8 out of 10 points and recommendedExcellent image quality, colors are quite amazing with a circ. polarizer. I was trying this lens out against the Zeiss 18mm and the Rokinon 14mm for Sony on my A7 and my big Nikon. No contest. I especially like the 'look' one gets with the 15mm. Some thincost, and cost of the polarizer.
Optical performance of this ZE 15 f/2.8 Distagon is astounding. It is manual focus and demands a deliberate approach to conceiving and framing compositions.reviewed November 21st, 2015 (purchased for $2,950)
The Canon 14L II has AF and is a fine performer. The Zeiss, however, is superior with its precision focus ring, flatter field, and sharp rendition right out to the corners. I expect the Zeiss to excel in photography of the northern lights.
I noticed that infinity focus on my Canon 5D Mark III is not at the hard stop of the focus ring. Furthermore, the AF confirmation beep is not reliable even with micro-adjustment. To extract the best out of this lens, use Live View.
