Sigma VS Canon

[supersonic]

(For Canon users)

With a Full Frame camera, i am wondering which ultra wide zoom lens to purchase. So i really need feedbacks on Sigma and Canon lens in terms of ultra wide angle only

Sigma 12-24mm F4.5-5.6 EX DG Aspherical HSM
Canon 16-35mm F2.8L USM

Really quite straighforward.

For the widest possible, go for the Sigma. Of course, you lose the fast f/stop, and you can't mount front-mounted filters.

If your priority is low light, go for the 16-35. It depends on what you shoot really.

If you are shooting landscape primarily, then a good balance would be a 17-40L, as this is sharper than the 16-35 f/2.8, especially in the corners, and cheaper too.

FF you say? Canon 16-35mm F2.8L USM is wider than Sigma 12-24mm F4.5-5.6 EX DG Aspherical HSM.

DG on Sigma lenses denotes Digital Only, meaning APS-C or cropped sensor.

The Sigma 12-24 is a Full-Frame lens. Its the widest rectilinear autofocus lens available in the market.

'DC' is what is denoted for 'Digital Cropped'. 'DG' means its FF.

You got it wrong.

DC is for Digital Only, DG means the lens coatings are optimised for Digital, but it can be used on film or full frame, as well as 1.3x crop and 1.6x crop.
