Nikon Pentax Olympus
What Digital Camera should i get?

I want to invest in a good camera, but I also want an relatively affordable option. My problem is that I don’t know if certain brands are even worth it – Casio, Olympus, Pentax, Sony… is a higher version of these worse than a lesser version of nikon and canon? for example, would it be better to buy a $1000 pentax camera or a $1000 canon?

I would recommend you either to buy a nikon or a canon Dslr Camera. Some of them are Nikon D5000, Canon T1i, Nikon D90
