I briefly considered making the title "Disappointed in PL45" or something similar but I thought that would be just too mean. I just got my PL45 and... <a href="http://www.flickr.com/photos/dixeyk/7639836326/" title="Lovers by dixeyk, on Flickr">"1024" height="684" alt="Lovers"></a> I like it quite a lot. It's a very different beast than the O45. It's much larger (although doesn't feel terribly heavy on camera). It appears to be equally sharp with excellent color. The O45 might be a bit more contrasty but if it is it's not by much. The double switch FOCUS FULL and MEGA OIS is handy but I'm not sure when I wouldn't have it set to FULL FOCUS. The AF is very much like the O45 (hunts a bit) and maybe a touch slower but the ability to get close is really making all the difference in the world for me. I do like the rendering on the PL45 quite a lot. It reminds me of some of my legacy glass. I also got my PL25 as well and in all honesty I'll probably use that more but I am very pleased with the PL25.
