lenses that are prone to dust are prone to dust because of a design flaw.

nothing to do with third party lens or not.

All lenses are prone to dust. When you switch lenses, dust gets in. When you zoom in and zoom out, dust gets in. When you focus, dust gets in. Even when you put lens in a dry cab and not use it, dust will get in also.

Specifically, one-touch lenses tend to be more prone to dust getting inside the barrel.

Lenses which are not 'sealed' as compared to 'sealed' lenses like some of Canon's L lenses are more prone to getting dust inside the lens barrel. Not all L lenses are 'sealed'.

Tilt shift lenses, in theory, are more prone to dust, but in practice, it doesn't appear to be an issue unless one is shooting in very sandy/dusty conditions.

Some lenses with multi-section, extendable barrels MAY be a little more prone to dust as compared to a single or two-section barrel design.

In many cases, a lot depends on the physical tolerances of a lens, it's physical design (the term 'design flaw' may be misleading as various parameters have to be kept in mind where lens design is concerned, and a balance of compromise usually has to be made) and how 'tight' the felt buffers are.

As some have mentioned, dust is everywhere and you'll be fine even if some dust gets into your lenses. Choose better sealed lenses if you're going to shoot in environmentally challenging situations. If not, don't bother.

Hope this helps.
