After this year of intensive equine competitions (with "abrasive" dust and sands all around, heavy rains), my 3 year old 70-200 VRII is completely wrecked.
Even though I cleaned it and took care, dust got in massively, rubbed everything and killed the AF motor, some inner glass, etc.
So,apart from addding a front protective filter (even if the front glass hasn't been damaged)..
What is the best way or product, according to your field experiences, to avoid these "dust/sand" issues (not during transport but in the field) and if possible, brands and links to specific products you've tested ?

That seems the most direct solution. But in a daylong handheld shooting it's not the most practical solution.
But I wondered if existed more "portable" and "alternative" solutions like gums, thermoretractable plastics films (not the zip loc, but very thin moldable with a comb) for the main parts and kind of "muffs" for the rings ?
There is Lens Coat, but I don't think it really covers the gaps. I would think the gaps around the rings would be the most vulnerable parts but also the hardest to cover while keeping the lens usable. (Although if you always use AF you could cover at least the focus ring and its gaps even to the point of not being able to access it.)
Let us know if you find a solution. Anything that would work for dust/dirt would probably also work for light rain, and I'd be interested in a more accessible solution than a rain cover for that use as well.
I just bought thermoforming plastic sheets today. It applies with a small comb and then stick tight to the object (but can be removed with fingers).
I'll make a test next week, and keep you informed.
Now for the focus ring part (admitting that the AF is on, most of the time in sport photography), I tought about a kind of tube with front and end sticking to the lens with rubber before and after the focus ring. A kind of "thickness duplicator isolated ring".
I admit it sounds DIY (and at this point it is) but maybe a thing industrially well done could make the job and look "corporate". I won't make it cos I'm dumb at DIY, but if someone wants to try ...
Note that after that dusty/sandy shooting season, I was surprised that the D4 has nothing at all. No sand, nor dust more that ususal inside. Good news for that awsome camera !
In extension, I'm a bit surprised that the 70-200 that looks tough and IS a pro lens suffered so much ...
Having taken photos in the Middle East where fine penetrating dust is a major problem, may I suggest a different approach suggested to me by the armed forces..... The use of two condoms! I know it sounds strange but it really works as the rubber is both strong and flexible, using two means that the lens can turn or be extended cut the end of each one with scissors or you can leave one complete over the camera side of the lens till you have to use it. This also works in very wet areas and can be used with a plastic bag over the camera. I would never recommend any paste or blocking liquid as this is a dust magnet
