Have now already the second glass. The first was unfortunately on the hard stone floor and Canon could not repair cheaper, would cost more than a new one. But that's about the only criticism. The newer is again much more economical in power consumption than the first model, apparently has something changed in the hardware. While the old glass after a few hours of intensive use (eg when Birdrace) demanded new Eneloops, the newer this Stress keeps through the whole day and the batteries are not even half empty. Mounted on the tripod it was visually compared to my Zeiss Victory Although small weaknesses in sharpness and contrast, but freehand plays it then its advantage of ... the detail detectability is then much higher than the Wackelpunning-Zeiss. Would it therefore buy repeatedly.
