How to use old Pentax lenses on Pentax DSLRs

This should probably be a sticky...


On piece of info he did leave out, on the K-30 you have to turn AutoISO off in M mode.

We actually posted a similar video a couple of weeks ago on the homepage. Have you seen it?

Yes. The K-x doesn't even have to use the Geen Button. You can use the AV+- button and set the Geen Button to a different task, like Optical Preview.

The K-x Geen Button is on top of the camera rather than on the back.

BTW, welcome to the forums.

Yes. Every Pentax DSLR, it is slightly different for some.

Here is the PentaxForums video.

I just checked, my K30 will use auto ISO and I always keep it in M mode. I also always use specific ISO, never auto...but it is available. I'm using a M42 lens right now, but it's also available with my A series 50mm and M series lenses if I remember correctly. I just don't use it...

Also switched ISO to auto to test it, panned it around and ISO switched around from 100 to 800 pointing the lens at different places in the yard. Didn't bother taking a picture, just panning it around told me it is working in auto ISO while the camera is in M mode.

AutoISO in M mode is the same thing as TAv mode. It was included in the firmware because the K-01 doesn't have TAv mode (one dial). No other Pentax cameras can have AutoISO mode turned on in M mode. It automatically turns off. This is a bug in the K-30 because the K-30 has 2 mode dials and TAv mode, you should not be able to enable AutoISO in M mode on cameras with TAv.

OK ...Interesting...it makes sense that with Tav mode auto ISO would be disabled in M mode, no need for it if you have a separate setting for that but it does come in handy if you want it. Never thought of it from that perspective. Doesn't matter much to me, I keep it on set ISO anyway...

A bit off topic, but I used Av mode for the first time yesterday. I normally only shoot M, but windy with clouds rolling by pretty quick, lighting changing every few seconds, I actually put the K 30 on something other than M...I think that's a first...it seemed to work pretty well...

I would hazard a guess that most folks who use modes other than M on a regular basis use Av mode most frequently. It's simply the most important setting to retain constant control of IMO.

That's probably true. Av is the only other mode I've used, with both K-x and K30. I tried out other modes when using the "kit" lens, just to see what worked well, and usually stayed with Av until I got home and got my manual lenses, since then it's almost always M mode. On the occasional day with fast moving clouds, I might start using Av a bit more though...I can usually handle changing light conditions pretty well, but when it changes every few seconds...gotta do something...
