Ok - it's not really in the hizouse... but I did get to spend some quality time with a D50 and overall I've come to several conclusions about the camera:
1) Finally - A true point & shoot DSLR!
Many have tried, but Nikon really did it with the D50. The JPG's are a little more processed than what DSLR users are used to getting from their cameras. They are sharpened and saturated a bit more that it's sibling Nikon D70/s and cousin Canon & Pentax offerings. The Matrix Metering II (used in the D2x & D2hs,) really seems to help give this camera the ability to make great exposures without thinking about much of anything. The iTTL is not wireless, but the flash (even the pop-up) is very good. Surprizingly the AWB is not a cold as the D100 and D70 tended to be.
2) Fat Boy Light
The D50 is a little fatter, or wider from back to front, than the D70/s. Making it ideal for folks with larger hands when compared to the likes of the Rebel XT. It lacks the aluminum inner structure that adorn the D100 and D70/s making it significantly lighter. The weight of the camera is almost nothing in DSLR terms making it comfortable for people with small hands to operate and actually women seem to prefer this over the D70/s because of the weight (my informal test suggests this.... I asked 1/2 a dozen to tell me what they thought.) So I suppose my conclusion of the body design is that it's size & weight are well balanced for many types of users.
Because of it's intended audience, the D50's body is very simplified with it's outer-button placment. It is more menu driven than the D70/s and lacks more advanced features that many have become accustomed to (such as quick format with the two external buttons.) Along the same vein as the quick format feature, Nikon instead put a reset feature where the user can hold in two external buttons (marked with a green dot) that will reset any settings that may have been changed from default (ie- exposure compensation, flash mode, WB, etc.)
The D50 has a damn big LCD, though it is sadly the first Nikon to not include an LCD cover to protect from scratches. The large 2" LCD is very bright, sharp, & shows good color and gradients. In a very welcome change from the D70/s, when viewing a vertically rotated image, when one zooms in to a displayed image, the zoomed area uses the entire LCD, not the smaller area of the rotated image... D70/s users will know what I'm talking about. (Honestly, the could update the firmware to take care of this.)
It's a DSLR for the entry level user. Most advanced ameatures and professionals will find it a little too menu-driven and dumbed down compared to the D70/s or similar cameras. The body by comparrison feels a little cheap (like the original Digital Rebel) and the kit 18-55 ED lens doesn't hold a flame to the 18-70 ED that arrives with the D70/s. While the body is clearly aimed at soccer mom, or family snapshooters, the image quality of the D50 is excellent and could easily satisfy the most discerning of photographers.
Would I buy one?
For myself: NO! - I'm waaaay to spoiled with D2's!
For my wife: NO - she just got a D70s! Only I get to carry more than 1 camera! If she wasn't helping me with weddings, then: SURE!
For my mother & father: SURE! - They are snapshooters!
