Summary: This camera is built for the beginner to moderate photographer. The camera is light weight compared to other Nikon DSLR's, while at the same time providing the Nikon signature lens and operating system. The only problem I had was when you want to tak action shots, compared to some of the other models (D80) it does have a slight delay, and it also requires a corded remote. Other than that it is a great investment!!!
Summary: This camera is not, I repeat not for the multi decade Nikon user... This is a great starter DSLR, before this I had the Canon Digital Rebel XT, that was great camera but this is better. I still consider myself an ametur user of DSLR's which is what Nikon was specifically targeting when they designed this camera. It builds on many of their successes, the auto modes work well, the lens takes great shots especially if you play with manual focus.
Pros: Fast / Accurate Auto-Focus, Fast Shutter Speed, Good Image Quality, Good Image Stabilization
Cons: Noisy At High ISO, Poor In Low Light, View finder is too flush
Summary: This is my first DSLR camera and I love it! It is so easy to use. It is a little confusing at first but once I got the hang of it my pictures turned out amazing. I take pictures of people and nature and the picture always turn out great. It also has a really good battery life too. It has a couple faults with the focus but maybe it's because I'm new to the camera. overall it was an amazing camera.
Summary: All Pros. Only con is noisy Focus Motor nulls Hi def video advantage, aside from the no auto focus motor on body thingie which could have saved users from expensive S version lenses. Just the reason for one star less. Overall I love this toy. Light and versatile.
Summary: I am very happy with the camera, I could have not got a better product for my introduction to Digital photography and I have only been improving and taking better photos everytime. The rest of the articles are not very useful, except for a couple of lens and filters.
Summary: The Nikon D3100 can use older Nikkor E Series lenses, but its light meter does not work with those lenses -- you need to determine correct exposure (F-stop and shutter speed) independent of the camera. This is a major gripe with me as it means the D3100 is not fully backward compatible with the many Nikkor lenses I already own. Using those lenses, the D3100 is more manual than my older manual cameras.
