I've been trying to find interesting ways of using the strong field curvature to actually keep more of the foreground in focus while still having a fairly shallow DOF... no spectacular results yet, but this kind of illustrates the concept, I think...

Good thought. got to give this approach a try. One idea comes to mind: I imagine a jetty scene at sunrise / sunset might be quite interesting.

For those who are interested:
I went into our machine shop and took some thread gauges to the lens hood on this lens, and it appears that the thread is a M31x.5, which clearly isn't a very standard size. For some reason I was expecting an imperial thread, but the thread major was right at 31mm and the under a microscope, the .5mm thread gauge looked about perfect. I was hoping that I could just buy a die and make a custom filter holder/hood, but it looks like you have to single point cut the threads. I guess for now I'll have to live the bent lens hood from a drop in the garage. I might throw the idea out to a friend who has a hobby level machine shop in his garage, but I'm not sure how interested he would be in cutting those threads. Anyway, I'll keep you all posted if I get around to making something (probably less likely knowing that a O60 macro is coming my way for Christmas).

I was thinking of it as 50 TPI and some arbitrary diameter determined by other aspects of the lens design (the O.D. is a clean 1 5/16"). The sample size is pretty small for accurate guaging, but you could be right... I mean, once you start calling your 2 1/2" lens "63mm", it's a slippery slope... :D

That's funny - I started neglecting my O60 macro when I got this lens... goes around, comes around! As similar as they are in FL/aperture, they're otherwise about as different as two lenses could be; I guess I think of them more as a yin/yang pairing than "redundancy".

It's possible that it's not metric, but my US customary thread gauges only go to 46TPI. If it is a US thread, then my bet is on 1 7/32" - 50. The more I think about it, the more likely this seems. I put the calipers on it, and it does measure 1.218-1.219, as it's a little out of round. With only three or so threads engaged, you could probably use either, they're pretty darn close (1.2188 vs 1.22 and 50 vs 50.8 TPI)

I try so hard not to have these kinds of evil thoughts... at least I didn't have to be the one to say it. :whistling:

Just out of sheer perversity and to bring it all back around to an image thread, I stuck a loupe guage on the end of the lens in question and took a look at the hood threads...

Not really accurate enough to say either way, but does suggest 50 TPI would probably "work".

Variations: near, far, in dimness and in light, uncropped and tightly cropped. Being a cloudy evening, some of the pics were adjusted for contrast, exposure and saturation.

Bright day: Stopped down to gain DOF, cropped away as much of the vignette as possible.

Waiting for the snow to stop before I have to shovel again...taken through a bedroom window and post-processed with NIK Silver Efex.

My AK63 has not come off my E-M5. I keep being amazed at the resolution power of this 70 yr old lens. My rubber band hack of Gnarly's idea of removing the focus range limit stop makes it very easy to go from far to close subjects.

More! Have to admit I'm obsessed!

Just for fun, I stuck a blob of putty onto the middle of an old UV filter and put it in front of this lens to take some donut bokeh holiday light pictures...

I'd say it's well suited to that kind of monkey business.

Finally got a chance to really test the adapter. I think I am not getting infinity focus, but I love the closer up results. Trying to use the field curvature in interesting ways

Is the S>C adapter threaded as far as it can go in the C>M4/3 adapter? The neat thing about this lens is that you can probably work around it by just pulling the stop pin up, and focusing back past the infinity stop. As others have noted, it can be convenient to just shim it up semi-permanently... mine only needs a mm or so. I cut a slot in a tiny plastic washer and snapped it in place:
