[MF3D.FORUM:968] Re: Pentax 6X7

Hi Oleg:

I am glad to see the message you sent me about the Pentax 6X7.  Also glad to 
know that you have a system similar to mine.  Yes, I am the same Kevin Chou 
that you see in the Oakland Camera Club once a month (well, I missed a couple 
of meetings lately, the date of that last July meeting I was still in my 
China vacation).  

Before I jump in with both feet for MF-3D, I have been doing some research to 
build a usable 6X7 viewer first.  One simple way is to use the vintage card 
viewer's prismatic glasses, but their optical quality are not up to par with 
what I want.  Do you know who made the best card viewer in the old days?  The 
second choice was to buy a large pair of achromats from Edmund that can cover 
the 6X7 area.  The price is almost $100 each (too high for me).

Since I am a collector of old Kodak folders, amount them, I found a pair of 
Kodak 3A Autographic cameras might just meet the need. I took the front and 
back elements out, eliminated the shutter in between, and combined them as 
one unit (3 elements in two groups).  It covered the 6X7 area quite nicely, 
and it looks good conner to conner with undetectable edge distortion.  

I am going to start my building block from here. First to shoot some 120 
black and white negs with the Pentax, I can develop the film myself anytime, 
just to try out the different stereo bases, and the mounting methods.  I have 
come to the conclusion that I might have to make my own mounts to fit my own 
viewer.  

Please let me know if you have some better ways.  By the way, I like the 
composition in most of your 35mm 3D slides that showed in the club meetings.

Kevin
