I've got a canon 75-300, also f/4-5.6. Nice lens, make sure the one you're getting has the 'ultrasonic' motor for faster focusing. You will probably need to carry a tripod around with you to avoid blurry images.
If you can afford a faster f/stop - go for it (otherwise donít plan on being able to take photos while dangling on a rope)
Depending if you're using a digital camera (and model) you get to x's your mm by 1.6 to get your true zoom.
400mm becomes 640mm!

i wish it was a little faster but i'm only looking to use it outside.

i was able to finally use this lens this weekend. here's a few shots of tom egan on my new route. this is a 35m mixed route with two hand crack roofs.

all shots were hand held.

I have one & find it pretty good. Pays to use a tripod at the long end & stop it down a little when you can - its not as sharp as the primes, but a lot lighter than a 100+200+300+400 L camera bag would be :wink:

have you found a "sweet spot" for the long range shots between 300-400mm?

i will definitely use a tripod next time. i wanted to give the image stabilization a try though.
