Hey guys, I am looking to upgrade my camera from my old coolpix E8800 to a entry level professional DSLR. Friends have recommended the Cannon XTI or XSI to me but I would like some other opinions. I have a gig coming up doing photography in a low lighting so a high ISO and great performance in low light condions is a must. Are there any recommendations for a cannon or nikon in the 1000-1200 range? Any help would be very appriciated!
