I don't have a spare adaptor - I use both of mine. Personally I would recommend the Pentax original, but they can be very fiddly to use. They come up for sale quite often, but sometimes they are quite pricey 30 plus, I paid around 20 for mine ! I don't use mine with the little locking clip, I remove it (it is held in place by a screw or two) and then screw the adaptor to the back of the lens and bayonet it onto the body. The danger in this approach is lens can detach if you're not careful, but I hate fiddling with the adaptor in the throat of the camera body to release it

Others may have a better technique though

I use the same technique with my lenses. It's a pain if you come across a lens with a slightly more damped (stiffer) focusing ring as the lens will sometimes unscrew itself while you try and focus it.

I've got a number of genuine and third-party adaptors if you're interested. I'll start a new thread and add images later.

Are these full auto? If so I don't see how you can stop them down with (say) a K5?
Both the *istDS and the K5 are incurably addicted to old glass

They are not full auto on a DSLR - they are on an M42 film camera - so you have to do stop down metering on your K5. Fiddly, annoying, slow - but the results can be worth it

I use a K30 as a dedicated m42 camera with the adapter in permanently and carry two bodies.95% of my shots are with m42 gear.

I agree and disagree with John here

Depending on the situation, sometimes M42 lenses can be more convenient to use than say a K or M lens as the camera meters at whatever the aperture is (at least in Aperture Priority mode). There is no need to stop down as opposed to using a K or M lens where you'd have to shoot in M mode and use the green button to stop the lens down for the correct exposure. So just set the M42 lens to "Manual" on the lens barrel, set the desired aperture and leave the camera in A mode, the camera will take care of the rest. This is especially useful when shooting in bright situation or when shooting a lens near its maximum aperture (i.e. Near wide-open).

The downside to this is that because the lens is always "stopped down", when shooting anything below f/4 the viewfinder would become really dim. The remedy to this is to shoot in live view in A mode and the brightness would be boosted on the LCD screen to maintain "viewability". Shooting this way would also benefit in having a full-time DoF preview as the lens is already set and is at the desired aperture.

The only true inconvenience when shooting M42 lenses is when you want to change lens in the field or when you are in a hurry!

Anyway, it's just my 0.02 worth

The reason I asked about stopping down is that although these have aperture rings, they might also have an actuator pin on the mount that a film camera would push when you release the shutter. You can set the ring to any value you like (on a generic M42 auto lens) and the iris won't budge from wide open until that pin is pushed. Therefore green button stop down metering won't work (there's no stop down lever). If the pin operates the iris then my question remains? That is why many M42s have Manual/Auto switches, to engage or disengage the pin. I see no such switch here. For example, Helios 44M lenses have no switch and will only operate wide open unless you open the lens and do surgery on it to permanently enable the pin.

What was the f value of the 1st sample image, above, please? Looking at the DoF I would guess it is f2.4, or, wide open. (The 2nd one is flat on so won't show a DoF effect). What happens when you push the pin with the aperture set to f22 ?

An image of the rear mount plate might help, so we can see exactly what it is?

When using m42 lenses I use aperture priority. Focus wide open and click stop down to required f stop use the a/m switch set to m on the side of the lens.
Or am I misunderstanding your point.?

The first image is at f2.4, the second is at approx. f9.

There is a pin at the rear and the A/M switch on the side, the switch can be seen in this photo (centre lens):

They are great lenses that have a great 3D feel to them when used for close up work.

When I owned mine I preferred to shoot with it wide open as it's mental sharp wide open, the DOF falls off straight away and the bokeh is soooooo nice!

I would say this is the older M42 version of a lens like the Pentax limited 35mm f2.8 macro !

That's the answer I needed. There is an A/M switch. Sorry to have been an awkward so and so; the original image didn't show it.

Not "awkward" David - "inquisitive"
