what tripod?
Right, time to add to the confusion! Had delivered yesterday a 2nd hand Manfrotto 058, and boy o boy, what a difference. We both had a small play with them in the living room, and the difference is amazing. As I mentioned above, the 055 tripod felt like it was the weakest link now we have the ...

what tripod?
Does anyone have any experience of the Slik AF 2100 trigger style ballhead as shown on the SRS website :?: In particular does anyone know if the base fitting is 1/4" :?: Sorry, I hadn't really been following this thread, just noticed this. I've been using one of these for many years (at le...

K100D and Batteries
The long shelf life NiMH's are more commonly sold as Uniross Hybrios in the UK. I have had mixed results with mine, overall I prefer the 7DayShop 2500s which I have found to have a suprisingly good shelf life, although it is possible that my charger just doesn't like Hybrios very much. My Dad ten...

Pentax Adapter
M42 lens to K body is easy and common, there are always loads of them on ebay, you just have to watch out for a few of the cheap knock off ones which loose infinity focus. K lens to M42 body can't be done without either using an optical adaptor which functions as a short teleconverter, or loosing...

Pentax Adapter
Thanks for the reply Mongoose, By loosing infinity focus, is this because of the thickness of the adapter,if not why does this happen

Thanks for the reply Mongoose, By loosing infinity focus, is this because of the thickness of the adapter,if not why does this happen Yes, Some of the cheaper adapters have a flange on them and this causes the lens to sit proud of the mount. A better quality adapter will sit flush with the mount an...

Model revision on K10D
he, he, looked at some older photos, I had revision "1.1?" manufactured back in 2006. Had to have a major repair done over Christmas where they replaced the motherboard, etc... I now have revision 8.1 with manufacture date 2007-12-11. Although now the Pentax Model is not set. Odd. ...

Model revision on K10D
I had to send my K10D for repair because of a finicky AE-L switch. It left with model revision 1.2 and came back with model revision 8.2. As soon as I can find the time, I'll try to duplicate some photos I took during night time to see if the noise is lower. It might take a short while since I ha...

Model revision on K10D
Now that some of you got acquinted to PhotoME, I heard through the grapevines that if you have model revision 2.2 or higher, there is less digital noise. Anybody got 2 different bodies with the aforementioned revision number able to conduct some test to see if it's true. As far as I can figure out...

Model revision on K10D
As far as I can figure out, any revision number that start with an 8.x seems to be a camera that was sent for repair. I couldn't find a new camera with model revision 8.x, only cameras that came back from service. My K10D came from the forum that you read this from (I think) and in the box was a ...

Setting SR on manual focus A zoom lens.
Hi all. I was wondering what setting I should enter in the SR menu, when using a manual Focus Pentax A zoom. For instance a 70-210. Four options? The lowest end=70mm. The medium end=135mm The longest end=210mm Or adjust every time I change focal lenght?( I sure hope not ) What is recommended? ...

Setting SR on manual focus A zoom lens.
Well in theory you would change it I sippose, but in practice I'd set the middle ground as an average. If you knew you were going to use the lens pretty much at one setting for a session then that is where it could be set.

Setting SR on manual focus A zoom lens.
Thanks John, I was thinking along the same line here, but wasn't sure. Most of the time it won't be a problem, because of the tripod use. Good light, Martin.

Setting SR on manual focus A zoom lens.
This is how I think about it, I'm sure I will get shot down in flames if I'm wrong... If we use a wide angle lens with say a 100 degree field of view then move the camera 1 degree during the exposure then the sensor will need to move 1/100 of its size to compensate. If we use a telephoto lens wi...

What's up with my onboard flash?
Timing and flash power seem to have a lot to do with it. Sometimes pure luck and slight change of position will change something to allow the flash to work. You might try putting the 360/540 into slave mode 2. Rather than using wireless, it turns into a dumb sync flash. (no wireless PTTL commu...

What's up with my onboard flash?
Thats good to hear. I'm looking forward to using them. Its likely going to be a few weeks until I get my strobes back and give the triggers a good workout. I'm using the universal receiver, so at least I have options while my strobes are out for repair. Now I just have to figure out how to ho...

K10D Auto Focus
I have found the auto focus a bit of a nuisance this past week. When the subject a stone building some distance away, or a water scene for example. I have tried focusing on some more prominent feature but the camera seems to refuse to focus leaving the green light flashing. I have tried changing the...

K10D Auto Focus
Very obvious maybe......, but could it be that you have AF-C on instead of AF-S ? Martin.

K10D Auto Focus
Cameras focus by comparing areas of different contrast. So if you point the camera at a plain coloured wall, for example, it will have nothing to focus on. Sometimes you will need to aim at something a similar distance away which provides the high contrast that the camera needs. Them keep the s...
