Description
This is a lens hood for the Helios 44m 7 58mm f2. I use it on my Sony a6000 with a speed booster adapter. This gives me the full field of view of the lens not a croped view (plus it gives me extra stop). So I designed the hood with the following in mind : To work with the full field of view (no vignetting) You can put it upside down to make it compact - store it with the lens. Note. The length is for a Helios lens with an adapter or speed booster. If you have the lens with no or smaller adater you cant pout it upside down .
