I purchased the 45 1.8 with great expectations, and it is a great lens, but my 45 and my EPL2 did not get along. Far too much focus misses. Not just catching the background, but the whole image out of focus, and refusing to come into focus without intervention (focusing on my hand, etc.). So, I re-bought a Takumar 50/1.4 and might also try an FD50 or OM50 (or maybe even a PL45) for my moderate telephoto. If I'm going to work that hard at focusing, it might as well be for 60, instead of 400, dollars! If Oly releases a FW update that helps, I might buy back in later down the road. In the meantime, I've finally sprung for the lens I've wanted to try since it was announced. The PL25. I am really a normal view shooter, with my favorite two combos of all time being the Canon 35/2 on my old XTi (my first DSLR) and later my all-time favorite -- the 50/1.8 on a 5D. I am hoping this 25 will get me closer to what I want than what the 20/1.7 has given me. Don't get me wrong -- I may not be selling the 20. Time will tell. That pancake form factor is great! But I find the lens lacks a little contrast, and the 2/3 stop doesn't hurt with the PL25 either. I've read the reviews, and the rendering looks lovely. I also read the reviews about the dreaded rattlesnake issues, and so it was with some apprehension that I made the purchase from Unique Photo ($599, shipping was free and no sales tax). It's a lousy day today (cold and rainy), so I don't have any opportunity for sample shots, but here's some initial impressions: 1) Build Quality: The lens is what you would expect if you've handled the PL45. They are clearly related. It's not a great build quality, and there's always the "this cost $600 dollars???" question, but it's not bad. What I'm really after is the rendering, so time will tell. I do like that this lens is black (instead of the gray of the 20/1.7) 2) Focus Ring. I think someone on this board once described the 20/1.7 focus ring as turning a dead frog around a tube of grease (or something like that). Not sure what that exactly meant, but the PL25 is buttery smooth. It feels like my Takumar's ring, which is gorgeous. Having said that -- guess what? No AF focus misses so far (of course, no field testing yet). So, we'll see how much MF I actually need, but if I need it, it's smooth as silk. 3) Rattlesnake Issue. This is not just an issue in people's heads. I've seen the videos people have posted. It's real. But, for whatever reason, it happens a LOT less on my EPL2 than my EP1 (where it happnes quite a bit). 4) unboxing. It was just nice to open a box and get both a pouch and a hood. Having tried the Oly 12, 17 and 45, it's nice to be pampered with this lens. Not sure why, but in general, I seem to be favoring the Panny primes over the Olys, with my only Oly lenses being the 14-150 and EPL2 kit lens. The native primes I like are the Panny 14, 20 and PL25. I also like the PL45, and given that I sold my 50 OM macro, I might get a PL45/2.8. 5) vs. the 20mm I'll have to post some photos when I get time to do side-by-side. So far, I've just been shooting with either/or. My initial reaction, though, is that the 20mm 1.7 is a sharper lens, but almost clinically sharp. The 25/1.4 has slightly better tonal gradients. Overall, I think because of the combination of +10mm and + 2/3 stop, the 25/1.4 gets me much more "3D" rendering than the 20/1.7. This is what I am after, so that makes me very happy, but because on balance they are DIFFERENT lenses, and not really one better than the other, it's hard to let go of one. I'll update this post with more impressions as they come in, but for now, here are a couple of pictures: my current camera trio -- EPL2, EP1 and Canonent. Then the EP1 and EPL2 comparing the PL25 to the Takumar (sorry for the cell phone photos). Here's a pic I just took tonight (random shots around the house -- only the very front tip of the boat is in focus). This was shot in RAW, and just run through LR defaults (I think I did auto WB, but that was it). I'll need to test it against my 20/1.7 tomorrow, but this is about the best color I've seen out of an m43 lens without adjustment. And the OOF rendering is really smooth. I hope this is the norm for this lens. If so, it'll be money well spent.
