Now, let's see if B. Franklin also describes you. Isn't it the ultimate irony that all of his little tag lines actually apply so clearly to himself.

Sure, for those like you who don't know how to use them effectively (and presume to characterize cameras they're never actually used). But no problem for those of us who do.

This can't be solved with contrast focus on the main sensor nor phase focus on TTL sensors. To do it right requires phase focus using a separate, non-TTL, dual-window, dual aux sensor method. In other words, auto- rangefinder. Doug
