CURRENT OPTIONS - If you see my gear in my signature, you'll notice my best option for creamy bokeh is the PM2 with 135/2.8, but it's too long for most purposes and the 50/1.7 really shouldn't be shot wide open. Plus my max tolerance is ISO6400 APS/MEDIUM FORMAT - Medium format is too big and expensive for me. Those Sony NEX cameras are small and nice and if I had to do it all over I might, but that APS sensor doesn't give that much more blur to warrant an "upgrade" (I prefer m4/3s in every other instance). NEW M4/3S LENSES - I could buy a 75/1.8, but it's a bit long for many instances so I'd need a shorter companion with as much bokeh: the 42/0.95. But the problem is that shooting it wide open compromises image quality as would the ND filter I would often be using in sunlight. These two lenses are nice, but their "downfalls" make me question spending $1600 for more background blur. FULL FRAME - Next is full frame. I loaded up my old 35mm film camera and shot it with the 50/1.7 and 135/3.2. I liked the results so I'm considering Sony full frame mirrorless. Although more boxy with a dumb orange ring around the lens, it's smaller than an EM-1!. I could get a body for around $1600 and with some cheap adapters I could use the same lenses. The A7s I can shoot ISO6400 all day long so doesn't need IBIS. FULL FRAME LENSES - I already have a smallish "kit" - Vivitar 28/2, Pentax 50/1.7, Konica 135/3.2. If I bought a lens it would be an 85/1.8 or so for $300 and that would probably be on the Sony most of the time. I'm planning to buy a Vivitar 70-210mm 2.8/4 anyway and that would probably be a good match here too. Plus, based on how good these lenses are on m4/3s and how crappy they are on my Pentax Q, except for the corners, which I'm planning to have blurry anyway, I'm assuming these would all be even better on full-frame. WHAT TO DO WITH M4/3S GEAR? - I'd keep the PM2 because it's just so good and versatile. Look at the fisheye. Or the size of a PM2 with the 14, 20, or 12-32. I really wouldn't need to buy any other lenses as the adapted ones would work on both cameras. And I could probably sell off a few things I really don't need anyway. I wish Sony wasn't the only one making FF mirrorless. I wish it didn't have the viewfinder hump so it would be smaller. I wish the Sony RX1 either had interchangeable lenses or an 85mm f2. Either way, what do you guys think about buying a FF camera instead of better m4/3s lenses?
