Customers say

Customers like the quality, size and weight of the lens. For example, they say it's a good mirror lens, it goes places they wouldn't take their larger lenses and it'll fit their A6000. That said, some complain about the focus and depth of field. Opinions are mixed on sharpness and ease of use.

13 customers mention0 positive13 negative

Customers are dissatisfied with the focus of the camera lens. They mention that it's not always easy, the focus doesn't turn quite as gently as they would like, and it can be hard to find the sweet focus spot. The lens is manual focus and has one aperture setting, 6.3. Customers also mention that the focus drifts a little and that the ring is very sensitive.

"...Close focusing can be difficult as the depth of field is very shallow, but for longer shots beyond 50yds (meters) it’s much easier...." Read more

"...See the sample of a succulent. Since the focus doesn't turn quite as gently as one might like, it can be hard to get the perfect plane on distant..." Read more

Tricky but useful, great for the price and size
If you are prepared for what you're getting, this is a cool lens. It won't make the sharpest images, it's very hard to use handheld, and it has a surprisingly thin depth of field - all of which means one has to focus very carefully and take a lot of shots to get one good one. At ten paces, if your subject moves even half a foot it'll be out of focus. But when you get it, maybe one shot in five, it works great. I still like the funny little donuts; if you don't like them, you have to be careful about background. Handheld, I've rarely gotten a good shot with longer exposure than 1/500th, but fortunately it has a big enough entrance pupil that one can do this (at least on the fuji x-t20) without pushing the ISO too high. It is surprisingly useful for macro (field of view on the X-T20 is maybe three inches at a meter away?) albeit with such a thin focal plane you have to actually want that effect. See the sample of a succulent. Since the focus doesn't turn quite as gently as one might like, it can be hard to get the perfect plane on distant shots, even using focus aids; it would be nice if the ring turned about twice as far as it does. The focus also drifts a little (maybe pressure inside?). And, it's annoying that it focuses beyond infinity... I'm not sure why this is the case, unless it's because they make different mounts for the lens and didn't bother realigning for each mount or something. So, three minor defects = minus one star, but even that feels a little bit mean, because it is awfully small and light and cheap for a lens so long. I've read that the Samyang/Rokinon build quality is inconsistent, but the one I got has no dust or smears or anything I can find wrong with it. All the samples accompanying this review are handheld on a Fuji X-T20.

5.0 out of 5 stars Love it. Long and sharp.
Reviewed in the United States on November 14, 2020
I love it. In th canon ef-m you may have to enable a setting in custom functions to allow the shutter to function without a detected lens. This is a 100% manual lens so the camera can't "see" it. Focus peaking works but the FOV is so short that it's hard to spot.

It is a crisp, sharp lens. Very long focal but compact, ofc. At this length I was still able to shoot some pretty low-light outdoors stuff at high ISO, handheld. I would need to use a tripod for any lower light tho. Still a great lens but at 300mm you need fairly high shutter speed (1/125+) to avoid any shake.

The attached photo is a scaled (reduced size) import from the camera, no post processing. Just JPG from the raw CR3. Great color, no visible abberation.

Lens comes with a hard plastic hood, which stores in place, is usable for the focus ring. Also ships with an OK lens bag and caps for both ends.

Compacto y ligero, increíble que tenga 300 mm de focal. Y la calidad de imagen en retrato y paisaje es muy buena (Canon EOS M6), eso sí siempre debe de utilizarse tripié para que la imagen sea nitida. Acepta filtros de 58mm. Apertura constante f/6
