Its outer diameter size is about 45mm.
I bought Eagle Optics cover small, but it is a little bit tight.
Could you give me the cover size of Swarovski EL 8X32 binoculars?
I am considering using EL 8x32 cover with Nikon 8x32 SE.
A: Unfortunately, the 8x32 EL objective lens covers won't fit the Nikon SE. They are designed to fit inside the objective lens barrel rather than around it. This is done to accommodate the tether and allow it to fit on the front barrel of the EL which is very short.
I couldn't find another good match for your SE other than the size 5 flip covers offered by Bushwhacker.
