Using K-3 to shoot motorsports

I am a proud owner of a K-3 (just picked it up off eBay) and was wondering if anyone had tips/tricks for using it to shoot motorsports. It's a HUGE step up from my *ist D, so any help would be appreciated. Any suggested presets or initial camera settings I should be working on?

Hi, and welcome from the UK! The K-3 is indeed a big step up from the *ist D; I went from a *ist DS to the K-5 and then to the K-3II, and there was a learning curve even from the K-5. The 24mp sensor is less forgiving and I found that it requires the use of higher shutter speeds to get sharp photos. I don't shoot motorsports so can't help there - I'm sure there's someone here who can.

I have used K-5, K-3 and K-1 for motorsports and all of them are very capable. I think settings depend on where you are and how you are shooting. I tend to do a lot of panning after pre-focusing. The lenses you are using can make a huge difference too. My favorite ones are the Sigma 70-200 and 300 2.8.

I have the Sigma 28-200 which is my go to as I mostly shoot karting and close to the trackside. For longer stuff, i'll use my Sigma 170-500.

Thanks for the input everyone.

There's a lot of technique involved. Obviously good light with high shutter speed is a big advantage. But shooting from the side whilst panning and shooting from the front and making sure you nail focus are very different skills. I would use Continuous autofocus for the latter, if it works well with your lens. If not, manual focus on a particular point and waiting for the car/cart to reach it might give best results. Of course, if light is good enough to stop down a bit, it will help your focus.

Good luck. Looking forward to seeing some example shots from you here on PF.

the little experience I have had

I used panning techniques and what I call location selection:

get to a corner/curve and catch the vehicle as it slows to negotiate the corner/curve and accelerates to come out

My 2 cents on this:

K-3 is quite excellent with certain focusing aspects. It has a range of options though, and these aren't very well detailed in the manual. (Pentax weakness here, providing functions/capabilities, but not explaining how best they should be used).

I use the focusing mode that allows you to select the object to be tracked using the centre point, and then controlling how far outside the centre it will be tracked.
Others will have the detail (sorry I'm away from my camera right now to check) but it works quite well.

For panning turn off the shake reduction, and it's a bit easier to pre focus the distance to the track, and then pan on there in manual focus.

Carting / racing allows for prefocusing a bit easier, as you know where they'll be passing by. Whole scene could be in focus (f11 or more) because the background will blur with the slow shutter speed.
I think doing things like this, removing the possibility for failure, is key to achieving successful results.

I shoot a fair amount of motorbikes and birds with a K3 (mk1) and novoflex 800mm follow focus vintage lens, I pick an interesting place for motorbikes and pre focus and then pan with the action.... seems to turn out a good amount of keepers....

Depending on the light available, testing for the most appropriate shutter speed, F stop and ISO will show you which settings will be accommodating. Of course you are going to want use the most appropriate shutter speed to catch the rate of motion of the subjects. Also, as has been mentioned earlier, you may want to pre-focus on an area if in case that is where you are going to attain your shot, or just follow the subject the best you can. You may want to give yourself a little extra field of view to be able to track the subject appropriately without it running out of your view too quickly. If the subjects have certain areas that show nice contrast, you may want to focus on them to attain AF easier than trying to focus on other more plainly looking features. I have a Sigma 150-500 DG OS for Pentax that I presently have on my Pentax K-5 IIs, and shooting moving objects is not difficult. I usually use Single point (center point) AF to track subjects, and also use Continuous AF mode. If the Sigma lens you have has OS (optical stabilization, switch on side of lens), you may want to make sure that you have it turned off if you are facilitating the use of the SR feature on the K-3, and the other way around if you want the lens OS on, and the SR off on the K-3. That way the two systems do not conflict with one another.

Good luck.

I've done a bit of it and it's not as easy as it looks. Very fun though.

First advice
--
AVOID CONTINUOS TRACKING.
--
IF POSSIBLE - ALWAYS USE LARGER F NUMBER - LIKE f-6.7-f11
--
DO PREFOCUSING.

--
Leave buffer clearest as possible. ! AVOID RAW.

--
HIGH BURST CONTIONUOS SHOOTING - in short intervals, of 5,6 pics in a row.

--
If you use AF - put your thumb and press Magnifier button ( I think you must assign it ) to avoid new AF between the shoots, if you already nailed your focus,

OR
switch to manual, if you don't want to keep pressing that button every time you don't want losing your time, to nail AF spot.



------------------------------------


Panning technique - have nothing to do here, because you're begginer, so I will avoid explanation on that subject

Panning is a technique that can produce amazing results (if you perfect it…. or get lucky) but is also one that can take a lot of practice to get right.

The basic idea behind panning as a technique is that you pan your camera along in time with the moving subject and end up getting a relatively sharp subject but a blurred background.

This gives the shot a feeling of movement and speed. It’s particularly useful in capturing any fast moving subject whether it be a racing car, running pet, cyclist etc.

I’ve found that panning seems to work best with moving subjects that are on a relatively straight trajectory which allows you to predict where they’ll be moving to. Objects that are moving side to side are challenging and can result in messy looking shots as the motion blur can be quite erratic. . . .
Mastering Panning - How to Photograph Moving Subjects

a simple search comes up with various articles and videos explaining the technique

https://www.google.com/search?q=panning+photography&oq=panning&aqs=chrome.5....hrome&ie=UTF-8

practice, practice, practice

practice can be key to so many things

and with digital, as oppose to film, you know the results quickly

The K-3 is great for motorsports. I've been using it for several years, its fast, easy to use, good iso range, and decent on battery

I don't do motorsports, but shoot a lot of planes, I've just discovered 'Expanded Autofocus'. This is under the info button and gives a fair number of options. My keeper rate since using it has increased greatly, also on an ovecast day auto iso works well.
