Sigma 20mm f/1.8 EX DG Aspherical RF review by micahmedia

 

Ain't nothin else like it. Literally it's own class. Nothing that's simultaneously as wide and as fast.

nothing else like it, wide, fast, close focus

big, janky focus selection

A bit disappointed.

 

I\'m a bit disappointed with the sharpness of this lens. I compared it to a cheap Canon zoom lens (18-200 3.5-5.6 IS): the same scene, on a tripod, with IS turned off on the Canon lens, with the same settings. Sigma is unfortunately a lot softer than...

hood and case included in the price","small barrel distortion as for this wide lens","there\'s no canon lens this wide with f\/1.8

random autofocus","soft especially wide open

Sigma 20mm f/1.8 EX DG Aspherical RF review by Lee Jay

 

A little soft wide open, but certainly usable. I sold it because the focusing was just terrible in low light.

Pretty good optically, pretty nice FL on 1.6 crop or FF

Slow focusing, wierd mechanism

Sigma 20mm f/1.8 EX DG Aspherical RF review by gadgetguy

 

If you want WIDE and FAST, well, there simpy is no other way to go. IQ is not bad, considering price and the technological breakthroughs (and compromises) for this lens.

20mm and f1.8 - simply no competition

slow AF

Sigma 20mm f/1.8 EX DG Aspherical RF review by NikonEddy

 

Bought purely because its possibly the fastest 20mm available. Its a delight to use. I have used it wide open with no real problems, possibly a little soft on a Film camera (Nikon F4s) but thats to be expected. The lens comes with a sturdy pouch...

Focal Length, Wide aperture

bulky, filter size

Sigma 20mm f/1.8 EX DG Aspherical RF review by fstopjojo

 

Sigma has a good lens here to which Canon really has no answer for. My biggest gripe is the overall "handling" of this 20mm beast with its somewhat large build and clunky "DF" focus mechanism. But all in all, the pros far outweigh the cons and the...

Great price for 20mm wide and f1.8 speed, FF compatible, Very sharp from f2.5 (good wide open), Very good contrast, 8" minimum focusing distance a boon, Grippy and wide MF ring with solid stops at each limit, Feels like a tank

No HSM, AF speed and noise are "okay", Dual-Focus clutch mechanism takes getting used to, Some may not like the 82mm size thread and overall bulk of lens, Shadow cast with hood on and internal flash (no problems with hood off or external flash)
