Why do Pentax lag with autofocus?
Why is it some people on forums always want a fight! I give up. I'll just wait to see how Ricoh get on in the future as they seem very sensible and probably know that AF is the major concern of otherwise very happy Pentax owners. Dave[quote:3496ace15f="awaldram"] Nope I think all manufacturers...

Why do Pentax lag with autofocus?
Back to dcweather's original posts, I'm surprised that no-one's picked up on him saying he doesn't use AF-C. If not, and he's using AF-S, once the camera does lock on, it won't then try to follow focus, and will happily fire away with the subject getting further out of focus all the time. My pre...

Why do Pentax lag with autofocus?
As far as I know, one of the major factors here is that Canon and Nikon both use predictive focus, and have done for years. The camera measures the speed that the subject's distance is changing, and then predicts where it will be once the mirror has flipped up (which also cuts off any input to the ...

Why do Pentax lag with autofocus?
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-Focu...

..... 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... K-30 has an af.a mode just like my old pentax Z20 fom the film days, it is just like...

K-30 has an af.a mode just like my old pentax Z20 fom the film days, it is just like the AI-focus on Canons and picks af.s or af.c dependent on subject motion. 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 po...

Why do Pentax lag with autofocus?
The elderly Nikon D300 has possibly the best sports autofocus of any semi pro camera ever made so if your K5 isn't quite as good I wouldn't beat yourself up. It's also big and heavy and only 12MP with no video or weather sealing etc. Horses for courses. Anyway sometimes it's easier to manual foc...

Why do Pentax lag with autofocus?
You have a choice with Pentax DSLRs of setting the AF to focus priority or release priority, so that may make a difference. Pentax AF is actually pretty fast as far as I have found, and reputed to be more accurate than other marques, but very fast subjects will be missed more often than still one...

Why do Pentax lag with autofocus?
No, doesn't do it automatically in AF-S, that would be a PITA when it got it wrong. Perhaps Pentax's thinking is that someone with a K-5 would want to be in control of what mode it uses, and not leave it down to the camera to pick. I tend to advise Canon users to leave theirs in AF-Focus (AF-A),...

24mp APS-C?
Apologies if I've read you wrong john but I think you're missing the point here I'm not sure if there's any contradiction, but the point I was making was that for a single type of consumer there's a law of diminishing returns and a saturation point. Beyond that, new products are needed that will mov...

24mp APS-C?
When we refer to 'IQ improvements', a lot of the emphasis, both on what people desire and what might be delivered, is on high ISO / low light performance (ie reduced noise at ever higher iso settings), which is obviously important to people. Absolutely - that is the main reason why I upgraded from a...

I hope they've allowed a colour change for Focus Peaking. White is often next to useless.

New Pentax Firmware updates for 6 cameras
Was that as a result of the Update Steve. if ao did they require any adjustment, with different values, before the update? As per previous post, all the lenses needed a tweak on the plus side (an extra 3-5 points) The FA35 and DA55-300 were previously at 0. The others were already on the plus side...

New Pentax Firmware updates for 6 cameras
I have just downloaded and installed the V1.14 firmware on my K-5 (absolutely painless process) and I would tend to support the views that Steve Coe published on this thread. My K-5 (mk1) is now locking accurately and quickly onto subjects in very dim light indeed in my living room with the 55-300...
