18-105 and 16-85

[Peppe]

I just had a quick look at the specs. (18-105mm, 16-85mm). They have different construction:-
18-105mm: 15 elements/11 groups, 1 x ED element, 1 x aspherical element
16-85mm: 17 elements/11 groups, 2 x ED elements, 3 x aspherical elements
I assume that ED and aspherical elements are more expensive to manufacture than standard elements.

The 16-85mm should theoretically perform better than the 18-105mm with regard to issues like chromatic aberration, however I don't know how either lens performs in practice.



Cheers.

Thanks Fillum (btw, love your name, i know someone who can't say film he has to say fillum!!)

When you put it like that, it makes a lot of sense

If you can find plenty of the folding stuff i'd go the straight 85mm and look at the 17-55mm as well. this would give you two superb lenses that will last a life time. And yes, quality and workmanship cost more.

Unfortunately the "folding stuff" is pretty well accounted for!!!

But this will be a great kit that he can build on in the future once he knows what kind of lens' he'll need
He may even buy (in the future) a 24-70 and a 70-200 then i can (hopefully) borrow them
