Choosing the focus indicator with an "A" lens ?

phenri · 08-13-2007, 01:41 PM

I have a Tamron 90/2.5, with a PK/A adapter which makes it the equivalent of an "A" lens. I like it very much, it does a great job at portraits.

But I would like to choose the focus indicator, not be obliged to stick to the one in the center. Is there a way to do that ? I can choose any indicator when an AF lens is mounted, but no luck with this Tamron. Anyone knows of a hack ?

Interesting question. I had to go get my K100D and take a look to see, never having tried it or given it any thought before.

I have a Pentax-A lens mounted, and the focus indicator selection menu was grayed out.

I've never given it much thought because the only focus indicator I usually use with manual lenses is my right eyeball.....and a Chinese split-prism focusing screen.

I'm planning on buying my first dedicated manual lens and although i have good eyesight, focusing manually through the K10D viewfinder is a pain. Sure, it might be large compared with other digitals, but my dad's old minolta is in a different league!

Is there a way to magnify the viewfinder without vignetting or cutting out part of the frame? I'm not looking at anything silly like 2x, but something bigger would be nice! If not i might have to order a split focussing screen, but that doesn't appeal to me hugely.
