the widt between lenses is width between THe Center of the objective lenses. not the rim of the tubes.
if that width is also same, I adimit I was wrong about width between 10x42 EL and 10x42 sf
if the distance between two bino are same. the more distortion ocuured in SF 10x42 may have affected the 3d rendering.
comparison between el 10x32 and sf 10x42
why I use 10x32 el's photo is that EL 10x32 has much similer fov to sf 10x42 (68.5 / 68)
in digiscoping, the wider the apparent fov is, the more amount of distortion (pincusion and barrel) is likely to get exaggerated by the camera lenses.
10x32 el amd 10x42 SF has almost same fov, so exaggeration also will be similer. so you can see the difference more cleary.
plus, 10x42 el does seem to have less distortion then 10x32 el.
