I'm very happy with my current f/1.4 Sigma - but did anyone notice the maximum magnification ratio of 1:5.6? The MMR of the current model is only 1:7.4, something I stumble into when I do museums with this lens.
I used to own the 50mm f/1.4 and used it on a 550D and 7D. Great lens for museums.
Africa Museum - very little light inside
550D iso3200 and f1.4(of course) - there is some noise here
It's a fabulous lens for this application; only the small displays could use a little more magnification though (on full frame) but I don't consider 1:5.6 vs 1:7.4 max magnification to be enough of a difference to justify getting the new Sigma for this feature only
I visited a museum for ethnic sciences, they have some African stuff too
Sample below: Canon EOS 5D Mark II ,1/50 sec, f/2.8 iso 2000, -0,67 EV
I must admit, I did not like the sigma 50 on my 5d MKIII. I sold it but I am awaiting the new sigma. First I would like to see some reviews with field examples using a FF camera
What didn't you like, specifically? I'm actually having even more fun with this lens on the MkIII than on the MkII although it's harder to check critical sharpness on the Mk III at wide apertures (my Mk II has a precision matte focusing screen). On the Mk II I use manual override to tweak the sharpness at wide apertures, on the Mk III I've set AFMA +8 for this lens.
Of course it is a personal opinion based on the combination of my camera and the specific lens but I found it less sharp it the center and especially corners (though I did run Focal to set AFMA)
Considering the praise on the Sigma 35mm I have high expectation of the Sigma 50mm f/1.4 Art
I truly hope the price will be more in the 600 euro range rather than 800 to 900. The current 50mm of Sigma is around 440 euro. The 35mm Art went down to around 730 euro.
