Hello. I recently bought my camera around 2 months or so ago but problem arose recently. Whenever I press the green button to meter in manual mode, it releases the shutter. It never done this before. I was wonder if anyone else has experienced this. I'm hoping I messed with the settings but I'm sure my camera is broken. Thanks.

Are you certain it is releasing the shutter, or is it just stopping the lens down? Have you recently changed from digital preview to optical preview? The latter results in the lens aperture stopping down physically, and it sounds as if the shutter is running.

Sounds like you need to set the green button to Tv shift:

Well, the shutter is releasing but not taking any photos. I am using a m42 lens so I don't believe it's able to stop down physically. Before, I press the green button in live view mode to meter in manual because it can't do through the lens metering. It never did anything to the shutter so I'm just very confused. I don't believe I touched any settings so it makes me believe it's software or hardware since it sometimes freezes the camera when the shutter releases part way after pressing the green button. Just disappointed since I only had this camera for 2 months and it's already bugging up.

It's on tv shift. The only time it doesn't release the shutter is if I set the green button to nothing. Very weird problem.

It is probably attempting to stop down the lens which is the sound you hear (a lever moves inside the camera). It doesn't know that the lens isn't a K or M lens that would need to be stopped down.

It is metering the scene - you should see the shutter speed be set to match the light level. As you wrote, no photo is taken.

Make sure that you're in manual focus mode, otherwise the shutter may "freeze" in case the image is out of focus.

Does it do anything if you use the green button with no lens mounted?

No shutter release without the lens on.

No shutter release without the lens on.

I'm thinking you're hearing the stop down lever moving. The camera should be silent when the green button is pressed and the contacts are not shorted, M42 lenses usually have anodized mounts and should not be shorting the contacts. What lens and adapter are you using?

With M and K series lenses all of the contacts are shorted, so it assumes it has control of the aperture lever. Do you have any M or K series lenses? Is the sound the same as you are hearing with the M42 lens?

I'm using a takumar 50mm f1.4 so a m42 lens with pentax brand adapter. I've been using this lens and adapter since I bought the camera and it never tried to move the stop down lever. It always just meter without any noise or movement of parts. It's firing the shutter like I'm taking a photo. I see the viewfinder blink like I took a photo.

Okay I think I figured it out. I've been tightening my lens down a little bit tighter recently so that the aperture number is on top of the camera. When I do this, I'm guessing it's shorting the contacts. So I have to loosen it slightly for it to stop doing what its doing. Now the thumb lever for manual/auto on the lens is covered by a part of the camera but it's working like it did before.

Is it suppose to stop down with a m42 lens or not? I prefer to have the lens tightened so the aperture number is on top and the manual/auto switch is assessable.

There is no mechanism in your camera to stop down an M42 lens. The lens is stopped down by a pin that is pushed out from within the camera, and no K mount camera has space for the push bar.
