I dont have that much money to get the L so Im debating on these two lenses:
Sigma 70-300mm f/4-5.6 APO Macro Super II or the Canon ef 75-300 III USM non IS.
If anybody has both, can you please input on which one is better. Strong points and weak?
I always assumed that a third party lens wouldn't be as good but after comparing pics of the two, I cant see a difference.

thanks

I have seen results from the Sigma 70-300mm APO Macro Super II and have been impressed. I have never used it but it looks to be a fairly sharp compared to the Canon EF 75-300mm f/4-5.6 II which I do have. I do not have the USM but I believe the optics are the same in both the one I have and the USM. Someone please correct me if I am wrong.

I am considering the Sigma 70-300mm APO Macro Super II myself and getting rid of my Canon EF 75-300mm. I was impressed by this thread that was posted about a week ago. You may want to have a look. Link To Related Forum Discussion

I would go with the Sigma.

I have the canon ef 75-300 and then I also have the Sigma 28-200mm
I much prefer the Sigma and I may too get rid of my canon and replace with another Sigma. The Canon seems to have a hard time focusing in the AF mode and doesn't seem as sharp as my Sigma.

I went to check out Ebay after posting and found the Sigma lens on there for a "buy it now" price of 114.95.

I don't find the 75-300USM to be a bad lens, it just depends on the lighting. You need to keep the shutter fast enough to have it sharp. I think that is the problem most people have, they have too little light and then it is too soft because of slight movement.
My last entry was taken with that lens and I think it came out pretty sharp.
these baby geesewere also taken with it.

I have used both. When i first got my 300d i borrowed the canon 75-300 III usm and used it for about 2 months. I had no problems with the lens and it seemed sharp enough. I even got a ribbon with it.


However after a bit of research on dpreview.com i read some very good reports on the sigma 70-300mm f/4-5.6 APO Macro Super II and most agree its sharper then the canon. But the main reason i picked the sigma over the canon was for the macro feature because at the moment i can`t afford a dedicated macro lens at the moment.

The sigma lens is a more substantial lens which i liked and comes with a very nice bag and lens hood. Focusing from what i can remember was quieter on the canon lens but its not something that bothers me. Speed wise i can`t say i noticed much difference. The sigma is longer than the canon especially in macro mode.
The sigma is a great lens for the money, i payed £145. I think the canon is about £120.
On a cloudy day expect to bump up the ISO alot.

Mark.

Watch that...it is probably the cheaper "DL" version of the lens, not the "APO". Also be sure that you get the "II" version of the lens. The older version does not work with the digitals.

I just recieved my Sigma two days ago from B&H ($209). I haven't had much chance to play with it though, since it's been cloudy both days. :(

In my experience the Sigma 70-300mm APO super macro 2 is a little bit better lens than the Canon version. The Sigma beats the Canon is the amount of CA that it produces and I am pretty sure can yield more magnification for macro shots though I haven̢۪t used either lens in a while. If you do decide to go Canon I would recommend going with the non-USM version of the lens. The USM version uses a micro-USM motor and is really not noticeably faster than the micro motor in the non-USM version though it is quieter.
