ok i just put this lense i had laying around in the local classifieds. Its a zeiss jenazoomII mc macro 70-210mm. problem is, i put it in there assuming it was a pentax mount, and as i was searching for prices to sell it for, others reffered to it as a pentax mount aswell... but i tried to fit it on my mothers pentax and it was a no go... someone wanna do me a favour and post a photo of the mount on one of your nikon mounted lenses? i vaguely remember when i picked it up something about it being nikon mounted. I need to correct the add soon if i am wrong. thanks!
