I got mine today...took it out really quickly, and took some random test shots (will post them later) of my friends during a hike, just to test it. Before the Oly, I had a Canon 5D Mark II with a bunch of L lenses, including the famed 135L. One of the best things about the 135L was that it was deadly sharp, even wide open. That lens was the reason I kept the Canon kit so long. Well...it looks like the Oly 75 is even sharper. It's ridiculous. I took a head shot of my friend at f1.8 (doubt I'll use this lens on any other setting haha), and even just looking at the JPEG on the screen you can see each individual pore on her skin. It's...ridiculous. Haven't tested bokeh yet, but I'm expecting it to be slightly less magical than the 135L, due to the smaller sensor size. Technically I'm losing 1 2/3 stops of DOF, but since the Oly's sharper, I'd say it's AT LEAST as sharp at f1.8 as the Canon was at f2.2 or 2.5...so, I'd only be losing a stop of DOF (plus, assuming my subject distance is the same, I gain a little due to the increased FL), realistically speaking...plus, I'm gaining IBIS...and the lack of stabilization was my only (but very massive) complaint about the 135L. I constantly had to watch my shutter speed and quite often (since I like to shoot at night) had to crank the ISO way up to compensate for that. I'll post up samples, but it's just nutty...I was afraid that I'd regret having both this and the 45 (which is also a great lens, though I don't think QUITE as sharp as the 75), but the 75 is (relatively speaking) a beast...weighs nearly three times as much, and is probably two or three times the volume of the 45. So...I think the 45 will be my travel prime, and the 75 will be my around-the-home-country prime. PS: I like street candids...this lens should be an absolute street candid monster when coupled with the OM-D. Do I sound giddy yet? Because I am!
