The Sigma AF 4.0-5.6 70-300mm APO Macro Super is sharper and good
value.

Phoenix makes the best 3rd party lenses.

 

The Sigma is crap and will be more costly in the long run. No Canon owner
should ever waste money on Sigma.

 

Be aware that if you get a Sigma that
If you go to a newer camera it may need
to be rechipped to work, if that is possible.
Both the Canon 75-300 usm and 100-300
usm work well.

 

I just got the 100-300/4.5-5.6 and I'm happy with it. If you've never
used a lens with a ring-USM before, you'll absolutely love the fast
silent autofocus and full-time manual focus (especially for wildlife).
Canon's 75-300 lenses all lack a distance scale, and none have
ring-USMs. I think the 100-300 has slightly better optics as well.

good value until he upgrades that Rebel body to an Elan, 3 or 10D and finds
that Stigma lens won't work with his new body and he has to buy a proper
Canon lens instead

 

Folks, I had settled on getting the 70 - 200 L F4 when on one of the lens
review sites they rated the 75 - 300 F4 - 5.6 series 11 USM as almost the
same (4.1 to 4.0). Has anyone any experience with the optical difference
between the two lenses?

I have the 100-300 which is basically similar to the 75-300. It has low
contrast at the long end and not much resolution. It flops out under its
own weight and I wish I did not have it. From reviews I have read (no
experience) I have developed a lust for the 70-200 f4L to replace it.

The II or the III? The current lens is the III. Not sure about the II,
although I'd guess they're optically similar, but I can tell you that
the 70-200/4L is without a doubt vastly superior to the 75-300/4-5.6
III. I don't know what site you got the ratings from, but every other
report I have heard on the two lenses contradicts what you said about
the two lenses being comparable. Of course, one doesn't have the
200-300mm range, but I believe the 70-200 with a 1.4x TC (280mm,
f/5.6) is still sharper than the 75-300 @ 300mm. Of course, it also
costs a lot more. If you're on a bit of a budget, I'd get the
100-300/4-5.6 rather than the 75-300 (the main reason being the ring
USM). If you have the money though, go for the 70-200 and the TC...

I believe you have gotten some bad tests there.
