If it's a good deal, then buy it so you're not sorry. Then you can sell it if it doesn't work.
But it's a K mount, 90% sure. If it has a pin, then it's a Ricoh, still solvable.
The position of the red dot to the aperture lever seems ok.

@jmg257

Thanks for taking the time to test this.
This is a counterintuitive implementation, wish they would rethink it or at least explain it better in the manual.

If I understand correctly, for each lens we can set 2 values, a common one - the ALL; and a value that depends on the lens - the ONE.
Then we can select one of the two values for each lens, and the camera will revert to the last set value for that specific lens.

While I'm sure there's a calibration procedure that works well with this specific implementation, I wish they would give us the procedure. Now it looks like a factory calibration tool with no instruction about how to use it.

Nicely caught light. The bicycle rider adds value.



Love it. you used an ND most likely, isn't it? How did you set the exposure?


Striking blues, fear. Didn't realize Elitechrome pumps it up so much.



Nesster, you are the head tinkerer here. The feel must be absolutely special with those old photographic machines



A nice vintage feel.
As I understand, photography is what you do for a living. Am I right?



How do you like the Fuji? In my area it became extinct for a while. Only Kodak Gold 200, and used to hate it. For a while I avoided buying it (this is how I ended up buying the Ultramax 400 for an astronomical price), but I think they upgraded the formula or it was a really badly stored stock, because I started to like it recently. Either that, or my standards changed.
Now I am able to find again the Fuji C200. I bought the last 3 rolls from my go-to salesman, and asked for more.

It's about imaging in the end. People like things that are easy to use. Many pro's choose huge DSLR's for sheer sensor performance and fps and use it mainly as expensive P&S's.
The Bang Bang Club is a great resource of information about the golden age of photography.


BTW, I like your sig.

Hehe, VIVIAN MAIER did the same thing.
And ease of use is the main reason I love my ME Super. This kind of design has a special elegance in it.


No-no, I was referring to the current tendencies. My gf is a strong representative of this modern age, she likes to chimp to the rear LCD. However, I recently developed a B&W that was sitting in the ref. for a couple of months, and she was amazed seeing the results; now she became more understanding about my ways.



Another point, valid in my case at least: lots of great lenses come attached to old cameras, still functional. I see it on this forum all the time.
Ease of use combined with the huge VF. Hard to beat, really hard.

I feel the same. Digital looses the quality battle due to affordability. Everybody can take pictures nobody likes.
My friend asked me once: "how many times are you going to see your photos - maybe once or twice?"
Well, not me. I only shoot a roll a week, maybe.



Oh, I had this reaction so often. Still, people look to my metal cameras with great respect.
Could be that these old cameras have the quality touch forged in?



I tend to apply the same type of use. It is impractical to use film with off camera lighting, for example. I would not have the guts to cover an event strictly on film. Chimping on the LCD for light balance and having the instant result in front of your eyes is both reassuring and helping me in adjusting the parameters.
I use to say: "Analog for myself, digital for others".





This is good news indeed. I really think the chemical process is a much more mature product than digital imaging is. I mean, it's almost 200 years v 30. Would be a huge shame to flush down all this technology that gave us so much.

I really really really hope it's true what I heard from one pro shop I e to process some 35mm slide film.
They only do chemical processing and printing. And their business is getting better and better for the last couple of years. According to the shop owner lots of pros got back to working on film only for fashion and wedding...

There's also this discussion. It's interesting how big companies like Kodak and Fuji still see profit in film industry. Those are hardcore businessman that cannot afford to be romantic in any way about the future of their companies. So, there's still a market there for millions.
That would mean film days are not over, right?

I'm glad this goes this way, but what could be the actual reason seen from people's side?
-Cost v quality is arguable because most people don't see better quality. Actually, digital is more flexible with variable ISO.
-Size is not an argument either.
-Could be people sick of filling up the hard drives with lame phone pics?
-Could be the need to be different?
-...?
I know I'll never give up up digital, I am going through some kind of phases. I enjoy my K-5 low ISO, shutter noise... , but I simply love the ME Super VF size, and operation.

Here is my contribution.
The following are taken in Gijon, Spain in the beginning of this year. Rainy weather has some good and some bad sides to it.





Strange color shift in this one, probably due to the under exposure. I like it tho.






Film used was Kodak GC 400 Ultramax scanned with Plustek 7600i. Pentax ME Super with K28/2 (zeiss formula with floating element).

