Cleaning CCD in *ist D?
Just to add to this thread... found the UK distributor of Eclipse, Pec*pads, and SensorSwabs: http://www.crown-digital.co.uk/ (more details from the US website: http://www.photosol.com/) Have ordered mine already and I'll let you know how I get on ;) (Have some real globs of dust on the *ist-...

Old Pentax SFXn SLR lenses on *istD ?
One point I forgot to mention, just in case you are not aware of it. Most digital SLRs use a sensor the size of an APS film frame, not a 35mm frame. This means that the camera appears to crop the picture on all sides - you just get the centre portion. The effect is similar to using a lens wit...

*istD Samples
I did a quick little setup here today to try the quality of the sensor at different ISO settings... from 200 - 3200 The quality of the 200 and 400 was obvious, but I wanted to see the 800 and 1600 in particular. The 800 is great! The 1600 is noisy and I would only use it for doing BW prints (I love...

Optio S4 shutter query
I have just purchased the S4 and have been going through the manual. The S4 has an electronic/mechanical shutter which can be adjusted to open between 1/2000 and 4 seconds. The electronic light sensor is comparable to actual film in that under and over exposure effects are possible. One function ...

*istd Focusing Screens & Mirror-Lock-up
I also wondered about this, as I find the AF guidelines really annoying. And as for the focus confirmation light, it's not a patch on the eye (my eye, at least), and I certainly wouldn't rely on it. Anyway, I've asked Speed Graphic, who do all sorts of different screens for most cameras, but they...

*ist D LCD
No – with the *istD the CCD is not exposed until the shutter is released. In a DSLR the mirror (and the shutter) covers the sensor whilst focusing etc, unlike the point and shoot digital cameras where the CCD is continuously looking at the image. You can view images in the memory but can not view...

What is going to be...?
I'm reading all kind of articles about digital photography and there is one thing that bothers me or better I'm afraid of. Where is digital tehnology heading to? In the direction of full frame sensors or different lens tehnology? I was thinking about purchasing an *ist D but I dont realy know. The...

What is going to be...?
That's a lot of questions, Saso! First of all, although there have been a few 'teething troubles', and misunderstandings, I find the *ist-D an amazing camera. The quality is awesome, especially when you shoot in RAW mode, and use Photoshop CS or Capture One. Usability is wonderful - I can pick...

Magnification/Focal Length
A good film lens should normally be a good digital lens, but there is one practical consideration to bear in mind. A lens with good centre resolution and poor edge resolution will work better on a digital camera (with an APS-sized sensor) because the edges will have been cropped off. Generally...

*istD dead pixels?
Does anyone know what the pentax photo browser software does when it converts RAW to TIFF? I shoot in RAW, and have noticed what appears to be a dead pixel in the middle of the sensor. (very bright blue speck) Consistent across many shots. I think this means that I need to get the body replaced (o...

*istD dead pixels?
Curiouser and curiouser. Thanks for the info on the sensor. The problem seems to have "gone away" - I had some images with a consistent bright blue pixel in a particular place which I could get back to by viewing an image, magnifying to x6, and moving right 8 times. After finding it and conta...

Spotty istD images
Hi I finally decided to go for the *istD just last week. Started shooting with it on Saturday and since have taken about 100 or so images. The latest ones show some greyish/black spots - one in particular. The marks appear regardless of lens changes so I presume the marks must be either imperfectio...

This sounds like a classic dirty sensor. There are various threads and external information on various sites about how to sort this. They vary from blasting the sensor with air, using a sensor cleaning kit with isopropyl alcohol plus wipe, to an indignant "I wouldn't touch the sensor at all" f...

Spotty istD images
As the 'Phone says, there are various options. It is odd, though that yours developed this problem so quickly. I would take it back to where you got it and ask them to fix it, because it sounds as though the camera came with a dirty sensor. Failing that, the first thing to try is to blast some ...

All sensors will inevitably come with a few 'dead' pixels, but these shouldn't be obvious. You might pick them up if you zoom in in Photoshop. I would advise against using compressed air cans to blow the sensor. They blow cold air that can cause water vapour to condense on the sensor!! Stick to ...

IST D'S'
Every lens back to K mount will works on the *ist DS. You are going to have a 1.5x cropping factor because of the less than full frame sensor - making your 28mm into a virtual 42mm, 50mm into virtual 75mm, ect. mm.... 300mm into 450mm... but I digress. (The *ist D's crop factor was 1.5x and I'...

Remote for *ist D
Hi, I use the Pentax remote F with my *istD and can confirm that the shutter will stay open for as long as the button is pressed. The only minor problem is that as it's infra red and the sensor is on the front of the camera that means you have to be in front of it too. I also use a wired remote ...

More sensor cleaning - beware the blower!
Hi Guys just a note to tell you of the woes I've had this week with my *iSTD and how I solved the problem. One of the first things I bought following the purchase of my new camera was a new blower which i bought from Jessops - a model called the 'Hurricane' - it looked suitably big and powerful. I ...

More sensor cleaning - beware the blower!
...not so sure about putting sticky gel on the CCD... Because the CCD is electrically charged, some gunk can get really stuck. I'm not sure that the gel will always remove it. FYI, I've followed the instructions available on the web regarding the use of Eclipse fluid and PecPads, both of which a...
