I take your point, but there is a certain confidence gained from built in redundancy. Not quite the same I know, but mechanical shutter speed control as a backup was sold as a feature on the LX and other high end cameras of the day.

As I said earlier, it all depends on the spin and I live in hope rather than expectation

If they did that then Pentax would more or less be admitting that there is a problem with SDM (what other reason would there be to disable it in-camera) so it's very unlikely to happen.

I have to disagree, if spun correctly it could be marketed as a unique feature of Pro Pentax Glass. Much more value to me than WR. I can't remember the last time I took a memorable shot, when it was tipping down with rain.

I have advocated a menu option, which would allow SDM to be disabled since K10 days AMD something that I hoped would ne included with every model since I appreciate that it might expensive to incorporate into old model firmware, but surely not if included at camera launch?

Well hopefully it might appear on the K3!

I regularly put my DA* lenses on a AF film body to 'exercise' the screw drive mechanism. Then again I turn aperture rings and focusing barrels on all my lenses every month. I also make a point of priming and firing shutters on all my cameras

I am sire I was told that it was the right thing to do back in the 70's or maybe I have too much time on my hands.

As I stated previously, the aperture ring needs the spring/ball to hold it in place, whether that be @ F1.7 or 'A'

Without knowing more I wouldn't mind it being de clicked, but would need it to still click/ lock into the A mode.
Not sure if its the same part doing those tasks or not.

The same ball bearing is used to click on the idents on the aperture ring and the 'A' button. If you want both, you could remove the aperture ring and sand down the ridges, in effect removing the idents. Then refit a pressure spring and ball.

Alternatively use tape to hold the aperture ring in place.

If it has been declicked, I assume the small ball bearing and pressure spring, that hold the aperture ring in its selected position have been removed. Replacement ball bearings and springs can be sourced online relatively cheaply.
Disassembly guides are also online.

Consumer protection laws aside, I would have thought being in Japan offered distinct advantages. Before revisiting the retailor, I would be contacting Pentax direct and making them fully aware of the situation. I am pretty sure that they would not want an authorised agent to be acting in the way that you describe.

Time varies, according to the overall number of submissions they receive at the time. From memory somewhere between 7-21 days. The amount of voting you do yourself also seems to have an influence.
