A little about DxO Mark

Since there has been a lot of interest in this camera after previous posts, I wanted to mention that DxO published their rating of the Nikon D3100 sensor.

DxOMark - Compare sensors

This chart compares the new Nikon D3100 to the highest-scoring APS-C sensor (Nikon D300s) and full-frame sensors (Nikon D3s).

I’ve used DxOMark a lot in passing discussions, and a friend (and recent Nikon D3100 owner) last month mentioned, “I don’t know how to read this.” Whoops!

I had better explain what these values mean.

dSLR video recommendations

Recently, some friends asked me what dSLR to purchase if they want to make movies with it. They aren’t experts at doing SLR photography.

Currently, if you are a beginner photographer and want a dSLR with video capability, the one I suggest is the Nikon D3100, ($700, Amazon, DPReview) which I have already written about earlier.

Nikon calls movie taking “D-movie.” It is currently the cheapest dSLR that can do video mode. It’s only one of three dSLRs that can do autofocus while taking video mode. This strikes me as the best balance between learning and using an entry level dSLR and being to take film-like movies. I’ll recommend some others below, but first I’d like to talk about the why and what of SLR movie-making (with the caveat that I’m a photographer, not a filmographer).Continue reading about dSLR movie-making after the jump

Nikon D3100

Last month, a friend asked me purchasing advice on a Nikon D5000. I told him, “Don’t. Nikon will be introducing a new D3000 replacement before Photokina.”

Today, Nikon has officially announced the Nikon D3100 entry level dSLR camera.

If you recall the big spreadsheet in my complete guide to purchasing an entry dSLR camera (etc), the big specification upgrades are: 14 megapixel, 1080p video and continuous AF.

Two other overlooked features of the D3100 are the improved ergonomics: the shooting mode is now chosen with a dial, and a lever now activates the movie mode. Both are going to be very welcome (for reasons I explained in my guide above).
