請問如何將Nikon鏡接上Pentax的K-m(KAF3、KAF2、KAF、KA、K 接環)機身上，是否完全沒辦法？

請各位Nikon師兄不吝賜教！

[Obi-Wan]

Pentax K lens mount distance 45.5 mm
Nikon F-mount mount distance 46.5 mm

if pentax lens mount on Nikon body, u cannot focus to infinity unless the adapter has lens element

if nikon lens mount on Pentax body, since the difference between the 2 mount distance is just 1 mm, it would be very very difficult to product an adapter with just 1 mm thick & strong enough for the lens (of course u can increase the adapter thickness, but then u can't focus to infinity unless the adapter has lens element)

THEREFORE, no hope

(correct me if I am wrong)

go to
http://en.wikipedia.org/wiki/Lens_mount

goto the bottom, there is a table, those lenses > 45.5+ around 2mm should be ok
(from Leica R to below)
DO NOT buy those adapter with lens element inside the adapter!

Hi Obi-Wan,

Why we should not buy adapter with lens element inside?
Is it not good for image or will it damage the carmer/lens?

many thanks

[Obi-Wan]

because the quality would be very very poor

OIC,
