reviewswhat are people saying

"The lens is super sharp, lightweight compared to equivalent EF L lens with IS. I find myself using this lens more and more. Adapts well to Canon's 1.4X TC with little loss of IQ, although AF speed suffers a tiny bit. Never need a tripod with this baby!!"

"WOW! It is SHARP and contrasty and focuses fast on my 1Ds2. Very lightweight for a 400f4 and the IS seems to work exceptionally well."

bhphotovideo.com

"Might be VERY SLIGHTLY less sharp than the 300 (but then EVERY other lens is less sharp), it is still very acceptable and good compromise of weight and usability."
