shooting with lens detach? posible?

Hi guys.

Is it possible to shoot with no lens?
The camera just say no lens everytime I removed the lens. It wont let me shoot
I am trying to shoot some light leaks effects.

Thanks!

Ah nvm it can work s in video mode.
Just cant shoot still.

can you help us out with what camera you are using?
Have you tried in manual mode?

Depends on the model. I can do pinhole shots with no lens with my 400D but a Sony DSLR wouldn't let me.

Would think there is a way. Have not used it yet but have an adapter to hook my Canon to my telescope and it is nothing more than a metal ring with the proper mount connections on each side but no electronic connections so would think the camera would not identify anything was installed.

Do you have a 1.4X or 2.0X extender or a macro ring that you could try without a lens attached?

As others have mentioned make sure you are in manual mode. That reduces the required feedback from the lens. It can be done as there are users out there who freelens, taking shots with the lens detached from the body slightly to alter the focal plane.

For Canon EOS DSLRs you can actually set the camera to Aperture priority, and the camera's metering system will set the necessary shutter speed. This applies to both Free lensing, and using a un chipped mount converter. The only difference to using a normally attached EF mount lens is that you cannot then change the aperture value. The aperture recorded in the EXIF data will normally be f/0.0.

Shooting without a lens...what would focus light onto the sensor?! You need something with optics in it, whether a microscope or telescope or even a tiny pinhole in aluminum foil which serves as virtual optics to project an image onto the sensor...or else you are shining small beams of light directly onto the sensor (careful shining a laser!)

One thing you can do to fool the camera is to merely mount an adapter ring with AF confirmation chip, even with no lens in front of the adapter! But in M mode you do not even really need that.

assuming you have the 6D that we were discussing in another thread, my 6d will release the shutter (take a picture) in every mode, including automatic.

but the following is true, you will get nothing but a blurred blob.

Freelensing, for those that have not come across it, is done by (usually) hand holding an unmounted lens in front of the camera. The added extension will generally make for quite close focusing distances, so you are unlikely to see infinity focus. Also the fact that you are not necessarily going to keep the lens perfectly aligned, you are likely to see both shift and tilt effects, at least within the available lens projection circle. Doing freelensing with lenses designed for larger formats can help with all of those things though. A lens with manual aperture control is also useful.

that sounds interesting. I have some medium format lenses i might mess around with using that technique.

but, the OP did say "Is it possible to shoot with no lens?" so, I at least, was just going on that bit of information.

My 6D will trip the shutter in any mode with no lens attached. I'd try my film body, but it has film in it.

Yes Canon EOS cameras are quite good in that respect, and will function fully apropriatly in any exposure mode. Some other makes are different. As I understand it for example Nikon cameras in this situation will only work in Manual Exposure mode. Other makes may have other restrictions.

Well if the question is if it's possible to take a picture without a lens attached, the answer is yes. On my Canon, there's a setting in the menu for disabling or enabling picture taking with the lens off.

My Elan IIe would work with close to no lens. I would often turn a normal lens around and just hold it against the body. This was good for pseudo "macro" and I used this technique regularly for close ups of machinery failures. I later discovered a reverse mount adapter which gave me improved IQ since the lens was properly centered relative to the film plane.

I'll have to see if the reverse mount adapter still work with my DSLR.
