Hello,



I couldn't find the Canon 75-300 f4-5.6 IS USM III review here. I am trying to compare its sharpness with some other lenses from this class.

There's no such thing as a IS USM III.

Canon has 3x 70-300 IS lenses.



These two:

Plus the new L IS.

They had a 75-300 USM III in the past as well as the 75-300 IS USM.



Both have long been discontinued, though, and I'm afraid that they won't be reviewed here, ever.



Regarding performance: don't expect too much from anything older than the 70-300 IS USM, especially on a modern DSLR.

The 70-300 IS USM has not been discontinued. It is still listed over at Canon.de and widely available.

I didn't say so <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='' />



The 75-300 IS USM was discontinued when the 70-300 IS USM was announced.



However, I just realized that the 75-300 USM III (non-IS) still seems to be a current lens.

I don't know why, but a lot of shops outside Europe seem to bundle this lens instead of the (equally priced) 55-250 IS with new cameras.

But who understands Canon? They don't even offer the 7D + 15-85mm kit in the US (although they do offer it with the 28-135).



IMHO Canon could cut a whole bunch of old, long superseeded lenses out of their lineup.