Wonder how fast is the CDAF on the K-01...
Come to think of it, on mirrorless cameras the accuracy of the AF should be better since the image sensor itself is the AF sensor.

I suppose the limitation on current CDAF system is not knowing the amount of focus correction needed for perfect focus. Since it is "contrast detection", AF works in a feedback loop, that making it slow. Just give it a couple of years.
This is most likely the future of professional cameras. Lightning speed CDAF.

That is something new!

In my understanding ALL is the "camera offset", ONE is the individual lens adjust. They should be additive, in the menu both values show in the same time. Otherwise one or the other should grey out, isn't it?

Sorry, I think you may have misunderstood :lol:
I mean :
-the factory correction value is there to bring the lens as close to perfection as possible. This is written in the lens and taken into account by the camera IF the microadjustment is OFF.
-If ON, then the camera will ignore the factory correction value, and use the user value.

In this way a regular user does not have to fiddle with the settings (leaving the feature OFF), while another one with issues can turn it ON, and adjust.

Remember this: Default is OFF.

Sounds reasonable, no?

Of course the adjustment values MUST be transmisible! If lenses are thrown on the market without calibration, and cameras are sold without the calibration done, we would have a good match in a million!
I have read that article previously, but the explanation doesn't satisfy me enough.

-It is much more cheaper to make equpiment with a wider tollerance and then write on it's chip ... +5, instead of aiming for perfection.
Camera will take the +5, add it to it's calibration, say -2, and adjust the focus to +3. (this happens when the microadj function is OFF)
-I'm not arguing that, in time, the equipment won't fall off it's initial calibration value. Then, the Microdajustment becomes usefull.
-Don't forget that the microadj. function comes from the factory tuned OFF.
-I don't pretend that ALL my problems with lenses are solved since turning the microadj. to OFF. Just the accuracy of the autofocus.
-I'm not going to say ALL new cameras owners should turn the function OFF. For me it worked, since most of my equipment is new, with little use.

Finally, how to explain that not only me but some other forum members got better results with their own lenses by turning the microadjustment OFF?

I had the same idea, but additive would make OFF = Zero adjustment.
But I found that microadjustment ON @ zero is very different from microadjustment OFF.

If lens microadjutstment value are not absolute but relative to a body, than the microadjustment values are not transmisibile.
Think is logic to work with absolute values (on both camera and lens) and not relative values.
In this way a manufacturer can calibrate a lens (via the lens chip) in the factory and that lens will be useable to multiple bodies.

I used the Jeffrey Friedl's Blog chart.
And no, the AF micro-adjust is not gimmicky. I'm sure in some cases is a great tool.

My point is: Normally we don't need it. Normally we should keep it OFF.
As another poster said a while ago, we are not paid to do calibration work for Pentax.

When I attempted the calibration, I printed the 5% version to be sure the camera wasn't focusing near the target.
I was getting constant backfocus with the FA77. While adjusting, I could see the clear area moving towards the target.
When I disabled the micro adjust, I got constantly perfect focused images with all my lenses.

Come to think about it, it is working in a logical way for the people who do calibration as a day job. The implementation looks poor to me, because it's not user friendly or intuitive.

This is great news. Let me rant about it:

Probably when the micro-adjust is off, the camera defaults to factory adjustments (camera & lens). This is logical since only a small number of users will perform micro-adjustments. Custom is OFF
When the setting is on, micro-adjustments default to 0 (regardless of the factory calibration). Then the user has to find the values himself.

SO: Micro-adjustments OFF could mean: camera +2, lens +9. We always presumed OFF = 0.

Else said, if my rant is OFF not necessarily = 0.

If you have doubts weather the remote battery has charge, switch the camera to Live View, bring the remote LED in front of the camera and press the button.
The sensor is IR sensitive, so you will be able to see the LED blinking.

Cool, ha?

But... I don't get it.
If you want to use your camera for video, and you can get good results with an external mic, why don't you invest in one?
It's like complaining you don't get pixel perfect pictures with the kit lens.
Have it crossed your mind that all that work by CRIS will affect the camera irreversibly? And for what?

For me a lockup happens all the time when I'm using PK Tether and do some things in the wrong order.
For Ex, press shutter command on PKT while in LV.

So, no worries. Glitches happen, we have to find our own ways to work around it.
