A couple quick shots from one of my favourite venues -- our old Courthouse in Toronto.

Nice shots, Nick.

 

The reason why you can't insert a space between the two shots is probably because you uploaded them attachments ... I guess the trick to get around this is to make two posts with one shot attached to each of them.

Here's one I shot last weekend with my M8 with the 15mm CV. Great lens.

Cool shots.

 

Just got mine but haven't sen any results yet. The 'noon' position is slightly off using either of my CV ltm-m adapters. For my other CV glass I've not worried about it, but the tulip shaped 'hood' on the 15 isn't adjustable. Has anyone seen increased vignetting as a result of this? I guess it is really a question for those that have experience with the lens on film.

It is very easy to alter the 12 o'clock position of the CV 15mm. Mine was 'off' by about 10 degrees so I followed the advice of a fellow forum member (whose name I have unfortunately forgotten) to adjust it.

 

Using the appropriate jewellers screwdriver, remove the 4 cross-head screws holding the screw mount in place. Lift it off, making sure that you note its orientation to the lens barrel (temporary marks on lens barrel and mount may be wise). Underneath you will find a thin annular copper washer with 4 holes in it, with corresponding holes in the barrel beneath. With the tip of a screwdriver, slide this washer in the appropriate direction until another set of holes appears in the barrel. Reassemble the mount making sure that the orientation is as close as possible to the original (it will have rotated by the angle between the two sets of holes). Make sure that the 4 screws are fully tightened and try the lens on the camera - if it's worse than before, you have moved it in the wrong direction and know exactly what to do to put it right...! :rolleyes:

 

I hope that this helps

John,

Thank you! The mount on my CV 25 and 75 seem to be the same. Do you know if they can be adjusted the same way? I know it dosen't matter, its just one of those little things that annoys me.:)

I don't have either of these two lenses so the simple answer is that I don't know. However, if they were my lenses and the mount looked the same as that on the 15, I'd certainly give it a try.

It works! Yay!! Both my 15 and 25 stopped just short of the mark. So noon was more like 1130. I moved the ring one hole clockwise (the lens was on the table cap down, mout towards me) on both lenses and now they're perfectly alligned. I couldn't remove the fourth screw on the 75 (drat!), so I'll have to live with it being this way, but at least I don't have to worry about the 15's tulip.

 

One thing to note is that the steel mounting plate on all my lenses have a round notch indicating the noon position of the tread. Noting this makes it easier to see what is up and about how far you have to move the mount.

 

Thanks again John.

- Carl
