" It was mentioned earlier that the Sig might not be that sharp at 500-600 but I do not see that. I am getting tack sharp images wide open with it."
Truth of the matter is, it is just as sharp. Only the MTF chart collectors might say differently. MTF charts have nothing to do with how well a lens does in the real world. They are how well they do in a selective laboratory environment. Most of us don't shoot in labs nor do we photograph charts! Enjoy and use your lens without concern.
But I will add, you shoul notice a bit of an improvement shooting at f8. I use my "S" most of the time, true, but I almost always use Av set to f8. However when I pick up the "C" or the Tamron, I do the same. It seems to me most if not all lenses do better down one stop. Actually pretty true from either end, wide open or at the smallest aperture (back one stop). One stop is more better!
I think Canon missed the boat not offering a 150-600mm zoom. Rumors are there is one coming but you know how rumors go. Nobody on the planet makes better lenses than Canon. That has always been Canon's strong suit.
Brand-N has a 200-500mm. IMHO, I would prefer a 200-600mm over the 150-600mm. How many times or much of the time do you use your 150-600mm at 150mm? I would wager not often.

I'm really enjoying this conversation. You are dead on about almost all lenses stopping down even 1/3 stops to get sharper images. Espescially older lenses from a few years back to further back. Lately it seems like Canon is trying to stick to the advertised apperature and making it sharp from begining to end on the more recent editions. Now it looks like Sigma and Tamron are trying to step up their game as well which bodes well for all of us.
I'm scared to see what price Canon would put on a 150-600!! That baby would probably cost an arm and a leg. Maybe two legs haha. But I could see it being the ultimate bird lens short of their 500 prime. As for the 200-600 I'd be on the fence about it. I do use the lower register some but I guess I could give it up if got me even better performance out of the rest of the lens. At the moment I'm so impressed with it that all I could see improving woudl be focus speed though but I guess I'm still in my honeymoon phase with it though.

"That baby would probably cost an arm and a leg."
According to the rumors, it would be in the same range as the Siggy "S" and ef 100-400mm II zoom. Remember it is supposed to be direct competition to the crop of 150-600 zooms out there. It is not an "L" lens.
"A rumor about a possible Canon EF 200-600mm f/4.5-5.6 IS lens appeared on the web. The lens is said to be not an “L” lens, and to have an indicative price of $1,700. A “budget lens”, so to say.
The EF 200-600mm f/4.5-5.6 IS would compete with Sigma’s and Tamron’s super-zoom offerings. Moreover, an external dedicated teleconverter may also be announced. A patent for an optical formula referring to a 200-600mm lens was spotted last year."
If they do actually come out with it, I will have one in a hearbeat.

Nice shot, pris796.
I've had a Sigma 150-500, which had strong vignetting, and now the 150-600, and both of them had soft focus at their maximum focal lengths when you focused at infinity. Try taking some shots of the Moon with it. Manually focus it, too.

Thank you, I am saving money for new lens, I only have 70-300, not sure yet what I will get but I want something that I can get shots like yours. Waddizzle great shots you took of the Birds.
