I am a big fan of manual focus legacy lenses and up until recently it was pretty much all I used on my EPL-1 (in fact it was the reason I bought an EPL-1 in the first place). Now I am faced with some vision issues that are making me realize that it would be good to have at least a few AF lenses to play with so I have been selling off most of my keeper MF lenses and keeping only the a few that I cannot bear to part with (a couple of Pen-F lenses, Super Taks and a Helios 44). I have an Olympus 17/2.8 that I really like and I picked up a 14-42 kit lens that is proving to be more fun that I would have guessed.So here is my question...the sale of my lenses means I can probably pick up a Panny 20/1.7 if I'm patient (and quick on the draw). That said, I have the 17 and I have never felt that I NEEDED a 20/1.7. I know its supposedly an outstanding lens but I like the 17. I even started a thread talking wondering why the little Oly lens wasn't more well liked. My other option would be picking up an m.zuiko 40-150. Now, this is another lens that does to seem to be particularly popular but as I recall the same lens on 4/3 (I took one to Spain and Portugal last Summer) was pretty nice to have. Finally (again from my Spain trip) I used an Olympus 4/3 14-54 for most of my shots and I have to say I think that is one hell of a lens. It's the ONLY thing I miss about my E520 compared to my EPL-1. I suppose I could adapt one to my EPL-1 but that doesn't seem like it would work that well. Any suggestions? Oh yeah, I almost forgot...what I want is to have nice little flexible kit for travel. I'm going for my doctorate and aside from being a penniless researcher I expect I'll be doing a fair bit of traveling. Portable is going to be very important. Good image quality is important but I'm happy with the 14-42 and the 17 so the bar isn't set all that high.
