10 frames per second
I have recently upgraded my underwater camera system, from a Canon EOS1DsMKII to an EOS1DsMKIII in a Seacam housing. Of course, the marquee advantage of the 1DsMKIII is the 21 megapixel full frame sensor and the extraordinary detail and color the 14-bit processing reveals. The files truly are stunning, but one of the coincident advantages to housing this system is that the 10 megapixel 1DMKIII is exactly the same size, and therefore fits in the same housing.
This creates multiple advantages:
1. A less expensive back-up camera.
2. A 1.3 crop factor on the sensor when a different perspective on the same lens is required. I especially like the wide angle field of view of the 15mm fisheye and 14mm wide angle when used on the 1DMKIII.
3. The 10 frame per second capture rate is a powerful tool for certain dive related imaging scenarios, like the giant-stride series shown here.
Admittedly, high res generally trumps frame rate on continuous shutter for most underwater applications, but the versatility of having two significantly different tools fitting in the same housing is very powerful.
