Sigma 1.4x Converter With Rebel

Mon Nov 29, 2004 2:52 pm

Does anyone use this converter with sigma 70-200 and Rebel? Could you share your opinion? I've heard that there may be some problems. The question is to buy or not to buy.

thanks
Daniel

I used the 1.4x with the 70-200 f2.8 albeit with a Canon D60 with no problems whatsoever !

it still remains auto focus and pin sharp , with no visible loss of quality at all , and the lens then runs at F4

hope that helps

Tony

Hi Daniel,

Do a search on my name in the photos section, Simon Gregory.

I have a number of shots uploaded using the 70-200 F2.8 EX HSM and the 1.4x EX converter. I am very happy with the results.

Regards Simon

1.4 works fine on the 70-200 2.0 is crap though very soft at the longer reaches so beware.

They both work fine Daniel, even stacked on top of each other.
Don't know where Paul's statement is coming from but it might because he is using Nikon and i have seen earlier topics where Nikon users were not happy with the Sigma combo.
On your Canon though it is absolutely no problem at all although i would not try a Canon 70-200 on a Sigma tc and v.v.

Here are some examples for which i used a Sigma 70-200/2.8 EX(hsm) combined with a 2.0 tc.

Willem, those are great examples of the 2.0 and the 70-200 EX.

You def. want to stop it down a bit, the 2.0 gets a little soft wide open (5.6)

Yes that's true HappyClick  Smile/happy/getting dizzy, a wide open lens will always be a tad softer then a stopped down one.
Far from unworkable though.

This example is wide open and maximum range.

I've had no problem plugging in a Sigma 1.4x between my 300D and 70-200 f/4 L. Here's an example: (please, no cheap hits)
