Can anyone recommend a decent pair of binos for exercise and general use please, they don't need to be Gestapo strength. Cheers.
Nice one!JoseyWales said:I was walking down to the seafront with the kids and I clocked the headline in the Daily Mail. We sat on Ryde beach and I told them I could see a woman, through my bino's, sitting on Southsea eating a bag of chips and reading a newspaper.
" So what does the newspaper say" ? the older one asked with a certain amount of scorn. So I gave them the headline.
On the way back to the house, via the newsagents, I heard the youngest one say, " He's right, look at this Mxxxxx "
Example: 8x30. 8 is the magnification. 30 is the diameter of the objective (front) lens in millimetres. Bigger lenses allow more light through.ugly said:Ok, objective lense, nearest the object you are looking at and ocular lense nearest the eye. Now if you are 8 x 30 then the ocular lense is an 8 x mag and the ocular is 30 times. There have been tests done that prove that average human eyes can only use the light entering something like a 7 x 40 lense set up, hence most fixed mag sporting scopes are around 8 x 56 to allow the maximum useable light and then some.
Hang around Ex_Stab will give the techie lesson shortly! What I have written was gleaned from lectures on optical instrument manufacture at the IWM.
