After some setbacks and issues with the EOS M, I had an epiphany. We have two “old” EOS 5D cameras. Why couldn’t I just find a used housing for one of them? Sure enough, I found one for half price of what I would normally have to pay for a new case for a new model. I picked it up and have been finding used or on-sale lens ports to go with it.
This idea has several advantages as well as several disadvantages. First, the speed and responsiveness of the camera are incomparable to even a high-end mirrorless. Second, the pixel quality is one of the best in the industry despite it being a bit long in the tooth. The dynamic range is also much better.
The down side, though, is that the housing weighs eight million tons, and with all the accessories, it will be difficult to carry on a dive trip.
Well, I’ll just have to try it out and see.
