I just did a test with my 5D Mark III.   I find Mr. Cable's claim that putting an SD card in the card slot slows down the CF card.  Groundless.

Infared - his claim is not groundless it states so in the manual as I posted earlier today.  You don't state which Record mode your are on.   "Standard" and 'Auto Switch Card" have no effect with SD card in place however "Rec. Separately" and "Rec. to Multiple" will have a slow down effect see page 116 in the manual and or more detail on my earlier post.

This is a ridiculous article. Of course the speed drops off when writing to two cards. Canon states that is the manual. Cable clearly states "NOT" to put an SD card in the holder. If you do he says it will slow the speed of the CF card down.  That is CLEARLY not true. Only if you have the camera menu set to multiple write.   I knew this long before I bought the camera.  So where is the news?

This is misquoting me and says nothing either

Brian ....I have no beef with you, at all. My beef is with Cable.
 Cable says do not put an SD card in your camera it will slow down your CF card. Period.  It simply is not true.  It is an incorrect statement. He says if the card is there it slows the speed of your CF card. Not true. The camera has to be writing to both cards for that to occur.  WOW...I was writing to one card before with my Mark II.
Having the SD card as backup is a wonderful thing in my world. What a great extra feature on a great camera.
I think maybe Cable hangs out with Ken Rockwell.

Ever since it was released, the 5D3 appears to have received more criticism than praise. Canon in this case did make many people feel betrayed by cutting corners on a number of things, the SD card being one of them. This is not the first time they did this (remembering the AF on 5D2) and they will continue doing this. So are many other companies. Unless someone does it differently, by including all the best features on a second of the line product, we will have to accept the reality. I just hope Canon would not quickly abandon the 5D3 within a couple of years or so.

True enough.
 My biggest beef with the 5D II was the lack of bracketing. Same on the 7D..  Canon did a major firmware update and did not improve something that the camera should have been released with. Three shot bracketing is an embarrassment on a $2500 or $1600 DSLR. Simply an embarrassment.  Easy fix. My Micro 4/3's cameras put this to shame.  I certainly do not think Canon is perfect....but I can't stand incorrect statements or language which is clearly apparent in the article that sparked this discussion.

Yeh what Cable wrote "It turns out that the camera will default to the slowest card inserted." is wrong in my testing.

I put in a CF and SD card then set the camera to write small JPG to the CF and RAW to the SD, then I shot burst for 30 seconds and counted the shots taken.  Then I switched the setting, writing the RAW to the CF and the small JPG to the SD and repeated the test. The results were very different. Writing RAW to CF and small JPG to SD was much faster (burst maybe two to three times the number of shots in 30 seconds) than the opposite. So the situation is definitely more complex than "default to the slowest card inserted" in that scenario.

Now if you write the same size image (say both RAW) to both cards at once then the buffer cannot flush any faster than the SD card is written to, but that does not mean the CF card is being throttled.  It means the buffer is stuck waiting on the SD card. Put another way the CF card is all done but the camera's buffer cannot clear because it is waiting on the SD card. But I could see how someone might think that means the CF card is being throttled down to the SD speed, but from my observations that is not the case.

TLDR: CF and SD write rates are independent

You can't please everyone, there will always be critics.  I don't know if I'd call it betrayed, what were people expecting?  You only can put so many features on a 2nd tier camera, you have to draw the line somewhere.  That's why there's the 1 series and the 5 series.

I still don't see what all the fuss is about. Until the 1DX was released, with the exception of maximum burst speed, the 5DIII had better specs than any other camera Canon's ever made. And, except for a few meaningless megapickles of resolution and outstanding dynamic range as opposed to superlative dynamic range, it's better than any of Nikon's cameras.

What, you want the camera to give you an orgasm every time you release the shutter, too? Is that it?

Cheers,

Sorry Brian you were clearly ripped off buying the 1 series.  Better sell them and buy a 5DIII while you can.  :P
