EOS 850D How to use mechanical shutter when using LCD screen

[conor64]

Hi everyone, I'm hoping someone can help me overcome this issue on the Canon 850d.

I like using the LCD screen when taking my photographs at low angles as I can use the articulating screen to my advantage, I recently picked up the Canon 850d and I much prefer using the mechanic shutter which can only be used with the viewfinder and not the LCD screen. Is there a way that I can disable the electronic shutter and be able to use the mechanical shutter on the viewfinder and the LCD screen? Or is there a way that I can display the viewfinder onto the LCD screen?

Thanks in advance.

Conor64,

I have the T8i (which you refer to as an 850D), and to the best of my knowledge, it doesn't have an electronic shutter.

Do you have the User's Manual? If you haven't done so yet, I'd strongly encourage you to download the pdf version. Using a pdf reader like Adobe Acrobat Reader, you can use the Search function to find answers to specific questions.

Do you know how to enable the touch shutter function on your LCD screen?

You can switch back and forth between viewfinder shooting and Live View shooting by hitting the Live View button, but you can't do both at the same time. It has to be one or the other. Do you know where the Live View Button is located?

When you are in Live View, you can take a picture with either the shutter button, or by touching the bottom right hand corner of the screen (if you've got that enabled)..

Live View does show what is in your viewfinder. It's just projected on your LCD screen.

If you have any other questions about how your T8i operates, I'll be glad to help if I can.

Steve1,

I had seen online when googling about the electronic / mechanical shutter after doing some test shots in both shutter modes. The viewfinder uses a mechanical shutter at 7 FPS whereas the LCD screen uses an electronic shutter at 7.5 FPS. I know that some people have complained about the rolling shutter when using the electronic shutter as it somewhat slightly distorted their images. I’ve attached a screenshot that I found on a website regarding the type of shutter used, I had checked a few other websites and had found the same information.

The camera did come with a manual of some but it really only showed how to turn the camera on/off and how to use the different drive modes etc.

Conor64,

I think there is some confusion here. Can you provide a link to what you saw online?

The EOS 850D, also known as the Rebel T8i, DOES NOT HAVE AN ELECTRONIC SHUTTER. I don't know that ANY DSLRs do. Mirrorless cameras, though, DO have electronic and manual shutters.

No, you cannot view thru your viewfinder and on the rear LCD (Live View) at the same time. Viewing thru the viewfinder requires the mirror be DOWN. Live View requires the mirror be UP. It's one-or-the-other.

The mechanical shutter is used with both viewing methods.

Here is a good article I just found that discusses mechanical, electronic, and electronic front-curtain shutters and how they affect picture-taking.

Rolling shutter is an electronic shutter phenomenon only. It does not apply with mechanical or EFCS shutters.

Normadel,

This is the link to were I found the information about the shutters, you’ll to scroll down to the title Front of the Canon EOS 850D.

I had read online that the LCD screen uses an electronic shutter and the viewfinder uses a mechanical shutter.

I have also attached two images of the shutter. The mirrored shutter image is showed when using the viewfinder and the other image shows the shutter when the LCD screen is being used.

I was using a Tamron 70-300mm on a tripod while doing the test photos and when I had focused on areas they were a bit out of focus. I will attach an image taken on the camera on the next reply.

This is a screenshot of a RAW image taken at shutter speed 1/1250, f8, ISO 1000. The focus point was put onto the tree in the background, it may be just me getting used to the 850D from the 500D.

This is another image taken later in the day, shot at 1/1000, f5.6 and ISO 2000. I am wanting to use the Tamron 70-300mm for mainly sports.

The EOS 850D / Rebel T8i does not feature an electronic shutter capability. 

When you look through the viewfinder the camera drops a small mirror down behind the lens and in front of the image sensor, this mirror redirects the light from the lens up and in to the viewfinder. It will do this even if you remove the camera battery.

To use the display on the LCD screen, the mirror needs to be moved out of the way - like it would be for taking a photo with the viewfinder - and the sensor uncovered by the first shutter curtain - there are two. Canon calls this Live View mode. Now the electronics of the camera continually read the image from the sensor and display it on the LCD. When you take a picture the camera doesn't need to move the mirror, but just needs to move the shutter curtain to end the exposure. If it's not moving the first curtain, then you can say this is first curtain electronic shutter mode, but you have no control of t this. However if the camera has a Canon Speedlite on the hotshoe, or the flash is raised, the camera will close the 1st curtain before starting the exposure since the first curtain is used to trigger the flash, this could be your trick to get "mechanical" shutter mode in Live View. With live view mode there is no time needed to drop the mirror between frames so the continuous shooting speed can be fractionally faster than when using the viewfinder, hence 7fps vs 7.5fps. There is also a slight difference in the sound coming from the camera as it moves shutter curtains and mirror while using the viewfinder vs only moving shutter curtains when using the LCD screen.  

[normadel]

"For example, we made high-speed 7fps sequences (7.5fps when using the electronic shutter) using a best-in-class UHS-I U3 card and the Canon EOS 850D managed around 55 RAW and JPEG shots before it stopped."

Well, this is an example of a reviewer not knowing what he is talking about. Where he says "electronic shutter" it should say "Live View" mode.

P4pictures explains it well.

conor64,

Here's a pdf version of your manual.

You can either bookmark it in your web browser, or save it to your hard drive and use it offline by using Adobe Acrobat or some other pdf reader.
