You should read more carefully. None of what you said is related to my response. * Of course the only way to focus an old Pentax lens is by the lens.. I didn't say anything contrary * I wasn't talking about any other 5D nor making a comparison. In the case of the 5D, you have the option of using the Optical viewfinder to manually focus lenses.. this is ideal. LCD attachments for the 5D were specifically motivated by the video enthusiasts. Neither is not an option on the E-P1 suggested which provides only a rear LCD to focus. * I wasn't making a reference to everyone else's preferences towards EVF. I was stating that without EVF the Pen isn't ideal for manual lenses. Add the EVF the Pen is no longer "inexpensive". * I didn't say that the EVF was the only way to manual focus on Pens. I said it was uncomfortable to focus using just the rear LCD. Adaptation of many older lenses (K-mount included) is right up my alley... I do this all the time with Pentax and micro 4 3.
