New Camera...Canon400D, Nikon D80 or Sony Ahpha

Canon Or Nikon??

i have do some market survey recently, camara in my mind will be Canon 350D or 400D, Nikon D70 or D80 and Sony Alpha A-100 is my targeted camera, i will consider either one of them, but recently i found that Sony Alpha camera have 1 major "Disadvantage"...this disadvancetage is inherite from the previous company call minolta

alot professional say that minolta is a selfish SLR manufacture..why people say like that? B'cos the mouthing are special, it only can fit it own lence, other brand are not able to use! that mean not compatible with other brand. So Sony Are Out in My Mind...How would you fell with Sony?

May be just consider Canon and Nikon, but Nikon Camera outlook are not nice, size are too big, especially D70, but D80 already modify literbit, size are smaller

For Canon, the Size of 400D also smaller then 350D, the size make me fell like it is a TOY...hahaha....

here is some review of Sony Alpha, Canon 400D and Nikon D80
