What, 64 bit images or process them on a 64 bit computer? That's not the same thing.

What could be the limiting factor is the software itself. As some of the functions were greyed out it sounds like you have an older version of Elements. Elements 6 doesn't allow image manipulation in 16 bits though files can be opened and resaved in another format such as a 16 bit TIFF.

As other have said it is better to work in 16 bits and do the final save in 8 bits if possible.

With Elements 6 you can change the bit depth in the Image/Mode setting. So transfer the raw file in 16 bit and convert it to 8 bit if you need to to work on the file.

I tracked some down with help from my local store down in Kent/Essex. Phoned up that store (Lakeside) and it is in the process of being transferred to my local branch. No hassle at all and thanks in advance to Jessops, so worth a try? Bromley and Bluewater in Kent were also showing stock.

It doesn't look to have the button to press to remove the lens as far as I can see. Bridge camera lenses are usually fixed so doubt that this would be an exception. Some comments on the American forum talk of using DA etc. lenses, not sure what has given them that idea.

I purchased one off ebay recently, see item no. 140635947261 (RJ Pentax PK PK-A AF DA lens to Pentax Q adapter with tripod mount aperture ring)

It works just fine. It allows control of the aperture - you set the aperture you want on the lens on in the camera and you twist a ring to close the lens down. Not sure why you believe it needs an extra shutter system, it doesn't have that and doesn't need it, the one built into the camera is all that is required. Results with a good lens are just fine and no issue with infinity focus.

I do find though that with all the extra hassle of setting it up and not having a proper viewfinder in real life it is much easier just to take the K-5 and be done with it! With all the extra gadgets space and weight saving over the K-5 is minimal and setting it up and taking the photograph is far from instantaneous. But it does work and to get a long telephoto equivalent without having to buy one could be useful in some circumstances.

I also purchased the Auto 110 to Q adapter # 200731862552 (pentax 110 lens PTX AUTO 110 P110 mount lens to Pentax Q mount adapter)
This works well with some 110 lenses such as the f2.8 70mm but not the f2.8 20-40mm zoom as with that one it doesn't manage to focus at infinity (although fine on the 110.)

Not a Pentax and not a lens cap. On enlargement it Looks to be a Panasonic camera with an ND or polarizing filter attached.

John

Not sure that's really correct. However worth considering that it was competing with the 40mm f2.8 'pancake' that was a popular kit lens with the ME and MX and the 35mm was close to that so it made more sense to add a 28mm rather than a 35mm. I suspect that before the 40mm was released the 35mm was very popular and given Pentax's market position at the time it sold in droves!
