Yeah, but since I rarely ever use LV the sensor movement sounds kind of drown in the sounds of the mirror flipping XD

Hehe, forgetting that can give funny results. Just the other day I was wondering why my shots with a 58mm were so blurry even though I thought I was very still. Turned out I had forgot changing back after using my 500mm so the SR was overcompensating any movement by almost factor 10x :D

The custom setting to allow manual aperture setting needs only be done once and you can leave it there, doesn't affect A lenses.

The focal length selection is for the SR to work and you get used to it, mostly it's just pressing the OK button if you haven't switched lenses.
It only needs to be done when powering on with the switch, waking up from auto-off doesn't produce the dialog.

Hope that helps you :)

What is even scarier than the treacherous Mt Vesuvius is the giant supervolcano that the whole bay area rests upon and that Vesuvius is just a small part of. It's last eruption and the following collapse once created the Gulf of Naples and just like Yellowstone there are no guarantees it won't happen again.

The old road from Varberg to Borås running alongside the railway, nowadays this part is much quieter since the newer R41 was built.

Just wanted to tell you that it's easily done, it took me less than 5 min and I have never modified a lens before. I used a piece of the rod from a cotton swab as a spacer.

The function is built into the camera, but something could be malfunctioning. There is a small lever near the back element that the camera uses to open and close the aperture, when the lens is fully mounted that lever is kept in the wide open position at all times except when you press the green button to meter or press shutter release, then the camera should release that lever and the aperture will close. Afterwards it's pulled back to wide open again. If that mechanism is not working then there is either something wrong with your camera or there's something wrong with the lever making it get stuck.
Easiest way to test if it's working is to turn the aperture ring all the way to the smallest aperture, look through the viewfinder and press and hold the green button. If it works it should get quite dark, release it and it should get back to bright again.

I don't think I'll mess with the camera body, rather mess up a $40 lens than a $500 camera body XD

If aluminium tape or glued foil doesn't work I'll probably just try sanding the surface on the lens mount :)

As an added bonus, Catch-in Focus will work too. Just enable it in Custom Settings and set the focus switch to AF.
The funny thing is that playing with CIF and wondering why it only worked with one lens, and why that lens also happened to be the only one with correct Av metering, was what led me to trying the aluminium foil trick :)



That's a solution too, but I think I prefer reversible solutions at least for the time being.

I'm not sure which contacts actually matter, but since lenses with an all-metal base short all the contacts anyway it doesn't hurt anything.
I'm thinking of getting some kind of aluminium tape to have a semi-permanent solution, fiddling with foil is more of a temporary one.

I haven't had much trouble with that. I have found metering to be pretty consistent, sometimes I have to make minor adjustments but nothing serious.
Read somewhere that Matrix mode could be the culprit and as Matrix mode is automatically disabled when mounting a manual lens on newer bodies it doesn't cause that much trouble anymore. Since I haven't experienced those issues firsthand I don't really know.

Just found this thread and wanted to add my experience.

My K-x differs two full stops between Av and M modes on two of the three M42 lenses I own. I found that my Helios (the one that meters correctly in Av) shorted the contacts on the mount while the other did not. So I tried putting some aluminium foil between lens and mount to short the contacts when I attached the other two lenses and it worked, I now get the same exposure in both Av and M modes with those lenses as well.

So FWIW shorting the contacts seems to work on the K-x at least.

Yup, seems that way. The Helios seems to be the only one of my M42 lenses with enough bare metal to get accurate metering in Av mode. Will have to fix the Sicor-XL and ZM-5SA so I won't have to fiddle with foil, would you recommend filing off some paint with sandpaper? Or maybe I'll just get a some aluminium duct tape and do a less permanent fix? XD

I still think it's silly, why would the lack of electric contact make it underexpose by almost exactly 2 EV stops in Av mode but not in M mode? The amount of light that comes in through the lens is still the same. Doesn't make any sense to me. (I don't really expect anyone outside of Pentax to know the answer to that, it's more of a rhetorical question)

What you are saying would be true for an M42 lens but since his is K mount it doesn't work the same way.

Hi there and welcome :)

It has been brought up earlier in this thread, K mount lenses actually don't stop down until you either press the button to preview/meter or press shutter release to take the shot. The rest of the time it stays fully open. Just mount it fully and try that first.
