'Bridge' cameras have been selling very well (much to the tut-tutting of the mainstream photographic magazines who do not realise that carrying heavy binoculars and, often, a tripod and telescope as well means that an SLR with a long lens (often of inadequate length at that) is out of the question).
Canon soon followed Nikon, then Fuji and now Sony have followed with basically similar products; Nikon have followed up the P510 with the P520 (see my posts of 19 February 2013, 18 October 2012, 31 August 2012, 15 July 2012).
The Sony HX300 will be available in UK in early April. It is very difficult to say which model has the edge at the moment. The new Sony has more pixels but to see whether that compromises noise reduction we shall have to wait for the reviews. Disappointingly, it does not offer RAW, although with a 1200 mm equivalent lens and an output of 5184x3888 pixels, it could give that extra push that birders are always striving for. It is heavier than the Nikon but not so heavy as the Fuji
Here is my extraction of data from the technical details that are important to birders:
|Nikon P520||Canon SX50||Fuji HS50||Sony HX300|
|Optical Zoom (equiv)||24-1000||24-1200||24-1000||24-1200|
|Output Size (pixels)||4896x3612||4000x3000||4609x3456||5184x3888|
|Video||Full HD||Full HD||Full HD||Full HD|
On Amazon UK prices of these models today are: Nikon P520 £355 (the P510 is still available at £239); Canon SX50 £362; Fuji HS50 £470; Sony HX300 £419 (pre-order).
