Not really, this is a lens for cropped sensors and will reduce the resolution by about 40%. If you are searching Sigma lenses, make sure they have a DG designation instead of a DC designation.

The lens by itself is approximately 2.84 x 3.63 / 72.2 x 92.3 mm. The hood adds about 2.41 /61.21mm for a total of 5.24 /133.3mm.

Wider angle of view and better in low light performance

This has Limited 1-Year Warranty and Limited 3-Year U.S.A. Warranty Extension

Unfortunately, I ended up purchasing this lens to use with my IR-converted A6400 camera. The IR hotspots are HORRIBLE when using this lens!

Yes it will

I shoot the Sigma 16mm 1.4 in Sony E mount , which is made for crop sensor , on fullframe Sony A7S and A7Sii ... I can CHOOSE to shoot in crop 1.5 mode, then get equiv to 24mm, OR I can CHOOSE to shoot in full sensor , with some vignetting... or anything in between... I shoot mostly nightsky video with those cameras so some of the vignetting is eliminated because of the 16:9 ratio crop that comes automatically in video... and if you edit in letterbox 1:2.35 or similar you crop away even more of the vignetting... and if you shoot 4K you can even crop away most of the vignetting somewhere between 16 and 24 mm , and save in 1080p... and if you shoot the nightsky, northern lights like I do , well, haha, black vignetting around a black nightsky , no big deal ! ... not much of a problem, except there are not many stars in the vignetting black area.. or if you edit in 1:1 ratio ( e.g. for Instagram ) there's only tiny vignetting in corners.... in other words, this is a superb cheap 16mm 1.4 that can also be used on fullframe sensors, if you have a little bit of imagination and creativity. Ignore the rules, be free to do what you want. examples ? I don't know if I can share links here but you can find videos I shot of northern lights using the A7Sii and this Sigma 16mm 1.4 C lens. in youtube search : EPIC AURORA in SWEDEN HALLOWEEN 2021 or also : 3-day aurora hunt Iceland northern lights , used several cameras but the scenes of northern lights realtime video are all shot on A7S with this 16mm 1.4 , with or without crop. Or search my name in Instagram or FB aurorafiddler to see a few more examples. P.S. likewise, I shoot fullframe Canon EF lenses with speedbooster on full sensor, despite the "rules" ... sure I get again some vignetting, but meanwhile I speedboost my Sigma 20/1.4 to shoot at 14/1.0 ;-)

I'm not familiar with the Zeiss lens, but have been able to create some very satisfactory Panoramas with edge to edge sharpness. I'm quite pleased with the lens and would heartily recommend it to anyone.
