What are brands of dslr cameras?

Besides canon, pantex and nikon.
i heard all dslrs work the same, is that true?
and give personal expiriences.

Sony makes a few. That's pretty much it.

Canon, Nikon are the top brands
then there are
Pentax
Fujifilm
Olympus
Sony
Kodak (actually their Dslrs are discontinued but you can get them 2nd hand)
Konica Minolta (again discontinued but available 2nd hand)
Panasonic

That is about it for Dslrs

Yes, all dslrs work the same but different brands and models have different facilities.
