positive:Super sharp (even wide open)
Solid Build
Nice Finish
F4 through out the range
Includes a nice case for storage.
Internal zoom
negative:Weight could be an issue for some
Not f2.8 but it would really be heavy then.
comment:I have not had a chance to do a direct comparison with the Sony 70-300 G but the pictures I have taken are super sharp. I would say it is just as sharp as the Sony or sharper.

The lens is excellent indoors as well with good lighting. I feel that it is sharper that the Sigma 70-200 HSM in low light conditions. I am considering selling it now for this reason. I used the lens last night at a concert with great results in my opinion.

It is sharper that the Beercan and the Big Beercan as well.

Using a Sigma 1.4X Tele-converter does not seem to affect IQ that much. The constant F4 is great for this lens.

For a non HSM lens, autofocusing is quite fast on the A700. Not all that loud either.

I love this lens! The price just shot up by almost $400 USD though. Thankfully I got it before it went up.

If you can get your hands on one for a reasonable price then go for it.

Note: One interesting note about this lens is that it is showing up as a 100-300 4.5-5.6 in the exif data of the raw files. Because of the camera firmware?
