RE: SCOPE OBJECTIVE 40mm vs. 50mm ? ?
I’ll just add a little to this thread. I have 2 Swarovski scopes. One is 3-10 x 42 mm and the other is 4-12 x 50 mm. Both are excellent scopes. Do I see a difference between the 2 at low light. So little it’s not even worth mentioning for my eyes that is.
Now, I made a comparison with some other scopes I have/had one evening. All scope were set at 6 power .One was a Leupold Euro 3-9 x 50 mm with a 30 mm tube. Did it do better then my 42 mm , not at all .The 42 mm was still better in low light because of better optics. As far as I’m concern the quality of optics is more important then size of obj. lens as I previously mentioned...
