Komura 105mm 3.5 LTM (First Roll)

I finally got back my first roll of film (Kodak 400 C-41) with the Komura 105mm 3.5. The infinity RF setting showed me non overlapping images, so I suspected that the RF was off, but the images show reasonably sharp images. The lens is not large, but it is larger than the Canon 100mm 3.5.

I picked twelve images from the frame. Many shots were taken at 5.6~8.
By the way, the lens has a very nice finishing and it is well built. I have been told that I have slightly overpaid. Oh well.

I think that the lens does not need any adjustments/shimming based on these images. Do you agree?

It looks like the RF and actual focus agree. Try a shot wide-open at infinity. Sometimes I use a piece of copper tape over the RF cam to build it up. They can get worn, and thrown off.

Brian,

I will take a photo wide open at infinity, but what are you looking for? Is it possible that the lens is OK for close-ups but not at infinity?

Very possible. When used close-up, the focus can be a little bit off and you may not notice with your test shots. Infinity is more absolute...and does not move aroung as much.

OK Boss. Will do then.

The triplet is not too bad after all.
