The Sigma 35mm f/1.4 DG HSM shows itself to be an outstanding lens. At about $899, it represents a terrific value.
But the 35/1.4 doesn’t need the price to compete— it can do that based on its performance. Surely this is one of Sigma’s very best lenses. Particularly of practical use is its high micro contrast at f/1.4, which makes focusing relatively easy in magnified Live View mode, and also discourages contrast-detect autofocus from making errors. As well as delivering persuasive results wide open.
As I found out today, its lens shade is effective in keeping light rain off the front element even as the body of the lens became covered with water droplets. The build quality seems quite good, but of course only extended use can prove out a design.
I don’t yet have a Nikon-mount version, so I cannot yet compare it to Nikon’s 35mm f/1.4G, but I plan to do so (and eventually to the two Zeiss 35mm lenses, in Guide to Zeiss).
