Took delivery of my Samyang 14mm 2.8, a manual focus lens with EOS mount. I have actually ended up with two of these by accident. but anyway, if you are not familiar with the lens, worth looking at photozone evaluation of it. http://www.photozone.de/canon_eos_ff/532-samyang14f28eosff
I am waiting for my focus confirmation chip from ebay, mainly to program the focal length in to show on exif. I already have an acr profile for correcting distotion.
So far very happy. CA is nearly non existent, and its a very sharp lens. Here is my favorite spot. http://farm5.static.flickr.com/4106/4839570291_8b8f733c5a_b.jpg
this is shot. on 5d2, f 5.6, iso 100, 3 shot composite. the lens is know for having a mustache and fair degree of barrel distortion, which needs correction in architectural shooting. In landscape it just does not show, but I have an acr profile to correct it, and ptlens also corrects it. the reason I got the focus confirmation ship, is that I can now dial in the exif (aperture, focal length) . right now it shows 00 for aperture, and 50 for focal lenght. the aperture is also by a manual ring, which does not bother me at all.
it does seem like a very impressive lens, it could even be had on ebay with cashback for $356 delivered! for some reason i passed it by.... mostly didn't want to spend more now, but man that would've be some lens for some price.
Love the color and clarity. I'm just starting off on landscapes, so I can't offer any helpful critique. But these are the kinds of shots that tell me what I should be strivng for -
