"The new Sigma 50mm F1.4 DG HSM Art has been reengineered and redesigned to set a new standard of performance in the Art line"
Will this out performs my f1.2 L
For sharpness? Hell, the current 50 F/1.4 is sharper
after F/2 or so. Set a higher bar, will ya?
Again, for sharpness
, I think the new 50 from Sigma will dust the 50 1.2L based on the performance of the Sigma 35mm Art:
Consider Roger's take, which is a clear read:http://www.lensrentals.com/blog/2012/11/sigma-35mm-f1-4-arrives-announces-new-world-order
(Besides his nice article, note: "This lens kicks butt, takes names, and basically posterizes the manufacturers who make the cameras this lens will fit on.")
Then consider PhotoZone's take on both 35s and the 50 1.2L (poor away from center), which is attached. Those are stellar
F/1.4 and F/2 numbers away from center for the Sigma, by the way -- large aperture glass almost never shows such a good performance.
So I expect for sharpness the new Sigma to really take it to the 50 F/1.2L, but as everyone on this forum will say, there's more to it than that -- bokeh, distortion, chromatic effects, focus speed/accuracy/consistency, etc. may say that the Sigma is lacking in some department. We'll see.
Hell, off the cuff, size
may be a tipping point for some -- this lens had better cut diamonds
it's so sharp if it's going to take up 3-4x the volume in my bag as my trusty old Canon 50/1.4, and I don't expect the new Canon 50 F/?.? IS to be much bigger than its physical 'twin', the 35mm f/2 IS.
