I had a 11/16 mm on my D7100 and when I went to the D800E, I looked for a super zoom lens, except that it is hyper prices among manufacturers Nikon, Canon and so on .. .
I had heard of Samyang but return to the hand coffee grinder leaving the power, nowadays it's rare.
Well it is the same impression through the lens stabilized with fast AF. There, over the former objective (but how difficult to distinguish visually between the old 14 mm which is completely manual (aperture and focus) and the latter model has a chip that talks to the case. It therefore only remains to be developed.
However, if you set your aperture f8, the focus is valid one meter to infinity and you have little chance to blurry pictures.
Fun, it reminds me of my updates on my first reflex: a Russian zenith !!!
However, this goal is "reassuring", it balances well the case, even if all without the grip almost 2 kg to wear.
Next shot, I started upon receipt by photos poses night (30 seconds f8) ... the result is breathtaking. Test results include Sharpness is better than Nikon in the same focal / opening and it costs 3-4 times cheaper than the alternatives of the brand.
I give a exceptionne 9/10 and would recommend to any good amateur who wants to make photos at a large field, knowing that with the product DxO viewpoint2, we can straighten all perspectives provided good enroll about halfway up format as straightening, buildings quickly touch the "ceiling" of the possibilities ...
Note 9/10 - very highly recommended to purchase
