Originally posted by mbceft Shooting a motorsports event with the K5ii yesterday reminded me of the patience needed and the expected missed shots while waiting on the buffer to clear, even in single shot mode. I would be curious to see how the buffer on the the K3M3 fairs in this regard. I am certain it is much faster especially in the UHS-II slot. I guess my question is can the buffer clear fast enough in single shot RAW to not have to wait on it if shooting at a reasonable pace?
Even thought I never had the chance to do so with a K5II I did with a Kr, K5, K3, and K3-II and I feel you. Even on the latest post I made about ELMS, there is some images I was shooting at a corner where it was almost impossible to pan a car with the right focus on the K3-II with a fast lens (i mean a fast AF lens) as the Sigma 100-300mm F4. My mate had his D500 there with a regular 70-300mm f whatever high to f whatever higher and let me try, that was suuuuper easy to get in focus almost every single time. So yeah that is a good point. Even some years ago shooting on a Canon 7D MK-I and a regular lens (a 35-350mm lens from Canon) at a 24 hours race at night here in the same corner I wanted to get the brakes red and some flames and it was super hard to impossible to achieve with my K3 + Sigma 100-300mm f4, but with that Canon it was quite simple to do and on focus. I mean the Pentax was not even able to work with that. (on a side note I hate those Canons, they are big, all plastic and menus and names are weird to me).
So yes if the K3-III does a proper job, that'd be a superb step forward.
