If you want to be super precise and check, shine a bright light through the eyepiece with the camera close to, parallel to, and focused on a wall. It will project the groundglass onto the wall large enough to comfortably measure. It's also the best way I know of to get really precise framing charts done in checkout, BTW.

thanks chris... but are you talking about a flash light, or something like a hmi?
One of those xenon bulb type flashlights or one with a bright LED will work fine. A medium focale length lens wide open is good.

To me, this is the 1.85:1 but the superimposed marking lies somewhere arround 1.50, quite unusual.

As I posted guessing it is 1.50:1 which will come to roughly equivalent of 14:9 and remembered the UK Dp ( location shooting in Nepal ) composing for 14:9 aspect ratio as he said most of the UK television stations demand for the composition within 14:9 as the safety for both the High def TV and 4:3 tv.
with best regards,
