K-x Bulb mode write-time slow?
@Amoringello - yup, you're right. It's the same on the K-x. Just tested it to find out. Settings: Manual mode, Shutter = Bulb, Aperture = f32, ISO200 selected, Manual-focus (MF) set on, focus set to infinity, 11pm(ish) darkness, IR-Remote-triggered shutter in 'one-push-to-open, one-p...

Exposure stacking is the usual answer. Search for Registax - it's free and lets you use multiple exposures of a single object. It has the additional feature/side effect of averaging out the noise over several exposures so you get decent inky blacks instead of a field of chroma noise. Is less than 30...

K-x Bulb mode write-time slow?
Is less than 30sec per exposure good for stacking of night time photos? I might be trying to get star rails in the next week or so, but am not going to sit through dark frame subtraction of fifteen minutes to two hours! I'd like to use the K7, but will likely have to fall back to the K10 unless st...

Bad form to follow-up one's own post, I know... but I hadn't realised we'd got to a second page until I posted my reply above! Whoops. Thanks are also due to flossie for the tip-off about the el-cheapo Remote Control. Ordered and (hopefully) on its way. Having said that, I'm still going to buy...

K-x Bulb mode write-time slow?
Sadly, with the K7 this cannot be fully turned off, probably the same with Kx (I believe K20 is the same way). As I understand, in ANY bulb photo over 30 seconds the frame subtraction is forced! In some photos over the specified maximum ISO and shutter speed, this also happen. I do believe this ac...

K-x Bulb mode write-time slow?
I'm intrigued... given that we're all here on a Pentax-supported 'official magazine' forum, can anyone tell me whether the PU magazine team have challenged Pentax about this inability to turn off the Noise Reduction issue? /nostalgia mode on/ I was Technical Editor on a couple of national comp...

...what do other marques with CMOS sensors do? If they all have NR permanently on then we have the inklings of an answer anyway. Good tack, John. Alas, my knowledge of what the other marques do with CMOS (or even which ones have CMOS rather than CCD) is nil, currently. I might try and find out, thou...

An update... I tried to find an email address for Pentax Japan, though their website seems to make a point of not publishing anything other than telephone & fax numbers or street addresses in Japan. I s'pose I could write them an old fashioned letter, but I'm not sure I know how to work a pen any...

*istDS to K200d
Morning, I've finally replaced my *istDS with a very nice K200d [1700 shots, described as 'mint' on ebay and it is!] Apart from the obvious SR, bigger screen, better iso etc, where will it excel over the *istDS, and which situations should I consider using the *istDS instead? For example, ...

*istDS to K200d
Thanks for all the suggestions and comments,. Re infra red..is that a case or using a filter or is there more to it? I have seen some 'converted' Pentax DSLRs on Ebay. Would the *istDS be a good camera to put a split focus screen on and use for MF, I have a selection of lenses that fit the b...

*istDS to K200d
Like Jon says it can be just a filter like any other lens filter but you can also convert your camera by a specialize shop, they will place a permanent IR filter infront of the sensor instead of the lens so that you can see something through the viewfinder :) Here is a non typical IR photo of min...

That sounds interesting, think I'll give it a go! Jon, PM coming your way. I also have an split old focus screen so might give that a go too. Andy

*istDS to K200d
I also have an split old focus screen so might give that a go too. That would most likely not work, different sizes in focusing screens you see. You need one specially made for your camera model I believe.

*istDS to K200d
I 'made' one for my mow deceased K100d by cutting a FF one down to size, and still have it. It was from a P30 and the same thickness as the one I took out [measured with a micrometer] but I never trusted the focus after fitting it, it always seemed a bit off. So if the K100d uses the same size [a...

k-x crash while using video
Has anyone else had this problem? The camera appeared to crash when the shutter button was pressed, the screen showed vertical lines and the on/off switch refused to work -- ie: I couldn't turn the camera off. Eventually took the batteries out and they were hot. (They were new in, duracell alkalines...

k-x crash while using video
What firmware does your K-x have in it, Rob? To check the version number, turn your camera on while holding down the MENU button. The version number will appear in the center of the LCD screen. The original v1.00 firmware has issues with battery metering and gives false readings. It may even con...

kx images soft?
After reading all the problems with blured images from the k7 and the kx. I decided to return the kx and get a used k20d instead with 6 months gaurantee. Guess what. I put the 77ltd on the k20d and nothing but soft images. Nothing in sharp focus. So it seems that my lens is faulty. Still under...
