I would like to use this for BIF photography. I might need a bigger tripod and gimbal head though.
From the link Don supplied....
"The lens actually isn’t the main “lens” of the camera. You see, the Hyper Suprime-Cam is actually the new camera unit of the Subaru Telescope, the 8.2-meter flagship telescope of the National Astronomical Observatory of Japan. The Canon-made “Wide Field Corrector,” as it’s called, is placed in front of the giant sensor in order to improve the image quality of the main telescope lens.
The focusing unit of the camera (below) was developed by Mitsubishi, and is extremely precise: the 3-ton camera can be focused with adjustments as small as 1-2 microns, which is about 1/100 the width of a human hair.The camera was installed in late 2011 and was turned on in early 2012. It’ll be pointed toward the heavens in order to help scientists determine the distribution of dark matter in the universe."
