The 20Da seemed to outperform regular modded cameras and also it worked as a daytime camera as well. It had a different firmware that seemed to reduce noise. I think there was something about the way the circuitry amplifiers cut in that reduced heat buildup in long exposures and reduced noise further. Like the amps were off until the exposure was complete compared to amp on as soon as shutter clicked in reg camera.

It also had a slightly different firmware.

It may also double as an excellent infrared camera.

I expect it to be a little bit better than what is generally expected here. The 20Da was the only DSLR camera that produced images approaching good dedicated CCD images.
