One of the best wide angle primes at a bargain price.I
By K. Dardashti
I am using this lens on a Canon 5D Mark II. I have several zoom lenses in this range, but was looking for a fast, superwide prime. The choice would be this or the Canon 14L II. This is the same as the Samyang, rebranded.After receiving the lens, I ran some tests against 16-35 2.8, and sigma 12-24, and was floored. The corner to corner sharpness of this lens is fantastic. I peaks at around 5.6, but the corners at 2.8 are better than the other 2 lenses at f11. the microcontrast and color is very good. The barrel distortion is hefty, and complex with a mustache distortion, however, often not well visible in landscape, but visible in architectural images. It is correctable using a $25 program called ptlens, and there is also a profile for acr 6.1 out there, which works great. It is an absolute bargain. I purchased a focus confirmation chip for 14 from ebay, glued it on, and I get focus confirmation too.feb 2012 updateI have had this lens along side Nikon 14-24 2.8, adapted to canon with use on my 5d2, and at 2.8, the rokinon is sharper in the corners has less flare and less CA than the mighty Nikon. However the nikon has less distortion, and catches up by f 5.6 even in the corners. Additionally, do not rely on the distance markings on the focus ring. On my copy infinity focus is achieved at the 3 meter marking. 3 meters is achieved at 2m. for my style of shooting I dont find this troublesome at all. for landscape shooting I focus with live view anyway. for hand held, my focus is between 1 and 2 meters most of the time and it works fine.

Sharpest lens I ever used, but check for issues
By J. Kim
This is the new version with the auto-exposure chip (only for Nikon mount) and UMC coating. My impressions:Pros:-Sharp, sharp, sharp. Even at f/2.8, this lens is sharp. At its sharpest aperture, f/5.6, it's sharp corner-to-corner on an APS-C camera.-Very good build quality. Solid weighty feel, brass mount, and smooth dampened focus ring.-By far the least expensive 14mm around.-No problems with auto-exposure or focus confirmation (including the electronic rangefinder function on newer Nikon bodies)-FX or DXCons:-Cheap rear cap fits a little loose. I swapped mine with a Nikon cap.-Has significant mustache-type barrel distortion in the middle of the frame. Not a lens for architectural photography. However, this can be mostly corrected in post-processing (with the $25 software PTLens, or user-created Lightroom profiles on the net).Some considerations:-Like some other ultra wide-angle lenses, the front element is large and bulbous, and the hood is integrated and non-removable. You can't attach any filters, so this lens requires more care to avoid scratches on the front element. The lens cover should be kept on at all times when not in use.-Although the lens works great with my DX camera, it's really meant for FX cameras. On my DX Nikon the full-frame equivalent focal length is 21mm, which sits in an odd space between UWA and WA. DX users should probably consider the Tokina 11-16mm f/2.8 or Sigma 10-20mm instead for their UWA needs. However, this lens beats both for corner-to-corner sharpness.UPDATE:I sold my Nikon AE copy and re-purchased this lens for Canon mount, for a Canon 5D body. My new copy was just as sharp as my previous copy in the center. However the lens showed de-centering on the right side, which was significantly blurrier than the left even when stopped down to f/8 or f/11. This area would not be visible on an APS-C body, but was visible enough on the 5D that I returned it for a refund. I deducted one star from my rating until I can test another copy.

Multiple copies before a good one
By D. Dietiker
I bought this lens after reading reviews about how Sharp it was. The distortion issue didn't bother me as it rarely shows in a landscape photograph which is all I do. I went through 3 copies to find a good one. The first was just plain soft all over. Since it is a manual focus I thought maybe I'm not getting it right, never mind I manual focus with my other lenses most of the time. No matter what I tried, the first was soft. I returned it and received another, the second was significantly decentered. The center and right side were very sharp, the left side was total mush, sent that one back too. The third copy I received finally lived up to what I had read about this lens. I will be keeping this one.If I had received the last copy first, I would have given this lens 5 stars.If you do order the lens, make sure you test it vigorously, as the quality control to me is very suspect. If you dont test your lenses, I would pass on this one.
