I sold off my DSLR stuff, but I was asked to take some pictures at an indoor Basketball game for our school. I brought my 3 cameras: RX100 NEX6 w/ MD100mm/2.5 lens on a turbobooster GX7 w/PL25 Random thoughts: The RX100 works great anywhere, anytime given it's size. With the lowish light, I used it only for wide angle (where it's f/1.7), but the focus speed, etc. was fine. Pics are fine for smaller viewing sizes. NEX6 w/MF 100mm turboboosted lens shot at f/4.0 (2.5 is too soft on this lens). I think the Turbobooster doesn't help -- making the pics a bit soft. Also this old MD lens I think is a little yellow (radioactive?) as color was off, but 100mm was the longest I would want to be at here. 4.0 was marginal. GX7 w/PL25. Got my best shots here. The 135eq of 50mm ("normal") was the right FL when under the basket in our end. AF speed was pretty much adequate for a middle school girls game. Focus point selection is not the easiest in a rush with the GX7 if you want to use the EVF. Had to switch to LCD to better use focus point select. I shot at three apertures on the GX7: 1.4, 2.0 and 2.8 At f/1.4, the lens is not at it's best, but it gets some nice "3D" pop. At f/2.0 the lens is both sharp, and the aperture is fast enough to get reasonable shutter speeds and stay at ISO1600. At f/2.8, I had to go to ISO3200, which limits the pictures to small size, and impacts cropping. What I learned for next time: Overall I think I would need f/2.0 and ISO1600 on m43 or 2.8 and ISO3200 on NEX sensor. A zoom would be preferable, but there are no zooms that do what I would need, which would be 25-75 f/2.0 in m43 or 35-100 f/2.8 for NEX. I can see why a D750 with a 70-200/2.8 would be golden here, though you'd still need a wide angle solution. I think I might have been better with 2 M43 bodies - one with the PL25 and the other with the Oly45/1.8, and the RX100. sorry no pics -- middle school kids.
