I have the Kipon and it works for those M42 lenses without an A/M switch.

^^^this. I've connected it through an HDMI to the TV. You could record it there. For a field setup, you would need an external recorder.

I still shoot with a K-5. It's a really good camera. You might want to go for the IIs. You'll only need to buy new batteries for it because most of them aren't performing as they used to when new.

It certainly seems the soligor on the last pic was focused on the red chair, too.
Did you use live view magnified to that specific crop to focus?

Wow, that camouflage!
Shame it wasn't perfectly in focus either.

^^^What he wrote.
Those orange/yellow markers seem to be for actual aperture after light loss, rather than working aperture. When the lens fully extends, it seems to lose two stops of light. This makes calculating your exposure easier.

Brass/bronze is mainly used for its auto lubricating properties (e.g. phosphor bronze, a type of copper and tin alloy), and yes, in corrosive environments, too. It all depends on the specific alloy. P bronze doesn't seize up like, for example, aluminium, which tends to because its protective corrosion layer is harder than the base metal. It's rather the opposite because phosphor tends to form low friction molecules. It's used in your engine oil's additives to keep it running smoothly in place of the earlier, toxic, lead.
Avoiding cracking is another matter that depends on the material toughness, elasticity (elastic deformation, rather than the catastrophic plastic one) and cyclic stress limit of the alloy. You can't have it all in one, so you have to make compromises and choose the right one depending on the expected working conditions of the piece, plus a little leeway. That leeway depends greatly on costs and safety. For a non human endangering piece you would try to make it as low as possible to save on material and thus costs, but keep it in a statistically reasonable failure rate for the products price point.

Beautiful. Not perfect, but I know how hard it is to get the focus just right.

+1 to this one. I did the same with a 1.4x televonverter. It has Auto aperture, contacts and screw drive. Works with my DAF100 (and like others noted, with long zooms and teles) like a charm.

Not depressing. Just shows that there is way more to photography than the gear being used.
Some of them stand out, but they would be less if used at the same focusing distance. The slower macro wouldn't show as big of bokeh balls as it does, for example, which also shows that Minimum focusing distance matters a lot, too, besides widest aperture.
My thoughts, too. I own the A version, but a meeting is quite frankly, improbable.

All your work with this combination are superb. Have you tried it for milky way shots?
I wish there was a WR version of this lens. Like the Irix lenses.

The 105, which I have is nice. To tell you the truth, you have the focal length already covered. Focus on the photography. Only get it if you're exclusively focusing on close up portraits wide open (or close to) because that is where it shines. Get ready to add the #1 extension tube because it doesn't focus closer than a meter twenty, or so.
If you shoot anything else, it's way more interesting to get the 135 macro.
