CANON REBEL T3 1100D "RELEASE SHUTTER W/O LENS

It is not possible to do this in Auto (green square) mode but will work in M or AV modes without the need to change anything in the menu.

Steve,

Thank you for the reply. Ishould have mentioned I am using SVBONY adapter on which I have attached a CA1 Extension Tube M42 Thread T Adapter and inside this tube I have placed an eyepiece .this complete setup is attached to my camera and then slid onto my Bushnell relector telescope so I can take shots of the stars.

I was researching too and I found the adapter you mentioned. The difference is that that adapter had the gold electronic conductors (7 dots) that mine does not. Its a bit pricey and I wanted to be sure before ordering whether this new adapter will actually solve the problem.

Thanks again,

Joe

Jethro,

Thank you for replying. I checked a few other manuals. Every other manual I checked seemed to have this setting in the Fn (other) menu- just not my model. I downloaded a pdf version of my model and did a complete scan for "release" just to be sure and the only thing I could find was " release shutter without card " i wonder why they make it this hard. Then I found an app called "lantern" that runs a firmware alongside Canon's firmware that adds features Canon has missed. But its risky as they warn the camera could fail to boot and they take no responsibility for that. They do not explicitly state that this particular function is included.

I wrote to Canon on Friday night lets see if they respond.

Thank you,

Joe

Ray, thank you for the reply. I did set the camera to M in the menu but it won't release the shutter without the Canon lens. Am I missing something?

I'll try anything you can suggest.

Thank you

Joe

Steve,

I found this link to a video. At 2:03 minutes, the host clearly states my issue:

The problem is that the  solution he provides just does not exist on the Canon Rebel T3 1100 d.

I cannot believe that Canon would not have included this some way or at least a work around.

you mentioned on your T8i you did not have the setting to enable shutter release w/o lens. How did you work around it?

Thank you,

Joe

Hello All!

To the folks who replied, Thank you very much for replying to my post.

I had a long chat with a very helpful Canon representative yesterday.

He confirmed first if all:

All Canon DSLRs have "release shutter without lens" functionality and if it is not a menu item then it works automatically.

He then had me Clear all setting effectively resetting my camera

He then had me switch the camera to all modes before the green box which is full auto and voila!! I could see through my telescope. Of course I had to use the T mount, inseet the telescope eyepiece in the extension tube, mount the setup on my telescope and I could see clearly.

I had a blast watching the moon and jupiter and its four moons dance around the moon all night.

Its amazing how is a span of a few hours the four moons around jupiter travel around jupiter and how our moon carries jupiter as it travels. Just so beautiful!

I called Canon this morning to send a special thanks to this gentleman. Following are the lknks he sent me during our call:

I was so impressed with the support I received.

We have a resolution thank you for permitting me to ask my question and to Steve, Jethro and Ray for helping.

I'm going to stick around this wonderful site and learn something.

Hi Steve,

Your analysis was spot on. Its working now. Thank you

Hi Jethro,

Yes it is Magic Lantern. For now I'm going to stay with Cacon firmware, I want to avoid adding variables so I do not get so lost there is no point of return.

Thanks for your help
Joe
