Wondering if anyone else has experienced this, the camera is taking over a second to record images, even on High speed continuous shutter I can only take one shot at a time, the camera reads "Busy" for over a second and will not take another shot until the Busy indicator turns off. I wondered if it could be the CF card so I put it into my 7D Mark II and it worked fine, removed the batteries to reset the camera, still no luck.

So..... has anyone else experienced this problem?

Do you have the lens distortion corrections and such turned on in the camera? If so, turn these off then everything should work fine.

Your camera is basically a small computer.
Things that will slow it down:
Having too many things set to do something at the same time is the number one cause, just like with your computer.
So if you shoot RAW and have it set to record to only one card that will lessen the load.
If you shoot JPEG with a bunch of things set to "get it right in the camera" that will slow things down.
If you are shooting RAW+JPEG with all those settings for the JPEG it will get even slower.
If you have it set to record to both cards for a backup then it will get even slower.
If you are shooting in batches that of course will slow things down while the camera empties the buffer to the cards.
If you have it set to review the image for a long time on the rear screen that will slow things down.
I don't remember if Canon's have a feature to verify both files are the same when you have it write to both cards or not, but that will slow things down.

If you have all or multiples of these things set then you will slow things down a lot.

I have a recommendation for you to try. (I'm good at thinking of things for other people to do, 34 years as a classroom teacher. Used a lot of four letter words also. HOME WORK) turn off wifi and GPS until you finish this
1. make a list of all your preferred settings. If you don't have a checklist Murphy says you will forget one or more, probably important ones too.
2. go into the menus and reset everything to factory default, do this on the custom setting also, they are separate. Then shoot some shots to see if things are slow or fast, if slow, call Canon support to arrange for the camera to visit the service center.
3. If it is not slow you now take a good setup list like the one from Photography Life http://photographylife.com/recommended-canon-5d-mark-iv-settings and go down the list setting things. Mark your list of settings as to which you do differently but don't change anything yet.
4. take some shots of anything the way you normally do and see if it stays busy a long time.
5. if it is slow, call Canon Support and find out what they say.
6. if it is not slow then go to your list and change settings one at a time, do some test shots (that includes bursts if you normally do bursts) to see if things slow down
7. keep doing this until you find the item/combo that is slowing you down or you have all the settings the way you like them
If you get all your settings and it hasn't slowed down that tells you that something else was set in a way it slowed things but the reset to default got rid of it.

Make and keep a list of all the settings so you can do a manual reset if anything gets changed in the future. Murphy says something will get messed up sooner or later. Esp if anyone else uses the camera or just plays with all the pretty buttons and dials to see what happens.

Oh, forgot one thing, do you use any of the third party "makes it do things the factory settings don't do" software like "Magic Lantern"? A setting there could really slooooooooooooooooooooow things down.

Last, turn wifi and/or GPS back on if you use them, if it slows down turn them off again and leave them off unless you absolutely need them. Besides your battery will last a lot longer.

Have you got any noise reduction function activated???

Turn off Distortion Correction and Digital Lens Optimizer. They're in the menu under "Lens Aberration Correction".
I had the same problem when I first got my 5DIV.

Pretty sure that one of RobertJerl tips and the Lens Aberration Tip should solve your case.

First time I experienced this was on my Nikon D7100, the SD card was cheap slow one. That seems to be not your case since you've tested the card.
Second time , was when I upgraded to my D750. Played a lot with settings and I've activated a lot of the "Auto/Enabled/High" settings like Auto ISO, Noise Reduction, Active D-light, RAW+Jpeg, and it resulted in slow rate. Seems like enabling lot's of in camera process tasks will have an impact on burst shooting. That's how I learned turning them on when in need.

Good Luck

I don't believe removing the battery will cause anything to be reset.
Format the card you use in the 5D4 for use in the camera.
Disable corrective actions as previously stated.

Best,

I want to thank everybody for their help, I have only had the camera for about 3 weeks and was a little freaked out that something might not be right with the processor. I turned off all lens correction and bingo, HS shutter is again functioning as it should. Feeling much relieved this morning. I only shoot RAW, no secondary JPEG images and I only use a fast (1066X) name brand CF card because the speed of the CF is faster than the SD's, brand new card purchased for that camera and formatted in the camera. At any rate thanks to your input I can rest easier this morning.

Blink...blink. Wow

The first lens setting answer was the solution of course... what is all this about?

RRS Loc: Not sure

Have you checked for dead pixels. I know that is not your problem but looking at different sites on YouTube yesterday I did see several not so good reviews on that camera all having to do with the new sensor. Have you tried single shot and what's the remaining charge look like on the battery. I was about to buy the 5DMKIV and the 100-400 II for my wife but now I'm sitting back to see how this all plays out.

Did it occur to you to call Canon?

The 5Dmk4 is stellar...This is an operator error problem. You would think lens aberration correction would be good but... it costs dearly in time if you expect the camera to possess the data at each frame.

I upgraded from the Mkiii was a huge jump in my opinion and I never looked back. 7fps and lightning fast, accurate focus, period.

Again the lens aberration correction setting is the known reason for the slow issue.

It is about finding and clearing up problems when you haven't got the foggiest notion what the problem is.
I have a 24 year old son who is mentally 5, on a good day. He loves to play with buttons, dials etc. When playing his train simulators on the computer he will get bored and click things at random just to watch what happens. From time to time I give him "Photography lessons" and take him out to shoot. I let him use a Fuji bridge camera, in spite of being told "Don't play with the dials!" He of course will if I look away "I'm fixing it!"
So I have a bit of experience at "un-fixing" computers and cameras with whacked out settings.
Now the first suggestion, later repeated by someone else who had experience with the same problem turned out to be right. That is great, esp for Blurryeyed, he did not have to go through this routine. But it is a process I am TOO familiar with. But it usually works. Twice in the last 3+ years it has not worked on my son's computer, I had to format the drive and reinstall everything, spend many hours over 2-3 days downloading all the updates again, then set up everything the way it was so he could play with trains again. I hope that doesn't happen again soon, the large baggie with all the disks, setting lists, passwords etc got "moved for safe keeping" by Mom. Who doesn't remember where she put it. I will assume it is between the front and back wall of the house somewhere, but don't want to put on my Indiana Jones hat and conduct a dig to find it. Yes I tried an external hard drive with Acronis doing regular backups. He played with the settings on that too, and disconnected it a few times. So I took it off and now use the drive to store backups of my photos and my wife's desktop's files.

It called growing pains. The 7DMKII had some problems when it first came out. I waited and did buy one about 1 year later. I was ready to pull the trigger on the 5DMKIV but have seen enough that I will wait. When Canon is advised that there's a problem on their site and 5 minutes later it's taken down, you have to wonder. I think the 5DMKIV shows some improvements over the 5DMKIII but $1,000.00 better I don't know, time will tell. Enjoy your new camera, there may just be a very few that have problems. As a result the 1DXII is looking better, for me anyway. I do like the 30MP but for BIF 7 FPS is slow after the 7DMKII.

I would check the write speed of the SD/CF card. With higher resolution cameras, the additional information will take longer to write. Used to be that using a class 10 would be sufficient but then the makers started varying the speeds to sell cheaper SD cards. The class really doesn't indicate the speed but the potential for speed. Also, when looking at the transfer rate, you want the highest write speed you can afford. Read speeds can - in some cases - be twice the write speed. Great when coping pictures off the SD card but your camera needs greater speed to write the pictures.

My suggestion is at least 120to150 mbs (also known as 1000x) . These cards typically have a good balance between price and speed.
