World's fastest zoom lens, the Sigma 18-35mm f/1.8 DC HSM Art is designed for APS-C sensor digital SLRs and has a large f/1.8 aperture for great depth-of-field control and low light shooting ability.

Excellent build and image quality


One needs to use this lens with care due to the shallow depth of field.

This is a classy lens for APS sensor cameras in every way. Build quality is first rate with smooth zoom and focusing action. It is a perfect match for my Canon 70D (or a 7D)
Image quality stopped down is razor sharp with virtually no distortion or vignetting. At F1.8 it is remarkable; a touch of vignetting an mild barreling at 18mm st close distances but compared to my 24-105 F4 L on my FF Canon the 70D Sig 18-35 combination; the IQ and bokeh on the Sig is far superior with a lot less distortion.
The bokeh helped by the 9 blade diaphragm
I compared the 70D 18-35 with my 5D Mk2 using the new Canon 24-70 F2.8. Taking the same shots wide open the sharpness. colour and bokeh of the Sigma was virtually identical to that of the $2000 Canon L series lens. I could not say at close inspection of the images which lens/camera was being used.
Because of the F1.8 aperture one needs to be careful with focusing at wide apertures and close range. For a head shot if you use the lens wide open; you will not have enough depth of field to keep your subject fully in focus. This is not a fault of the lens; but uses who upgrade from a kit lens will have to be very careful.
I use this lens for event photography, often in very low light conditions. it is good for video too as the zoom action is silky smooth and the silent a/f compliments the live view focus on the 70D very well. I have even tried it out on my Full Frame 5D mk 2. It works at 35mm with some vignetting; but the image circle is too small for shorter focal lengths.
After 6 months using this lens with my 70D; I have been highly impressed an can recommend this for those who want to get the best out of APS cameras like Canons 70D or Nikon's 7200.
