There is only lens reviews in APS-C in http://www.photozone.de originally. After Canon released the Full Format 5DmarkⅡ camera.  EOS (Full Format) Lens Tests add to photozone.  Now only includes Canon EF 50mm f/1.8 II .  Adding other lens for the future is expectable.

http://www.photozone.de analyses the lens in distortions, Vignetting, resolution, CAs,  bokeh. There are some sample images also. Finally a verdict in Optical Quality, Mechanical Quality, Price/Performance. This web is a very useful reference for purchasing lens.

http://www.photozone.de 本来 只有APS-C画幅下镜头的评测，在佳能高像素全幅相机无敌兔发布后，网站增加了佳能口镜头在无敌兔下的评测，现在仅有Canon EF 50mm f/1.8 II一款，相信陆续都会加进去了。

http://www.photozone.de 评测相机从桶枕形变形、四角失光、分辨率、色差、焦外表现等方面对镜头进行分析，并有几张实际拍摄的图片。最终对镜头做出光学性能、机械性能、性价比的结论，对购买镜头很有参考价值。
