I own the KP for three weeks. Got it mainly for walkarounds, street and hiking. But it also proves to be very nice for macros. With this camera Ricoh-Pentax offers us something that can be comared with compact Fuji- and Oly solutions also offering compact cameras with compact grips.
I like the grip solution very much. Until now I use solely the preinstalled one. For me really no problem in handling. If you are interested in what I think about it, you can read it in this
post. A thing of how we use different tools.
Got two spare batteries (Ansmann 7.4V/1100mAH/8.1Wh) that seem to work well. So, also no problem.
In short - IMO a great and not too heavy camera that I love. It’s going to be a hard competition for my K-1
