Thanks for that information pentaxanne, you've certainly had plenty of experience with these lenses and that counts for more than all the marketing hype and MTF tests, I had heard before that the 150-500mm wasn't a very good buy. Seems to be the same with most things these days never as good as the items that they replace..... I've just bought a new TV and hard drive recorder and the old stuff was way better. I can't believe Panasonic have removed the delete button from the handset and I have to go to the second level of a menu to delete a recorded program.... great if you have to delete about half a dozen
Try one you might like it.
also i know what you mean about tecnology, My 50-500mm has to go back to sigma for af problems..
I have a strong feeling this will be my last sigma.

There is nothing wrong with it if you like pictures that look flat.

The word "helpful" has one L before the P, and one L at the end.
And it's "would have", not "would of".
Hope you found that helpful.

It's the film model not the DG so the IQ isn't as good.
Are you saying that Sigma are telling porkies when they say:
DG (Digital) Lenses:
The most suitable lenses for 35 mm film single-lens reflex cameras, as well as for digital SLR cameras. Sigma’s development of the DG (Digital) range of lenses has concentrated on the correction of distortion and aberrations. Magnification of chromatic aberration is particularly conspicuous with digital cameras. The optical designs and cutting-edge technology incorporated by Sigma eliminate flare and ghosting from the image sensor and create excellent color balance. Vignetting is minimized whilst marginal illumination is ensured. These high performance lenses are equally suited for digital and analogue cameras.
==================================
Possibly not too reliable but http://www.dyxum.com gave slightly higher marks to the DG version for sharpness.
We also have to bear in mind that Sigma lenses do tend to vary quite a bit even with supposedly identical lenses.
I also have had 3 150-500mm, and all 3 have not been as good as any of the 170-500mm,.
I now have a 170-500mm non dg (cost me £300) and a 50-500mm os cost me (£1250) and at 500mm wide open there about the same the 50-500mm is better at f8 and the af is quicker.
Sigma will tell you black is white if it gets them more money.

Err, actually pentaxanne, I also enjoy George's comments, acerbic though they often are.
What ever floats your boat.
