Transition from Pentax K100D Super to Pentax KP

luebeck · 10-08-2022, 08:22 AM

Hi,
after 15 happy years with the K100D Super I bought a used KP now and this seems to be a very good camera.
But as a happy owner of a collection of legacy K lenses I'm still struggling to get the exact exposure.

My lenses are K 1:2.8/24, K1:3.5/35, M 1:1,7/ 50, K 1:1.8/55, K 1:2.8/105, M 1:4.0/50 Macro, A Macro 1:4/200 ED.

The K100D Super has a basic live view function, but with a histogram, perfect for manual adjustment of time and aperture.
The KP has a very advanced live view, but I miss the histogram, possibly hidden anywhere in the menu.
Any idea how I can get the histogram in M-mode before shooting?
Another issue is the connection of the camera with a PC or my Ipad. No problem with the K100D, but with the KP this does not work.
Set to "MSC" USB-mode, I tried 4 different USB B cables and two different notebooks: the camera looks in some way but is not detected by PC or iPad. I could switch to SD-cards, strongly recommended anywhere here, but I'd like to know, if this is a possible hardware fault or some kind of wrong configuration.

Thank you!
Guenter

Go to screen 5 of the Camera Menu, click Live View, check the Histogram box.

I suggest using the wireless connectivity as another option.

Unluckily histogram is not clickable here

Yes, that‘s possible, but requires about 20s per ***jpeg.

You must have something set which interferes I just checked in Auto, M and P modes and it is always available. Check your set up. It works fine on my KPso it should on yours.

In screen 1 of the camera menu go to AF with live view and disable focus peaking. The reason that both histogram and highlight alert are greyed out is due to focus peaking being on. In the KP these two setting do not work together. In earlier camera's you could have focus peaking and histogram turned to on. After disabling focus peaking return to screen 5 and set the histogram view.

Thanks to all of you!
Meanwhile I found a preview solution when customizing the buttons. Now the preview is very similar to that of my K100DS and I can work with that. My procedure is:
First press the fabulous green button to set the exposure suitable for present aperture. Then check the histogram with Fx2.
Great!

I guess you will not see the camera, but with the right cable and camera set to MSC you must see a new drive in the drive-tree, usually the last one. Procedure: start up PC, connect the SWITCHED OFF camera with the cable and only then switch on the camera, on the camera LCD you must now see a symbol representing the connection. Start file explorer and in the drive tree you should see the new drive which is your camera.

By the way: When using all those old K and M lenses make your camera fully manual and set the exposure and shutter values as you used to do with your MX. With A lens it is another story.

If the KP has MTP mode for USB settings you might try it on your PC provided its Win10 or 11. I'm not sure if the iPad supports MTP. If that does't work the USB port on the KP might be faulty. Test the cables on some other USB device to make sure they work.

Yes, that I'll do and report then.

Just collected some experience with AutoFocus Fine Adjustment. Works with legacy lenses only with "Apply All". Probably because legacy K-Lenses do not have some kind of personality like modern e.g. DA-Lenses. So I made Fine Adjustment "Apply All" for my Pentax SMCs A Macro 1:4/200 ED. This adjustment of +5 luckily also fits my K 1:2.8/105 and probably the other less critical lenses also.
And an observation on "Preview" with histogram, mentioned above. That does not work with "M.UP" mirror up, multi exposure and "INT" intervall shooting.

I have tried everything, including suggestions here and have never been able to get my PC to recognise my KP.

Hi Terry, welcome to the club. Meanwhile I found the hidden SD card reader at the lower end of my PC and I‘ll adapt to swapping the SDs.

If you find some manual lenses need different adjustments, putting labels on dedicated lens caps that state the amount needed will allow you to go to that menu and change it quickly.

A very good idea! Thank's a lot!

You’re welcome. And it’s not original to me. I stole it from someone else. I don’t even use the idea as I rarely use manual lenses except in liveview, where the af adjustments are not relevant.
