Can anyone narrow down which Canon lens this is ?

[mangurian]

There are many (I think 6) EF 70-200mm varieties. I have 4 images of the lens in question and none of them show the specific model.

Can anyone help ?

Read us everything that's etched or printed on the lens, especially what it says around the front rim.

It's a - EF70-200mm f/2.8L USM

Thanks

That lens has been in continuous production since 1995. You should be able to find a date code on the lens mount area if you want to know when it was built.

"There are many (I think 6) EF 70-200mm varieties"

I only know of three. As Robert asked, what does it say on the front of the lens.  That is which model it is no matter how many versions exists.

[MikeSowsun]

There are FOUR f/2.8 versions and THREE f/4 versions.

it's the non IS f2.8
