Hey all,

I've been using the EOS-R for almost a year and now my only issue with the camera is being unable to focus while using DOF Preview. I've used Canons DSLRs in the past and used the feature frequently. I find it extremely beneficial being able to see what is exactly going to be in focus before I take the photo.

I'm aware that you need to bind DOF Preview to a button, and I've done that. However I'm not able to focus while holding the button down. Making it a really clunky process of repeatedly pressing it as I make adjustments to the focus. Is there anyway of keeping the lens stopped down while focusing?

It works in video mode, so I don't see why this shouldn't be available while taking photos. I am aware that the EOS R keeps the aperture fully open to make it easier for AF, MF, Exposure Simulation, ect...

Any help would be appreciated, thanks guys!

Just do it the other way around:

1. Half press to focus

2. While holding half press, press dof button to verify and adjust if necessary.

3. Fully press shutter button.

That's what I do. It's not bad that way.

So you're able to adjust your focal point while holding down the DOF button?

Yes

Well that's fantastic to hear!

Just to clarify, you're using an EOS-R and RF lenses correct?

What button have you bound DOF Preview to?

I use the back focus button as im not a back focus button user anyways
