Figure 1: Three old film camera lenses – a Tokina is mounted.
Who shoots green mode anyway? Sure, using old film lenses limits the number of modes you can use on the K5. For the lenses shown, only Av (Aperture priority) and M (Manual) modes are available. But Av is about as automatic as I want in most cases. I like to have the diaphragm and the ISO completely under my control.
