I love the second shot, its clarity and dust trail. What AF mode did you use, and can the camera/lens combination follow a bike for some distance as it approaches?
Thanks

K3-3 and D-FA 150-450 mounted on a Manfrotto MH055M8-Q5 Photo-Movie tripod head and monopod
Shutter priority(TV)
ISO 100 – 200 (tried to stay at ISO100 but cloud would not permit the faster 1/1000 shutter speed from time to time so left it at 200 ISO a lot)
Continuous high (This is a bit excessive as in a few hours of practicing on these races I'd captured over 1750 RAW images. Need to try the medium setting next time)
Centre Spot AF Point (I need to try other options yet, but this is what I have done with my K-1 previously so using this as my start point)
AF Hold off (found the camera would hang up from time to time when using AF hold so turned it off. Approx 1500-1600 images out of the 1750+ were in focus so I'd recommend this approach and concentrate on keeping camera locked on the subject)
Back-button focus on ( the best option for action photography)
Highlight-weighted metering on (saw this on Eddie's video, didn't know what it was so thought I'd give it a go. Seems more effective than centre-weighted AE which is what I've used previously)
Shutter speed range 1/125 – 1/2500
The image you refer to was image 10 in a sequence captured where Taylah exited a right then came down hill to brake for another right. The sequence was 15 images successfully locked on as she rode towards me and I panned left to follow her into the second right-hander. This wasn't a fast part of the track but I also had sequences out of the final bend onto the front straight section which is also where the start line was located. My position for the images in this instance was off to an 11 o'clock position from the straight. The first images along the straight was a series of 13 in sequence, all in focus at 1/1000s.
The first start I captured was 11 in focus images before the lead riders separated and I failed to track one of them as I zoomed wider to allow for them getting closer to me. S/S of 1/1000 again.
Another series of in focus images of a rider coming out of the final bend and along the straight was 10 images in focus with dust from the riders in front between me and the rider for multiple frames. 1/1000s S/S again.
The slowest head on sequence was 8 consecutive in focus images at 1/160s along the straight. The sequence commenced with a miss as they came out of the final bend, there was then the 8 in a row followed by two missed, then another three before a miss as I started the panning into turn 1 which resulted in 5 more in focus with a miss for the last image.
The last couple of series with a front on aspect to them were at 1/320s S/S. The K3 Mk III and 150-450 tracked the rider through a dirt haze for 17 in-focus images. The rider wasn't as fast as some others but these examples should give you a feel for what this combo can do.
I need to work out how to get the best out of the camera and make those my user settings so this is really early days for me and using the new set up in this environment.
Previously I've been using the K-1 and this thing is way more effective with MX. I've now used it with the 150-450 and the D-FA* 70-200.
Apologies for the novel, but hopefully this answers some of your questions.
