Can you control the aperture with the MZ-7/6 from the body? I thought only the Z1/Z1-P and MZ-S had that feature.

The MZ-6 can set the aperture from the body, the MZ-S can't. To set a specific aperture on an MZ-S you need a lens with an aperture ring.Can you control the aperture with the MZ-7/6 from the body? I thought only the Z1/Z1-P and MZ-S had that feature.

This seems to be a very clever device which hooks up to the camera's SR system to facilitate longer exposures for astrophotography without a very expensive tracking mount.
Should interest some of you I think.

I may be wrong but whilst using manual focus you can obtain focus confirmation but no lens will autofocus unless it is specifically designed to do so and have the af screw/ af mechanism in the lens etc
I am not aware of any m42 lens with this but stand to be corrected.
You're wrong, consider yourself corrected. To be more accurate, you are correct in saying that no M42 lens is capable of AF by itself, but it can be made to AF with the addition of this.I may be wrong but whilst using manual focus you can obtain focus confirmation but no lens will autofocus unless it is specifically designed to do so and have the af screw/ af mechanism in the lens etc

The SMC Pentax-F 1.7x AF Adapter is exactly that, a 1.7x magnifying auto focus adapter which makes any manual focus lens auto focus, with a few exceptions listed in the documentation. EG: It would not work with my 135-600mm lens when I had it.
An MF lens does have to be partially manually focussed first to get it somewhere near focus, then the AF adapter copes fine.
To turn a screw mount lens into an AF lens you attach the AF adapter to an AF capable K-mount body, mount the K-mount adapter to the AF adapter, then screw the lens on.
Simples.
Look at the first line under General Description here.

Thanks, Algi.
All available light.
The b/g in 2-4 was "as-is", if you see what I mean...the kitchen wall(!)
But 1 was meant: a backlit shot against a (kitchen wall) in shade, darker.

#1 would be improved with a darker background I think, and it shouldn't be too difficult.Thanks, Algi.

I won't add to the advice already given as it's all been said, but I've had problems with Picasa in that I do all my raw editing in Lightroom, then send the edited image as a jpg to Picasa, which promptly changes the colours somewhat.
I find it really annoying at times because it can completely ruin a perfectly good image at times.
BTW: I think the moth is a Hummingbird Hawk Moth.
