Originally posted by Lord Lucan Thanks for the replies. Perhaps I had heard someone talking about their Limited Edition outfit and they did not realise that a battery is not normally supplied with the grip.
My thinking is that if my D-Li90 battery expires in 10-15 years time, and they are no longer obtainable for some reason by then, I would be able to continue with AAs in the battery grip. Having said that, the Li-ion battery in my K10D was still going strong after 12 years, and the D-Li90 is not unique to the K-1 (AFAIK it also fits K-01, K-7, K-70, K-5, K-5 II) so there should be a demand for it for some time to come.
If you buy a normal Black coloured grip, no battery is included, BUT if you buy the K1/K3 Limited Edition cameras that come with the grip, 2 batteries are included in the purchase.
That was what I got when I bought the K3 Limited Edition camera.
