<p><em>Thanks for the many good tips. I have been thinking about the D7100. I'm also experimeting with the AE/AF lock to focus, and also, as was recommended in one d5100 user guide, tilting the camera about 10-15 degrees to overide lack of contrast of desired target object, then reorienting for the shot.</em><br>
<em>Regarding fixed lenses, I have the Nikon 50mm f/1.8 AF-D which requires manual focusing for the lower end Nikons. Would the comparable 35mm nikon lens have any advantages? I like the 50mm since it approaches a portrait lens given the digital/film 1.5 ratio. I know that the relatively new Nikon 50mm AF-s f/1.8 G has an autofocus mode for the D5000 & D7000 series, but I've also read that it has noticeably more distoration. Does anyone know of any evidence regarding the latter claim. Any advice among choosing from among these three lenses? </em></p>
