I just received the Sigma 50mm f/1.4 DG HSM in Canon EF mount from LensRentals.com (this unit looks brand-new). I’m planning on comparing it to the Canon EF 50mm f/1.2L, EF 50/1.4, EF 50/1.8 and perhaps the Zeiss ZF 50/1.4. My findings will go into DAP, but I’ll likely share some images here in this blog as well.
Update: initial impressions are favorable, with some limitations in certain areas, details to follow in DAP.
And something very odd happens when using Canon’s Digital Photo Professional 18.104.22.168 to process files produced using the Sigma 50/1.4 and Lens Aberration Peripheral Illumination. Heck it might even be useful for some images! It only seems to affect images shot at f/1.4 and f/2.
