Hi every one,

I am just enquiring about the sigma 170-500mm lens for canon 450d.
Is there anyone here that uses one,or have had one could tell me about it.
Is it quick,are the pictured sharp etc..

Thanks in advance

I've got one, very cheap way to get 500mm lens, focus is very slow and noisy. Pictures are good on a sunny day, its f6.3 at 500mm.

I hope you get some feedback as I'd be keen to see what folk think.

I had one. Focussing is slow. Reasonably sharp once down to f/11 or so.

I traded mine in against a 150-500 OS version. Focussing is a bit faster (still not rapid but faster) and it's sharper at f/8 than the 170-500 is at f/11. Mainly did the trade to get the OS since I handhold most of the time and at f/6.3 at the widest, getting shutter speeds below 1/500th isn't that easy most of the year!

Both are considerably sharper than my old 500mm f/8 mirror lens but that did only cost me £45!

In conclusion to this in depth review of the lens (170-500), not perfect but a reasonable performer at the price.
