Hi,

Just got hold of a pan cinor lens all looking great except there is a small black dot on the lens prism near the c-mount. Is this normal or is it some kind of grease?

This is normal. It is a tiny round mirror that sends the image to the viewfinder.

Cheers,

Hi,

That's good news as I was unsure exactly what was happening there. This lens is quite strange when focusing and I wanted to know if anybody else has the same issue. There doesnt seem to be a great deal of change in the viewfinder when focusing, I can see a small shift but you cant really tell if your focus is accurate. I set the lens to maximum zoom and focused from 2 meters to infinity and there isnt a huge degree of change. Is this supposed to happen or is the viewfinder for focusing only?

Many Thanks

If you have a single black dot, you have the older version which has just a plain viewfinder without any kind of focusing aid. The later models have a split-image focusing aid and inside the lens you can spot three of these black dots.

For best results, always focus at the zoomed-in position and do it quickly before your eyesight accommodates and causes uncertainty as to what is exactly in focus.

Cheers,
Jean-Louis
