K3 focus issues most confusing
That's much better Dave! BTW, got my DA*300 last night, it was dark when I got home from work so tried a few shots today. First impressions are that focus is absolutely nailed on with the K-3, no adjustment required and boy is this lens sharp wide open! Can't wait to get some birds and butterflie...

K3 focus issues most confusing
Looking forwards to seeing them David. That's the crux - F4 is sharp, makes a lot of difference in wildlife.

Sigma 105 Not Registering Aperture
Just an update.... Finally got my hands on the correct screwdriver, just took out the screws in the mount, gave the mount a jiggle, re=seated it and tightened the screws back up and it worked a treat!!!

Typical Sigma issue - there are a couple of threads somewhere about this. I have the same prob...

Sigma 105 Not Registering Aperture
I'm just glad it's back, I've been contemplating replacing it with another. My world makes a little more sense today :) My summer is back on ;)

50-135 SDM not working
I think you could try turning the focus mechanism with a small screwdriver via the screwdrive slot, this seems to have worked for some people. I wonder what causes the SDM motors to fail like this? Maybe someone can give us a technical reason. Regards David

50-135 SDM not working
If you do need a repair pay for pentax plus membership to the forum and this will give you 20% of repairs at Pentax repairers JP solutions, the repair will replace the SDM with the latest motor which should remove the failure possibility substantially. It also makes it a bloody sight faster to focus...

50-135 SDM not working
Mi 16-50 also needed to be woke up before use by just refocusing it for a few times manually while attached to the camera. Try it you never know. It still does :mrgreen: With the K5ii and the K3 and quick trip in to LV and using the back AF buttom seems to wake it up, might be worth a try with t...

50-135 SDM not working
I know it's an old thread, but worth re-visiting I think. My 50-135 does need to be 'woken up' sometimes but I've also noticed a different issue which only happens when the lens is on my K-5iis, not on my K-3. Sometimes the shutter won't fire, it seems to be trying to go but doesn't make it. It's...

While lens correction doesn't work AF calibration does. Have you checked it's focus?

K5 randomly releasing mirror upon half-way press of the shutter
Had a similar sounding problem with my IIs the day before it went back for a different repair. It came back after they had reset the shutter, but never got to try it out due to the other repair not getting done, buts that's another story!

K5 randomly releasing mirror upon half-way press of the shutter
Hi Ohawa, I had this problem with my K5. I bought it in March 2011 and there was no problem till August 2011 while I was recording travel well away from home - as you know it is very annoying. It was under warranty and I sent it back to the dealer. The camera was replaced, so I suggest that you d...

K5 randomly releasing mirror upon half-way press of the shutter
A funny thing found during this weekend: the strange behaviour with shutter releasing several times by itself before finally reacting correctly, is NOT present when in manual focus! When in AF it does it (randomly). Any clues? Anyway, contacting Pentax (and hoping for very nice response) is I thin...

Pentax K5II Lock Up
Hi all, My K5II is approximately 9 months old and still under warranty having been purchased through SRS but I am trying to find out if mine is an isolated issue. About ten days ago when using my camera in manual mode with an A50 lens, the camera suddenly locked up, with the red focus square p...

Pentax K5II Lock Up
My IIs did it 3 times in the 1st couple of weeks, I said Id send it back if it did it again, it never did. My advice is to just use it, let it settle down so to speak.

Anyone know if new converter works with 55-300 Ed?
Apparently the Pentax converter may not work with this lens the auto-phase focus may not work . It would only work manually so is it worth getting? Thanks.:)

FLUCARD_for_PENTAX connection issues
Not done a cold boot(!?) - sounds scary! - yup and tried it with my router off, don't think there's a conflict with the IP address - I sent the flucard back to SRS but they think it's not faulty and the camera will connect through it to my laptop so...when I get it back I'll try again. Thanks to all...
