Last night I've tested my Sigma 2x converter with my Sigma 50-500 lens to see how they will perform in low light conditions. Firstly it's quite tricky using this combination - the slightest movement results in a blur. ( Anything slower than 40th of a second - and the movement of THE MOON will cause a blur effect ! ) The mirror lock up function is a must ! It's a bit difficult using the manual focus with so little light - but with a bit of practice one gets lucky now and then ! This one was at full zoom - 1000mm.
