Anyone have Sigma Af EX DG 500mm f4.5

Not that I can really afford this at this moment but I am looking for a long fast lens with EX image IQ. Would love the Pentax 600mm f4 but I think that is more than twice the price so unless I win the lottery.
If I save I can probably get the Sigma in about a year.

I am also wonddering if anyone has or has used the older model Sigma APO 500 f4.5 P/KA manual focus around 15 years old. How was its IQ and what would it be worth on the market.

regards
Oren

There is also one report in the lens review section. I plan to add my comments later in the summer.

I have the Sigma EX DG 500mm f4.5 and it's a lovely lens. Relatively small for its focal length (compared to other makes), but still heavy to lug around. It's sharp wide open and great fun to use. A little noisy on the screw drive, but not so bad that it makes any difference from a bird hide.

The current Sigma 500/4.5 is half the weight of the FA 600/4. I've used it on Canon mount is it's really good in terms of weight vs. focal length (7 lb, 500mm).

Lots of birding images with it if you need some samples - let me know!

Regards,
Marc
