Input:
User Review: I am a professional radiographer and photographer (25 years now) and I used both the Sony Mavica CD400 & CD300, as well as a Nikon Coolpix for this year's field research season x-raying mummies in Peru.  This means the cameras were pushed hard.....blowing sand, huge contrast ranges, high resolution radiographs needed, fast manual control of radical light conditions, etc.....essentially most of the tough conditions and imaging requirements you can imagine.  Here's what I found:
The Sony Mavica CD300 beat them all.  It's not the most expensive or the best resolution but we all thought it did the best job.
Mavica CD400: best resolution but extremely slow recording time made it impossible to work with most of the time....the CD300 often got 3-4 shots while the 400 was recording one.
Mavica CD300: not the best resolution, but now that I've done some prints for publication from it's highest res setting I will not be buying any more 400s....just not a significant enough difference, plus it's not as heavy or bulky.
Nikon Coolpix:  not in the running by comparison with the Sonys....although it is more lightweight....we are buying mini CDs for 33 cents each in bulk at BestBuy and getting 140-180 high res images per CD.....they are so easy to format, initialize, and copy on any CD burner that I can't believe we even considered using memory stiks, or USB downloads.
The best features are common to both the Sony Mavica CD300 and 400 series though.....manual control of the images, excellent close up abilities, decent wide angle (which can be enhanced with add-on lenses if necessary), and both rapid video and automatic functions with night focusing for flash, etc., etc.
Finally!  There is a great digital camera....but it isn't a Nikon.
