    These were done very fast and hand held so I don´t even know if it could be considered a comparison. I will try to do something more elaborate next weekend.

    Canon 5D MarkII + Canon 28mm f1.8 @ 1.8
    8700214132_8bd7c05f7a_b.

    Nex7 + speedbooster + Canon 28mm f1.8 @ 1.3
    8700213770_caeaf71688_b.

    Canon 5D MarkII + Canon 50mm f1.4 @ 1.4

    Nex7 + speedbooster + Canon 50mm f1.4 @ 1.0

    Canon 5D MarkII + Canon 80mm f1.8 @ 1.8

    Thanks RAWFA for the pics. Reinforces what I already knew- I'm not going to trip over myself trying to buy one. :)

    Something doesn't compare right to me. Were these shot at the same shutter speed and ISO, or was the exposure automatic on both cameras?

    Hmmm... Another possibility - Do you have AUTO DRO (Dynamic Range Optimization) turned on for the NEX?

    Thanks for sharing! Initial impressions are that the speed booster doesn't quite condense the image enough to include what the full frame sensor sees. And of course there's a big difference in contrast - I'm wondering how much the camera bodies play a role in this (IIRC the NEX-7 might have more dynamic range than the 5Dii).

    Still, nice to see a fairly direct comparison.

    I´m sorry, guys. You´re right, I didn´t have HDR turned on but D-exposure was on (it doesn´t take many shots and condense them into one, but it does expand the shadows).
    Iso was the same on both cameras but the maximum shutter speed on both cameras is different. The MarkII does up to 8000 an the NEX7 goes up to 4000.
    The aim of the test was to show both at maximum aperture.
    When I have time I´ll do a more fair comparison.

    No problem RAWFA, just trying to understand what was posted. Looked to me like the NEX was +1 EV or something over the Canon. Which would make sense if they were both shot wide open at same shutter and ISO. Then I realized the dynamic range was off, not the exposure.

    Pretty hard to line up the shots to get nearly the same framing too (Closest was the 50/1.4). Been there, no worries.

    Looks like sharpness is comparable, I'm more interested in the loss of contrast shown in your first set. Perhaps you can explore that more?

    The first test was a bad one as I´ve forgot to set the NEX7 to RAW and had it actually set to optimize shadows. Plus the maximum shutter speed on the NEX is 1/4000 (while it´s 1/8000 on the 5D)...so, like I said. It was far from a fair comparison. On the second comparison ALL settings were equal on both cameras and both were shooting RAW (nothing was done on post). The only setting that was different was apperture because I wanted to show how much light the SB gives you when compared to the 5D.

    Perhaps you could do another quick test in a high contrast scene?

    I could but would mean that I would have to close down the apperture on the NEX on account of the maximum shutter speed. I will actually take the NEX7 for some shots which is much more interesting than these boring shots I´m posting here :)

    Some very very quick tests while crossing the park (Canons 28mm 1.8, 50mm 1.4, 85mm 1.8 ALL wide open ALL the time)

    Ok, so I´ve finally found some time to spend with the SB. I left home at around 6:30 am and arrived back at around 10:30am. I took the NEX7 with me along with a Canon 28mm 1.8 and a Canon 85mm 1.8 (I was using a sling pocket and by the end my back hurt from the weight). I have to say that the SB is amazing, but I would think twice about taking it to a trip that required fast shooting. Focusing with lenses that are already fast takes time and a steady hand. Enough talking now....here is my series for the day:

    Those are all great shots, and I had to linger over each one.

    But they all seemed to be shot with fairly high apertures. I'm really curious to see how it performs with already fast lenses more wide open.

    But take your time, RAWFA. No hurry! :D

    On this last series I cannot recall which photos were taken wide open but ALL previous photos on this threat were taken fully wide open.

    Some wide open shots at home...go easy on the "model"...Borred at home, just out of the shower after some bad sun burn.
