Hi guys,
I'm looking for an 82mm metal screw-in hood for my Kaleinar 3B, which is a 150mm f/2.8 Pentacon-Six medium format lens. It has a ridiculously huge, probably uncoated front element, and it definitely needs some glare protection.
On eBay I see two different 82mm "tele" hoods.
One is pretty long, and
one is a bit shorter. The long one says it's for 200mm lenses and up, but since the equiv. focal length on the Kaleinar is 225mm, I'm not sure if it's the one to go with or not.
Can anyone tell me if "effective focal length" is a consideration when choosing the right hood, or whether I should just go with the shorter one?
Thanks!
