If you want to buy a DSLR go for a Nikon or a Canon. They are very reputed in DSLRS. Almost all professional photographers use either of them.
Both of them have a wide collection of lenses and accessories which will give you so much options.
Nikon dealer in Sri Lanka is Phototechnica (Kollupitiya)
Canon dealer is Metropoliton (The showroom is near HSBC Bambalapitiya)
Their prices are high but you'll be able to get cheaper prices at some shops at Petta.
