Seeing your post I decided to have a google for secondhand MKIII 70-200 f2.8.

Sadly there doesn’t seem to be any available at what I would consider a reasonable price :((

I also looked at the price for a EF f4 MKII and similarly none at a price I think was reasonable.

I did see I could get a new RF 70-200 f4 for nearly the same price as a new EF 70-200 f4 MKII and even some ‘mint’ secondhand ones.

So on those results I’ll probably go for the RF f4.

As regards sucking dust, I had the original EF 100-400 MKI, the trombone. People were saying there would be dire consequences as regards dust. I had that lens for some time and never suffered any significant dust problems.

Any lens which has a moving mass inside whether moving totally internal or externally air will be moved.

Travel on any underground system and you can feel for yourself, that even a poorly fitting piston will move air quite effectively.

I wondered why the ball kept getting bigger, then it hit me.
