I've looked all day to find a dealer in Calgary that carries the Sigma 100-300 F4 to try on my Rebel XT. You have to special order them and then there is no return or exchange privilege if you don like it.

Several shops recommended the Canon EF 70-200 mm F4 USM and then add a 1.4 extender. Works out to the same price of the Sigma.

Any thoughts, comments on that combination?

Thanks

I have the 70-200 f/4 and the 1.4 TC. I am well pleased with the combo but many people will tell you that avoiding the TC is preferable. I think I would agree on the basis of optical quality and the fact that using a TC is a bit more cumbersome. This particular combo, however, is quite good and still very light weight compared to the native options (ie sigma 100-300). I do not have the Sigma for a direct comparison but again, I'm pleased with the L/1.4TC combo. I'm also pleased with the 70-300 DO IS which is going to be my replacement for the subject combo.

Yes

1. The Canon EF 70-200 f/4L + x1.4TC becomes 98-280 f/5.6 which is a stop slower than the Sigma 100-300 f/4
2. This is how Canon marketing works - hook you in with an inexpensive 'L' lens -> when everyone figure out that they need more reach
3. The 100-400 f/4-5.6 will be waiting...
-> Bottom line you've just bought two lenses!


The Sigma 100-300 f/4 with a 1.4x TC is now a 140-420 f/5.6
-> Bottom line you only need one lens, same range, same speed but a slighly longer reach! :-)


Now which one is heavier: A 100-300 f/4 EX or a 70-200 f/4L plus a 100-400 f4.5-5.6L?
... and you don't even need a camera bag to carry it in :blah:


This 100-300 f/4 is always in short supply since it was released - ever wonder why? http://morrobayphotos.com/Sigma/100-300/
... and why is there so many 70-200 f/4L on Ebay? http://www.stevesforums.com/forums/v...99&forum_id=65

Thanks NHL. I'll keep looking around town for the Sigma. Maybe I can pick one up when I'm on holidays in the States this summer.

Anyone know of a reputable online dealer with a good return policy? Preferably in Canada so I can get the warranty.

Thanks
