Even though box said Olympus. The lens came with a Nikon mount. Since I do not have a Nikon lens, this product is completely useless to me. I just wasted Money!

I purchased this lens for portraits. I have a cannon 20D with a cropped sensor so I knew I would lose frame space. No big deal for portraits. Big deal for landscape shots though. Regardless, it was an incredible improvement. So much for saving up $1,700 for the Canon version. I'm good.

Beautiful images and usability for a wonderful price! Never been happier. I use it with my Canon EOS 6D and am in love with the whole set up.

Camera: T3i (2012) 6000+ shots (according to magic lantern) Lens: almost a year old Why am i calling this a gem in a rough, well i believe now-a-days most low to pro-grade lenses have auto confirmation and auto-focus motors/ultra-sonic motor (USM), but this doesn't! Should you worry?

This is an amazing lens. I love everything about it for filming video with a DSLR camera. I do not recommend this lens for still photos - it's manual focus and it's incredibly difficult to get a good image in focus.

I have a bunch of Rokinon Lenses. They are a great alternative to Canon L. They are solid lenses for the money and they take great images. I recommend them to people all the time. If you are on a budget and you cannot afford Canon L or Zeiss glass, get rokinon. No issues here.

I love this lens, the glass is so sharp - it makes you think while using it, and it's focus is buttery soft... Sharpest lens I own and hasn't left my 60D since it came in.

I use this one a lot with my Sony FS-700. Combined with my Metabones Speedbooster I'm at about 1.2 and the depth of field is amazing shallow!

I have had this lens for a little over a week. I have used it 4 times. I have gotten some of the sharpest images that I have ever gotten with it. I use it with a Canon T2i and there are some issues using it with live view in manual mode on my camera.

If you can shoot manual, you will love this lens. Possibilities are great many! I have been thrilled with the results.
