Neutral Density Filter Colour Cast
Went out today to try out my new ND filters on my K100d at my local weir. I was using an 8, 4 and 2 stacked, white balance set to daylight, 0.5 second exposure gave me this... Took the filters off and changed from shutter priority to Auto and got this... Put the ND filters back on a...

Neutral Density Filter Colour Cast
Filters are cheap ones from ebay link Obviously the old adage of 'buy cheap buy twice' must apply to ND filters. Lens is a Carl Zeiss Jena Jenazoom super 28-70mm f/3.5-4.5. Exif data from first shot. A lot there, not sure which parts are the important ones :? Camera Pentax K100D ...

K20 Auto Focus appears to have stopped working
Hi All I don't know if you can help but my auto focus has appeared to stop working on my K20. I was doing some work for someone Friday evening when low a behold the camera wouldn't focus. I managed to do the work in manual so it didn't cause that big a problem but was just a bit frustrating. ...

K20 Auto Focus appears to have stopped working
Do you still get the green "AF-S" at the top of the screen when you switch the camera on?

K20 Auto Focus appears to have stopped working
No - never had any trouble with mine. I was just trying to work out where the problem is. If the switch was duff, you probably wouldn't get the AF-S. As it is, the fault is probably with the autofocus system itself. The only thing I can suggest is cleaning the contacts on the lens mount on your c...

K20 Auto Focus appears to have stopped working
For what it's worth, I had a similar with my K20D and 200mm DA* SDM lens. Turned out to be a compatibility issue between camera/len and Metz 36 AF4 flash gun. While the flash is listed as full Pentax compatible, it upset the camera AF system when using an SDM lens. Removing the battery from the c...

K20 Auto Focus appears to have stopped working
I had an af motor inside an mz5 break from my (ex) manually turning the af ring while the body was set to AF. it was a warrenty repair at that time. The af motor is inside the camera body... possible someone was trying to manual focus on your camera with the AF on?

K20 Auto Focus appears to have stopped working
Hi Lad Thanks for the replies. In reality I have probable taken around a 1000 shots on each of the lenses so I don't think it's a compatibility issues as I think it would have shown up earlier. The motors are running fine on both lens, plus they work (my Pentax lens)fine on my D-ist. I tried...

K20 Auto Focus appears to have stopped working
Hi All Just to add to the above, I am in the process of bundling up my K20 to go back to Pentax and thought I would have one more look at her. She still won't auto focus in Auto and Spot focus, but there are about five regions she will focus in Select, bizarre. The other good news is I am a m...

K20 Auto Focus appears to have stopped working
Hi All Just to let you all know my autofocus problem was due to fluff in my mirror box, (see reply from Johnsons Photopia). Even though my Camera is out of warranty they have cleaned it free of charge. Can't really ask for more than that:D Thanks Johnsons and all the best Andrzej "Dea...

K-X Bulb problem
Nope sorry - the dark frame subtraction is not an issue. This is entirely different. It only does it perhaps once out of every ten - sometimes more and sometimes less - long exposures. The shutter does not seem to close correctly or maybe hasn't opened correctly in the first placce, hence the differ...

16-45mm not behaving itself?
The exif page is here: Unsurprisingly it's f8... my default aperture setting! I take your point about DOF effects, as the focus is on the shore, not the hill... but the blurring seemed strange, not like the normal OOF effect. And it seems worse at the top on the left hand side than on the mo...

It sounds like you are doing something unsuitable for the situation, but hard to know what without being there. Forgetting the flash, which kills atmosphere anyway, I would set a high ISO and a fairly wide aperture and then prefocus on a spot, holding the exposure and focus point with a half pres...

Tamron 90mm focus issue
I've had a Tamron 90mm for a fair while now (I'm sure its out of warranty anyway), on my K20D. It lives on the camera in my camera bag. Took it out today and it just would not focus, it wasn't seeking, it would just make a tiny motor noise and then the hexagonal I-can't-focus-on-anything icon fla...
