p.2 #2 · Ever feel guilty "adapting" a classic lens?

How so? I thought it simply converts them to manual aperture lenses.
The problem is that the A contacts end up confusing the camera, and you lose most of the functionality of an A lens (including Matrix metering, full exposure modes and on-body aperture setting). So converting an A lens in a non-reversible manner pretty much ruins them for use on Pentax bodies. Pre-A lenses actually become more usable as you get stop-down Aperture Priority as well as stop-down manual metering after conversion.

That's good to know - thanks. I've only converted one -A or more recent lens; a SMCP-A 50mm f/1.7. It's a really sweet lens, but not a big financial concern for anybody.
