D300, Sigma 8mmm 3.5 - which agnos
Me again, I tried to search for this one as I've asked it already but couldn't find it.
I've got a Manfrotto tripod, the D300 and the Sigma 8mm beloved by so many on here and now, finally, I've got the cash for an agnos but i dont really understand what to go for.
I dont quite understand the site...there are rings and things but I want basically eaverything i need. Dave suggested a couple of types I remember but I coulnt work out which one did what things.
Sorry - if anyone can help I'd appreciate it.
