Link to the lens:

I read about this lens that there is no <<35>> graved on the barrel for the lens made in Canada.

<<Black aluminum anodized, Canada, no "35" on barrel, new formula from #2166702
Black, Canada, no "35" on barrel, no infinity lock
Black, engraved "35" on barrel>>.

In this case, we have <<35>> on the barrel of a lens made in Canada.

I don't know what to think.

Any advise appreciated
