Max. approx. 8.3 fps, JPEG ( L: ★★★ at Continuous H): up to approx. 60 frames, RAW: up to approx. 23 frames
I seem to have got more than 60 frames using JPEG. With the ATR I got 27 frames on RAW. With the 717, exactly 23 on RAW.

Which means that after the buffer fills the FPS goes down to less than 1 per 2''?
That's not what I think I'm seeing. The images seem more evenly spaced. I don't think I got much over 2 fps (and the average was 1.8 fps). I suspect that to get 8.3 fps you'd need no AF activity at all and a very high shutter speed.
Quote: I'm also more interested in your future test with RAW files
I did test RAW files, noted above, but I need to do more. It looks like the approximate 23 image limit is true. I think what disturbs me more than a 23 image limit on continuous with RAW is that what seemed to happen in the past if I took a burst of say eight photos, then took my finger off the shutter release, there would be an annoyingly long delay before the camera would take more photos, even though I didn't fill the buffer.

It's a great lens for travel because it's more company than the older 55-300 which I used in the past and focuses much faster. The resolution and shadow rendering isn't a patch on the DFA 150-450 but then it's also a fraction of the cost. You just need to stop the PLM down on the long focal lengths to avoid vignetting.
