So this is my 2nd attempt at reproducing the mirror flap issue. Could not reproduce any odd behavior.
Run #1 ( 03/16/2014)
-Battery almost depleted (only 1 bar remaining)
-Activations ~700 within a span of I think 3 hours probably.
-300 of above activations happened using the Time lapse menu in non-live mode.
-Lens: DA 50mm 1.8
-TAv mode, AF-S, Center Point focusing, SEL1
-At the end of this test run, the battery depleted warning came on and the camera shut off.
-Had the battery grip attached which contained Eneloop and Harbor Freight AA batteries.
Run #2 (03/17/2014)
-Battery fully charged, left it charging well until the green light on the charger went off for quite a while.
-Activations 400 in all for this test, overall shutter count= 2702
-All 400 activations happened within a span of only 1 hour.
-Contains 2 time lapse with 100 pictures in each time lapse.
-Rest all were AF Tracking Test shots with about 100 shots in each sequence.
-Lens DA 18-135
-P Mode,AF-C, AF-9
-Battery level was still showing full i.e all 3 bars.
-No battery grip attached.
The camera worked flawlessly even after that. Took a couple of shots in AF-S to verify everything is ok.
I must have burnt through at least 1500 activations trying to reproduce this mirror flop/machine gun/overrun issue. It refuses to manifest. I will purchase the extra 2 years Pentax warranty anyway, for 20 bucks you can not go wrong! Any more shutter activations towards recreating this issue are not worth it IMO. I am just gonna keep shooting and have fun with my K3. :touches wood:
