Reader Inquiry: Sigma DG HSM Art Lenses on Canon 5DS R

Get Sigma 24mm f/1.4 DG HSM Art and Sigma 35mm f/1.4 DG HSM Art and Sigma DG 50mm f/1.4 DG HSM Art at B&H Photo.

Any plans of testing the Sigma Art series lenses namely, 24mm, 35mm, 50mm f1.4 DG HSM Art on the Canon 5DS R?

I have purchased these three (price driven,unfortunately) based on your positive field testing with them. Am wondering how they will stand up to a sensor in the 40-50 mpixel in anticipation of Nikons next high res. DSLR.

Thank you for your detailed "in field,real world" testing and recommendations. Its the only site worth taking notice of. Appreciate your hard work.

DIGLLOYD: I just literally put the Sigma 24mm f/1.4 DG HSM Art and Sigma 50mm f/1.4 DG HSM Art in my photo backpack for departure tomorrow for several days of field work in Yosemite. With rain in the Sierra, most forest fires are almost dead out, so the air and conditions should be ideal, unlike my late June trip, where I was smoked home.

I am a big fan of the outstanding value offered by the Sigma Art line, including the superb lens case shipped with the Sigma Art lenses, which makes a laughingstock of the cheapo Canon and Nikon soft pouches. Superb because the Sigma case protect the lenses and pack well. I like them enough that I really wish Zeiss would do something similar as I always need to jam a bunch of stuff into my North Face Recon daypack and that means some kind of protective case (jostling issues and similar). So the Zeiss lenses go into neoprene style pouches, a bit more compact and a bit tight with some. I end up preferring the Sigma cases. Nor does Sigma skimp on lens hoods—included with all the Art lenses.

I am also revisiting the Canon 8-15mm f/4L and the Canon 11-24mm f/4L zooms. These lenses are excellent but I want to see their limits on the Canon 5DS R. The 24-70mm f/2.8L II is very good too but my sample is decentered and is at Canon for adjustment.

I’ll take the Leica Q along as a hiking camera (and the much more useful Ricoh GR with its built-in flash for happy snaps), to see if I can un-bore myself with it while climbing some peaks. I wanted a corner to corner whacko-sharp lens, but the 28/1.7 Summilux on it lens is a disappointment, not to mention closer in speed to a Summicron than a Summilux, cheating on the Summilux moniker in both speed and performance.
