The quick answer
The Nikon D3100 is an excellent value for photography on a tight budget. It can produce good results with proper technique, even though its specifications are outdated beside modern cameras.
For video, I recommend better options such as the Sony NEX-5N or even a smartphone. The D3100’s appeal is affordable still photography, rather than video features.

Why it still works for photos
Released in 2010, the D3100 remains surprisingly capable for photography on a budget. The 14MP sensor holds up well for its age, producing solid images with proper lighting and composition.
Autofocus is decent for photos with supported lenses, although it is not as fast as modern cameras. The photos do not match the sharpness or dynamic range of newer models, but they are more than sufficient for casual photography.
The roughly $75 quoted in my original video was a used price at the time. At that price, the D3100 punches above its weight for stills, even though its video functionality is severely outdated.
Video is the main limitation
Video autofocus is too slow to rely on. ISO, aperture, and shutter speed are adjusted automatically during recording, which limits creative control. There is no microphone input, so audio is limited to the internal microphone.
Smartphones and budget mirrorless cameras such as the Sony NEX-5N outperform it for video. The NEX-5N offers 1080p at 60fps, a flip-up screen, and manual controls.
It is possible to get decent footage with perfect lighting and composition, but the automatic settings and missing features make the D3100 a poor choice for video.
How it compares with newer cameras
Modern cameras such as the Sony A7 IV and Canon EOS R5 are miles ahead in resolution, autofocus, video capabilities, and overall image quality. The $1,500 to $6,000 prices discussed in the original article, however, are well beyond many people’s budgets.
The D3100’s appeal is affordability. With good lighting and the right lenses, it can produce great photos at a fraction of the cost of modern systems.
Who I would recommend it to
The D3100 is an excellent value for photography on a tight budget. It suits beginners learning photography, casual photographers who do not need cutting-edge features, and people who already own one or received it as a hand-me-down.
Its specifications are outdated, but proper technique can still produce good results. I would not recommend it to video creators who need manual controls and better resolution, or to professionals and enthusiasts who need advanced features. For video, the Sony NEX-5N or even a smartphone is a better option.
