Need help on correct setup and settings using R7 body for astro. Have read manual and just can not get it to work. Last night had my 14 mm rokinon attached with adapter and had all correct settings 20 sconds, f/2.8, ISO 6400. Camera would not take image. What is set up on camera? electronic shutter, 2 second shutter, etc?
Solved! Go to Solution.

You need to go into the camera and set "shoot without lens". Then the camera will take pictures. This only works in the creative zone ie (M, Av, TV, P & Fv) modes.

what is the purpose of shoot with out lens? How does this make astrophotography work?

Your lens may not have electronic contacts to tell the camera body. That there is a lens attached. This is to protect the image sensor in the camera.

It’s not just for astrophotography. The lens could be used as a general ultra-wide angle lens. The Rokinon lens is a full manual lens; no communication with camera. Camera doesn’t know hat a lens is attached.

Hi Gents,
Demetrius is correct. The option is on the Custom Function Menu > Tab 4. Its called "Release Shutter w/o Lens". This should allow the camera to release the shutter with a manual lens. @Chief, I own this lens also, please post your pics in the share my photos section. 📸

That is a nice picture you can really see the blues and the greens in that picture. You should post that picture in the "Share Your Pictures" section of the forum.
