I got the new Canon EOS-400D, the Tokina 10-17 Fisheye lens as well as a new focus light Fisheye FIX LED 48DX.
For the Canon EOS-400D, I had to do a slight adaptation into my Sea&Sea housing. The fit is perfect and the large screen is a big advantage underwater. The adaptation does not have any impact on the camera which can be easily retrofit for the EOS-350D.
The Tokina fisheye lens has the advantage of focusing extremely close and of keeping the corners sharp underwater (Canon 10-22 does not provide such results). I was able to use the zoom ring for the Canon EF-S 60 with a small adaptation.
The Fisheye LIX LED 48DX has the advantage for providing a powerful light and at the same time has the flexibility of increasing or decreasing the light power with the twist of a simple knob.
While my latest pictures were already taken with the EOS-400D, the Fisheye LED is still to be tested.
I will post some pictures on the adaptations made soon.
