Hi all,
I'm hoping to buy the Sigma 50mm f/2.8 EX DG Macro lens alongside the Canon Macro Twin Lite MT-24EX Flash over the next couple of weeks, and I'm wondering whether people believe that this is a good choice of equipment for macro work or not. I mean, first of all, are the lens and the flash compatible, i.e. will the flash lock on to the lens even if it's not Canon? Secondly, is Sigma's 50mm f/2.8 EX DG Macro lens a good lens? What is it about the 70mm and the 105mm lenses that makes them worth so much more?
Any help would be much appreciated!
Many thanks,
Jack McEntire
