Some time ago I was sent a pre-production unit of the 17-70mm F2.8-4 DC Macro OS HSM lens made by Sigma. It has been out for some time for other cameras such as Canon and Nikon but my version was of course made for Sigmas SA mount. It was a pre-production unit and I couldn’t really utilize the full OS capability as it wasn’t yet optimized but I did get some real stunner from it with OS and even more so without. Some shots below has had the OS enabled and they appear less sharp in full view, I’m told this will not be the case with the final version.
Those of you that used the older 17-70 will most likely enjoy this new version as well as it’s now more of an EX lens although no EX branding on it. The build quality is very high and it’s bit heavy and feels very solid. It’s like a bigger brother to the current 18-50 2.8 EX – same materials but a bit longer and fatter. Both lenses can produce stunning captures.
The quality produced by this lens is quite extraorinary, to be a none EX lens and a zoom.
Full size version (look at his chest!, that’s where focus is)
Final verdict will as you might understand comes later when I have the “real deal” to play with but what’s seen so far is pretty amazing. Good stuff! Just take a look at this last picture of the trees, detail is not bad and I’m told that it might give up to four full stops of stability. I did get some 1/10s shots that I might show later using ISo3200 (very dark environment) and they looked very nice! :) Me like.
