Petal hood or round hood?

[Kofman13]

I have a sigma 28-70mm f/2.8 i got used and it did not come with a lens hood and i really need to get one. I cant find a sigma brand hood at adorama or B and H.. ( the original sigma hood is a round one). adorama has a 77mm filter thread PETAL shaped hood that would fit on my camera...would that work well? or do i need a round one

I would search for a lens hood that was designed to go with the particular lens. Using hoods that are not meant to be use with the lens will lead to problems (lens flare for instance).

Will the front lens element rotates with AF?

Will the front lens element rotates with AF?

yeah, its not internal focus

I am pretty sure there is a difference between internal focusing and when you focus the front elements rotates.

Example:
50mm F/1.4 front element doesn't rotate, but does extend as you focus.

EF 70-200 (any version) front element doesn't rotate (same) but also doesn't extend as you focus.

 

[Kofman13]

ok, my lens does not rotate, it just extends

Ok, so which 28-70 do you have?
28-70mm F2.8-4 DG
28-70mm F2.8-4 High speed zoom

They only show these two lenses and the link I posted lists it as being compatible with the 28-70. Perhaps you should call Sigma.

Get this and call it a day bro

If I were you, I will pick up the round one since you said the original one that shipped with the lens is round.

Certainly am; I have a Birman, a Norwegian Forest & 4 of indistinct origin!
