Owner reviews: Carl Zeiss Jena Flektogon 20 mm f/ 4

Сергей Бородин 1.1.2000 00:00:01
Period of use: 2 years

Strengths:

Incredible picture quality. You can shoot at 15 cm. No optical distortion. Small size and weight.

Weaknesses:

Construction is not very reliable, although of course much better than the modern plastic. Not too smooth focusing. Expensive 77mm filters. Without the hood catch glares.

Comments:

Almost a perfect wide-angle lens. It's great to use for shooting HD video on a Canon 5D mark2.

The quality of images compared with the Canon 17-40 L (sharpness in the center and edge, contrast, vignetting, distortion). With a wide margin Flektogon win in all parameters.
