Rokinon 12mm f/2.0 NCS CS vs Sigma 18-35mm F1.8 DC HSM | Art

For landscapes, especially including night skyscapes, another budget option is the Rokinon 12mm f/2. I haven't tried the new autofocus version, but the manual version is a popular lens for good reason and is great value. (I don't think I would pay $500 for the autofocus version one.)

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.

It's like, if you own a Sony or Canon APS-C camera and you don't own this lens, what are you doing? Even if you'd rather have a 28mm or 35mm equivalent, just get this lens and crop it because it's going to look better anyway. And if you are shooting video, just enable Clear Image Zoom and all your wide angle needs are taken care of in one lens.

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

However, it seems that Rokinon has poor quality control resulting in some lenses in the market that are not meeting the expectation of high optical quality. If you get a good copy, I highly recommend this lens. The first one I purchased felt like the infinity stop on the focus ring was not quite at the right location, resulting in shots that were passable but not quite sharp enough. I got it replaced for free through Amazon in two days

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

(I'm very much a novice photographer, so the interchangeable lens, point and shoot, autofocus aspect isn't objectionable, to me.) Nighttime astrophotography shouldn't be a problem, with focus set to infinity, wide open apertures, and tripod shooting. I may keep it, just for this use, we'll see. EDIT: Well, I decided to keep the lens

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

So far I’m impressed with the weight although not quite like a pancake lens it’s built solid. I put it on my Sony a6100. The manual focus is going to take getting use to. I normally shoot with a canon 6D and either a sigma 35 art or 24-70 L lens

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...

The larger apertures still yield sharp images. My lens focuses at infinity very close to the markings on the lens barrel, with only a tad of over-focus (necessary for me to dial in the focus precisely). I have been using this on a Sony a6000 and have been extremely pleased--just note that you have to set the camera mode to M rather than S to access the Bulb setting for time exposures. Otherwise, you can set to S and select a shutter speed to match your manual setting of focus and aperture

If you shoot mostly at a wide angle setting, and you're craving for more aperture, this lens is for you. Even more so if you're a crop-sensor person (this lens is crop-sensor specific) and you're not planning to go full-frame anytime soon. Also consider some possible inconveniences of the lens before purchasing it, like the fact that is not small, and is not lightweight.
