Great quality lens for the price, fantastic for use as a wide-angle lens with a crop-sensor camera.

Great lens for the price

The product was great, worked as it should’ve and is a good and sharp lens for the price. Would recommend again

Rokinon 10mm lens for Sony e mount

I needed a super wide, bright lens for timed exposure Aurora Borealis shots. This worked perfectly. I finally can quit saying...
I need a wider lens.

Used it for Aurora shots

Great lens, heavy, clear, manual focus, Astro magic

Wilderness of stars

This Lens just returned from Egypt!  It worked perfectly with my only two minor comments:  I wish it were capable of closer focus, and it is a bit tight mounting.  I expect the second issue will eventually sort itself out.  This is more useful than the Nikon wide angle I also have.  Thanks for the recommendation, I like this lens a lot.

I like this lens very much

I can definitely say that this is a great lens. The pictures are sharp and the ultra wide angle capability is awesome. It is certainly a great lens for the money. However, I do wish the lens has the capability to talk to the camera simply to let me know what the aperture was along with recording the shutter speed. For this lens I do not need autofocus (although that would be nice) as it has such a wide depth of field. I simply would like to know what the parameters were of the picture I took.

Great Lens - Wish it Talked to the Camera

I got this lens with the main objective of astrophotography. All the initial tests shows that is very capable of such duties. 
The Milky Way looks gorgeous! This is a fast, sharp and well built lens. Loving it!

Met and exceeded my expectations

Not a bad lens for the money, but it is a little soft on the edges. Works ok for Real Estate MLS interiour shots.

It's good for the money. You get what you pay for.

Just purchased this lens last month for a night sky photo workshop. Had great results. Am very pleased with the quality of the optics as well as the general fit and finish of the lens.

Rokinon 10mm f2.8

This is a beautiful lens, wonderful if you want a very wide lens for something that does not require fast focusing, as this is a manual lens, gives you beautiful images, well worth the price.

Beautiful Cinematic Feel Lens

I recently have combined my photography and astronomy hobbies. I have been doing deep sky astrophotography with my telescopes but also wanted to do some wide field night sky photography. I had previously purchased a Rokinon 16 MM lens which I use for piggyback photography on top of a telescope on an equatorial mount. I wanted a lens that I could mount on a simple tripod and get 30 second exposures without star trailing. The Rokinon 10MM lens is exactly what I have been looking for. At F2.8 it is fast enough and the 10MM focal length allows me to take the 30 second exposures that I was looking for. It is easy to focus and has a nice feel to the focus. The images are sharp and the lens construction appears to be very good. I am very pleased with my purchase.

Great for night sky photography

Although  it's manual focus, if your using it as a landscape lens take the time to get exact focus because this lens is extremely sharp.. Not recommended for full frame cameras because of bad vignetting.  Love it on the 7D2 though
