Re: 67 - K Adapter and long lenses?

2002-05-24 Thread Bolo

 I've been experimenting with the 67 to K-mount adapter lately; haven't taken
 any pictures, but I was wondering if anyone else is successfully using this
 adapter?
 
 In particular, the view through the viewfinder is great on the 200/4 and the
 90/2.8, but a Tak 400/4 and 55-100mm look like the top 10% of the view is
 blacked out.Are there some lenses that the adapter doesn't work with?   It
 appears as if the top of the image on these lenses is vignetted;  almost as if
 the  35mm camera isn't in the center of the image circle.   Mechanically, the
 adapter is fine.

The 6x7 to k-mount adaptor allows for shifting the lens.  That allows
you to have PC (perspective correction) when using 67 lenses on a
35mm body.   Is the shift adjustment set to zero?

Mine never did, they rotated but that's it, the PC control adaptors are the  
Zörk Film  Phototechnic ones which you can see at http://www.zoerk.com/

Darn - I was dreaming of getting one along w/ the 45mm f4
if/when I can afford one. That would be an interesting rig!

I see this with my A* 200mm F4 Macro and my MZ-S.  No vignetting
in the image recorded on film, but the top of the viewfinder
fades to black well before the edge

It's more of a camera thing than a lens thing, I guess.

This is common with any telephoto lens. It's not that the image
is being vignetted, per se, you will still get full coverage on
the film, but the mirror isn't large enough to project the full
image onto the screen.
