I own a very old Yashica TLR (Twin Lens Reflex) camera. (I'll put an image of the front of the camera in the first comment box below.) I didn't actually buy this camera on purpose. It came in a job lot of old cameras that I bought on eBay. I was really after a couple of Contax SLRs that were in the same listing so when this arrived as part of the lot I put it aside thinking when I get a chance I'll do a bit of research on it. In fact I knew nothing about TLR cameras other than they were old technology, having been replaced for the most part at least by SLR (Single lens reflex) cameras in the 60s.
So eventually I did research this camera and what I found out was pretty interesting. There is still a large community of photographers out there using TLRs and shooting on 120 film. In fact there are still some brands being produced today, including the Rolleiflex brand which many will recognise.
I wanted to find out if my Yashica actually worked so bought a roll of B&W 120 film and ventured out last summer to shoot my first ever roll. Two things were evident - one, the camera was fully working, and two, I am a crap photographer using this camera. Out of the 12 shots I eventually took there was nothing much to redeem any of them (perhaps one that I personally like but which I know if I posted on Flickr would get completely ignored). But I am stubborn if nothing else and on Sunday or Monday coming I am going to go into London with a fellow TLR owner and we are going to try to shoot some London alleyways. Hence my thought to post this picture. Hopefully the weather will cooperate as these cameras need a lot of light, shooting it in dull or heavy overcast weather just won't work without a tripod.
The good news is that while the Contax cameras in the job lot were both in good condition and working, in terms of value this old Yash is just as valuable as either of them. Now if I could only learn how to get the best out of it!
Shot on a Meyer Optik Gorlitz Primoplan 58mm f/1.9 vintage lens which incidently is the same age as the Yashica TLR, both are 65 years old!
This morning I decided to tackle the Copal No. 3 shutter that my Schneider Symmar-S 240 lens is mounted in - the slow speeds didn't work at all. So I took it apart and cleaned the slow gear train. That's all that was needed!
This is a test shot I made at dusk, on Bergger Pancro 400, processed in D-76 1:1

Another shot from my visit this February during a major winter storm. A good portion of the second afternoon of shooting we were given a break from the clouds and snow and I was able to take some wonderful photographs that captured some amazingly blue skies against the white and grey of the snow and granite walls of Yosemite Valley. This shot was taken with Kodak Ektachrome E100G Professional, which really brings out the wonderful colors that mother nature provided that afternoon.

An afternoon shot from Tunnel View on the second day of my trip. Over El Capitan you can see the storm clouds as they are starting to roll back in. This shot is about the only one that I got that afternoon where you can see much of Half Dome as the clouds seemed to hang over it all day long.

During the fall and winter months Yosemite Falls can slow down to a barely visible trickle. However, once springtime hits and the snow starts to melt, Yosemite Falls hits it's stride. If you look at the granite wall and notice the dark area surrounding the water that is currently there, you will see just how large it is when going full force.

Copal is a Japanese company making camera shutters and based in Tokyo.
The Copal leaf shutters are used on many rangefinder, TLR and view cameras. They are high quality shutters which tend to cost less than Compur shutters.
There are several variations of the shutter. Some use a simple inertia gear set to regulate speed. Other Copal shutters, such as the widely used MX, obtain a wider range of speeds by using a typical escapement, but have the same basic design.
Copal also made focal plane shutter units, mainly for Japanese SLR cameras.
A leaf shutter is a shutter made of a series of overlapping metal blades arranged in a circular pattern, usually positioned near the iris within a lens. The blades are attached to a rotating ring by pins at their ends, and are opened and closed by turning this ring. Various spring and clockwork mechanisms in the shutter are used to control the delay between opening and closing the blades, and hence the exposure time.
The biggest advantage of a leaf shutter is its ability to be synched with a flash at any speed. This is because unlike a focal plane shutter, a leaf shutter fully opens even at its highest shutter speed.
Common types of leaf shutters are the Compur, used on many makes of cameras, and those made by Copal.
Leaf shutters are sometimes referred to as "between-lens" shutters. This is because there are usually placed between the lens elements. However, some leaf shutters are placed behind the rear lens element, and can be called "behind the lens" shutters.

Cosina's basic camera platform was adaptable to lens mounts other than Pentax K. Here we see Cosina-made models for K-mount, Olympus OM, Canon FD, and Leica 39mm thread mouts.
The Japanese firm Cosina has a long history of manufacturing cameras for sale under the branding of other camera companies, dating at least back to the Argus/Cosina STL 1000 of 1970. In the 1980s, Cosina developed a basic kit of parts for a manual-focus SLR based around a vertically-traveling metal-bladed shutter. This platform was later transformed into a bewildering variety of other camera models.
While some point to the CT-1 as the ancestor of all these cameras, it may be more useful to point out the Cosina CT1 Super, circa 1983. This is the model which brought together a 1/2000 sec. top shutter speed and the 3-LED metering display ( - o + ) for the first time, features which define the most ubiquitous Cosina-made SLRs, right down to the Nikon FM10 which is still sold today in 2015.

I left the camera on the automatic setting, but also used a Sunpak Auto 300 flashgun with coloured gels taped over it. The aperture was set to f11, so as the daylight faded, the shutter speed got slower and slower, running up to several seconds by the time it was dark. The result is that there is a well defined sharp image caught by the flash, with a blurred long-exposure image superimposed.
The film is Kodak ColorPlus ISO200 film from Poundland, processed in the Tetenal C41 kit.

The Chinon CM-7 is quite an obvious derivative of the CT1 Super, aside from the altered shape of a few plastic moldings. Both are SLRs using the popular Pentax K-mount bayonet. The Ricoh KR-5 Super II really ought to be in this comparison as well.
Note that this particular Chinon has had a replacement of its rewind crank, which originally was an exact match for the CT1 Super.

The family membership of all these models is most clearly seen by looking at the bottoms. While the plastic molding is not 100% identical in each case, the locations of screws, battery compartment, tripod socket, and even the raised nubs to reduce scratching of the surface are all in identical places.

The Canon T60, in front, differs from the others shown here in using an electronically-timed shutter with different specs. (It is very similar to the Cosina C2.) The family resemblance still shows through in the details of the rewind knob and ISO/ASA dials.
