BTW, it functions in Auto and Manual modes as well as Program, and I can live without P-TTL (I have managed to do it since the early '60s, after all).
I have nothing against 3rd-party manufactuer when it comes to flashes, and I am open to any suggestions (provided the have a low trigger voltage, of course)

Its purpose is to enable the assessment of spectacle and contact lenses, and is good for indicating astigmatism correction and power. Long since replaced by the OLH-2, and then by much more powerful test equipment, this is of no real use today (even though it works just like new). It is offered as something of interest to the collector of all things Pentax. The kit includes the original holders for 8mm and 10mm contact lenses, and an adjustable platform for spectacles. The case forms a stand when in use. The vacant slot inside the case is for 2xAA batteries.

For some time I have wondered about the insistence on Pentax Cameras, but not on the lenses. OK, so with a digital, the body does the initial processing; but with film, the body merely hold the film in place.
So if I put an E.German 58mm f2.8 lens and a K/M42 adapter on my K20, then an image would be taken with a "Pentax Camera". If I put a Pentax M42 lens on an old Praktika body, any images will not be taken with a "Pentax Camera", even though the image basically results from a Pentax lens.
Reverting back, the idea of re-reproducing an image makes me want to try it (its one of the few things that my ever-decreasing mobility will let me do) but I will try with a Pentax generated image - just in case I like the result. Now, where did I put those A3 competition prints?

Epoxy resin - you cannot get a fine film
Mix the resin on a piece of sheet aluminium (even thin steel at a pinch) and warm it on a cooker hotplate - it gets very thin/runny and you can apply it with a small brush.
Throw the sheet and brush away afterward, of course.
The trick is to use enough to get a consistent mix - but this can be cheaper than a poor repair.

Working the 'net hard, I conclude that an AF280T might do me just as well, or a low-end Yongnuo.
Comments, or offers, will be appreciated.
