p.1 #1 · p.1 #1 · 5d3-mirror lock up operation?


A couple evenings ago, I was at Kezar Lake, and decided to try an extended exposure shot. I had the camera on the tripod, and had the 16-35 canon lens. It appeared that I had packed my remote trigger release somewhere in my backpack, in a place that would render it unfindable. That was when I realized, I hadn't memorized where the timer release option was. Yes, this is a bit different than my old EOS film camera.

I did set the mirror lock-up and was shooting a manual exposure setting of about f-16 and 20 seconds (+/-, as I didn't memorize it.). When I released the shutter, I heard what sounded like the mirror lock up, but then there was no image recorded. I decided that trying to figure this out in the dark was going to just bring frustration.

Yesterday, I trie it in the kitchen, with a more normal exposure, and the same thing happened. If I release the shutter again, it shoots the image. So, what is that all about? With my old camera, it happens in one release of the shutter. The mirror moves up, locks, takes the photo, then releases. Do I have something set that I don't know about?, Like one of those hundreds of settings?

So, there is one for the stupid question books.

I appreciate the help though, regardless.

Cheers,
Dennis

First press locks the mirror, second press captures the image. Your camera is working normally. It allows the vibrations of the mirror to subside at your discretion before capturing the image. I believe if you review the manual, it will describe it better than I have, but with more words.

Enjoy the new body!

Paul has it correct!

I was pretty certain it was me. I just don't remember my previous camera functioning like that, so, since I read my manual twice and still don't remember half of it, I figured there was a 'me' factor involved. Thanks for setting me straight.

I am enjoying it for sure. This camera is mind blowing. The body, the glass. Incredible. What a fun journey this is going to be.

I hope to become worthy of my camera.

Mirror lockup is best used with a cable release. By simply putting the camera in mirror lockup mode without a cable release, you'll still end up with a shaky camera. The solution is to combine mirror lockup with a short self timer. The mirror will lockup first, then a couple second later, the shutter will fire.

Not to be a SA but why not just use liveview and the 2 sec timer to do long exposure shots if you don't have the cable release readily available?

Because you would need to read the instruction manual to learn how to do that, too...

Ah, well played.

Actually, as I said in my OP, I had read it, but hadn't memorized it. I'll work harder.

It is my understanding, and always has been, that locking up the mirror, cuts down on vibration induced by the mirror, not the operator. So, Live view and 2 second timer doesn't actually address that issue.

The Cable release was certainly the key element, lack of prior and proper preparation, indeed provided piss poor performance. I admit that. I haven't shot in 12 years, so, I am a little rusty. Now the question would be, if you use mirror lock up and timer, does it keep you from having to press the shutter release twice? That would preclude me from having to touch the camera again, there by inducing operator movement.

That was rhetorical, as I will gladly go re-read the manual, and maybe try it out.

That's the whole idea, you delay the actual shutter release by 2 sec, which is plenty of time for any movement you cause by pushing the shutter button. Again, the actual exposure will take place after the 2 sec have elapsed and you have to push the shutter button only once in the liveview mode. The mirror is up already from the liveview action. Yes, it is better to have a remote release since you can time it as want but if you don't have that cable release readily available, it will work just fine. I have done this many times, BTW and didn't encounter any issues.

Got it. You still have the vibration induced by the mirror though. This would or should then be done in conjunction with mirror lock up selected, assuming that can be done.

Dennis, the mirror is up already in the liveview mode.

Hmmm. Ahhh. Duh. I guess that would have to be. Welcome to digital nitwit!

Thanks for clearing that up.

In my experience, leaving the camera in live view heats up the sensor and lends itself to a noisier image as well as the occasional hot spot. When shooting long exposures on a tripod, I compose with live view, then switch to mirror lock-up for a cleaner image.

Yup. I have a cable release. Since I hadn't shot for many years, all my gear is new, including the backpack bag. It wasn't as organized as I thought it was and trying to work in the dark, brought that to light!

good point about sensor heat. I guess in that respect,like film, if it gets too warm, it's going to be a problem.
