Last i went to this forum and couldnt decide about a 24-70 or 17-40 ... I think i'm going with the 17-40 now but had this idea today, tell me if i'm wrong. I'm going to have a 1.4x converter sometime anyway so i'll get the converter and the 17-40 .... use them together for the "in-between" "lens" for now .... AWESOME!!!!

hrmmm... well first of all.. Canon EF 1.4x does not work on any zooms under 70mm. Second of all......sheeeeezez... this is the trick where the magician says.. : Kids, dont try this at home...

An extender/teleconverter is made for the longer focallengths (therefore the name is TELE).

Third and last.. get a beginners guide to photography and a book in the understanding series namely optics.

I can guarantee you that that combo wont be AWESOME!

(This might sound harsh, not my intention. But first you learn, then you teach)

Best regards

It simply won't work.

The tele-extenders will not physically attach to the 17-40mm.

There is nothing more to say.

Extender EF 1.4x II

This tele extender can be used with fixed focal length lenses 135mm and longer (except the 135mm f/2.8 Softfocus lens), and the EF 70-200 f/2.8L, 70-200 f/2.8L IS, 70-200 f/4.0L, and 100-400 f/4.5-5.6L IS zoom lenses. Superb optically, it preserves the image quality of the lens it's mounted to and multiplies its focal length 1.4x. Effective aperture is reduced by one f-stop; autofocus is possible on any EOS camera when combined with a lens having an f/4 or faster maximum aperture. The new version II maintains the outstanding optics of the previous version, and adds enhanced weather- resistant construction, and improved anti-reflective surfaces in the barrel.

And here,. check Sigmas compatibility chart. These converters are made for specific "Telephoto" lenses
