These are the only two lenses, which I would have been interested in
In the meantime, I have five articles on my blog. This search should find them.
The lens takes beautiful photos!

You've explained your methodology, but not what the purpose of all this is?
1. We are having fun with our tools.
2. We prefer to have some idea which tools are better than others. Rather than just flailing about in a pool of subjectivity.
3. We need to sell lenses and would like to know which to keep.
4. We might learn something from the responses we get back from other photographers.
5. We like challenging our own expectations. Don't you like challenging yours, John?

I'm sure any of those lenses would be eminently suitable for photographing twigs
Agreed! Not best subject to test on, and also for MF lenses, out of focus causes most "not sharp"...

Most of these images are very soft, hardly anything in focus. Looking at the two stubs the A lens is crisper than the K lens and the Cosina somewhere in between. I think you'd have to live with these for a while because focusing is ultra critical and also getting the right image to use such as wide aperture effectively is a bit tricky.
Robbie did the Pentax APS-C shots using live view at x10 on a K-5. I did the Olympus MFT shots on an E-PL2, also using the LCD at x10.
The shot was inside with no wind or disturbance. Light was completely diffuse and consistent, since we had an Irish overcast day. I have blinds on either side of the room to adjust for glare control. Once set I didn't touch these. There may be slight (1/3EV) highlight burns in the extreme edges of the frame, but otherwise no overexposure.
Underexposure is another matter since Pentax exposure consistency is, quite frankly, crap. Everyone who has used a K 50/1.2 knows this.
We used my Feisol tripod to ensure consistency through apertures on a given lens. There was slight frame movement as lenses were changed. There is no practical way to avoid that and neither does it matter much, if every shot is manually focused.
Our focal point was the stamen of the flower, the top left anther to be precise. DOF was so thin that sometimes the whole anther was not in focus at the same time!
I can't speak to the ultimate accuracy of our focus ability. We did not take multiple shots so we could select "the best" since no-one is paying us to do this and we also wanted to hang out and talk crap.

Has the Leica a fitted LEITAX mount?
Unfortunately -- slaps self about head -- I forgot it in a drawer so we didn't test with it!
We did use six other lenses on two different camera systems. Considering we're not fanatical about this sort of thing (ha ha!) that seemed plenty.

Be nice to see a Voigtlander APO-Lanthar 125mm f/2.5 SL in the mix

Could have saved yourself some typing RSI by just saying "I don't like F/1.2"

Yes - the reason the K50 shot works is her pose and the good background, as well as the lens rendering - which is lovely. Not the f1.2 setting. In fact I suspect it was shot at more like f1.8 to f2?
In terms of the 'pop', I mean when the background is pushed back by a selective narrow dof on the subject. I would agree that if you go for this look, the effect undone if there's a lot of glow / coma and lens aberrations.
The FA43 shot of the cat is far too contrasty and the whites are burnt out.
It's good to get feedback on what people like. My purpose was only to show decent stuff from both lenses. And of course to ensure the continued fame of Schweppes on the web.

I've started to upload some of my test images, so they will be here tomorrow.
