Hi Guys,
I recently bought a Sigma 75-200 f3.8, i'd been hankering after one for a while and it popped up on eBay. Sadly it didn't come with the hood so I've had to find one myself. I did a search for telephoto lens hood with a screw fitment of 55mm, the first one I received was too short (wide angle). I've just got a B+W one through the post today which is 55mm and designed for telephoto lenses, the only thing is it looks odd to me - it doesn't get much wider like a normal hood does (see pic below). However the hood doesn't seem to appear in the frame. Do I have the right hood here or not? is it actually going to work? if not can you please link me to the correct one to buy.
Thanks,
Alex
