Having owned a D50, don't judge Nikon's performance by it's AF system. It isn't anywhere near fast and is the real weak link in that setup. The D80 will be noticably faster, and something like a D300 will show a night & day difference. The D50's a nice little camera outside the bad viewfinder, but speed is not its strong point and the Multi-CAM900 5 point AF system used in it has always sucked (It sucked on the F80 and has sucked on everything Nikon's used it on since. Thankfully it's now dead). -Adam -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
