I use it with Sony A7R-III and Canon 17-40 L, Canon 70-200 f4 IS L, and Sigma 24-105 f4 lenses, and it works fine. Curiously, there is VERY slight rotational play (not visible but you can "feel" it) in the lens mount with the Sigma lens, probably within tolerances, but does not affect use or image...

Nice compact lens...bought this especially for the Grand Canyon trip. Served me well. A bit on the heavy side But with all that glass, it is inevitable. I guess we got to keep doing this until cell phones can surely replace DSLRs.

excellent product does exactly what it says it does, you will have to be aware that this will only work with certain Sigma lenses. build quality is top class. I bought it so that I could use it on my canon mount 150-600mm lens and it works wonderfully, all the Sony A7R ii feature work as with native...

For everyday shooting, a standard zoom lens is the go-to optic for most DSLR owners, so it pays to get a good one. The latest own-brand Canon and Nikon 24-70mm f/2.8 lenses have equally fast aperture ratings and are built to satisfy the most discerning professional photographers.

Sublime image quality; Excellent build quality; Great handling

Large 82mm filter thread; Typically heavy for an f/2.8 zoom; Not fully weather-sealed

After doing my research I an so glad that I got this lens. It is sharp wide open, focus is fast. The depth of field is great also.

This is my workhorse lens. I shoot with a lot of prime lenses and this is actually the only multi-focal lens that I own. Images come out super sharp. I use this more for landscape and architecture shots but I don't think it'll have any trouble doing portraits.

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

The Sigma 24-70mm F2.8 DG OS HSM Art is a new fast standard zoom lens for full-frame DSLR cameras. It will also work with APS-C sensors with an effective increase in focal length. The Sigma 24-70mm F2.8 DG OS HSM Art features a rounded 9 blade diaphragm which creates an attractive blur to the out of...

More like an iPhone 13S. The generational upgrades for the iPhone 14 are limited to a few subtle changes. At the same time, however, the base price climbs to 800 USD, while the only true innovation happens inside the iPhone 14 Pro series.

excellent OLED display, dust- and waterproof, fast Wi-Fi, wide range of supported frequencies, great camera, very fast performance, good battery life

display limited to 60 Hz, charging rate limited to 20 watts, no macro lens, wide notch
