Renaming 6D Files In Camera

I take (just a little) offense to your reference to the 6D's AF system as inherited from the 5D2. Not even close to true. I had a 5Dc (same AF as 5D2), and the difference is night and day. The 6D can lock focus with a slow lens in light the 5D2 would poop itself in. And the peripheral points of the 6D actually do work, as long as you stick to One-Shot. I can't count the number of times my 5Dc refused to focus IN BROAD DAYLIGHT WITH AN f/2.8 LENS while using a peripheral point.

One other thing. If you need shutter speed for that lacrosse match, I'd be happy to trade you my 1Dc for you 5DIII. The 1D does 1/16,000. I'll pay postage for both shipments.

Maybe you are right, but there's a bunch of sites out there stressing over the lack of an anti-moire filter on the 6D - thus making the video files not as clean as the 5D3.

If it has one, why are people make a big deal about Mosaic Engineering (in addition to, of course, Mosaic itself) making such a filter (for about $365) for the 6D? Is it because the filter is there on the 6D but just not as effective as it is on the 5D3?

For example, http://www.canonwatch.​com …ing-anti-aliasing-filter/

I read it on the internet. It has to be true...

Moire (which may or may not be wholly down to aliasing effects at the sensor) in video is a very different matter to shooting stills. it really depends on how they are taking data from the sensor to convert to 1920 pixel wide video. The 6D, and all of the 20-22 MPix 35mm sensors are pretty low resolution, with a similar linear resolution to a 20D, of about 8 MPix from the 22.5×15mm APS-C area. Because the 6D sensor is so large, 36mm wide, it means that you are taking the approx 5600 pixels from the sensor, and having to output that at only 1920 pixels wide. That is only 53 Pixels/mm, and that equates to a resolution of only 27 LP/mm. If you are not very careful in down converting the output from the sensor you will induce aliasing artifacts during the process. The latest MK II lenses from Canon are starting to deliver detail to the sensor at approaching 120 LP/mm, or 4.4× the Nyquist limit of the video output.

Lets face it even cinema 4K at 4096 pixels wide only offers a resolution 57 LP/mm and you would need to double it again to 8K to match the linear resolution of a 19 MPix APS-C sensor, which on a 36mm wide sensor will deliver 114 LP/mm, or about the limit of the best lenses. A 3:2 ratio 36×24mm sensor of this resolution will have approx 50 MPix i.e. the same as the 5DS.

Unless you are able to do 8K from a 36×24mm sensor you will always have to be very careful how you downsample the video stream. Actually the 22.5×15mm APS-C frame is much closer to the traditional 35mm cine format, which is a frame across the width of the film stock. I have seen suggestions that converting traditional 35m film prints to a 4K video format would be an ideal option for producing 4K video is sensible, 3:2 ratio 4K video is about 11 Mpix, a good choice for an APS-C sized sensor too, matching the old film stock.

OK. I am aware (have heard) that using the center point in low light on stationary subjects, the 6D is quite good. Maybe better than even the 5D3.

I know from personal experience that the 6D is NOT better than even the 5D2 in low light on moving subjects.

But, let's see whether the 6D's autofocus is closer to that of the 5D2 or the 5D3.

How many focus points on each? How many are cross-type? I think in that respect the 6D resembles more the 5D2 than the 5D3.

I am prejudiced by my use of the 5D2 and the 6D. I never had serious issues with the autofocus of the 5D2. I hated my two experiences (a few thousand shots the first time and a few hundred the second time) with the 6D but both occasions were of moving subjects on a low lit stage.

I do believe that, unfortunately for the 6D experience, the 6D was used as a backup to my 5D3. Whereas when I had the 5D2 my backup was the 5Dc. That probably explains it.

There were enough other reasons I could not bring myself to using the 6D as a backup and they are listed earlier above. I now rent a second 5D3 as a backup when really necessary.

We basically agree. The 6D and moving targets is not a good match. I bought a 70D to shoot my (grand)kids' athletic stuff with. All in all, since I am not focal length challenged, I think I would have gotten off cheaper if I'd bought a 5D3 in the first place. I do like having both formats, though. The 70D and 15mm gets me a lot more DOF at the dinner table than the 6D and 24mm.

Anyhow, thanks for all the replies, I'll stick with the IMG_ prefix until I can afford another 1 series body then ߘ

The 1D series isn't the only series to have this feature, just as an FYI. The 7D, 7D2, and 5D3 also support this, and there might be others.

Or simply get one of the numerous batch rename/exif editors and go nuts.
