Sigma 18-35mm F1.8 DC HSM | Art vs Sony E 18-200mm f/3.5-6.3 OSS LE

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.

Sadly I was not impressed. Detail was missing and contrast was low especially above 100mm, 200mm was sad to look at. Stoping down to f7 or f8 did not help. I was worried that maybe my expectations were too high for a zoom lens so as a comparison I got the selp18105g

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

Yes, it's a lot more expensive, but at least then I'll be getting a lens that can do a decent range, great image quality, and it can do double-duty on my still image camera AND the FS100 using the Metabones EF adapter.

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

If you're primarily a videographer, you'll want to think about the standard version or the Power Zoom variation, but photographers will be happy with the stabilization provided by the OSS LE.

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...

No frivolous comment, I bought a NEX for its light weight. It gets a bit soft at 200mm but, it is only a walk around $800 lens! Mind you, it is not terribly soft either. It has a great balance in my NEX 7. Color matches the camera and NO, it does not look cheap at all

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.

For one, it's large and heavy. In fact, it is as heavy if not slightly heavier than the camera body itself, meaning you will double the weight of the camera overall when using this lens. This is to be expected from a zoom lens with this focal length, but it's still something to mention. The other thing is that this lens definitely hunts for focus often

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

focussing is faster,and in video is smoother. Images are sharp across all focal lengths. Compared to the original Sony 18-200,certainly the image stabilization is much less effective in this one,only in video where I can notice my hands shaking even at 18mm,but for photos it works very well and focus is quicker
