In my original post, for 'cropping' please replace with 'framing' - better to have plenty of space around the frame than cut something off at the edge of the frame.

I'd go for a wide-angle in the 15-20mm range - more depth of field and more scope for cropping in a chaotic environment, possibly using flash if that works for the riders. If you're close (within 15 feet), AF tracking probably won't be fast enough no matter which lens you go for.
You could well be correct! I always take my 10-20 Sigma when I travel - it all depends on how close you are/ need to be/ are forced to be!It depends how close to the race you'll be (I'd imagine you could be very close), especially the bit about 'coming at me and whilst they move past at speed'.

I did some cyclo-cross photography a couple of years ago. I was able to be no more than about a metre away on some parts of the course so I would suggest for tight shots something like a wide angle zoom- I used a Sigma 12-24 on a Samsung GX20 for passing shots. For more distant action I used a 50-200.

OTOH, most 1.4x T/Cs are NOT "Pz" types and won't allow autofocus with such lenses!
FWIW, there is a "Pz" T/C here this morning (it's not cheap, but that's about what they sell for nowadays, and >twice what I paid for mine about 5yrs ago!)stu62 wrote:

The converter needs to be the type with "Pz" (which were designed to operate with the old Pentax power zoom lenses) in the name, because only those have the contacts and connections which can now operate the DC focus motor in the 18-135 and the HSM motors in the Sigma HSM lenses (I have both types of lenses and can confirm this to be the case).if you are quick there is a 18/135 in the clasified on here for £150

K-3 II, K-3 and a K-70 from SRS (having now relegated the K-30 /"K-50" to a backup body), & some Sigma and Pentax lenses (and a lot of old 35mm gear!)
