Okay you may remember a while back i posted a thread about "choosing photo" for a job as an equestrian photographer? Well I got accepted! (Almost just gotta do contracts and what not) but... He [the main boss guy/main photographer] was slightly worried about my gear holding me back... I'm aware of this and i know ill have to upgrade eventually... I'm in no position at this moment to go upgrading straight away but I have a few questions... Right now Im shooting with a Sony A200 (entry level) with a 75-300mm budget zoom lens... - When I upgrade should I upgrade my lenses alone for a start, so by doing that sticking with "sony" and eventually upgrading my camera body to the A900 for example? Do Sony have a big enough range in lenses? or what about doing this and using Sigma lenses etc with Sony mounts... OR... Should I switch to Canon or Nikon now, as they are the biggest brands and therefore would have the biggest range of lenses that id need for professional sports photgraphy? My camera i have now is actually rather good - But low light situations (e.g indoor arenas or crappy weather) somtimes makes it real hard, and putting the ISO up my my A200 I get noise at ISO800 + which definatly isnt ideal... So already I know Im havingissues with my gear... Sigh... Why cant I win lotto... Or marry a billionaire?
