<p>I have the Zeiss 21mm and the Canon 16-35mm II. I rarely use the Canon lens after buying the Zeiss. The colors, contrast and the sharpness of the Zeiss is superior to the 16-35mm II. There is some distortion with the lens, but I use PT lens to fix if I feel its necessary. Sometimes the distortion adds character to the shot so I leave it alone. I have used a lot of different lenses but the Zeiss 21mm is hands down the best and most unique lens that i have owned.</p>

The group of hot pixels that were present with my 5d was something I could not accept, especially with the amount of money I spent for the camera. The red cluster in the same exact spot was visible in all of my photos especially where there was alot of shadow detail. In my case I decided to send in to be mapped out. So you have to ask yourself if it is so noticeable that you need to clone or patch it out, that it might be worth it to send in to be fix. I assume under warranty at no charge. good luck chuck

HI Sergey

 

I had a similar problem with my 5D. I had a group of hot pixels showing up in one location. Useing a test similar, taking a photo with my lens cap on and using a shareware test to find out how many hot or dead pixels I had. Sorry I do not remember the name of the shareware, but on some of the canon forum websites you should be able to obtain it. It was more pronounced at the higher ISO but was still their in the lower ISo's as well. I have a canon repair center near my house, they re-mapped the sensor, not sure what that means. but the problem was fixed. Received the camera back within 10 days and have not had any problems. I hope that helps some. Chuck
