Big O'l comparison thread 1650 vs 1855 vs sigma 30 NEX5N vs NEX6
Dec 23, 2012

hope this helps out those that are on the fence about getting the NEX-6 with the 1650

test parameters

tripod

steadyshot off

AWB

center focus

multimetering

2sec shutter delay

RAW

only processing in LR was CA correction and lens distoration

each comparison is done at the max aperture@that focal length and at F8

my conclusion is that the 1650 fails to impress in terms of center sharpness even when compared to the old 1855. However it does do much better corner to corner vs the 1855 especially when stopped down to F8, in fact cross the frame performance is almost on par with the sigma at F8. The sigma 30 is still king at all aperture. I did the top left extreme corner comparison against the 30 slight to the right so I can show how well the sigma resolves the wood and the screw, again the 1650 comes very close when at F8.

check out this gallery for center, and all 4 corner comparison of 1650 vs 1855

vs sigma 30



for those that say the 5n sensor is somehow sharper than the 6, here is the RAW from sigma 30 at F8

personally I think they look the same
