Help auto focusing in low light
Lenses with smaller apertures are going to struggle even more. If your lens will only open to f5.6 it will have a lot less light to work with than say a f2.8 or f1.4. Someone sells a cheap little attachment with a row of LEDs that help illuminate for focusing. But I think they are on all the ...

Help auto focusing in low light
We all struggle to focus in low light, not just cameras. It's because we use light to focus, and when there isn't any, we have a hard time doing it. G

Help auto focusing in low light
Hi Tim, Autofocus works by looking for contrast changes in specific strips of pixels (AFAIK), so in low light you are not going to get much contrast in those strips, therefore autofocus wont't work in low light. For reference Pete.. http://en.wikipedia.org/wiki/Autofocus If you have a flas...

Help auto focusing in low light
Pete, You can help the AF along a bit... Switch the focus selector on the back to "Centre Only" - point the very middle of the viewfinder on something you can see has contrast and focus with that. Personally, I find it much easier to use the custom function that disables focus-on-ha...

Help organising my images
I too have Elements, and use that to a certain extent. But I also have folders and sub folders in My Pictures (I assume it's called that in English - I have Dutch XP) so I can find things quickly - Macro, Landscapes, Dogs, Family, Holidays etc for the main folders then sub folders and sub sub folder...

Using old Pentax M lens on the K10D Help
Hi I have an old pentax M lens and I set the ring to A which then works the aperture on the K10D in auto etc... I have to focus the camera lens manuel but I am finding it difficult as the little red focus point in the viewfinder and bleeping sound is very sensative whilst turning the focus ring....

Using old Pentax M lens on the K10D Help
Pete, A few points: * The red indicator is only an indicator. You should rely on the Green "in focus" indicator at the bottom of the view finder ;) * If you switch the focus switch to "M" (on the left side of the camera at the front) then the camera will let you take the s...

Using old Pentax M lens on the K10D Help
Hi I have an old pentax M lens and I set the ring to A which then works the aperture on the K10D in auto etc... I think Pete just meant MF for manual focus as opposed to M for M series.

Problem with my K10D not sure if its a fault ????
If you were wearing a wide-brimmed hat while taking the pictures, then that could account for the problem. But if you weren't, it wouldn't. G There are some jokes that shouldn't be explained. Joke? This was an entirely serious suggestion. As Pete is allegedly in Spain (last time I heard)...

Problem with K10D and Bigma combination?
Hi everyone, I traded up my Pentax isDS and Sigma 170-500 to a K10D and Sigma 50-500 (Bigma) Combination a few months ago. Looks like I have a problem, as the Autofocus has now gone for a second time on the Bigma and it is back with Sigma for repair. Something nasty is happening inside the le...

Problem with K10D and Bigma combination?
Thanks for your comments I should be hearing from Sigma early next week, and will report back the findings! The results I had with the Bigma (before the failures) were excellent, Luckily I still have my Sigma 170-500, as a reserve, which is working fine on the K10D!,

Problem with K10D and Bigma combination?
I have received my lens back from Sigma, a week turnaround as an urgent repair. The technician has replaced and adjusted the gears, which he assures is the best solution to the problems that I have been experiencing but if the fault should re-occur Sigma will replace the unit. Well the Airshow ...

K10D long (ish) exposures
here is my suggestion for astro shots AF is irrelevant since if you ever come across an object in the night sky for which infinity is not the correct setting, the sharpness of your photos will be the least of your worries. The phrase "dear God, it's going to hit us!" springs to mind. ...

Sunset Final Shot
This sort of artifact on edges usually indicated too much sharpening... But when using HDR it often indicates too aggressive tone mapping ;) The main art to HDR tone mapping is moderation. When you start using it you want to include everything in the image with complete shadow and brightest highlig...

Battery depleted message . . . on my K10D + grip & battery
I had exactly the same problem a few days ago. I had to remove the battery from the grip, switch it back on, go into the menu and tell it to use body first and then I could put the dud back in the grip. Very irritating as I fully expected it to automatically switch when the grip battery became...

What's Exposure Metering Time?
Spent some time wondering that myself. If you hit the AE-L button, this locks the exposure metering and a little "*" appears in the viewfinder. The time for which this stays locked has to do with a multiple of the metering time. The manual is clear as mud in this regard, but I believ...

Pentax K100D vs K110D
Funny how a dumb question can get so heated. I LOVE this forum! I've always progressed slowly - from screw mount Spotmatics, to K mount Super Program (Don) to Auto Focus (George) into 6.1mp Optio digital. Fortunately there are plenty of kids and relatives to pass the older technology along to....
