Re: Spaltzer, you have a valid point.

I just compared my GF3 and the 14/2.5, to my E-M5 and the 14/2.5, in the same room.
The GF3 keeps maximum aperture up to 1/640, before increasing it.
The E-M5 closes the lens to f3.5 when it reaches a shutter speed of 1/125.

Thinking that it was the camera/ lens combination that was causing it, I tried the same test with my 17/2.8 and 45/1.8. Same results.

Next, I took my wife's G1. With the 14/2.5 lens, it switched to 2.8 at 1/125 and to 3.2 at 1/160
Something is wrong with the GF3 Program algorithm.

Many thanks Jeff for investigating this and posting your results!

Does anyone know how to report bugs to Panasonic?
