Yes sure ....( this is Somona's hubby who's talking )
I don't make only shootings for my wife, also making macro, landscape, urban, animals etc....for different local newspapers here....
I got many bodies, and usually only use 2 of them for my common work, so a D1h and ( rarely ) a D1x ( because of the body is quite exactly like my old F5 )...the lenses are for sure the difference between a good or a bad pic...
There sre some you can easily carry everytime ( 17-55 mm, 70-300 mm, ...) but some specificaly for portraits ( 50 mm ) ....I use those bodies because all my old lenses have compatibilities with them , and I HATE the new DX format and motoring lenses....
The most important is to know excatly how to use your camera, and what are the advantages you can get with some or some lenses
