I bought this lens as an experiment for an architecture assignment, I wanted to include some extra "spicy" images in the portfolio. I quickly found out that I could use it for almost ANY subject. It is far more versatile that I imagined!!

Extremely sharp and contrasty; quick HSM-focus; solid build; very LOW distortion; hardly any chromatic aberrations

the extreme corners of the image are soft and distorted, but it improves dramatically when stopped down; vulnerable to flare

For its type, the Sigma 12-24mm f/4 DG HSM Art lens is a good performer and buyers should be satisfied with the results they can obtain with it, provided they are aware of its capabilities and limitations. It's also a lot of fun to use.

The Sigma 12-24mm F4 DG HSM Art is a new ultra-wide-angle zoom lens for full-frame and APS-C DSLR cameras. It offers the equivalent angle of view as an 18-36 mm lens on an APS-C system (depending on the crop factor).

This is a brand new lens in the Sigma line-up and dPS had a chance to try it out. See...

This is the ugliest imaginable lens... Sorry, but had to say that and get it off my chest. It just looks ghastly on my Nikon F5 and on the F100 too. Oh, well, now that I said it, I should add that it's a very good, reliable tool. Where does one get a wide-angle this wide Nowhere!

Speed, size and relatively discreet look (if it wasn't for that front element that's downright bulbous); Nice range of focal lengths

Maybe it's ugliness, along with that the front element is so weird looking and doesn't allow for filters of any type; Other than that, it's not a lens to use with flash 'cuz it vignettes like mad, especially at 12mm (and what's the fun of using a flash at 24mm with this lens None.

I have owned this lens for about nine months now and have used it for both bird and mammal photography. I sold the Nikon 500mm f4 that I previously owned and after much research, eventually bought this one. I was much influenced by the superb testing of this lens by Canadian photographer Brad Hill.

Durable; Great Features; Great Picture Quality

Bulky; Heavy

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

If you're into high quality glass, this is the kind of lens you can get lost in. Build quality is exceptional, performance is outstanding and…I'm getting ahead of myself, but you'll see the world in a whole new way when you use this lens.

This ultra-wide angle zoom lens from Sigma projects an image circle big enough for full frame digital/35mm and is still very wide on a cropped sensor. We take a look at how it performs.

Enormous field of view; Amazing control of distortions; Solid build quality with good protection of front element

Difficult to use front mounted filters (Though not impossible; Bulbous front element needs careful handling
