Canon 5dsr shutter lag / delay

[upsidetriangle]

So I picked up a Canon 5dsr to be used only for fireworks displays and im having an odd problem.

Im in bule mode all manual setting and lens in manual focus.

Im getting shutter lag / delay on the second and all subsequent images until I let the buffer clear.

When I go to take an image straight after the last image you can hold the shutter down for maybe 0.25 - 0.5s before the camera will start to take the image.

The buffer is not full but it is transferring. This is with a slow SD card a Lexar 1000X 128gb but I don’t think this is the problem as the buffer is not full.

The lens im using is a Sigma 12-24mm f4.5-5.6 DG HSM.

I did some testing on my R6M2, 90D and 1100D and all work as i would expect letting let take photos as quickly as i would like until the buffer is full.

50 megapixels and slow card could be your problem.

As John noted, you need a fast card for this camera given the sensor size. 

But I wonder if mirror lockup or some other function is set.

If this was a previously owned body (likely since it has been our of production for some time), use tools menu tab 4 to clear all camera settings back to factory AND also go to the last tab of the custom functions screen and clear all custom functions.  These are two separate items and both must be done to reset any previous user settings.

I don't shoot a lot of photos with my 5DS R bodies because I use my 1DX III bodies for sports but I have shot quite a few photos with my 5DS and 5DS R bodies in high speed drive and there was no slow down in multiple image bursts because I never ran into the 12-18 shot buffer limit.

It would be unusual behavior but if you are using servo AF with moving subjects then it can be fine tuned where you move the "bias" between shutter release and image focus; I leave all of my bodies set biased to focus since poorly focused photos are of no use to me.  This adjustment is found in the second set of menu items under the AF2 tab.  But unless you are using a slow focusing lens with a moving object, this sort of delay shouldn't occur under these conditions.

The Lexar 1000X 128gb should be for them fast enough for the 5Dsr as it only supports UHS-I SD cands. I put in one of my Kingston Canvas React Plus 128gb cards a good UHS-II card with 300MB/s R, 260MB/s W. same behavior.

Also change from raw to jpeg in diffrent sizes and not change.

A factory reset and custom functions clear has already been done is did not change the behavior.

I tested high speed connection works just find.

I have the lens in manual focus im in single short and have ISO 100 and aperture f8 set.

What storage format are you using, RAW or JPG?  Do you post process photos?

What NR, noise reduction, settings are enabled, if any?Try disabling them.

Same for any lens or image correction settings.  If any are enabled, try disabling them.

Im in RAW and there will be some editing.

NR, noise reduction, ect all disabled no change.

“ Im getting shutter lag / delay on the second and all subsequent images until I let the buffer clear. “

I just noticed this comment.  Once you fill the buffer, not being able to take additional photos until the buffer clears is normal behavior.

[upsidetriangle]

Correct but the buffer is not full on the second image so why would i get the lag / delay on the second image.

You clearly stated that the buffer is full.  While the camera has two card slots, there’s only one buffer.
