Well crap I did it.... bye bye 6D... hello 5D3!

Say what you want but the hesitation is there. It's not in servo mode but in one shot it is. Try it. Compare it. Throw the lens to MFD then focus on something in one shot mode. NO half press... just mash the button all the way down and do it several times and take note of the time it takes from the time you press the button to the time the shutter goes off.

Then do it with any other body.

6D has lag. Others dont and I find it annoying as hell.

I've never noticed... because I always wait until the camera achieves focus before pressing down on the button. I don't want to tempt the camera to do something stupid.

Best of luck with your choice Talley, hopefully you enjoy your 5DIII, and all those now in focus shots !

to the original poster, you made a good choice. Ive had my 5DIII for a few months now. I came from a 5DII and dealt with the center point issues with that, loved the camera. I have a 7D and still use it but have never LOVED it. I had a chance to use both the 6D and 5dIII before buying one, I knew from the minute I used the 5DIII there was no going back, the focus system is a pleasure to use. The images are beautiful. That said to be honest I love my 1dIII and get more keepers from that camera than any other camera (including 5dIII) that Ive ever owned, had it been 18 megapixels id have never moved up to full frame. I'm sure you will love the 5DIII, having used a 6D I was amazed at the ease and the keeper rate of 5DIII in comparison, you wont regret it

But having the camera focus once and beep on lock, and then wait for you to press the shutter button further means that your reaction time is added between the focus lock time and the time when the camera flips the mirror to take a photo. This can matter a lot if shooting a moving object.

With servo, the camera can continue to track focus while it waits for the shutter button to be pressed fully.

First off NO camera should ever beep on focus lock. That is the stupidest thing ever. I'm at my kids stuff all the time and sounds like a damn disco with all the moms and their rebels going beep beep beep beep beep beep beep beep TURN THAT CRAP OFF.

Ok now that I got that out. Sometimes I'm in a hurry and I'm in one shot mode like during a birthday party and blowing out the candles and such so I'll mash the button all the way down in an instant but it hesitates to lock focus where any other camera I've had focuses and snaps the shutter off immediately.

Now I know I can work around this by going to back button and being in servo and such but I shouldn't have to because none of the other cameras do this.

Seriously it's my biggest pet peave with the 6D.

Sorry Talley, but it sounds to me like you're saying saying other cameras have instantaneous focusing (regardless of lens being used) and the 6D doesn't. What am I missing here?

Step three steps back and read "focus confirmation" then instead of "beep" and focus on the concept.

My post was about the difference between waiting with the button half-pressed until focus confirmation and then spend time to react to the focus confirmation - compared to having the camera take the photo as fast as the camera thinks it has locked focus. A difference that matters when the subject is moving.

Its for this reason that I always use BBF (beep off mind you!). If I've already locked focus and am waiting for the moment I don't want to be stuck with my finger half-pressing the button. Not to mention if I already have my focus set, and feel like I need to meter again I am not forced to wait for the camera to lock on focus again.

I also see no lag when using bbf

Not instant focus.

The time from focus lock to shutter actuation.

Sorry, you're saying from the time you acquire focus there's a lag to the actual shutter release?

Yes. Here is my original thread about it some time ago. I thought it was the superimposed display but I think not. https://photography-on-the.net …/showthread.php​?t=1305868

I just took some video with my phone THROUGH the viewfinder of my 40D vs. 6D.

I shot this using a tripod, ONE SHOT MODE, center point AF, 135L. First bit is the 40D and the second is the 6D. Excuse the orientation I did this in a hurry.

And if you think I"m crazy I slowed it down to 15% speed so you can see it for yourself. Here that video is:

Trust me... there is a delay. It's the camera, not the lens. One shot mode only. The delay is not there in servo. It's annoying as hell.

I suggest anyone with a 6D and any other camera.... rebel, XXD 1D or anything compare for yourself. Throw the lens out of focus and MASH the shutter all the way down and compare the delay from the blink to the actual shutter actuation.


I've noticed it from day one.

This doesn't take away the fact there is a few other perks for the move to the 5D3. I"ve made the 6D work and I can make it do pretty much everything I want it to do it just takes longer than a 7D/5D3. I want faster controls, faster AF selection, faster FPS, faster one shot shutter actuations... etc.

The 6D is a great camera but it's been "slowed" by canon in many departments. Hence it's price point.

What Talley is talking about is what I discussed in my thread last year.
Basically, the 6D, in one-shot mode, has an odd "hesitation" when auto focusing. There is a short hesitation after half-pressing the shutter but before the AF starts reacting, and then another short hesitation when it confirms focus. Now, I know probably most cameras have this except some cameras do it very fast and the perceived "hesitation" is so short, we can't really feel it.
But the 6D seems to take its time in one-shot mode. Not a bad delay, but it may bug certain people.

In AI Servo this hesitation is absent, while AF accuracy is virtually the same.

EDIT: I started typing my post about 30 min ago and got sidetracked with something else... That's why it looks a little out of place.

That's cool Talley...if you want it because it's bigger and heavier that's the only reason you need!
