Hi all,

This is my first post! Does anyone know where I can see one of these manuals online or does anyone have one they can send to me via pdf file? I recently picked one up and I can't figure out what numbers on the side of the parallax correspond to which lens. It has a 50 mm lens and the other one I cant remember. Any help would be greatly appreciated!

If memory serves. on Mine 1''= 25mm, 2''=50mm 3''=75mm and so on up to 150 I think. You need to have the corresponding "finder lens" rotated in place. the 1'',2'''3'' to match the "taking lens" 25mm,50mm,75mm
I will see if I still have the Manual tonight. Try searching on line. You can usually find anything if you search long enough.
Hope that helps. and I hope I'm right!

You know the more I think about it. It might go 1'',1.5'',2'', 2.5?
I'll check it out tonight.
Sorry, I probably ain't helpin to much.

BY definition, in the USA where the Camera wasmade - 1 inch is legaly defined as 25.4 mm so your table is correct. The actual parallax knob on the back is set for the focusing distance, ie if the subject is 5 ft away you would set it at 5ft mark. I belive that iit actally tweaks the geomety of the finder itself so it probaly is constant for any focal length lens.

Thanks for the replies. I know the one on the back is for setting the distance, it's the one on the side that I am confused about. I think you are right about 1 being 25, etc. Although there are large numbers like 20 on the side that were throwing me off.
