Inside “dinky” cheaper Nikon DSLR cameras……surprises & information

  1. Ken, eye tune-up required.
    Nikon D2 and D3 only have 5 screws holding lens mount to the body.

    Plastic camera bodies need all the help they can get with both the number of screws used as well as the diameter, thread pitch and length.

    The Canon lens mount appeared to have been a stamped metal part verses the Nikon mount which is machined.

    If you used a #10 screw and it only had two threads of engagement, they would pull out in no time. Depth and thread pitch matters on composite materials. Soft materials use coarse threads, hard materials use fine threads.

  2. Hi Ken, I was shooting with a Nikon7100 in Liveview today and a fucking car drove by and the image sensor got flashed by the Sun reflecting off the windscreen, thus burning a nice blob in the upper center of the frame just like they warn about in the manual. Is it worth replacing the image sensor $ wise?? Thanks for any advice! Totally enjoy your videos especially the tear downs!! Hilarious!!!

  3. I thought the bigger cameras don't have a popup flash because the sensor and therefore the mirror and the penta-prism are larger. But the removal of the capacitor makes sense for space and cost.

  4. Thanks for an interesting video. I do want to nitpick about one little thing… the length of the lens mount threads isn't really a factor. You only need enough threads equal to the diameter of the fastener to reach full strength, more likely is the lack of a solid base to anchor those fasteners to. I'd guess that plenty of cameras have their lens mounts screwed into a big ol' block of plastic or nylon. I'd love to see a video comparing the teardown of an older Nikon film camera vs a DSLR. I bet you'll find a lot more metal in the older ones.
