What does he want the ‘bridge’ bit of the camera for? Most of these types of cameras seem to be shaped so you can get a massive zoom lens in.
If he is only taking landscape pics & pics of friends when out walking, does he need 42x (or 60x) optical zoom?? Perhaps he does if he takes pics of wildlife and stuff while he is out?
There are loads of bridge style cameras out there, but I am not sure which one would be ‘the best’. Have you tried searching for ‘bridge camera reviews’ or something? Most camera sites (dpreview, cameralabs, photographyblog etc.) normally have group test reviews.
If he is keen on a Nikon, take a look at something like the Coolpix p7700. It’s a competitor to something like the Canon G15 and is more of an ‘enthusiast compact’. I nearly bought one a while back after deciding that my little compact wasn’t that great.
There’s a review of it here: http://www.photographyblog.com/reviews/nikon_coolpix_p7700_review/
Just realised something. Most of those bridge cameras will have a viewfinder (albeit, normally only an electronic one), whereas the more compact cameras often do away with that. Do you know if he uses the viewfinder or the screen to frame his pictures? Might rule out the more compact options, if he does use the viewfinder.
