hey guys im looking to buy 2 or 3 new lenses for my A350

what they will be used for are weddings some of the time. allot of portret work. and sports photography...

i have found that with the weddings i have been asked to do i have a 28-70mm lens which some of the time i find its not long enuff.... and i have a 55-200mm lens which is not shor enuff. so i was thinking of looking at some thing that has a wider length...

for the portret work and probably be used for the nice formal wedding shoots is a 50mm prime lens 1.8 or 1.4... i wont some very nice sharp pics.

and for the sports i was thinking of some along the lines of a 200 to 500 MM lens that can get down to around 5.6-6.5???

dose this sound ok or are there better options out there that ive missed? im still quite new to all this. ive still only got my twin lens kit with allot of accessoires
