Does the LP-E6P help the R5's Video Record Time? - EOS R5 Tip 86

[@sweet_tooth]

I've been using burst mode for photographing birds. Typically, I use a short burst of much less than 1 second. Time between burst varies greatly. Also, auto focus (animal eye-tracking is enabled). As for test conditions, I would opt for a controlled test scenario as follows: 1) Use the fully electronic shutter to avoid wear and tear to the mechanical shutter mechanism 2) Disable auto focus to limit the impact of a specific lens 3) Run bust mode continuously. Perhaps using a small JPEG so that the buffer limit is never reached. 4) Continue the test until the battery level eaches the 50% burst rate theshold and compare the number of still shots required for each of the 2 battery types

Thanks for this!

[@saurabhss5184]

It would be great to know if the battery affects stills too. I believe a more controlled setting with autofocus disabled would be better than autofocus enabled for easier comparison. Still not quite sure how I'd go about designing the test regarding the burst rates. A very interesting question indeed.

[@garyrowe58]

First off, if the standard video cases come out equal, then the difference - if any - would be at the heaviest load; therefore, auto focus would be a must for me. And, given that the drop to 9.2 fps is a real life change to operation, I'd certainly think that should be the cutoff point.

It does work on R5C i am happy shooting with them

[@PointsInFocus]

Yep, there are big gains on the R5C in video mode. The E6P's are a definite win there.

Can you please tell me why my one exposure is getting darker and one is accurate even on All manual settings under constant lighting condition? I am an R5 owner

[@PointsInFocus]

The only thing I can think of off the top of my head is to check that you don't have auto exposure bracketing enabled. (Shoot 2 menu page Expo.comp./AEB)

@@PointsInFocusalso can be a sync thing with LEDs.

[@PointsInFocus]

@jacy123, yes, that's certainly a possibility too. Though I would also expect flicker to end up being more random than one good and one bad. Then again, I've never been good at psychic debugging, so I kind of just go with what comes up off the top of my head that best fits the question and hope that the OP comes back and provides more information.

Hi does the new canon battery works to power 8k 60 on Canon R5C ?

[@PointsInFocus]

Based on my testing, you get more recording time, but the other limitations (e.g. no AF) still apply.

[@magnus547]

Just a couple of notes: The Original R5 downsamples from the 8K if you choose High quality for its for 4k 24 and 4K 30, which is exactly the same for the R5 Mark II. The R5 Mark II does not over sample the 8K in it's standard 4K recording modes.

[@PointsInFocus]

I'm well aware of all of that. Though I'm not quite sure what point you're trying to make here. For starters, I didn't compare the R5 and R5-2, I compared it to the R5C. Since I was talking about performance changes with a new battery in old cameras. Moreover, the R5C did see a significant increase in record time with the E6P; the major point I was looking to see if the R5 also saw. I chose the resolutions in question specifically to minimize the number of tests I'd have to run (and the resulting number of deep power cycles on the batteries) while getting the most data I could out of them. On the R5, 4K standard and 1080p both use about the same amount of power, so if there was a change in run time when shooting in 4K SQ, we would also expect to see something similar for 1080p as well. Likewise, 8K and 4K Fine both use similar power and have similar run times. Therefore a change in 8K record time is a reasonably good predictor of a change in 4K Fine record times as well. Given that the tests resulted in no change in record time with the new batteries, I deemed it pointless to do any more video record time tests.

If we're talking about the R5MkII then forget about shooting FCS just test the battery with Electronic Shutter, which might even be the most realistic way for action shooters to use the camera.

[@PointsInFocus]

We're talking about the R5, not the mark 2. And on the R5 there's no point in testing with the electronic shutter since that's not frame rate limited by battery power level.

[@budthecyborg4575]

@@PointsInFocus Whoops my bad.

[@PointsInFocus]

No worries.

[@budthecyborg4575]

@@PointsInFocus So I assume you are confirming that in ES mode the regular battery powers the camera at maximum burst just fine. That is interesting to see the choice of shutter mechanism is enough to overwhelm the battery.

[@PointsInFocus]

Keep in mind, in ES mode the camera is basically shooting video but saving the frames as stills. The ADCs are in 12-bit output mode, and the aperture stays stopped down (except in some rare circumstances), and metering and focus are measured at the stopped down aperture setting. So there's not a lot going on power wise other than the sensor read and AF drive. In FEC mode, the camera is cycling everything like a traditional camera. Stop down the lens, reset the sensor (this is the electronic first curtain), make the exposure, close the second curtain, read and reset the sensor again, open aperture, open the first curtain, measure focus and exposure, drive the lens, remeasure focus and repeat.
