Canon EOS 70D (RAW possibility)
« on: July 02, 2013, 12:32:07 PM »
Hi,

The Canon 70D is released!

http://www.engadget.com/2013/07/02/canon-70d-hands-on/
http://www.canonrumors.com/2013/07/canon-eos-70d-announced/

What do you think about Raw video? How are the specs? is UHS-i fast enough to write high speed video?
Where does it fit in the raw chart?

Thanks in advance! :)

I think it might be better for raw video because the buffer size should be bigger(for 7FPS) and I think card read/write speed gonna be faster than 60D which have speed at 21MB/s.

Notice that the SD card is actually a UHS-1 slot...very promising?

The 6D also has a UHS-1 slot... and it is limited to 50 MB/s.
6D | 24-105 f/4 | 70-200 f/4 | 28 - 35 - 50 - 50 - 135 |

Yes :) but thats already more mb/s then the Canon 600/650/700D ,.. ? :)

So a RAW would be a bit an improvement ...

It would be great if there was a hardware hack that you have to put a fake SDHC card in it thats an adapter and goes directly to a hard drive or a CF memory card that writes a lot faster! ;)

I thought the 650D and 700d also has UHS-1?

Yes, they have. And 650D is limited to about 41 MByte/s. And it doesn't matter if the SD-Slot is connected to a fast, fast card or any other storage device. Bottleneck is the controller chip. (Note to webmaster: Can we do have this as an animated banner or a popup or a sound file? <eg>)

Maybe the developers will find a way to manipulate the controller or there might be a safe and somekind easy hardware hack ... some day. Or not.

Ciao, Walter

Haha :D I have an idea!

You buy an old Canon 50D ... And then you solder the controller chip ? to the Canon 70D .. (ans lose your warranty) So you have a powerful RAW video camera with a lot of great features!  8)

Firmware doesn't support the speeds the "better" chips would run at.

I really hope the ML Team will be able to get ML on the 70D.
I have my 7D and I know the issues with the Dual Processor Problems and I will change my camera to the 70D and when there will be a ML FW and even with RAW capalbilitys that would be a dream worth some money :-)

Whish you luck to implement the ML FW to the 70D.

First post here! Long timer lurker though.

With the UHS-1 Card slot, the fairly large buffer on 70D, a fast 95mbs SDXC card, and some Magic Lantern wizardry, is it possible to get close to 1080p raw for at least a minute shooting?

I very much doubt that. First, no one knows if Magic Lantern will work on the 70D yet and second it will likely have the same SD controller limits as the 5d3 and 6d i.e. ~40MB/s. If it does have a better SD controller and ML can be ported it will be a winner for sure!

Raw Video should act as the 6D (70D has the same MPx and SD).

I have had my 70D since last Friday and man do I miss ML. I had used ML for over 2 yrs with my 60D, up until it was stolen. >:(

To those who have a 70D and a fast +90MB/s card: Maybe you could test the speed of the card slot and the size of the buffers:

Try shooting in high speed burst mode and count how many shots you get before it slows down.

Dude has done the work. There is a chart of results at the end of the video.
p.s. First post. I just bought the EOS-M and will be installing a ML build the day it arrives. I am saving up for the 70D. Even without ML it is the right camera for me, but with it, WOW! I am already walking funny because I have my fingers and toes crossed.

Empty buffer speed seems to be about 2fps which probably means 45MB/s like all the other recent Canon SD-card cameras.

This means it's too slow for continuous uncropped raw.
