Canon R6 I Electronic vs Mechanical Shutter

[sarahbearpatch]

Hi,

I have an R6. I love it but I don't know what the difference between electronic vs Mechanical shutter. It's confusing.

Additionally, I've been watching YouTube about back button focus and I think if someone has the time and patience, if you would be up to a zoom meeting, I'd really appreciate it. I learn best one to one and it's not sticking in my brain.

Thank you for reading this. I hope someone can help me.

Blessings,
Sarah

Additionally, I am confused on the Servo and one shot. I do have AF-Focus on. It drives me crazy sometimes because if I'm posing my subjects, it auto focuses while I'm doing that.

One-shot focuses once, and when it has achieved focus it stops trying. So at that point you can recompose or whatever, as long as you leave your finger on the button. Plus once it has focused on what you want, you know it's going to stay there and not jump to a different subject.

Servo constantly adjusts. I use this nearly all the time because there's hardly any reason not to. Even static pics of kids or whatever, they move... I move... why not have the camera update the focus all the way to the exposure.

I do switch to One-shot every now and then when there's the chance that the focus will hunt among eligible subjects at the wrong time.

If the camera is focusing by itself while you are posing your subjects, you probably have AF preview (I think that's the name) turned on.

Hi,

Thank you so much for the information! I appreciate you taking the time to write a thorough response.

I photograph people, pets, and NOT events. I do portraits. But *sometimes* I will do an event for friends etc. I just got a strobe and am learning to use it. I usually use speedlights with either my MagMods or softboxes.

Additionally, I am confused on the Servo and one shot. I do have AF-Focus on. It drives me crazy sometimes because if I'm posing my subjects, it auto focuses while I'm doing that.

Please feel free to send me an email at sarah@unspokenimagesphotography.com if you are willing to help me understand things. I'm a hands on learner or via zoom. YouTube is hard for me to learn because I have so many questions, which sometimes don't get answered.

Thank you again for your help. It was much appreciated!

Hi Sarah,

If you check out the previous reply, Anton provides as good an explanation as I ever could about the practical differences between Servo and One Shot AF. (I generally use Servo unless both the subject and me are completely static and I want the focus to be on a particular point).

I don't photograph people (only Karen - and her eyes are co-ordinated with my shutter, so she always has them closed... ), or pets and I don't use flash/ other lighting (plus I don't have an R6!) - so I suspect I'd have far more questions/ blank looks than good answers for you.

As you've seen, if I pick up a query on here and I have the knowledge/ time to answer, I'll generally try to help, but I can't offer one-to-one tuition (and the reality is, I'm as much at sea as the next person - my 'informed' replies are usually proceeded by the rustle of the User Manual and/ or copious on-line researching).

I'm pleased to have been of help to you - and I'll continue to chip-in where circumstances (and my limited abilities) permit...

I am partial to mechanical shutter mode. I believe, and I need to do the test shots, just been busy with family life, the electronic modes produce greater color noise across the image than mechanical shutter use at the same settings.

I have been using BBF a lot, however I keep my shutter button on half press AF-On. I find BBF really brings out all the strengths of AF Servo. I find better hit rate with fast moving subjects using BBF. The advantage used to be you could focus with BBF, take pressure off the button and then activate the shutter without refocusing. With the insane AF systems even the cheapest mirrorless cameras have I don’t think that’s a huge issue anymore. They all focus so accurately and quickly.

I think the joystick is more useful than the AF-On button. Give me the option between BBF and joystick I’d take joystick. I use it a lot to move my focus points or click it to choose a different subject. Very useful for wrestling photography a few weeks ago!

Thank you for your experience and thoughts! I appreciate you taking time to explain why and what you use it for. Again, thank you! Happy Holidays!

Sarah,

You raise two interesting but quite complicated issues - shutter type and BBF.

The link that Phil provided on shutter types is really good, but it shows how complicated shutter technology is. Most folks are not going to understand all the ins and outs after one read.

I have my R5 and R7 set for first curtain electronic shutter and I practically never change it. It is great for almost all the kinds of photography that I do. So one simple way to deal with complexities is to just pick a useful alternative and stick with it until there is an issue that requires you to change it.

At one of our local model shoots, one of the participants couldn't get his camera to work with the flash units there. It was a stressful moment because it was his turn and the model was waiting. It turned out his camera was on electronic shutter, and in that mode, wouldn't work with flash.

ES in burst mode can easily give you hundreds of exposures that you need to review later on the computer. It can give obvious rolling shutter effects, but also subtle ones that will be present but are harder to see right away. These are disadvantages of ES.

So unless there is a particular need, I would stay away from electronic shutter and use EFCS.

Back button focus was great for many of us with DSLRs, and I still use it today with my mirrorless cameras, but not all the time. If you are just getting acquainted with focus modes, I would just use the default, which is focusing with a half-press of the shutter button. That will serve you well most of the time, maybe all the time. If you discover a need for better control of focus in some circumstances, that's when you can experiment with BBF.

Once your muscles are trained for the normal focus mode, it can be very hard to get used to BBF. Folks will be surprised that the camera won't focus, until they remember it was set for BBF and they need to press that button.

Thank you for your thoughts and input. I will definitely explore the options! Happy Holidays!

Just wanted to update you. I took the shutter button off AF-On with half press. Now it just releases the shutter. I’m finding good results. However, as I said earlier, with the AF systems on mirrorless cameras I think it’s a lot of splitting hairs.

Let me address the BBF question. My wife and I shoot wildlife, birds and animals. BBF is particularly useful in our R5 and R7 cameras. We have the AF-on set for animal eye servo tracking so we can quickly acquire focus on the critter's eye. As long as we hold it down it will track anywhere in the frame. However, there are sometimes the camera needs a bit of help finding the subject, or we want a very specific point to be focused on. Then we have the button just to the right of the AF on button programed to AF using the center point AF spot. We can instantly switch between the two with a simple thumb adjustment. It only took a short while to adapt to this. In addition, having the AF separated from the shutter release allows us to acquire AF then use the shutter half press to adjust the exposure. Practice, practice and then practice some more.
