Sigma 18-35mm F1.8 DC HSM | Art vs Sony E 20mm f/2.8

8 improves the overall score to 2,423 lines with edge performance just shy of 1,900 lines. Resolution at its widest focal length peaks at f/4; the lens manages 2,377 lines there.

Kind of ruins the lenses small size, but then again, what else would you expect? and the Lands also has a forty nine millimeter filter thread for very...

8 the lens scores 2,470 lines, and it peaks at f/4 at 2,690 lines. At 28mm the lens manages 2,457 lines at f/1.8 and improves to 2,562 lines by f/4. Zooming all the way in to 35mm delivers 2,399 lines at f/1

8 the Sony 20 at least gives you the added bonus of not having that terrible magnetic AF system that makes your frame pulsate like the veins on your g...

In the end, if you're thinking about getting this lens, the only question on your mind should be "is 35mm long enough for me?" As far as anything else in the equation, Sigma has you covered better than anyone else. If 35mm is long enough, there's no reason to hold off on this lens. If not, go out and get this lens and a 50mm prime! ;) PS: I'd HIGHLY recommend getting the Sigma USB Dock with this lens, at only $60 extra. All zooms are known to be a bit off on focus on one end or the other to varying extents

compared to a good prime lens such as the 35mm f/1.8 (which is small too and has image stabilization) or the Sigma 19mm f/2.8 which is compact and costs around $150 less, the pictures I took with this Sony pancake are muddy, too soft, simply not sharp. Would not recommend

Heavy. This lens is quite heavy at 810 grams. Of course cinema lenses for example are much heavier but this lens is also aimed at people shooting with...

An okay lens if size and weight is your main criteria. I hoped this would be an excellent video lens but, alas, it was not to be. After using for a couple of weeks, I agree with many that this is an okay, not exemplary, Sony offering.

The build quality is also excellent, feeling very solid and well-constructed. The only downside is that it is a bit on the heavy side, but that is to be expected with a lens of this caliber. The biggest negative (for me at least) is that it's SUPER LARGE.

I would give it four stars for size alone, but image quality just isn't that spectacular (three stars) -- not really much better than the 16mm pancake I already have. Unless you REALLY REALLY want a pancake, you would be better off with the 19mm Sigma f/2.8 at $200.Not to mention the fact that the Sigma comes with a very nice case and sun visor (the Sony comes with nothing)

6x crop factor). That's still a good focal range for landscape and portrait photography, but too short to use at something like a concert or for sports. The autofocus is super smooth and very quite, but the focus is a little slow compared to my Canon 17-55mm f/2.8

You're not going to use this lens for really fast moments since the autofocus can't keep up - at least on the a6400. Works well enough for casual, moderate pace street scenes or kids. Picture quality is decent center of frame, but off-center it is soft wide open. Stopped down it is mostly okay
