Help with my 15mm... do not fit right on the camera

[RIVI1969]

Hello,

I have a brand new CV 15mm that just arrived from Cameraquest. The 28-90 mount fits fine, but when I screw the lens on the mount it stops off the center, so I don't know if this matter affects the pictures. I just use it a few times so I don't know if the blurry pictures I get are from my mistake or from the lens. I took a picture from the camera with the lens I wonder if I can upload it so you can see it.

Any help will be very appreciate!

Kind regards
Ricardo

Ricardo,
I dont have the CV 15mm, but I have tried it in the past, but do not remember the centering. It is though common with a screw to M adapters on the R-D1 that the null focusing mark no longer remains central.

When viewed from the above/back of camera my 21mm Avenon with adapter is slightly right of centre and my 28mm CV Ultron is slightly left of centre (no consistency). Provided the lens is fully screwed into the adapter focusing will be fine.

The CV 15mm is not rangefinder coupled so you have to set the distance by scale. It does though have great depth of field so I'm suprised you are having problems. Make sure the lens is scale focussed on infinity and try some pictures of buildings at more than 25 meters. Check the focus on these or up load here. They should be sharp. If not perhaps your lens is faulty.
