Preface I was looking to a wider addition to my TAMRON SP17-50/2.

Beautiful mechanics; Extremely low distortion

Very poor edge sharpness; Disaster corner sharpness; Vary poor performance against the light

Lens- specifications landscape or wide a screen sigma 8 -- 16 mm suitable for my needs very hobby , basically get photographed , detail and clean the shooting lens- sigma this . Mugnkin would be much better if diagframa can wider than a series of these . Overall excellent.

The Sigma 8-16mm F4.5-5.6 DS HSM ($1,100 list) is a lens that either speaks directly to your soul or you find nearly impossible to use effectively. It's available for Sigma, Canon, Nikon, Sony/Minolta, and Pentax APS-C cameras , where it produces a field of view equivalent to 12-24mm in classic 35mm...

Very, very wide; One-of-a-kind lens

Extreme distortion on the wide end; Relatively slow aperture; Softer at wide angles

This is an in-depth review of the Sigma 8-16mm f/4.5-f/5.6 DC HSM lens; the model tested had the Pentax-K mount.

A unique wide angle lens for APS-C cameras providing a rectilinear field of view equivalent to that of a 12-24mm lens on a 35mm camera.

Outstanding sharpness in the centre; Excellent build; Unique wide angle field of view for APS-C cameras; Compact dimensions; Silent focusing; Low distortion

CA towards edges of the frame at 8mm; Falloff at 8mm; No way to attach filters

Wide-angle lenses are essential for landscape photography, which is one of, if not the most popular, photographic genre. So when a brand new ultra wide-angle lens hits the shelves it's always going to be of interest to many of us.

This is my favourite lens without a shadow of a doubt. It's superb for landscapes and producing amazingly artistic photos from all manner of subjects. It's sharp as a knife and tough too.

I use it for almost everything. I love the depth of field. so far nothing I don't like about this lens

If you're in the market for a very wide angle zoom, this one is certainly worth considering.While there is distortion, that's to be expected with this type lens. The images it produces are, in a word, sharp.Its maximum f-stop tends to make shooting dim interiors difficult without a support

Consistent Output; Easily Interchangeable; Lightweight

Poor in Low Light

The Apple iPhone 14 is no match for the just-released iPhone 14 Pro, but if you ignore that, it’s one of the most effective phones around.

Great cameras, front and back, Fast performance, Good battery life, Innovative safety features

Design too familiar, Some average features
