  1. Re: What 8x10 lens do I need for full face portraits like this?

    Eddie,

    Re-examine your comment. To achieve a specific image size (such as filling the frame with a head) in any given film format, the lens focal length has no effect at all on the reproduction...

    Air cooling cartridge brass after heating will produce a brittle result. I will say a prayer for your safety if that is how you are annealing cartridge cases. The brass must be water quenched to...

    Re: Help please - copal shutter swap?

    Cell spacing for Super Angulons and similar designs is very critical. Modern Copal shutters are held to a very close tolerance, but if you do swap the shutter, it still pays to check the final...

    Re: 135mm f3.5 Planar - keep? Sell?

    I've never seen one that actually sold for more than about $3,600 or $3,700. That would be for a perfect condition T* version, the most valuable, it would seem. I would expect the 67mm-threaded...

    Re: 135mm f3.5 Planar - keep? Sell?

    There were two versions of the non-T* marked lens. One has a 58mm filter thread, the other 67mm. The version with the 67mm filter thread is identical to the version marked T*, other than, possibly,...

    All lenses will focus to 1:1, some with better results than others.
