K3 continuous focus.
It tracks for a while then just stops focusing till you release button and press again. I don't think that is right? Every Pentax body I have had did that ... including the K-5II I have now. I thought it was a lot better on the K-3.

K3 continuous focus.
Well I thought that might have been the case with my previous bodies but not really critically looked at it before so maybe that's just going to be the way it is!

k7 noisy in live view
An M lens will only operate at full aperture unless "use of aperture ring" is set to "permitted". Then you need to manually stop down the lens. All auto modes will work in Av regardless of settings, or you can use manual exposure. Have you also set the camera to manual focusing? Otherwise, perhap...

Optio WG-3 GPS with 64GB Kingston SD-XC card
Thank you all for your responses. Yes, I have tried formatting the card. It comes pre-formatted with extFAT. The camera recognizes it fine. After a few shots then it will give the "memory card error" and would shuts down. I have tried formatting it to NTFS, which of course is not supported ...

Something to be said for "breaking in" boots before a long trek. The same can be said for hi tech too. Take everything back to the shop and get them to look it over.....

PEF and Ubuntu
Either down to running the firmware update or finger trouble (most likely), I have ended up with a load of PEF RAW files. Darktable will not import/edit them but I can get them opened in GIMP, what will I be best saving them to? just after the best option for retaining the detail that RAW has cap...

PEF and Ubuntu
Well, I've been using DigiKam and Darktable for some time and have had no problems in either program with PEF files from my K-x and now K-5IIs. DigiKam will edit them, though I prefer Darktable. (Using Ubuntu 12.04.) Footnote: Darktable is pretty powerful, but I've found it a steep learning curve...

Finally
Well, my lens came back from Asahi Photo and all seems to be well. The delivery was actually a little unexpected, as they had not contacted me to let me know it was coming. Cost £120 for a replacement SDM motor and general service. The repair took a little longer (by about 2 weeks) than they had ...

K3 Focusing. Fault or too high expectations.
I have now had the K3 long enough to think that the AF seems more hit or miss than my previous Pentax DSLR's in certain conditions up to and including the K30. WHen it is right it is stupendous. But it often seems to front or back focus as well as get it spot on. In fact it seems to be in about eq...

K3 Focusing. Fault or too high expectations.
Wow thats some narrow depth of field your working with! I don't shoot birds but I reckon you're expectations may be a little high at 300mm (what's that in old money, 400?) Strange that you should get front and back focus though. Certainly would seem to eliminate the lens. Did you allow for win...

K3 Focusing. Fault or too high expectations.
I had a similar problem with my DA*300 (from new). I was very disappointed with it and came in for a certain amount of stick on the forum for suggesting my 55-300 produced better results (Frogfish even choking on his breakfast!) The lens was back-focusing badly but, more importantly, it was jumping...

K3 Focusing. Fault or too high expectations.
Good idea Gareth. NeilP is a friend on here and lives nearby and he has one and now a K3. Will have to get together with him. ... and Roger, yes maybe it should be sent back for a check over. It is well used and coming up to two years old. Sounds like a very similar fault to mine, except when it i...

K3 Focusing. Fault or too high expectations.
Dave, forgot to state that image 1 is superb. when the DA* hits the mark focus wise it looks like a very nice lens. I think i need to start saving my pennies and lot of them.

It certainly is a cracking lens Gareth - check out the ones that are in focus in my gallery!

K3 Focusing. Fault or too high expectations.
Hi Dave I haven't noticed any focus issues with my K-3 yet, although I've yet to test it on a wildlife shoot. My old K-5 Mk1 used to behave as you describe, although funnily enough it was with the 17-70, not with my telephoto lenses and it was unerringly accurate on my Siggy 150-500! That fir...

K3 Focusing. Fault or too high expectations.
Not sure why this would affect focus? It is fine DOF but why would it confirm focus on something clearly out of focus? It demonstrates it is perfectly capable a lot of the time. I think people like David and Alan Wennington are getting higher success rate under similar conditions.
