next PZ Lens Test Report - Canon EF 100-400mm f/4.5-5.6 USM L IS

Thanks Klaus for an excellent review. I wanted to question whether the 3.5 star optical rating could have been a 4 (especially considering what the alternatives are) but I decided against it <img src='<#EMO_DIR#>/laugh.gif' class='bbc_emoticon' alt=':lol:' /> , knowing all the caveats around the star ratings <img src='<#EMO_DIR#>/rolleyes.gif' class='bbc_emoticon' alt='Rolleyes' />

Were you considering to update the existing APS-C review to a test on the 50D or is it not worth the trouble? Would you expect to see much difference?


I considered to do a retest but the main problem is testing space at the moment. 500mm (FF) are about the finishing line and with the 100-400L we'd have been at 640mm. I'm afraid that for the time being I can only test lenses on APS-C with a max. of 300mm - unless I start testing outdoor again (which is a pain).

However, I reckon that the charts would have looked the same as in the older test.

As for the 3.5* rating - I think it has no tendency towards 4* actually. Remember that these are absolute ratings, not relative ones.

FWIW ... I've just ordered the 300/4L IS & 400/5.6L for testing ...
