i am going to be upgrading from my Canon XTI. i will be purchasing a 85mm 1.8 to take indoor shots of my daughter on stage during dance performaces mainly. i also would be using this camera for portaits, landscaping, and arcitectual photography. my main concern is that with my current camera, at ISO levels of 800 or more, the grainyness and noise are just unacceptable. i will not be able to use a flash, so that is not an option. i will not be able to move around during the performance, nor do i have the room for a tripod. i have learnt from another thread, that this is the lens i need. but what body would help me out too? i will be sitting in darkness, shooting a subject that is moderately lit. perhaps a combination of a new body and an IS lens would be another option? anyone with photos to post would also be appreciated. that way i can judge first hand on what to get. thank you in advance!!!
