Any way to check on Sigma lens how many times it was used?

I know for camera bodies you can find out how many activations there are.

For lenses I was wondering if you could find out how many times it's been activated? Specifically Sigma Lenses.

Thanks

No. If you're looking at a used one, unfortunately you have to rely on the honesty of the seller... One easy test: check the focus ring to see if it's really loose or hanging off. If it is, it's been used *too many* times.

Number of times a lens has been "activated" doesn't mean anything relevant. With proper care, a lens can last *decades* regardless of the number of pictures taken with it.

no, and why would you care?

Buy brand new. Problem solved.

Even if this information were available, it wouldn't tell you much other than how many times the aperture iris has been actuated.
