I think I now have my mind set on the Sigma 50-500mm F4-6.3 EX DG APO HSM
Goes for $999.99 on B&H and I'm having trouble finding bad reviews.
Anyone have any thoughts? Anyone have this lens?
I have one.
I call it "The Beast" because it really is a beast of a lens.
4 pounds plus to lug around, and plan on dropping another $100 if you want a decent UV protector filter on it because it uses an odd size.
The lens is fairly sharp, not bad at all. Build quality is excellent.
People complain about the "lens creep" but this lens doesn't creep, it shoots out as fast as a gun if you point it down... it does have a lock though if you care about that stuff.
Focus is good and accurate on my Nikons... keep in mind it is a 6.3 at 500 mm which means some Canons will struggle to AF with it.
I shoot entirely handheld (I don't even own a non-astronomical tripod), and I find the lens is tricky to get a clear shot with unless it is completely braced at over 300mm.
500mm lenses have a shooting style all their own.
Plan on shooting HIGH ISO even in sunlight unless this thing is on a tripod at more than 300mm... it takes me 1/1000th of a second to hold it steady when wracked out to 400+
Here are a couple of pix I took with mine. They are not great pix, it is just went into the back files and dragged out a couple to give you an idea of what the lens does:
