I fell for the K-s1 preorder due to its size, but later revelations showed me that many of the features I use on Pentax bodies were not included.. so I let that preorder go. The KP does not appear to have those issues (at first reading) and it would be the best Pentax I ever used.. though the K3ii is pretty much a draw since I seldom 'do' caves at midnight
Two batteries should be good for 800 shots, so two smaller LI190s are a near match for one bulkier LI90.
Still, the budget rules - and my six month, oft-delayed refinance is either dead & buried or about 10 days from completion. Is today an even- or odd-# day?
I will watch with enthusiasm however, since that cost almost nothing!
