Summary: I have been using this lens since I got it. I even Shot a wedding with it soon after I got it June 10. Excellent, Excellent, Excellent. However, the only down side is the manual focal. Needs to be Auto in times like wedding shooting when you need to be quick on the action, the overall circumference could be a bit meatier and a shorter minimum focal length would make it a far Superior lens. But all in all. great lens for the price. Well done.
Excerpt: Would you sacrifice autofocus for exceptional image quality? The Samyang 85mm f1.4 is a fully manual lens, with internal optics that rival much more expensive lenses such as Canons own 85mm 1.2, which will set you back around 1800 dollars. The Samyang 85mm f1.4 is sharp wide open, though it's sweet spot is somewhere around f2.8. Vignetting is obvious around 1.4, and all but disappears from around f2. Bokeh is pleasing.
Pros: Built quality, Image quality, Bang for buck, Smooth focus ring.
Cons: The lack of autofocus will be a big deal for some people.
Summary: this is my 3rd favourite samyang lens after 35mm f1.4 and 24mm f1.4. obviously samyang is not for those who are not comfortable with manual focusing but for my it works great. most of the time i don't use them wide open for sharpness and larger depth of field makes it easy to do focus manually.
Pros: Contrasty, Durable, Great Picture Quality, Sharp
