Hi All,
Recently i got manual extension tubes from my sony camera but when i attach them and try to click it says 'no lens attached'.
Am i missing something?

Will appreciate your advice.

Thanks

Did you get the tubes with just the mechanical attachment? Or do they have electrical contacts to connect the lens to the camera? If the former...your camera can't tell the lens is mounted. If the latter, check for dirt/oxidation on the contacts.

I have a set of cheapo ($9.99) extension tubes for Nikon. I don't know if this applies to Sony cameras, but I have to use them in manual mode with a lens that has a manual aperture adjustment ring. I have to open the lens up to its maximum aperture in order to see to focus, then stop down the lens to my desired aperture for the shot. Needless to say, the camera must be on a tripod for this method. I bought the tubes for extreme macro shots, so the tripod requirement doesn't bother me. The tubes will not work with any lens that does not have an aperture ring.

With canon if you set the aperture on a lense then press the dof preview button and the lens release button at the same time you can use that to set your aperture, take the lens off then put it on the manual extension rings. I have the ones with contacts that were £120 ouch I know but they work great. Not familiar with Sony but all my canons will fire without a lens attached maybe you're in the wrong mode?

Hi everyone,
Thanks for all your inputs, i have just mechanical rings (no electrical contacts). I am shooting in Manual mode (Camera Manual), my lens is AF.
The thing is its saying 'no lens attached' , i will try top set at max aperture. But i am not sure it will work as its not even recognizing the lens at all.

Thanks
