I got the tubes from AliExpress today. They are very nicely built and there is no play at all, even when using the three tubes stacked. They function as advertised (a Q lens mounted on the tubes will autofocus and be fully functional).

As everybody has guessed, they can only be used with the 06 lens, and preferably at its longest focal length. Any attempt to mount these tubes on a wider lens will result in a too short focusing distance, making the combo highly impractical.

When used with the 06 lens at 45mm though, they can be quite a bit of fun to use. When used wide open, the pictures are a little "dreamy", but they get sharper when stopped down to F/4 or F/5.6. These tubes absorb a lot of light so you find yourself shooting at F/2.8 1/250 and ISO 800 in bright sunshine. Here are a few shots -none of them cropped- taken handheld in available light (which means the quality is not great because it's very hard to steady the tiny camera enough to cope with the razor-thin depth of field):



This bug was about 4mm long (taken with the 21mm tube):





The tip of a petal:

Nice job on the pics Abbazz. Which extension tubes did you get? The manual focus ones? Or the ones that support auto focus? If the latter, I'm curious to hear how well the AF works. If the former, how hard is it to focus manually given the narrow DOF?

Thanks!

Thank you for the kind words. Yes, this is the autofocus version. IMHO autofocus is totally useless for macro shooting (it's easier to prefocus the lens and rack the camera in and out to get the subject in focus). But the contacts on the extension tubes are a mandatory requirement to be able to use the in-lens shutter and also because F-stops can only be adjusted on the camera, as there is no aperture ring on the Q lenses.

Regarding AF speed with the tubes, it is roughly the same as with the bare lens providing there is enough light, as the tubes do absorb a lot of light. But, as stated above, I just set the camera on MF when using these tubes as I don't see how autofocus could be useful for shooting macro pictures at 1:2 magnification and above.

Cheers!

Nice to know someone has made the extensions tubes for the Q. Why didn't they add tilt? With it and 15-45 Q could be great macro camera, and shooting running insects with flash at 1/2000 !
