Hey, so I just received the 12-40 zoom to see if I like it more than the 12-60 I've been playing around with (I have an E-M1). Price is somewhat an issue; for the price of the 12-40 I can hang on to both the 12-60 AND my 50 f/2 macro, which is a BIT long but yields great results. Upsides to the 12-40: 1) Balances slightly better on the E-M1 than the 12-60 2) Focuses a bit closer than the 12-60 (1:3 vs 1:3.6) 3) Almost exactly one stop faster at 40mm 4) Manual focus clutch whereas 12-60 has to rely on full time manual focus override Downsides to the 12-40: 1) Price. I got a great deal but it still works out to about twice what I paid for the 12-60 2) The zoom doesn't seem as smooth at the wide end as the 12-60 Upsides to the 12-60: 1) Goes to 60mm, which is handy 2) Uses 72mm filters, same as the 4/3 9-18 2.5) Since I'm mainly using the 4/3 9-18, 50mm f2, and occasionally the 4/3 70-300, using the 12-60 would be nice because then I leave the MMF-3 on If I were to keep the 12-40 I'd probably sell the 50mm f2; I really like the bokeh of the 50mm and feel that for a lot of objects even f2.8 doesn't yield enough blur. I don't even do THAT much macro but it's a fun lens and I'll probably regret selling it. What do you guys think? Any thoughts would be appreciated. And I'll just put it out there: I spent something like $385 on the 12-60 and $325 on the 50mm f2. I got a great deal on the 12-40, but it still comes out to a bit more than those two lenses combined.
