my minimalist (and genuinely pocketable) kit comprises an ME Super with a 50/1.4 attached

Came across this blog site today - this photographer's list of Pentax kit is enough to make one weep. Not that I'm the envious type mind.
Not sure the pictures he's published at Flickr are all that amazing, though. I think if I was going to boast of a kit list like that, I'd want some amazing photos to justify it...
There's hope for the rest of us yet, I think

If you are taking flowers, small insects that are stationary, macro subjects, etc., then the trpod is pretty much essential. You need DOF and that means slower shutter speeds.
I took these in my garden recently:

The bees were flitting around a lot, they were spending literally only a couple of seconds in each flower. I suppose with a tripod pointing at one flower I might have got one eventually, but the breeze was blowing them about quite a bit, so it would have been hit and miss even if a bee had arrived in the one I was pointing at. It was easier to follow the bees hand-held. I used the built-in flash to supplement the rather harsh daylight, and got a couple of decent captures out of the dozen or so I took.
The second one isn't bad, I think (comments gratefully received), but the first one really emphasises John's point about depth of field - the bee isn't sharp, although the buds are, and that spoils a shot that I'd otherwise be quite pleased with. The second one is better, I think, but I'd prefer it sharper still really.

I'd try bringing it from black to medium grey right near the base and back to black. Adding a faux shadow near the base and warping it where the grey turns to black.
Anyway, I've replaced the images; this time I was a bit more careful to not cut out stuff that shouldn't be.

especially as it looks like other bits were cut out...
I'll see if I can do a better version later on tonight.
I'll pull it for now, thanks.

Look at the bit that I highlighted and the burglar alarm box to the left. The fringing is still easy to see without pixel peeping.
I had exactly this experience with a Sigma 400mm lens - I noticed the purple fringing at full frame (it was worse than this), and only then cropped to have a closer look.
I'd metered for the foreground, but there was a high contrast, light background just as in your example.
I never noticed PF before I went digital, and I don't think this is entirely accounted for by the fact that I crop more, and look more closely, at my digital photos than I ever did with film.
As Matt says, and as some of the various references suggest, it isn't just down to the lens.
There's an interesting article at

and another one at

They don't answer all the questions, and you start to lose the will to live quite quickly once you start to try and work it all out. There's no simple answer, I suspect.

First, 300mm is a long lens on digital (equivalent to 450mm on film). You might find that 200mm is enough, unless you are photographing small forms of wild-life.
The thing about having SR, digital and effectively a more telephoto angle of view (I know the focal lengths don't actually change) all in one package is that they make photographing distant objects a lot more accessible than before, so the longer lengths become more appealing.
I'd never in a million years have contemplated

with film, for instance.
So I think that unless you're already a landscape specialist, the longer focal lengths might become appealing quite quickly.
If 2nd hand is acceptable, the 75-300 FAJ comes up on eBay quite often.
Second, although there are some exceptions, the great majority of people who get into digital never or hardly ever buy another film. Very few people use both film and digital side by side.
