So if you buy the Sigma, make sure you unwrap it carefully, mount it carefully, and have no-hassle return privileges (so the retailer can sell the stinky copy to someone else?). But the Sigma's reputation for quality control, focus accuracy, etc. But if you really "need" 1.4, you'll have to settle for something less sharp and with more CA than the Makro Planar.įor another example, the Sigma 50/1.4 is definitely sharper than the Canon 1.4 wide open when using best examples of both. So you'll have to do some homework and decide what's important (center sharpness, corner sharpness, 1.4 vs 2.0, AF vs MF, willingness to keep buying and returning lenses until you get a good sample, etc.)įor example, the Zeiss 50/2 Makro Planar is sharper at f 2.0 than just about any other 50mm SLR lens is at f 2.0, regardless of the other lenses' maximum aperture (1.2, 1.4, etc.) and the M-P probably has less CA than any other fastish 50mm lens. Few companies do it as well as Leica in their M lenses, but those don't work on SLRs!īasically, there is no perfect solution, at any price, for an SLR. But it's extremely difficult to build one that's great (in terms of wide-open sharpness in the corners without much distortion). It's relatively easy to build a very good fast 50mm (in terms of wide-open sharpness at the center). There's the Nikon 50mm f1.4 AF-S G, which is sharper than the double Gauss derived Canon or older Nikon 50mm f1.4, but you can't really use a fast AF-S G effectively on an adapter (even that "twist the whole lens to stop down" adapter typically used for Nikon 14-24mm f2.8 zooms on Canon bodies).
