Custom Function I: Exposure, ISO Expansion. Turning this on will allow the selection of "H" ISO (25,600).
Hope that helps. Don't be too optimistic about the results!
Wow, Wow, Wow---Thanksss, Dear PhotoAviator. That Solve the Problem for me, Now= It work too.
One more Question, Sir.
For My Only Manual Focus of My Lover Canon Lens TS-E 24 MM F/ 3.5 L MK II, When I use with my 5D MK II. I set 1 point at Center of Viewfinder, And When I rotate the Focus ring of this Lens, When in on the right Focus, The Focus Block will change to Green color and Plus the Beep sound.
Well I try this Lens with my dear EOS-M, But I can not get the Green Color focus block and No beep sound. May be not work with this Tiny EOS-M, But I must ask You first, Is it Possible or not ?
IF, Not, My eyes are so bad, That Mean I can not use this Beautiful Tilt and Shift Lens with my EOS-M.
Thanks you, Sir.
Here are the photos of ISO 3200 and ISO 25600 at minimum light, almost dark.
