EOS R7 How to get full 30fps in electronic shutter mode

[jake82]

I have a brand new canon r7 with a canon efs 18-135mm lens paired with it, and am wondering why i am not getting the full 30fps shooting in the electronic shutter mode even though I have tried both high speed continuous + and high speed continuous modes. If you have any suggestions for me let me know. Thanks!

Jake,

It could depend on your shutter speed. If you're using a slow shutter speed, it could take longer to cycle through those 30 frames.

I’m using 1/1000, i think the issue may lie in the lens as it is a bit older.

Because the lens wasn’t designed for that level of performance.  The lens was designed for APS-C DSLRs with max frame rates of 3-10 fps.  No EF mount lenses are.

If you want to use the electronic shutter and 30 fps bursts, then I suggest you invest in RF mount lenses.

According to this page by Canon there are many EF and EF-S lenses capable of 30fps(including 18-135 USM and STM) so I don't see the need to advise(at least for this problem) buying RF lenses.

@pcs1 You do realize that most EF/ EF-S lenses max out at 12 FPS not 30 FPS. It’s a limitation of the lens’ hardware. The lens’ aperture cannot stop down fast enough for that. Or the lens’ AF motor is just too slow for it. Saying “EF-S 18-135mm” isn’t a complete name. They could be using the original Micro Motor version. Which can’t support that rate of shooting. Since the lens hardware in EF/ EF-S lenses is older. I’ve found most lenses aren’t capable of H+ shooting. The camera will blink the H+ icon in the EVF. Just using regular H shooting works fine. Also a lot of EF/ EF-S aren’t capable of really high shutter speeds. Certain video modes aren’t supported either.

Yes I'm aware but that's for mechanical/EFCS, I, as was the OP, was talking about ES.

See the table in the link I provided, there are over 35 EF/EF-S lenses supporting maximum continuous shooting speed. 

I agree the OP didn't specify which 18-135 so if it's not EF-S18-135mm f/3.5-5.6 IS USM or EF-S18-135mm f/3.5-5.6 IS STM(both of which are in the mentioned list) that could be the problem.

Mechanical Shutter is 12FPS. That was confirmed by Canon. But for EF/ EF-S lens max FPS varies with ES depending on the ambient lighting. The page you linked is NOT a guarantee that such a lens can get that exact FPS. Most of the time it’s less or sometimes more. This is more of a problem with EF-S lenses but not EF lenses. Since those were upgraded first before EF-S lenses were.

That's also true for RF lenses😃

That entire section of online documentation is poorly written.  It conflates the shutter modes and frame rates. It should only apply to the default shutter mode.  This screenshot is from the User Guide for the R5.
