Pentax K-5 flash slow-speed sync with Pentax-A lens
Has anyone else noticed an issue when using Pentax-A type lenses on the K-5 where the shutter will not go below 1/180s in Av mode with the built in flash using Slow-speed sync?
Using "DA" type lenses the shutter properly adjusts down slower than 1/180s in Av mode.
Nothing in the owner guide suggests the Pentax-A lenses should limit functionality with the K-5 in Av mode.
The Pentax-A lens with the K-5 in Manual exposure mode works fine. Metering is correct for a given scenario just as with my DA lenses. I normally use manual exposure anyway, but I do find Av with slow-speed flash sync very handy for indoor snapshots.
Just curious if anyone else has run into this issue.
Thanks.
