Has anyone seen much less used one of these before :
Thought it might help when focusing for macro.

but since it fits around the lens, surely it would just need shimming down to the size of the focus ring for whatever lens you fancied using it for?

It'd look a bit silly on an Auto110, but I see no reason it wouldn't work on a 35mm or DSLR.
you don't have to be mad to post here



but it does help

Thats what i was thinking and he does offer reducers down to 60mm, my pentax is about 70mm across the grip on the barrell.
I will watch it and see if it goes cheaply

My though that was as it was designed for a much bigger camera, the position of the grip may not be convenient in conjunction with easily holding the K10D/K20D. It is a matter of lens to edge of camera distance. Also, as I understand it, it was really designed for quick shift lense, the focus ring travel of which may be very different from that of your lens.

Its quite a big thing and may well be ergonically out of balance with a small DSLR

Thanks for the advice, If i goes for a few bucks i might snap it up, if not i will pass on it.
It does look interesting though
