I've moved this to the meetings section - I'm sure it will be of interest to anyone who's closer.

is not to convert a lens to K mount. It is to convert a K mount body into a screw thread body so that screw mount lenses can be used on it.
This was to allow those who needed to upgrade/replace their Spotmatics with something newer to continue to use their old lenses. (Prior to this there was a similar adapter to allow the new screw thread lenses to be used on the older Asahiflex bodies.)
The technique is to fit the adapter to a lens and mount it onto the camera. The adapter clicks into place and the lens can be removed and replaced with another as and when required. The Pentax Adapter K may seem expensive, but is beautifully engineered and will not jam into the bayonet.
When you want to remove the adapter, release the catch as descibed by others and, holding the camera pointing down just rotate it until it drops out into your hand.
The catch is needed to ensure the lens does not become detached in use.

However, your lupin is largely out of focus, even if some parts may be approximately in focus.
Is the objective of this thread to just wind people up? If so, why? If not, what is the objective?

Competition standards use 1400x1050 pixel files, but visiting speakers invariably bring widescreen laptops. The still image quality is paramount, but the projector still needs to handle a normal wide range of uses.
It strikes me that therefore we need a 1920x1080 projector, but most of these are marketed as "home cinema" which may or may not be suitable for our purpose.
Does anyone have any insight into this that would help in choosing the right projector?
