Zoom Normal-Telephoto 50-500mm f/4-6.3 EX DG HSM Autofocus Lens for Olympus Digital Cameras (Four Thirds System) Sigma

Is there anyone out there who has this lens or has found a review.

Looks good to me.

Ah, the Bigma. I haven't seen a 4/3rds specific test, but there is a Canon mount Sigma 50-500 test on PhotoZone. I'd hate to take it backpacking, but it would make a great car lens especially considering on the 4/3rds cameras it would be a 100-1000mm 35mm equiv.

But also remember that at those equivelants what your shutterspeed would have to be to prevent softness due to camera shake. Handheld at 500mm you would need 1/1000 shutter speed and to acheive that at 6.3 is gonna be tough. So add to the weight of the lens and camera that tripod that your going to have to carry with you. Ugg thats alot to think about and care.

Mate it to a body with in-camera IS and that solves that problem.
edit to add: when Olympus comes out with in-camera IS.

I thought the "sunny 16" rule says that at f/8, your ISO would have to be above 500 to get 1/1000. Depending on how much noise your camera has, handholding may not be out of the question.

I very very seldom use any telephoto (or any lens actually) without a tripod, flash or occasionally a monopod. I definitely wouldn't try to hand hold this monster. I don't think my hiking tripod (gitzo 026) whould even hold it very steady. No this is a near the car only lens.
