A step backwards from the D40
on 8 May 2013
In short, not as sharp as my old Nikon D40. Amazon very helpful in offering replacement and refund.
Detail. I've owned a Nikon D40 for several years, and decided to buy the D3100 as it was compatible with all my Nikon lenses. I bought from Amazon. I used the camera for the first time to photograph a 10k race. I was slightly disappointed with the images; some were out of focus, and most lacked colour; I felt that the camera was over exposing. I put the focus down to my needing to get used to a different focussing screen.
However, when I took some photos in the local arboretum I was very disappointed; they all lacked sharpness. I investigated further by setting up a tripod and photographing a bar code with text using the same lens. Every time the D40 produced sharper pictures using both manual and auto focus. I took the matter up with Nikon who gave me instructions on what settings to use to compare like with like. I took a series of three photos with the following settings:
Single point AF, Single Servo AF, Manual exposure
1. ISO 400, shutter speed 1/60 second and aperture f/5.6.
2. ISO 800, shutter speed 1/125 second and aperture f/5.6.
3. ISO 1600, shutter speed 1/125 second and aperture f/8.
Again, the D40 won every time. Nikon were less than helpful, but Amazon offered a replacement with no quibble; 10 out of 10 for service.
The replacement arrived and the results were the same; again the D40 was superior. I also tried using RAW images, with the sale result. So I have returned this 2nd camera and now need to have a re-think as to what to do; my D40 will fail at some time. Reading online reviews elsewhere, a number of others have identified a similar problem with the D3100.
