Pros: Very sharp, metal building exceptional, compact, fast autofocus although it uses the old scheme arc.
Cons: Chromatic aberration rather high, ghosting, vignetting at F 2.8 out of full frame.rndistorsione evident at 20 mm.rnNon there are replacement parts, so that, once you break something, you stick to the tram ...
Opinion: I own this lens for a month, but, however small it is my technique, I can say I have pointed out quite clearly the merits and difetti.rnLo use on full frame Canon 6d. In a review of Pine DiCaprio is considered lower than both the 17-35 f2, 8 that the 16-35 f2, 8. But we are talking about a review of the 2004.rnNonostante this, I decided to buy it and found it to 400 euro .. The specimen shows signs of wear, but better than I expected, given that, at a minimum, 18 years old on spalle.rnConfrontato with the 17/40 F4 I have, I must say that at the level of contrast and sharpness you do not notice the differenza.Anzi, from F4 onwards it is also a bit more detail. rnAutofocus fast, although it is not ultrasonic. It 'sa bit noisy, but it sounds to me piace.rnDa a feeling of enormous strength when you pick it up, being all metal. rnPurtroppo, using Photoshop DC, does not appear among the objectives for which it is provided for the correction of chromatic aberration and distorsione.rnLa sore point is its aberration chromeica that appears when you take pictures in notturna.Il 17-40 suffers much less, but God forbid ... rnPiuttosto visible vignetting at F2, 8 on full frame, the rest fairly correctable in post - ghost in produzione.rnEffetto backlight. compared with the 17-40, the latter widely winner emerges. rn |
