That is why they introduced stop down metering in the cameras
All the Pentax cameras will perform stop down metering if a lens is attached that does not have an automatic diaphragm, but all cameras from the Spotmatic F onwards (not SP1000) and all bayonet mount ones meter at full aperture with the appropraite lenses.That is why they introduced stop down metering in the cameras
Stop down metering is not something that has been introduced, it has always been available. Current DSLRs meter at full aperture with lenses that have electronic contacts.

The Pentax clip on hood is much more convenient. If you can't buy them new then they crop up from time to time at camera fairs and on eBay.

I found that as well when I tried one out.

Any of the cameras that have P or Tv modes can operate these lenses. The camera sets the aperture just as it would with any lens with the aperture ring set on "A".

Is the f8/f12 just a consequence of zooming? That is, there isn't any way you can change the aperture yourself, it just changes as you zoom?

I think there is one, but I understand that regardless of that even a standard mirror lens of fixed aperture will need the custom function to be activated.
I presume this is because there is no contact electronically with the camera so it doesn't know a lens is attached.

You can use M or Av modes and in fact if you set any other auto mode such as Tv you will get Av anyway.
Activate the custom function Using Aperture Ring by setting it to Permitted, as already mentioned.

Is this a case for buying now? Could be, looks like we might not be able to afford later.
