hi my nikon d50 has been having some issues and i have had the camera for 7 years. i am looking for an upgrade and had a look at 5100 nikon. i currently have the kit lense for my camera and a 70-200m. i would prob look at getting a 18-200 lense and just have 1 instead of 2. any opinions on the nikon 5100 or is there any other makes i should look at. max price would be 500 quid.
