This was my first ever projector lens and a great example of a typical lens from a reasonably modern full size 35mm slide projector. It makes a great macro lens with a standard M42 to Sony adapter, and an equally good lens for normal focussing distances using an ultra-slim M42 to Sony adapter. I got this lens for a bargain price, and because this was my first ever projector lens I really didn't know what a complete bargain I had when I hit the "Buy it now" button in eBay!

Subsequent experience has taught me that 35mm slide projector lenses with a focal lens of 90mm and an aperture of f/2.4 or f/2.5 tend to be high end lenses from top-of-the-range slide projectors. And although many of these lenses have high quality metal lens barrels, while this lens is stuck with a cheaper plastic lens barrel, this lens really did blow me away with the results it was able to deliver. But I think this lens is also quite rare: I haven't seen another one since. This makes it very difficult to give any idea of what you might have to pay for one. But having used this lens quite extensively, there is no doubt that i would be prepared to pay top dollar if I ever see one again!

I used the following adapters to mount this lens on my Sony mirrorless camera:
