Grain Bins at Dawn (DA 15 limited)
Both shot with my (still functional) K-01. Sometimes when I turn it on I get a black screen, but if I shut it off for a minute or two it seems to remember its job again. Funny that Flickr thinks that this is the HD DA 15 limited, but mine is the old fashioned SMC version of the lens.
Love the grain bins with the sunstar.
As for your issue, make sure your battery contacts are not dirty/corroded by air (oxygen), time and use. Cleaning them with isopropyl alcohol and a swab can help. Some graphite from a pencil afterwards is useful, too. Just brush off any excess.
My K-5 started acting up and this eliminated the problem. Old batteries can be a source of inconveniences, too.
