aperture controlling bodies?

Quick question for 35mm SLR gurus.
Which bodies (other than MZ-S and *ist and preferably AF) can control aperture from body (Av mode) for lenses without aperture ring?

Thanks for any and all replies..

The Pentax K-m has the aperture control via the camera body control wheel on the back of the camera. It took a bit to get used to using it but I like the way it works now. I think all the newer Pentax digital camera bodies work the same way.

I think he is probably wondering about film bodies (posted on film camera section).

The short answer is that any body supporting programmed or shutter priority (Tv) auto-exposure can be used with lenses lacking an aperture ring in those modes. For the early models, that means indirect control with the body governing the aperture. Direct control of aperture from the body is limited to models having a control wheel for that feature. See Bojidar Dimitrov's Pentax K-Mount Page for a full listing including features:

Pentax Camera Bodies
The series you are interested in are: A, P, and all of the AF bodies.

all bodies since the SuperA (or SuperProgram), which is the first "A" Body that can handle "A" lense.

But some body like MZ-50 have this strange rule to not shoot if there isn't any AF lense.

Indirectly, you can in Tv mode.

While you can not set the aperture from the body, the body does control the aperture when the ring is set to the A position. But I do think Axl is looking for cameras with an e-dial that can set the aperture from the body.

i guess it's like on my SuperA : you choose a speed, the body gives you an aperture, so you change speed, you get another aperture. It's not A mod, but you can choose aperture indirectly.

The ZX-L does this, though not as easily as it might.

I would guess from Z-1 or PZ-1 onwards since FA series lenses were introduced at the same time. I don't know when FAJ lenses were first introduced but they don't have aperture rings like the current DA lenses, so in-body aperture control must have been introduced concurrently with the FAJ series of lenses.

Thanks,

As mentioned above, it was long before FA or FAJ lenses were introduced. It was when A lenses came about, hence the "A" setting on the aperture ring allowing the camera body to control the aperture.

With the MZ-S you actually cannot control it directly, you can only use Tv mode, and then control the aaperture through the Tv

thanks all for the replies. I am indeed looking for film camera that can use Av mode. I have DA*55 which supposedly covers 135 frame but lacks aperture ring. So I'd love to be able to use normal Av mode with e-dial. Unfortunately Z/PZ bodies were not on top of my list but it seems they might be the best option... and if they can handle AF500FTZ that would be added bonus...
