There was a discussion about this a few years back, I posted some examples: https://www.pentaxuser.com/forum/topic/coastal-sunset-panorama-6484/p-0#comm_54822

Well I never! Just had to check my K-5 to make sure it's not on there and I just hadn't noticed it - can't see anything, anybody like to point out I'm wrong again?

Now, if they could do 3D-Tracking like Nikon, that would be lovely!

Mind you, just saw that sale was in 1998, don't know whether prices would have risen or fallen since then, but your offer of £500 might suggest it's gone up.

Might be worth giving Christie's a ring...

Just had a look at the manual, and amongst all the things that say AF-S locks the focus, AF-C tracks it, it does say that if it determines the subject is moving, it will track it, even if the focus is set to AF-S.

That's certainly not what I'd expect, but it would be a useful option, like AI-Focus on Canons. I've never had any of my cameras do this though, and would be surprised if the K30 did it, but maybe it does...

Dan

Well, it has always been my experience that if you set AF-S, that's single shot autofocus, and once it locks, it won't then track at all, because that's what AF-C does.

I've not used a K100D, so I can't comment on that specifically. Maybe I'll download the manual later.

On my *istD, K10D and K-5, the camera will not track a subject when using AF-S, that's why I mentioned it.

Dan

The K100D just had the option of AF or MF on the switch by the lens mount. The K30 has the options AF-S, AF-C and MF, so it's down to the user to decide on the best mode.

Well, I've just done mine. Charged the spare battery up (as the one that was in the camera was showing partially depleted the other day). Took some test shots before the update; a ruler next to my monitor, partly in shadow, and the dark brown cupboard in the dark hallway (was doing this without the card in the camera, so don't have these images, was just zooming in on the quick review image).

About half the shots taken then were out of focus - significant blurring in these cases.

I then updated the firmware. Just as it started phase 2 of this, I realised the freshly charged battery was still next to the keyboard...

All went well however, and then I took more test shots. I hadn't moved, the lighting hadn't changed (artificial light). All these shots were sharp (albeit looking like I need to update the AF adjustment slightly). Consistently focused. The ones of the cupboard were in a different league to those prior the update.

I was skeptical about AF improvement claims with this update - now I'm not.

Just hope it hasn't messed up the exposures.

Part time for me too, and most of my income is from tuition - workshops, private tuition etc.
