One big question for K3 + K3II users with the new Pentax 150-450 zoom (if anyone here can answer that).

Do you use TAv at all with this combo?

I started out years ago using TAv but ran into trouble with overexposure from time to time so now I always use Av, Auto ISO set to 100-8000 and FAST and this gives me @450mm 1/1000 at its slowest unless the ISO hits 8000 which it pretty much never does the way I shoot. The gain by doing so over TAv is that if the light becomes really bright and I was using TAv 1/1000, f/6.3 the ISO may hit ISO100 and the images becomes overexposed. Using Av the shutter speed will become faster and give me correct exposure.

Did that answer your question?

Thanks for the OP starting this thread, and the ones that bumped it! I've got a K3 coming; and this thread is full of good information for me to read thru. I've bookmarked it!

Yes it does, thank you!

Thanks for starting the thread jpzk - I am most interested in learning how others are using the K3 AF settings.

I have used my trusty K5 over the past few years to shoot my kids playing junior basketball and while I have managed to get 100's of treasured shots but there have been many hundreds more that have been trashed due to focus not being right (or close to right). The K3 promised a significant upgrade in AF capability and, in summary, I am very pleased to find a big increase in "in-focus" shots. How much better? Subjectively, I guess that with my K5 (& DA*50-135mm) I would get about 25-50% acceptable focus whereas the K3 produces 75%+ acceptable and about half of these really sharp. The other noticeable improvement is that the "18. AF Hold status" also works a treat at basketball producing more potential "keepers".

With IQ, I initially thought the images were a lot grainier but I now think it is not so bad as I am cropping more heavily than previously and bringing out more grain. So probably there is a bit more noise than the K5. Overall though I am getting many more "keepers" and for my shooting the K3 is a definite step-up in technology over the K5.

I couldn't say if the DA*50-135 focusses more quickly on the K3 than the K5 - there are too many other AF variables that have also changed moving to the K3. The K3 tracking has no problem locking onto a player running towards the camera and holding the focus for the length of the court (and also having other players & the ref passing between the camera and the subject and keeping focus!). I read many comments on the forums that the DA*50-135 is the slowest focussing Pentax lens and not recommended for action/sports but I have found it performs quite well!!?? I purchased it specifically for basketball because it is F2.8 (basketball is fast action in usually poorly lit stadiums) and the zoom range ideal for sideline shooting (most shots I take would be around 70mm). I suspect that the long focus travel between 1m -infinity is slow but within the range it is very quick, ie if you are near to focus at the start it is very quick to lock on and can easily follow a player running full speed towards you. I think the inability of the K5 to track well has not helped the reputation of this lens. There are probably other lenses that are quicker but my view is that 50-135 can do a good job.

I photographed 7 matches at the Dandenong/Eltham junior basketball tournament over the Australia Day long weekend in January (this tournament is purportedly the worlds largest junior basketball tournament with over 1100 teams playing more than 7000 matches over the weekend!). I took about 1700 shots over the weekend and as my initial AF settings seemed to be working well, I did not change them much over the weekend.

My settings and comments are:
Exposure program - I use TAv - control the shutter and aperture to minimise the ISO - there is never too much light shooting basketball!
Aperture - F2.8 mostly to keep ISO as low as possible (increased to F3.5 if light was better but to be honest, with this lens I do not notice any difference in IQ)
Shutter - the boys are 15/16 years old and move pretty fast so 1/320 is a minimum, 1/250 works but you can expect some motion blur on hands & the ball
AFC
Use the AF back button
16. 1st Frame=3, in-focus priority (I think it is better to get the focus right at the start of the sequence and if it focuses on the wrong subject then you have the chance to repress the AF button/shutter)
17. Action in AFC = 1, Focus priority
18. Hold status = 3, Medium. This works really well - a major improvement in stopping the camera re-focussing on the wrong subject. I had a number of instances where the referee passes between the player and camera, obliterating 25% of the frame but the player remains in focus!
Expanded area Sel 3, with the initial focus point in the centre. This seemed to be working and I did not really try other settings. Maybe Sel 2 is worth a try??
Continuous shooting - High
All taken with firmware1.01 - v1.02 has reportedly further improved the AFC.

My general technique is to:
Target the player's chest (in portrait and showing feet, head, hands and usually the ring)
Hit the AF button and hold, the camera acknowledges focus point in the viewfinder (and ping).
Follow/track the player keeping the focus area centred in the viewfinder and take the shots when you think they will be best.
Repress AF is focus point is lost.
Crop image later to recompose.

Some examples from the tournament are posted below. All taken with K3 & DA*50-135F2.8 and have been PP'd in LR5 - cropping, exposure adjust, sharpening and NR.
I have included the first two to show the cropability of the images - the crop is about 100%
The last image shows a player running towards the camera - the focus is maintained through the sequence and this was the best composed shot of the 6 taken

I originally wanted to post a new thread, back in November 2013 about what K3 users were using for their AF settings.
The thread was this one: https://www.pentaxforums.com/forums/3-site-suggestions-help/242972-suggestion...-settings.html

So, let's get this started !

Post your favorite K3 AF settings, in details, according to your type of photography, lens(es) used and tell us why you chose a specific setting.

Please ... no lengthy/useless discussion(s) not pertaining to the main idea.

Wonderful resource, I just got a new K3 and after I digest some of the suggestions on your posting I will offer some of my own that I feel are constructive. Again thanks again for starting the ball rolling!!

Yay! Just got my K3II today. Got most of my settings worked out, but how do I turn off the back screen status? Right now it runs that options screen when I turn the camera on, and I'd prefer it not do so. Can't figure it out in the manual.

Am I correct, there is no updated firmware for the K3II right now? I see some for the K3 but the II version is not listed in that.

Press the Info button a couple times, then use the four way controller left/right buttons to toggle through the options. The third box will turn off the status screen.

Just got my K-3 2 weeks ago... upgraded from the k-7 - what a big leap forward - especially the automatic focusing ability - so much better that I've been used to for the past several years. Still doing a lot of reading and learning about my new 'baby', but definitely impressed!

Quickly ...

Just got my own K3 and I use it with the DA*300/4 (plus perhaps the HD 1.4X TC).
For birders with the SAME setup:

What settings do you use, including settings for tracking/BIF/ those sort of things?
BTW, I think mine will need a slight AF fine adjustment.
Thanks!

I just upgraded to a k3 from a k50 and can't seem to get consistent results using center point focusing. That's all I ever used on my k50. So I will definitely try using some other AF settings next time I go out.
