The nikon D40 camera is an entry level model in the nikon line up of digital SLR's. It was made with the the intention of capturing an audience of consumers that would conventionally purchase a point and shoot camera. In other words this camera was not designed for rigorous and serious photography, hence the reason for its short battery power. As a matter of fact you may notice that the battery life of a D40 actually is shorter than a comparable point and shoot camera. This is because the battery nikon used in the D40 has the same "lithium strength" as most high end point shoot cameras but will perform more battery draining functions because it is in essence an SLR. The D50's, D70's etc were not designed for the same consumer market as the D40. If you compare these cameras to the D40 you will notice they are physically bigger, have a stronger built quality, they have a top LCD etc. all to show that these cameras were made for an amateur photographer market as opposed to the point and shoot consumer. Furthermore, batteries that are used in higher end cameras like the D80 and D200 can also be used in a D50 but not in a D40. Further showing that the D40 is rather like a 'stepchild' in the nikon DSLR family, than a bona fide nikon DSLR. There are other issues like lens compatibility that are a problem with the D40 when compared with its bigger siblings.
The best flash options for the Nikon D50 camera are the Nikon SB-600 and SB-800 speedlights, as they are compatible with the camera and offer advanced features for better lighting control.
A review of the Nikon D40 and D40x digital cameras by Nikon expert Thom All of those things come into play when choosing between a D40 and a D50, You can find the full comparison of current Nikon DSLRs here if you want the full list.
Most Nikon lens will work in complete manual mode, but to get the most from the lens (auto-focus, metering) stick to Nikkor lenses with AF or G in the title. Full comparability chart in the related links below.
Yes, it will fit. However, you will still need to see if the lens you have has or does not have features like autofocus or CPU connectors that will carry all the info that your camera needs... If it is a Nikon Lens it will work fine. So will others like Sigma, Tamron and Tokina. Carl Zeiss may not give you all the functions but will work in manual mode.
