However, the K1 isn't a sport oriented camera. You got fixated on the K1 slow SD card writing and carry on with this problem for the GRIII. And the GRIII is even less sport oriented and has a 24Mp sensor instead of 36Mp (less data to be transferred). And you never used the GRIII, you don't know if you have to wait or not for SD card being written, you don't know how fast is the internal 2GB memory writing. So, yes, memory card speed and buffer size are considerations no to be forgotten. But for the GRIII as a street camera, I believe that UHS-I is appropriate. You could however keep the SD card speed complain/objection for when Ricoh would release a sport oriented camera or another 45Mpixels full frame for weddings.
biz-engineer the only thing holding back the K-1 from being a "Sports" camera is the UHS-I bus. The slow SD bus holds back the K-1 from being taken serious by pros even though the K-1 delivers the best image quality and with the K-1MKII it is by a long margin. I can not imagine trying to shoot a wedding with a camera that is taking 15 seconds to flush out the buffer. Am I fixated on the slow SD bus? If that is what your perception is feel free to dismiss what I say. It is not my experience the waiting for SD card writing(entirely due to UHS-I) with the K-1 it is every K-1 user.
We have all waited really since 2013 for the next generation GR. The GRII was an update. So in 2019 with the GRIII I would expect Ricoh would want to release a camera that will perform to 2019 standards instead of UHS-I which is 2010 standards.
So biz-engineer we can put you down as being happy and okay with waiting 15 seconds for the full buffer to clear with UHS-I. You prefer that instead of less than 5 seconds. Which by simply moving to UHS-II is delivered and solves all the lag and slow operation of the camera.
