Well, my 60mm f/2.4 came in today. I had the 18-55 f/2.8-4 for a while, and while my first copy was OK, it wasn't great at 55mm, and every once in a while it would throw out a complete garbage image for no good reason, and I suspected potential problems with the IS mechanism. So I sent it back for an exchange, and the second copy I got was absolutely abysmal at 55mm. I mean horridly soft... I'm sure an element was severely out of alignment. Anyway, I had that copy for 2 days before requesting another RMA. While I generally liked the convenience of the 18-55, I didn't really want to take another chance on it, and B&H was great in accepting the return again. I opted to have them send the 60mm f/2.4 instead, so I'd have a good setup with the 14/35/60. I've only taken about 6 test shots, but wow...did I make the right choice.
While the AF on the 60/2.4 is dog slow if you need to go through the whole range, it's OK if you're in the vicinity, so for most work it should be fine. But this thing is SHARP. Really sharp. Build quality is really exceptional as well and the hood (while huge) is all metal and clicks into place great. Makes me want to shake Olympus and say "See...Fuji can include a high quality metal hood with their telephoto lenses....stop charging $80 for the hood for the 75mm."
Need to take more images, but this is a seriously impressive optic.
