There isn’t a simple “actuation” life rating for lenses like there is for shutters. Lens lifespan depends much more on build quality, environment, and how the lens is treated than on shot count alone.

In general, a properly cared-for lens can last a very long time—often longer than the camera body. Many well-made lenses are still working decades later. But cheaper kit lenses usually use lighter-duty parts and often lack weather sealing, so they’re less tolerant of freezing, dust, vibration, impacts, and similar stress.

So 10,000 shots by itself should not normally wear out a lens, but harsh use absolutely can. In your case, the freezing and motorcycle vibration/bumps are more likely contributors than the number of exposures.

Higher-end lenses from major brands tend to last better because they use sturdier materials, tighter construction, and sometimes weather sealing. Any lens can still fail unexpectedly, especially if dropped or exposed to rough conditions.

Bottom line: lens life is variable, but good lenses can last many years. Entry-level lenses may fail sooner if used hard, while better-built lenses generally tolerate abuse and age much better.
