I have a heavy tripod with leveler and gimbal. With the K5, I also get image stabilization (up to 800mm) and focus-confirmation and (native) focus trap (catch-in-focus as it's called in Pentax lingo). I use it a lot, like for the duck shot i shot & posted yesterday (also my avatar). The attraction to the 120 is not so much reach, but aperture. I'm having a terrible time focusing at f/11 with my 400 f/5.6 + 2x TC. Past f/8, I also lose focus confirmation and focus-trap. I'm not too keen on using TC on an f/7.5 lens because of this. With the TC on my current setup, I'm also getting a lot of noise when i'm shooting at f/12 or f/14 (i need to stop down a little). It even takes time for my eye to get accustomed to the dark viewfinder. I know, the size... and weight... Ugh! It's a major concern. And pretty much no travelling with it...In Japan, the Kowa costs 1900 euro, or about 1600 gbp, MUCH cheaper than in England! So it's not much more expensive than the 120ED...It's also hand-holdable. Is the ED80 hand-holdable? Are you using something other than the usual Crayford focuser? There's no denying the ED80 is a great value!Decisions decisions... Thanks again for your help!</blockquote>
