Summary: Excellent lens.Great for using with fireworks and doing Panoramas.I am amazed at the field of vision and how sharp and crisp the photos were. This lens goes with my travelling kit. Looking forward to using on my next trip overseas.
Summary: Love, Love, Love this lens! This is my 3rd Version II of this lens .... nothing wrong with the others .... I just had other lenses I want to try while this lens sat. I won't sell it again though! This lens is crazy sharp with very little distortion!
Summary: I have a Canon 8-15 fisheye zoom, but wanted a rectilinear in the 14mm range so I bought a Sigma 14mm.....lens was not sharp overall, so I sent it back. Then I bought a new Canon 14mm f/2.8L II.....it didn't get sharp even in the center til about f/8...it went back. Then I saw this lens and tried it....I loved it. While not perfect, It blew away both the Canon (which cost over twice as much) and the other Sigma.
Summary: My expectations have been fully met. Lens was securely wrapped for shipping and is in very good condition. It works nicely. This is my first experience buying "used" photo equipment but I am convinced that this way both parties benefit. YanmingZhang certainly delivers quality on time. I am very satisfied and can highly recommend YanmingZhang.
Summary: Every now and then, a third party lens is actually all-around better than Nikon's own lenses and this is one of them. This is some great glass for full-frame Nikon cameras. I use mine on the D600. A little soft in the corners at 12, it is none-the-less still usable there. Its generally sharp across the entire focal range, and its great to have something this wide on a full frame camera. At half the price of the best Nikon comparison, its a steal.
Summary: I work everyday doing Japanese weddings. I used to use nikon's 14-24...but dropped it twice and had it service twice it was expensive...so decided to get this as back up...wow i was surprised...Sharp and very fast focus. Fast enough that i can have brides & grooms running with me and hold focus...I also like the extra reach it gives me on the wide end...the fact that is not 2.8 dose not bother me...Auto ISO and you are all good...
