Here is what works best for me for high-speed motorsports where the path of the object is known. I use continuous AF and burst mode shutter. As mentioned, start with your body wound-up and then un-wind as you pan. I don't like the method of pre-focusing on a spot and then firing when the object appears in frame because the shots end up being very static compared to more dynamic panned shots. Besides that you need a faster shutter speed if you don't pan. The dragboats below were traveling 200mph+/- in a straight line in front of me. I used a SMC F 80-200mm lens at 200mm (cheap-o lens). I shot most at 1/500 sec but 1/350 sec seems to be the magic shutter speed for the pans at this speed. I'll be the first to admit (and complain) that Pentax AF is pretty poor but my DS did a great job in the overcast daylight in continuous AF mode. You can practice panning with cars on the road. It's not hard at all really, kind of like shooting skeet.

200mm F11 1/500




200mm f8 1/350 <--- this worked best with panning




200mm f9.5 1/500

Nice stuff. I agree your method works well most of the time, but if you have an object in motion moving toward you, or away from you (even at an oblique angle) the AF has a very high chance of being incorrect, particularly onthe DS or K100, and particularly if you're attempting to use a wide open aperture, thus the need to prefocus. Obviously that is much more difficult if you don't have a clue where the object is going!

Standard panning shot:



The "latest cool thing" in moto...only a small portion of hte bike/rider being tack-sharp:



Result of prefocus (K10 CAN NOT keep up with objects moving 50 mph 4 feet away. Hopefully the HSM lenses will) :

Oh MAN! You're gonna' make me dig out the EXIF for that lol.....

OK.....shot with my K10, full manual mode, ISO 200, 1/180 @ 5.6, w/ my Sigma 100-300 F4 APO EXDG.

It was a really overcast day. That photo is completely untouched other than downsizing and uploading (White balance seems a touch off to me).

EDIT: Sorry, I forgot to mention it was shot at 160mm.

haha, figured I'd make you work for bragging rights on the pictures!

Again, very nice pictures and that is quite a good combo. The Sigma 100-300 was another lens that had caught my eye (yep, I've officially been bitten by the lens addiction).

I think I'll just shoot some landscapes of the track and have our compositing team here comp in some F1 cars heh

LOL, Can I use them too? It'd make getting that "perfect" shot alot easier!!! LOL, I like the 100-300 alot. IT's my go-to lens for most of my moto shots (mostly because my 70-200 was stolen!!!). I am quite sure that will change when the *s come out though!!!

Haha, I'm sure you could borrow a few comp guys here to make the "perfect" images Heard really great things about the 100-300 and not a bad price, sucks to hear about your 70-200 though man!

The HSM on the upcoming 2.8's is only usable on the K10D am I correct? It was mentioned earlier but a smaller chain here said the HSM would work on the K100D as well..

My understanding is yes, only the K10. I don't believe the K100 has the hardware to make it work. OF course, I'm not tech expert, so someone else may have more input.

28-300mm F3.5-6.3 DG Macro (62mm)

Hi guys I shoot alot of motorsport here in the UK.

I konw this is too late for the Canadian GP but may help others.

I have 2 *ist DL's one with 28-300mm F3.5-6.3 DG Macro (62mm) fitted good all round lens and the other with an old Sigma 400mm lens fitted. With the old 400mm lens fitted on a digital body it turns it into a very nice 600mm lens without losing a stop The 28-300mm F3.5-6.3 DG Macro (62mm) lens is very good for motorsport it is quite fast and very compact and light.

Have a look at the photos in my msn space link below.

This is Dave Kimber
