Thanks a lot!
Finally I found the serial number - it is covered with the rubber ring of the metre pentaprism. :)

Hello,
Perhaps it's a stupid question but where is a serial number located on the body of Pentax 67 MLU? Can't find it.

So, do you mean that for Pentax 67 lens the natural in rest position of blades is "AUTO" mode?

And one more thing about the lens - I checked my DA lens (e.g. DA* 60-250/f4) and found out that whenever the lens is unmounted from the camera then the blades automatically jump to a closed set-up. I presume the latter is the natural in rest set-up of the blades in DA lens. So, the question is what is the natural in rest set-up of the blades in Pentax 67 lens? Shall they need to be kept open or closed down?

Well, now it's clear about the preset lens, thank you. Although I'm not sure of whether Pentax 67 lens can be called preset lens because Pentax 67 lens keep aperture fully open and only at the moment of shooting the blades close down according to the preset aperture number (of course there is SMC 120 mm soft lens, which doesn't have those jumping blades).
So, doesn't it mean that Pentax 67 lens with jumping blades have the blade springs that require the set-up as recommended in entry 2 of the initial post, does it?

Hi Patrick,
Thanks a lot for the comment. Just a quick question about preset lenses - could you please provide more details about them? And any examples of them from the Pentax lens range?
Thank you.

Hi,
Here are the common sense tips of how to store lens (https://www.sharkandpalm.com/photography-tips/how-to-store-camera-and-lenses...e-value-high):
1. Store them front-element-side-down.
This will minimize the presence of oil in your aperture blades (which can really gum up the works when you try to change your aperture in the future). This has become less of a necessity with modern autofocus lenses that use less oil in their manufacturing, but it’s better to be safe than sorry.
2. Close aperture rings to the smallest f-stop to reduce tension on the springs.
The springs in your lenses, like any other springs, fatigue over time. To keep your lenses like-new, set them to their smallest aperture (in other words, the highest number on your lens) when you store them. If your lens doesn’t support manual aperture adjustments, just close up the aperture using your camera body before you turn it off.
With regards to entry 2 here is a question:
If an aperture for example needs to be set to 22 (as the smallest one) then is it just enough to turn the aperture ring to 22? That’s it? In such a case the blades don't close down physically to the smallest aperture, they stay hidden.
Or do I need to turn the aperture ring to 22 and then to switch the depth view lever from “auto” to “man” to make the blades close down to the smallest opening?
Your answers are more than welcome.
Gennady

Hello,
Once, on my way home, I stopped at McDonalds to have some snack. And there I saw a girl who was waiting for her mother to bring some food to her. The girl's expression of being bored was so vivid that I could not help but take a picture of her. And here it is - a portrait of boredom. :)

By the way, what is the Pentax policy with the stained sensors? Should they change the flawed sensor of the camera or must they replace the camera?
