I have a Nikon D40, my first dSLR. I stupidly ignored a few people on this forum who advised me to get a D50 for the lens compatibility and now somewhat regret it. I absolutely love the D40 and have taken around 3000 shots in the couple of months I have had it, but I have discovered that what I really want is some fast primes. Oops... The D40 was a good camera to buy at the time because it is small, light, has a massive LCD and could be had new off amazon for a similar price to the older models people were suggesting (things that appeal to me), and at that stage I didn't really know I would get so into photography and want to use prime lenses. If a used D50 could be had for cheap, then I would sell up and 'downgrade', but on ebay most of them are more expensive than what I paid for the D40! I could probably pick up a 400D with its kit lens and then get the 50mm 1.8 for not much more than the old Nikon. Do you guys have any thoughts on this? Why are such old models so overpriced? Does anyone know of a place to pick up a D50 for a reasonable price? Will the mythical AF-S 50mm 'holy grail' of inexpensive dSLR photography ever materialise?!
