Should I upgrade my D5000 or buy a longer Nikon 200-500mm lens to give me more reach than my 70-300mm lens? Stephen Broughton, via email
Jason says... Nikon’s recently launched 200-500mm VR is certainly a tempting buy. It’s a good quality lens and competitively priced at around £1180/$1400. On the other hand, the D5000 is a relatively old camera. Its image sensor has a fairly small megapixel count of 12.3 megapixels, and the image processor is outdated. You’d be better off upgrading to a D7200 for around £870/$1050. It’s a much more advanced camera with a 24-megapixel image sensor, an updated image processor, a much improved autofocus system and a faster continuous drive rate.
