Does anybody have any experience or information about lenses that are good for this purpose? The problem is sites like DxO don't test for coma so I thought I would ask the collective. The lens I am looking for has to be 1.4 or 1.8 and be usable at that aperture as light down the lens is king. Focal length must be from 14 to 24mm.
I have bought the Samyang 14mm f2.8 and the 24mm f1.4 because they were recommended as 'no coma' whereas in fact they were 'low' coma. @Ironheart kindly took a shot with his new 20 f1.8 which was better for coma than either of the Samyangs, but still has a little - it is most likely to be the lens I purchase so far.
This is an unusual situation in that when one asks for quality people always say 'Zeiss' but I have found Zeiss to be only average in this regard. Please don't take excellent IQ in any other regard as an indication of merit for coma, it isn't so. The easiest test is a shot of the stars wide open and then check the corners for flying doves.
I have read that the 14-24 is good but the problem is only f2.8 max aperture. The person recommending it is a blogger who uses a really basic workflow and only does small images on-line so has little credibility. Does anybody here know how it does for coma specifically?
