    I see the Nikon D7100 has a 1.3x crop mode, giving it a 2x crop factor (same as m43). Just curious if anybody with a D7100 has compared output to an OM-D series or GX-7 ...

    Not trying to flame or bait, genuinely curious since I recently went to a D7000 from an EM-5 simply for the improved AF-C.

    If you're talking about C-AF, the E-M1 has much better C-AF than the E-M5 from all the reviews I have read.

    Without a doubt it is better, but don't know if it is up to par with DSLR yet. And the price, I bought for my whole DX kit for about what the EM-1 costs (D7000, 12-24 and 80-200 AF-S (I found some beater equipment, but it works). Is the EM-1 worth it? To me, yes it would be if I had the money, so that isn't the problem. My wallet is.

    But to keep on track, I am strictly asking about the D7100 since it has the crop mode, making it equivalent to m43. I haven't seen it discussed so I'm curious.

    Crop mode on the D7100 simply expands the centre portion of the image to full screen. It is equivalent ctopping in pp, so you could ask the same question of any APS-C or I suppose FF DSLR.

    While the C-AF on the E-M1 is better than the E-M5, personally I find the improvement pretty marginal. I havent used it that much and maybe it is really a question of faulty technique on my behalf. If you moved to the D7100 for its C-AF abilities I dont really see any pressing need to switch back to an OM-D. You would think that the 1.3x crop mode on the D7100 would give you pretty similar results to an E-M1, supposing, of course, that you are using lenses of a similar quality.

    I have a roundabout way for a conclusion.

    First though, the D7100 1.3X will produce an image 4800 x 3200 which complicates comparison to the OM-Ds 4608 x 3456.

    The D7100 produces a better image than the D7000 and very near in quality to the D800 when the D800 image is cropped.

    From similar shots between the OM-D and D800, the D800 produces a better image. Something that would probably show in a 16 x 20 print or maybe even an 11 x 14. Similar to the difference between the D7000 and a cropped D800 image.

    So my SWAG would be that the D7100 will produce a nicer image, but may take an 11 x 14 or larger print to clearly show the difference. A lot would depend on how the photo was cropped and any post production work.

    If you still have the EM-5 take a couple of comparison shots, and if I'm right, the IQ should be close
