Those are A-bellows, right? I happen to have tried/used the exact same combo last autumn, to test how a little more working distance than my DFA100WR offers at 1:1 would feel. Funny thing, I even used my trusted K-5, not the K-1 as usual.

I don't find it
extremely difficult to use anymore thanks to life-view (kept the aperture stopped down), but sure it soon felt a little heavy hand-held. Admittedly the subject below was easy and sitting at a good height.
Here's light-handed edit of one of the results - full picture, rotated 180deg. I was surprised that the A200 F/4 renders reasonably well at macro-distances. Given that it's not overly well corrected, I expected a lot more green and purple out of focus edges. In addition, even at full magnification, there is a good amount of detail and it doesn't suffer from a hot spot, as it does on my 3rd party extension rings. Still I'll keep looking for a longer macro lens and maybe use a TC meanwhile.
