LENS REVIEW: Super Komura 90-250mm f/4.5



Sankyo Kohki was a reputable optical company and was the biggest distributor of lenses and photography equipment back in the old days. They became active in the early 1950s and went by names like Chibanon, Komura, Super-Komura and Komuranon.

Like Tamron's Adaptall system that allowed lenses to have interchangeable mounts for different cameras, Komura also produced their own Komura Universal Adapter, but they are very rare nowadays and hard to find.

Searching online, it seems there's a later version of this lens with Macro Mode. The lens under review here is that of the earlier version which comes without macro focusing.



Here's a later version, the

LENS REVIEW: Super Komura 90-250mm f/4.5
It was in such bad condition when I bought it.

LENS REVIEW: Super Komura 90-250mm f/4.5
Seriously? This is one of the easiest lenses to disassemble and clean. EVER.
Many of the ones I cleaned were too complicated or complex.

Summary


Pros

Constant aperture of f/4.5

Solidly built, all metal and very sturdy

Snappy aperture ring clicks

Smooth focus and zoom rings

It has an interchangeable mount system, like Tamron's Adaptall

Comes with a built-in hood

Very vibrant colors and nice contrast

Especially nice for doing macros



Cons

Too heavy for handheld shooting

Does not have a Macro Mode. Newer telephoto zooms usually have this.

Does not come with a tripod mount, considering the size and weight of this lens

The Universal Mount is very rare, so you're stuck with whatever mount you get with this lens

Like most older lenses, a little contrast is lost when shooting into sources of light or bright scenes



Conclusion

This lens has a very beautiful craftsmanship. It gives you the feeling that other telephoto lenses are overshadowed in terms of ease of use, design, size and weight.

The constant aperture of f/4.5 also makes this lens a pleasure to use. Add to that the vivid rendition of colors that look especially nice for macros. Image quality is good, but like most vintage lenses, it's best when stopped down to f/5.6 and lower.

My copy came with an M42 mount. Although I tried different hacks to be able to use it on my Nikon D5200, I decided it was best to leave it as it is... an M42 mount. Despite this, the lack of a Macro Mode, and being too big/heavy for handheld street photography -- I would want to have another copy of this lens if it came in a Nikon mount.

This is a good bargain and should sell around 3k Pesos in the market. If you need a good telephoto lens, grab this one when you see it.
