首先，我是阿佳的忠实信徒。不久，也准备购入一台5d2，所以，在选器材的同时，也在关注国外人士对此器材的评价，也就经常浏览国外的网站。偶然的发现对5d2的一些评论。在夜间，远距离对高光辉度物体拍摄时，会出现黑点，即使在iso100的时候，非常得无法理解。同时也希望有更多的交流。
国外人士的有关评价：Canon took a huge beating on its latest Mark III DSLRs’ flagships with the controversial Auto-Focus snafu. Make no mistake; the newest release and much-promising 5D sequel if continue to face technicalities, will tear them into pieces, losing more prominent domination in pro as well as prosumer markets. Early reports in favor of the improved AF, white balance and high ISO sensitivity despite the increased sensor sizes; however, like most cameras at its initial rollout, 5D mark II can’t escape the early-adopter bugs.

Facing the toughest pixel-peepers, images taken with the new camera shown clusters of black dots/edges on the right side of blown highlight areas. Numerous discussions are heating up at community forums; some reported artifacts are presented on raw data (not post-processing errors) and are more rampant in high ISO but appeared less on low iso shots, others, include a Canon tech response to the ill-effects are limited on long exposures with high ISO images, similar occurrences have been reported and fixed via firmware in previous models.

Frankly, it’s not an issue at alarming rate; of course, unless your works involve pixel-peeping beyond 100% or billboard-sized commercial printing. The tiny black dots on aren’t likely to affect the overall 21MP image. Thanks goodness the issue is said to be easily repaired, personally, I don’t think the Canon’s biggest blunder the past decade could take another hit.

买大马三吧!

晕，这是真滴么。。。

这放大已经超过100%了。。。没有什么价值吧。。。
