Wild Light: 18??? Why not 35 or 50??????
whoa, the shootout shows a performance gap so huge that it almost suggests a bad copy. but then - if something like that passes the quality control, then it might really be a better idea to get the canon or sigma until there is a decent native E mount 35
The f1.4 stopped down to f1.8 is sharper :-)
Kwick1: And yet again, DPReview won't ask a direct question that's all over the forums and unanswered by Sigma: will the new 1.8 zooms work on the APS-H model? Of course pricing and availability is also a great unknown.
ok, so taking into account the physical size of the nikon fx and sigma aps-h sensors and sample images from nikon ff, the 18-35 will still present black corners when not stepped down at 18mm on the sigma.
rrccad - I didn't have time to crop out exactly the image circle of the APS-H of sigma. I know it is smaller than 1.2 crop. However, when I see at 1.2 that the image has big black parts (not darker - black), it shows that at 1.2 it still is way to small. Will it be better at 1.3 crop? Yes, but it still is not usable to me in most situations. Stopping down to f/8 a lens that you'd buy because of the constant f/1.8 aperture does not make sense to me. (of course, if you're a hobbyist and already have that lens in sigma mount - cool;). but as said - perhaps 50-100 will cover the whole aps-h image circle without need to crop. Remains to be seen. Have not looked at the primes from Sigma.@Kendall - yeah, sure. But cropping out anything out of such a great sensor is such a waste.
reviewed samples taken on nikon fx cameras with the 18-35 and even at 1.2 crop mode its not fully usable. especially at the wider end.might be better with the 50-100. Sigma should learn from the recent Pentax announcement and show a full list of compatible lenses. Perhaps some of the aps-c lenses of their offering would cover the image circle required by aps-h
ogl: Quattro H is compatible with Sigma FF lenses only
We might be surprised by this aps-h announcement, but Sigm itself surely isn't. If they have taken this into consideration when designing those excelent art lenses, this would be a hit
lesnapanda: Well, time for a new sigma DSLR with the sensor from dpX quadro series and fixed speed issues. Why otherwise make those sigma mount lenses at all?
Oh my! Mirrorless from Sigma!!! Goodbye savings!

He really claims this to be shot by a monkey? I really doubt it.

This is a plea to the lens geeks. Please do not start comparing the Canon lens with the Nikon one, it is pointless. The Nikon 200-400 does a great job for Nikon photographers and the Canon lens will do a great job for Canon photographers. Comparing the two is just pointless, as no one is going to change camera system to use this lens are they? No they are not, so please don’t fuel the silly Canon vs Nikon debate anymore, it’s not what this lens or this review is all about.
given the fact that you could buy the Nikon lens + D800E for less than the Canon - I'd say comparison is valid.
too bad I sold my nex... if it performs as good as the 30mm, it might be one of the best lenses for the system. For good light conditions though.
Antony John: Hmm, so how exactly does a lens 'gather light'?There's a little basket underneath or something?
Einstein was only one of many great minds of the 19th and 20th century whose work laid the foundation for understaning the dual nature of light (and other objects as well).
nawknai: This is like a rich guy suggesting that poor people just earn more money.
I grew up in the 'burbs.
I live in the city now, so I can try some street photography, but landscape photography is on hold until my next vacation.
If I'd buy a car, I couldn't afford a camera. Also don't have a driving license LOL ;) But when living in a city, there is a chance you can make "city-landscapes" kind of pictures. Of course - photos like those shown in the article are completely out of reach.
how strange this new lens... does not seem to be any improvement vs the sigma 19mm at around 3 times the price. It is smaller - yes. But the sigma is not big either, so why bother?
