I presume it means that it bears the logo (in this case sigma) but is not officially made by them.
sometimes very hard to prove.
but your talking €80 – €90 for a telephoto lens made by a recognized makerof lenses.
Am i mad to get one of these?????
now you’re tempting me!!!! did you ask the seller a question to see if the listing is right?
although if you check their seller feedback, about 12 down, the same item was sold and positive feedback was left.
I have the APO version of this and love it… but from what I read there is quite a difference between the non-APO and the APO one. I paid £75 for mine (used), so £70 for a starter still seems good value, but personally I would pay for a used APO version (again only IMO and from reading around….I’ve never used the non-APO one).
