EOS Bodies / POLL: Price of 5Ds
« on: January 31, 2015, 07:11:03 PM »
My guess is at $7,5K for the 5Ds body. Since it is going to be announced in a week, it will be nice to go back and see who guessed correctly. Sorry no rewords  ;)

EOS-M / Idea on how to eliminate the mirror and still have a SLR design
« on: January 29, 2014, 03:27:32 PM »
I was looking at the sensor and noticed that it is very reflective, so I thought that maybe it could be used as the mirror.
Basically if the sensor was mounted at 45 degree angle and reflected the light up into the viewfinder during focusing and when the shutter released button was pressed it would swing down to 90 degrees to take the picture. The sensor would have the DPAF from the 70D for focusing.

The shutter mechanism would have to be relocated forward, maybe something like a leaf shutter just after the mount.

Possible problem would be vibration from the sensor pivoting into vertical position.

Has anything like this been tried before?

Lenses / Making a perfectly sharp lens corner to corner idea
« on: December 30, 2013, 03:52:24 PM »
I was thinking that a FF lens used on crop camera is sharper in the corners because it only sees the centre of the lens.
The lens designers could make a lens that has a much larger image circle (maybe 1.5x the size of FF), this would make the lens' corners sharp at full aperture on a FF camera.

The drawbacks that I see would be the size (thickness and weight) of the lens, but ignoring that why is this approach not taken?
