Canon 1D Mark IV

 A short story of how my Canon EOS-1D Mark IV came to it's end

Went out one morning to take photos of  two professional fresh water fishermen they were pulling up nets that they had put there the day before  , A lot of water was splashing around and coming in the small (12 ft) 3.66 m dinghy apart from the splashing it also started to rain

All this was not a problem for the 1D Mark IV as it is sealed but not so for the 50mm f1.4 i was using,Well i  decided  to change the 50mm for the sealed Canon EF 24-105 L lens , Big mistake with wet  and greasy hands and standing up in the boat while doing the lens change i was left holding
the 50mm f1.4 in my left hand and nothing in my right hand the 1D Mark IV was gone slipped out of my hand hit the top edge of the boat and went strait to the bottom of this murky river.

We recovered it by dragging a weighted fish net along the bottom, Not a pretty sight  full of  water mud and small stones inside the mirror box.

Canon EOS 60D: Broken Shutter After 58,000 Actuations

The EOS 60D is one of the latest Canon models to support high-capacity SDXC memory cards, providing up to 2TB of available space, allowing photographers to keep shooting HD video and full resolution RAW and JPEG stills without changing cards. For better management of larger image libraries on the camera, EOS 60D photographers can add a rating of 1 to 5 to their favourite images, allowing them to be easily located and viewed on-screen. Once transferred from the camera to a PC, the tags can also be viewed using a number of image editing and management programs, including Canon’s DPP software.
