I’ve done a thing I never thought I’d do, and bought an SLR that is not compatible with my Pentax kit.
Up until now all my SLRs could share the pool of lenses. This new one stands alone.
Why was my head turned? A cheap and interesting lens. It was the beginner’s kit lens at the time this camera came out in the late 70s, and probably since. It’s 55mm focal length and f2.2. So far, so modest, but I heard it could give interesting results. It has four elements in four groups and the online wizards say it’s a Zeiss Unar design. This is the ancestor of the Tessar, the difference being that the air-gapped pair of rear elements in the Unar are cemented together in the Tessar. So you could say it’s not as good but cheaper to build than a Tessar.
I had a bit of fun (true for small values of fun) a while ago comparing bokeh and rendering between different types of 50mm lenses. What I hadn’t got at the time (or since) was a five element lens. I didn’t even know there was a design with four. But now I do.
It was on eBay as an Adaptall-2 fitting, which was great. It turned out to be Fuji bayonet with an Adaptall-labelled rear cap. No matter – the lens was very cheap and a bit of searching found a very cheap Fujica STX-1 body to fit it to. Even together the pair fell inside the Sunny 16 cheap shots challenge rules. We like cheap when we are experimenting.
The lens is certainly cheap. It has a plastic body and a five blade aperture. The camera is cheap too – it was Fuji’s entry model in the late 70s and early 80s. It’s totally mechanical, with a top shutter speed of 1/750. Mine has a dent on the corner and the crank is missing from the film rewind. But it works. It’s also the early version of this camera with a meter needle rather than LEDs, so it’s pre 1982, making it around 40 years old. But the meter works, so hurrah for cheap old cameras. Even so, who cares? It’s the lens I’m interested in.
So what does the father of Tessar look like? (I was going to call it John Durbeyfield, but that’s just too obscure). Quite hard to focus in dim light, but that’s more to do with the camera’s screen than the lens. It feels very plasticy – focusing it or changing the aperture feels like bits of plastic sliding on each other rather than brass or aluminium. It doesn’t rattle like some old lenses though, so that’s a bonus. Closest focus is 0.6m which isn’t bad. Some people have raved about its bubble bokeh, but I’ve seen so many adverts claiming that anything from a telescope to a microscope is a bokeh monster that I don’t really believe them.
As I’m not sure about the camera’s light seals I shot it first with the tail end of a part-used film. No light leaks apparent, so all seems well.
For the camera buffs it’s a basic SLR and works just like they all do. The shutter speed range and the one in use are visible at the left of the viewfinder with the meter needle on the right. A half-press on the shutter button switches on the meter. There is a lock for the shutter release so it’s safe to leave the shutter cocked. This is a cheap and basic camera that would (and still does) do the job. The only real drawback, then as now, is that you are largely confined to Fuji lenses. The flange distance was less than M42, so there was an adapter available at the time that could get you access to a wider range of screw-mount lenses. Whether the adapter is still available I don’t know, and I have no wish to use this camera with my M42 lenses – this is to mount the mighty Unar.
So how did it handle? Like a film SLR. All the usual controls in the usual places. A little limited in bright conditions by the low top speed, a little limited in dim conditions by the small maximum aperture and a dim focusing screen. And the lens? At the usual range of distances and apertures, just like any other standard lens. I’m not going to point it at a resolution chart or even a wall – what’s the point?
These are the first shots out of the camera. First test of course is to recreate the bokeh shots I did, but using Wilson’s fruity friend.
Nice and smooth with a hint of double image in the white bench.
The possibility of a bit of swirly in the background.
Again, nice and smooth. A bit of double image or outline in the strand of plant, which mean it may well do the fabled bubble bokeh.
Still, for what it cost this is fun. Fun enough that I used it for the Casual Photophile Challenge.
PS – the Classic Lenses Podcast then did an episode on this lens. Looks like mine is a good one for not being cracked.
