I'm hoping someone else has had this experience or there is someone else who has seen this behavior. I was shooting with my DP1M this morning - a grey morning. I had the histogram display on and was shooting at 200 ISO in A mode. While I was adjusting the histogram to the right I got highlight blinkies! They worked on about 10-12 shots and then no longer after I switched my camera off. This camera doesn't have that feature... was it the last firmware update, I wondered? My attempt to research or replicate this behavior have all come up blank. Has anyone else seen this behavior on their Sigma DPx?
