square frame, I find achieving satisfactory compositions require more thought than a common rectangular photographic frame; conversely, it seems a shame to crop the image to do so and not make use of the whole negative's area.

Agfa Isolette III lens and shutter detail
My model has Agfa's Apotar lens in a Pronto four-speed shutter, both being among the cheaper variants available. The Apotar is a triplet lens, but, being post-war, it is coated. The Apotar was the middle of the range of lenses: the lowest priced lens was the Agnar, the lens that my Record I came with, even so it did provide very good results on modern medium format films. The Isolette has focus below 1 metre, although the 1 metre is the last mark on the focus ring (possibly the lens focusses down to 3ft which would be marked on US - under the Ansco name - or UK export models). The marks at 3m and 10m are picked out in red. The Pronto shutter has four speeds 25th, 50th, 100th, 200th, plus B. The addition of the camera's rangefinder meant that unlike other Isolette models, the III no longer sports a T setting (I personally find shutters with a 'T' setting more useful then a 'B'). Other features mark my Isolette as a later version, from 1956 onwards: there is a film reminder dial on the top left of the camera instead of a depth-of-field calculator, the DOF indications are around the lens instead (the film reminder has old DIN speeds of 23/10 - 21/10 - 17/10 and COL T - COL K - COL NT). Film advance is manual, using a red window on the camera back but it does have a double exposure lock on the shutter release: after exposure a small round window shows red until the film is advanced and the lock disengages. The shutter can still be tripped by the lever around the lens when locked.

Agfa Isolette III top plate
The camera had two problems when I bought it: the camera back did not close tight at one side; and the rangefinder wheel was immovable. The first of these problems was solved by using pliers to bend inwards one of two prongs to provide a tighter fit with the camera back's latch (when in Stockholm itself I realised this might be a problem and simply held the back tight when shooting - although on some exposures I wasn't careful enough with this and some show the top right corner of the pressure plate not keeping the film in alignment, falling behind the plane of focus).

Detail of loose catch
I didn't have the tools to attempt to fix this or the rangefinder while in Stockholm. However, as the rangefinder is uncoupled, the fact that it was stuck did not interfere with using the camera, it merely meant estimating distances, and paying more attention to the DOF scale around the lens. Despite these issues, I liked using the Isolette III enough to use it while in Stockholm rather than the Baldalux 6x9 camera I'd brought with me, and shot a number of different films with it, Rollei RPX 25 and 400, Fomapan 400, Superpan 200 and some Kodak Verichrome Pan with a "develop before" date of October 1969.

Flea Markets in Stockholm

Front left:Agfa Isolette III; right: Vito CL; behind: Instamatic 300
In Stockholm recently, I visited two of the local flea markets there during my stay: the Sunday market at Hötorget, and the all-week around covered market, Loppmarknaden at VÃ¥rberg. The overall quality of the stalls at Hötorget was better, while Loppmarknaden, which is an underground hall in the shopping complex attached to VÃ¥rberg Tunnelbana station, some of the stalls appeared to be little more than just piles of household rubbish. This market charges an entry fee at weekends, but I went on a weekday. There were many digital cameras from about a decade ago, a number of older SLRs, but the only camera that caught my eye was an Agfa Isolette III. This looked in good condition, although a bit dusty, and everything worked except for the uncoupled rangefinder, which was stuck on the 10m mark. This may be easy to repair, but as it is uncoupled, this does not affect the camera's operation, simply meaning that guess-focussing has to be used. What piqued my interest sufficiently to buy the Isolette was the half-used roll of film inside. The seller wanted (and got) 200 SEK, just over £15. I finished the roll of film in the Isolette at VÃ¥rberg, in the market and at the station adjoining it. Stand developing the film, Kodacolor II, in RO9 One Shot for an hour at 1:100 resulted in a few faint images, no negatives came out from before the few that I shot with it, and the best, if rather fogged, image was of the ramp to the platforms of the station.

I returned to the Hötorget market a week on from my first visit, which had been on Easter Sunday. It was busier, with more stalls, some of which were the same as the previous week, I found a Voigtländer Vito CL, which, although dirty, looked in relatively good condition, and its shutter fired and the lightmeter was responding. I asked how much and was told 100 SEK; the same stall had a Kodak Instamatic 300 which had a part-used film cartridge inside. As with the Isolette, the part-used film was intriguing, and the seller gave me both cameras for 100 SEK and put them into a hessian bag. I shot the rest of the film at the flea market while there, then later I cut open the 126 cartridge, removed the 126 film for safekeeping until development, and loaded the cartridge with a length of Agfaphoto APX 400 taped to the backing paper. I shot this film a couple of days later. Using 35mm film in the camera provided problems that I have experienced before with the film's perforations not always coinciding with the holes in the backing paper, leading to gaps and overlaps in the exposures, and tears in the film where the advance had to be forced. The original colour film from the cartridge was stand developed in RO9 One Shot 1:100 for one hour, and the APX 400 developed as normal. The Kodak Instamatic 300 does have a selenium meter to control exposure, and, although the shutter fired, it was hard to tell whether this or the aperture changed with the light conditions. The 400 ISO film was mostly shot with a deep yellow filter taped over the lens and the negatives do not appear overexposed; the Kodacolor VR film from the cartridge (dating from 1982-86) was too dense to scan once developed, although images are visible.
