EOS 4000D modification

#1 Post by Dave S » Sun Sep 08, 2019 11:35 am

I bought an EOS 4000d camera, specifically for use with the microscope, because while not expensive, it has a 18Mp APS-C sensor, is relatively small, made of lightweight plastic, unlike my EOS 5d MklV, which is big, heavy, and expensive.

Using the 4000d on battery was likely to prove a bit of a pain, during long sessions in 'Live View', and so a main power supply was needed.

These come in the form of a dummy battery, into which plugs a lead from the AC to DC step down power supply. Unfortunately, unlike most DSLRs, the 4000d does not have any provision for connecting to an external power supply, so using a dummy battery is the only option.

This gives rise to another problem, how to get the cable from the dummy battery out from the camera body. Leaving the battery compartment door open, is not an option, because a lug on the inside of the door, operates a recessed micro switch, when the door is closed.

So, my solution was to file a small slot in the camera body, to allow access fro the cable, and the door to be closed. There is no way I would take a file to an expensive camera, but the 4000d was bought specifically for use with a microscope, and cost only £229.

The dummy battery, and associated power supply, cost £12.99 from Amazon, and delivered free.

I now have an ideal size, and weight, 18Mp DSLR that runs off an external powers supply, as opposed to a re-chargeable battery.

Thanks for that Dave. I was about to make a dummy battery and install it using a similar slot for the cable, something I've previously done on a camcorder for my son. I didn't realize that dummy batteries were commercially available but will certainly make use of one now.

Hi Dave,
clever modification, I'm sure this will be of use for other microscopists!

This is the one I bought Tom, and I guess that Amazon.Com, over there will have the same, or similar.

Good job modding the camera to run off the mains.

I have been buying the dummy batteries and then wiring them up to compact, desktop switching power supplies. Here is an adapter I found by searching AlixExpress for "Canon 4000D dummy battery". Three months ago, I bought the variant for an Olympus Pen camera, from the same manufacturer, Ring Team. The gold contacts on the two I have, still look fine, with no sign of underlying oxidation.

A friend got a bad shock from an inexpensive aftermarket iPhone power adapter he had bought from Amazon. I took it apart and showed him what had happened. Since then, neither of us has skimped on power adapters. Lately, I have been buying medical grade power supplies which are designed and tested to never be "surprising", even if you are wired up to them. They have only cost a few euros more.

Thanks again Dave. Yes, Amazon Canada has exactly the same unit, except for the power plug of course, available at what appears to be an equivalent price, and even offers free shipping with Amazon Prime, so I've placed my order!
