This lens was right out of the box and onto my camera. I found the focus to be tack sharp without any tuning and all focal lengths tested. Great color and contrast. Focus was fast and quiet. The constant length, and non-rotating lens is a plus for me.

I am on the fence to return this item. .. I was looking for a good travel lens that could cover good street and portrait focal lengths with low light capability . Description says designed for Aps-c. 50-100mm f1.8 from sigma... This sounded great. ..

I am still on the fence for this lens. It might be because I love my 28-35 1.8 so much that I need to give it a chance

Sharp; fast; build quality; much better than the 24-105

Now this is a heavy lens, tripod foot but I learned to live with it, hoped it would be as great as my 18-35 1.8 but no not quite; Did I mention heavy No OS

This lens looks and feels quality. Be warned its is a bit of a monster, and is a heavy weight. The image is sharp and beautiful. I have two Sigma art lenses (I also have the 18-35) now and opted for these as they are billed as professional quality glass for aps-c cameras.

First quick impressions: - very sharp at 1.8 - very smooth and creamy bokeh - extremely high build quality...the zoom ring smoothness is otherworldly - i have not experienced any focus issues so far...auto-focus is fast and silent..

While it's a shame that picture and sound quality haven't been upgraded, the iPhone 13 was great in these regards and the iPhone 14 is, too Excellent display Admirable headphone performance Solid build quality No upgrades to picture or sound Familiar design Notch is still present

Apple's latest non-Pro iPhone is superb - it's just that it's strikingly similar to last year's effort.

Still an incredible smartphone, Brilliant battery life gets a bit better, Excellent camera system gets a bit better

Last year’s Pro hardware, Wireless charging slow by modern standards, No USB-C; it’s now well overdue

Is the Sigma 50-100mm f/1.8 DC HSM A as good as the first APS-C zoom lens with a maximum aperture of f/1.8? Michael Topham finds out

The Sigma 50-100mm F/1.8 DC HSM Art is an interesting proposition. It's almost like three or four prime lenses in one (50mm, 60mm 85mm and 100mm), but with the added bonus of offering a wide f/1.8 aperture - something which you won't find in 100mm prime lenses.

Not content with just the one optic in the Global Vision Art series of fast-aperture lenses, Sigma's engineers have burnt the midnight oil and produced their second f/1.8 zoom, which was showcased for the first time at the CP+ show in Japan earlier this year.
