Damn.
You get some luverly pics and WHAM, an invasion of lens bacteria; notably at full focal.

I understand this can be countered PP, however I don't know/assune it too time consuming.

Apart from being fastidious with lens brushing, Is there summit pre-shutter that can help reduce thon swarm?

It's probably on your sensor, not your lens.

Is it more noticeable at smaller f stops?
 
Its probably dust bunnies on your sensor, take a pic of a plain peice of paper at f22 and see what happens.
 
Yes, I don't think bacteria comes and goes or invades! A useful tip when changing lenses is to keep the camera body facing downwards, to help prevent this kind of thing. You might need to get special swabs if it's more than just dust specks...

This. Dust that you can see in pictures is almost never on the lens. Always on the sensor.

Have a seat handy because you might need to sit down sharpish. If you never shoot at f/22 - and most of us never do - you might be appalled at what you discover.

Depends what software you use, in Lightroom it is a one click operation to remove dust bunnies, depending on where in the frame it is of course
 
I had these the other week so had to do a 30 second exposure whilst I got in there with a cotton wool bud. Dust free shots now.

Woahhhhh, i wouldn't recommend doing that, you could have damaged the shutter if it came down whilst cleaning it

Most cameras (if not all) should have a sensor cleaning mode, i know Nikons do, which keeps the shutter open indefinitely

Wouldn't advise using a cotton bud either, let alone using a 30 second exposure. Cotton buds are made of tiny strands of cotton, if you're unlucky you could be forever cleaning your sensor.
Even my entry level Canon has the ability to manually clean the sensor by a setting in the menu, that lifts the mirror out of the way so you can get at it safely.

Or use B - but you've got to keep the shutter release depressed! If the shutter closes with a cotton bud in the way, there is a serious risk of damage.

Yeah Canon and Nikon have some work to do still dont they I have yet to need to clean an Olympus sensor.

I have had to clean my lens/filter dozens of times in one shoot.

What? Are you working in a flour mill or something?!

I wet-clean my sensors about once a year on average, with a rocket blower in-between.
 
I've opened the shutter with the Nikon setting and very lightly kissed the sensor with a dusting brush - Hopefully this'll do the trick.
