Re: 75-750mm ought to cover it, right?
Sure, it may reach 750mm.... but 750mm @ f/6.3 is pretty slow which means you're slowing down the shutter speed to let the proper amount of light in. Might be okay if all you use it for is bright sunny days and ISO 50 or 100.

It's a decent lens. A friend of mine uses one. f/6.3 isn't as much of an issue anymore with digital SLRs making ISO 200 and 400 look good.

My 200-400mm is 320-640mm! It's good on sunny days.

Re: 75-750mm ought to cover it, right?
Looking a the sharpness chart at SLRgear coke bottle bottoms would give better sharpness unless used at f8 @ 195mm.
I haven't lost my mind, it's on tape backup here somewhere...

Screw it, if I need that much zoom I'm just gonna call up LensRentals.com and rent the Canon 800mm f/5.6 IS. It's only $340.75 for a 4 day rental including shipping
Re: 75-750mm ought to cover it, right?
The sharpness at 400mm on my lens is kinda bad, so I try to keep it around f/8 and bump up the ISO.Brian_F wrote:Looking a the sharpness chart at SLRgear coke bottle bottoms would give better sharpness unless used at f8 @ 195mm.
