Just jumped ship from Pentax (k7) to D90 only reason being the selection of lens that the d90 has with it, like to (try) to take macro shots i only had m42 lens tube and 50mm manual lens.So when the d90 came a kocking with a tamron 90mm macro lens also 55-300mm nikkor lens 18-105mm kit lens also sigma 18-200mm, well it was a no brainer. Of load k7 hello d90 and iam well pleased with the results,know learning all the buttons menus.
