Hence why I am so puzzled right now. Would dust particle in the lens cause such issue at smaller aperture only? Or, is it down to sensor (if so, is it faulty?)
Please advise
Well it looks like muck on the sensor to me, and yes, it does tend to be a lot more obvious at small apertures than large ones.

I would lay odds that it will be visible with other lenses now. Take a picture at small aperture against a bright featureless background, and see if it's there.

It wouldn't be in the least surprising if the muck got in during a recent lens change and you've simply not noticed it till now.

Do you mean this:

??

If so, and if it's in the same place in every image, it's almost certainly muck on the sensor that you haven't seen before.

It would be very helpful if, rather than describing where you're talking about in words that are doubtless clear to you, you make it completely clear where you're talking about.

What sort of things was it missing?

Bet that shocked you Chris!
Nah, I'd have just assumed that the AF mechanism had been completely removed, rather than just working on Wednesdays

Having a couple of goldcrests in the tree outside the window, my hat is doffed to anyone with the patience to capture them at all, let alone with such delightful compositions as these.

But am I the only one here that thinks they're a bit oversharpened?

You would probably be better using the £100 to invest in a more modern, digital friendly lens.
At or around that price point, avoid the Tamron 70-300, since that would be very much a case of out of the frying pan into the fire.

I think I'm the guilty one re the black cloth, but as regards the tube idea I think you'll find there's already at least one on the market.
I imagine the viewfinder was invented, among other reasons, to solve this very problem.

The K-01 brings a whole new meaning to the term 'retro'. I mean, I wish them well with it and all that, but seriously

IIRC, I think someone joked about using a K-01 with a black cloth over it and your head, so as to be able to see the LCD in bright sunshine.

What we need is a clip-on rectangular tube, about 6 inches long and the right size to surround the LCD, with an optional reading-glasses lens of suitable strength, a little way in from the eye end.

Presto, a viewfinder.

Surprised Don hasn't already made one.
