went down to canon showroom today.....550D + 18-135 was in the showroom. i tried it out. tested the surrounding AF points and focusing speed. it's pretty fast wad. cldn't tell the difference between it and my 50D. and u guys shld know the DSLR portion at the back is poorly lighted. so i haf to say 550D is both thumbs up! its better than 50D in terms of IQ. the video is gorgeous too. my fren on the d90 was impressed with canon and wished nikon was so strong in the consumer market too. haha! he even said that if he had never ventured to nikon as his first dslr....he wld haf gotten the 550D right there and then. haha! so...those ppl with 550D, lucky you! im thinking of getting one myself soon. oh man, this BBB thing has to stop. Zzzzzzzzzzzzzzzz.
