What is the difference between the old and new finish..

On the Sigma 50mm 1.4?

Debating if I should buy a new one instead of a used one. But at the same time there's a lot of the old finish sigma for sale. I can't tell the difference at all. Can somebody explain to me what that is? Thanks!

The new one is a smooth, matte plastic finish. The old is referred to as the "crinkle" finish, and it's not smooth plastic. It's rather hard to explain, but I've never had a problem with it. In reality, there's really no difference when using the lens.

Old was cheap looking, it's the one I had. New one - IMHO - looks much better.

Thank you guys. That's all I was looking for.

The old finish showed marks easily and some people had the coating flake off after time, I never had this problem with my old 70-200 when I had one a few years ago, but it seemed to show every fingerprint and dust/dirt mark possible!.
The new finish is simply a 'normal' matt/silk plastic finish.

I personally prefer the new finish of my 30mm f/1.4.

I prefer the "new" finish too, but there really isn't that much of a difference.

i feel like the old finish looked rugged...the new finish looks clean...check it out for yourself:

The old one eventually flakes off
