Thank you all for the insights.
Film is very indulgent with light conditions, the mercy of the latitude softness the inaccuracy of the meters and you can still have good results.
But when using the P30t in a sunny day I read 1/30 for a ISO200 was like a big WT.... (and the next letter).
Regarding what Texandrews says, I have two (cheap) hanheld light meters: a Gossen Bisix II and a Zeiss Ikon Ikophot t, both reads around 1/1000 speed but the comparison is extremely unfair because they are not spot-meters. I did it just for fun.
Anyway, the info about the cloudiness in sensors (thanks Andrewd) I think is very helpful.
Some of you said that this numbers are not to be worried about, so I'm not sure if its worth to dismantle the whole stuff to check it, but it is good to have it in mind.
Again, thank you guys.

Hi Macario
It was handheld but you could think in a human tripod: same chair always in the same spot, my elbows supported in its armrests and the top of a chimney placed in the middle of the viewfinder. I am sure the scene doesn't change significantly by the position. Also I travel trough the bodies back and forth and did the measurements several times with repeated results.
Nevertheless, the "gray card test" with artificial light will be my next move.

(And now I want to eat some pudding, thanks for the subliminal message Steve xD)
The "experiment" was only to measure through a window and taking notes using the same lens for different bodies, not even same focal lenght through different glasses, taking advantage of the K-mount we put and remove the exact same lens to minimize what you pointed out.
I don't take pics with the "experiment", but seeing the history of negatives, in general, the P30t has denser negatives than the ME Super, and you can notice it with naked eye. In general, I don't have problems with overexposed negatives coming from the P30t, the correction is not so hard, but on the other hand, in some cases I do suffer the underexposition with the ME Super.

I'll take the gray card suggestion, yes yes, it was completely off my mind that resource.
I don't have a 18% card but a solid color wall would comply perfectly I presume.
I'm gonna do the same experiment with the card but so far, according to what you say, this wide results are normal (somehow).
Film is very forgiving, true fact.
Thanks.

Hi guys:
I have several Pentax film cameras and in a photo field trip with a friend, also Pentax user, we faced a problem that somehow bother us, which is the reading difference, between two cameras, measuring the light for the same scene.
Once at home we conducted a detailed experiment to quantify the difference of all our cameras, measuring with the same configuration the same landscape through a window: portion of a lake, mountains, trees, a building and some sky in an afternoon bright with some shadows (17:00 hs. or so)
ISO 400, 80mm lens (same lens always), f/11 aperture.
The "Sunny 16 rule" states for that configuration a speed of around 1/1000.
Two MZ-line cameras (MZ-5 and MZ-M), the most modern light meters we have, read 1/500. Expected due to the averaging algorithm.
A ME Super and a Ricoh KR-10 (cousing of Pentax) states 1/1000
Another ME Super goes to 1/2000
And two others, a MX and a P30t overexpose by 2ev reading a speed of 1/125
Those two were the most awkward results. In the MX I can blame the age, but with the P30t I have no explanation, cause it is pretty much the same age that MZ-ones.
Is there any answer to this?
Is this normal for you or is there any problem in some part? if so, is it easily fixable?
Ok, thanks in advance.
Bye people.

I've never used to vote in these contests but this outstanding picture made me go out my lethargy and put it a mark on it.
Brilliant.

Hello people:
First post in this forum, since I'm too lazy for a proper introduction, this comment acts kinda like that.
Pentax user since the dawns of the times (february of 1987 my first picture ever, a child with his father's SP1000, imagine that), and film shooter as long as the chemical factories decide to keep making it.
Now I own severals second hand Pentax(es) and lenses but my first camera (MY camera, purchased with my savings) is a MZ-M aquired brand new in 1997 with its mandatory SMC 35-80 f:4-5,6 manual focus. After a couple of months I completed the kit with the battery pack, great improvement. And today, exactly 20 years later, everything is still working.
The thing is, I always wondered where was the body made. The battery pack states "made in Japan", the lens doesn't say anything but some vague memories tell me that there was a "made in Japan" label in the box (the box is not with me right now), but the body is empty, no origin.
Looking for pictures of MZ-M bodies in the web I see the labels at the bottom where, below the "Asahi Opt. Co., LTD" always appears another line with "assembled in Phillipines", and in MZ-5 cameras "made in Japan" instead.
But mine has a label just with the "Asahi Opt. Co., Ltd". No Japan, no Phllipines.
Serial number is 7495320, can anyone identify the country of origin? could be a japanese MZ-M? chinese perhaps?
This is just for curiosity.
Thanks for the answers and also thanks for the countless resources that I took from the forum in the shadows.
Regards from Argentina, Luis.

I've never introduce myself, this is a good opportunity to... not do it anyway and post a message to see if this red devil wants to travel.
;-)
Bye.
