Instead of hijacking the Mac Thread, I thought I would open up this one. <BR> <BR>The only extender I tried was the 2x extender which I rented. It just didn't seem like it wanted to work with the AF on my 70-200mm. I have thought about renting the 1.4x extender which I hear is better. <BR> <BR>Anyone have any experience with these? <BR> <BR>-S

you coulda hijacked my thread i wouldn't have cared. ive never like extenders but ive only used them in my b&amp;w photo class and have never gotten the sharpness i want in my pics with the convertor. that being said i have never used one in a digital enviroment because i don't have my dslr yet

Swami, did your AF not work at all? According to bhphoto.com, "If the EF 70-200mm f/2.8L USM lens is attached to an EOS camera having multiple focusing points and an Extender is attached to the lens, only the center focusing point will be usable for AF." <BR> <BR>Is that the experience you had? Or did you get no AF period?

Those shots I posted in the 70-200 thread were taken with a 1.4X Kenko Pro 300 on. On certain lenses the quality hit isn't that great with a good 1.4X. I would venture to say the 70-200 with the 1.4 is as good or better then the new 70-300 IS @ 300 based on owning both. Sure it's not as good as the 300 f2.8 ($4K) or a 300f4 (over $1K) primes but it's certainly cheaper. I've always felt if you're using a lens constantly with an extender bite the cost bullet and get a longer lens but for occasional use it's a very useful and relatively inexpensive accessory.

Thumbs up on the Canon 1.4x TC.

The focus was off.. ok by off I mean WAY off. I was using auto focus on center dot, and also tried manual too.. but never could get it to work well... Granted I had just gotten my 70-200 like 2 weeks prior and was still getting dialed in with it.. but it just didn't give me a good impression. <BR> <BR>I want to rent the 1.4xTC and see how that goes. <BR> <BR>-S
