Spiratone 105mm f2.5

The lens – I’ve never seen one of these before. I like the 75-105mm focal length for close up photos like portraits and detail shots. I didn’t expect to find a lens this nice for just a few dollars at a thrift store, but this one is very clean, and seems very well made.

Test shots. I believe all of these are wide open at f=2.5.

This shot is at the closest focus distance, and the background is almost at infinity (sun coming through far away trees).

I’m not sure how easy it is to find one of these, but if you do, I recommend it.

X-Fujinon 50mm f1.9

X-Fujinon lenses use the Fuji Photo Film Co. X Bayonet mount, not to be confused with the new Fujifilm XM Mount for their mirrorless digital cameras.

This lens, the 50mm f1.9, had to have been the standard kit lens for the Fuji line of lightweight (plastic) SLR cameras. There is one cheaper, the 55mm f2.2, which can be found with both the earlier M42 mount, as well as the X Bayonet mount.

Overall, the mechanical quality of the lens seem very low. Except for the lens mount itself, and the aperture, everything else appears to be made with plastic, including the focusing coils. Focus is very loose on this particular lens. The glass seems to good, and overall contrast is good.

Cosinon 50mm f1.8 M42

Found this beautiful little lens on an Argus/Cosina STL 1000. As I understand it, Cosina manufactured most of their own lenses, except a few 1.2 and 1.4 lenses made by Tomioka. In test shots, this looks like a great combination of features for a nifty fifty lens. At 1.8, images are sharp in the middle, with a slight glow to the highlights, and going to somewhat soft around the edges (even with an APS-C digital sensor). Stop down to 5.6, and sharpness is great from edge to edge. I would guess this is the standard kit lens for this camera. It’s a winner on digital!

Montgomery Ward 200mm f3.5 M42

Got this along with a camera kit I bought, just for the camera strap.

This lens is super clean, I’m guessing it was hardly used, and kept in a clean location. It’s not super sharp, nor super contrasty. The colors look good, and the bokeh is interesting. The biggest disadvantage is that the minimum focusing distance is about 11 feet. So you would need a macro extension to get close to anything small.

X-Fujinar-T 135mm f2.8 DM

This lens came as an extra in a lot of cameras from Goodwill. I’m not a big user of 135mm lenses, so I planned to sell it after a quick test. I used the lens for a visit to the Fort Worth Zoo, and now I’m not sure this is one to sell, it’s light, images are sharp and have nice contrast, which makes it easy to focus with a mirrorless peak focus assist.

Asahi Pentax Auto 110 System

I lived through the 70’s and 80’s, but never heard of the Auto-110 system until 2015, when I started looking for interesting lenses to connect to my Fujifilm X-E1. The Auto 110 is one of only a few SLR cameras designed for the 110 cartridge film format. Because the registration distance is very small, and the lenses are only made to cover the film size of 110 (13 mm × 17 mm), the lenses will only work on smaller digital cameras, like the X-E1, or MicroFourThirds cameras.

Here is the first set that I bought, which included the camera, a flash, auto-winder, and 3 lenses 18mm, 24mm and 50mm. Now if you want to use the Auto-110 system with film, you can still purchase new 110 film cartridges from Amazon and eBay.
