Hey guys, im standing here in a digital camera shop looking at a Sigma 100-300 f4 APO zoom lens and wondering whether or not to buy it - and whether anybody has experience in using it out there - Nikon mount. Its about $550 is it worth it?
If they had a 2.8 version i would get it but this is the f4. Just hoping someone out there can help me.
Many thanks.
Andrew.
