Infra Red on istD?

Don Schoolmaster, The other fact to bear in mind is that the Dimage 7 uses phase focussing (I think) - by reading information directly off the CCD. Hence, any sensitivity in the IR range will allow it to focus. The *istD, on the other hand, has seperate focussing, as in all the film versions. ...

Pentax *istD underexposed with AF-360FGZ

Hi All! Ok, now I am more confused. I decided to go back and try a genuine Pentax-FA 28-70mm F4 and do some more comparisons and tests. Here's what I did: take the *istD with lense on a tripod looking at an evenly lit magnolia wall. Set focus to manual and infinity. Try different ISO settings ...

Pentax *istD underexposed with AF-360FGZ

I don't yet have a *ist D, so forgive my lack of detailed knowledge. Which device is doing the metering, the camera or the flash? If the former, what metering mode is set? If it's spot, it could well give entirely inappropriate results. If the flash is doing the metering, then what is the ...

Pentax *istD underexposed with AF-360FGZ

Hello Guest, It is the camera doing the metering - in P-TTL flash mode. That is, a preflash is fired from which the camera does the metering, adjusts the exposure appropriately then fires the main flash. Regarding the metering, it is true that spot metering could affect things, and indeed it doe...

*istD underexposure?

Jose B, Yes, underexposing is annoying (and I agree with the focus assist - grrr. However, when you use the AF360 that has a proper AF assist!). However, there are a few differences between the *istD (and all DSLRs) and the Minoltas you specify (and indeed all consumer digicams): * The *istD ha...

learning ist D

Hi Ava You have a camera very capable of producing superb images from its 6.1MP sensor, but these files will be large. I guess they might produce a photographic quality print of around 15 by 12 inches at 300ppi. You could argue that there's no point having such a high resolution and then reducing...

*istD RAW support

Shotgun, I have managed to get Vuescan to give acceptable results, but quite "flat" and dull. I must be doing something wrong somewhere. However, I have been looking at dcRAW (the commandline tool) more. dcRAW is used by VueScan, Bibble, Breeze, Adobe Photoshop etc etc. I produced a 48bit PSD ...

Older non Pentax flashes on *istD

Hi I have an older flash for my praktica camera which I wondering if it'll work on my *istD. It's an Starblitz 2500 BTZ. It has only the center connector in the hotshoe and work as an auto-flash (light sensor on flash). I'm worried if the flashvoltage could damage the *istD. I've read on the net ...

Dust?

I suspect so, it's similar to what I came across (although I didn't have that many speckles). However, after blowing the sensor carefully they were gone. (And were later on replaced by new ones...). Sometimes they show up even darker, sometimes they are hard to see... Cheers, Prieni

Cleaning CCD in *ist D?

I have tried blowing the dust off the CCD, but it still needs more cleaning to remove small dark circular areas that appear in photos of clear skies. What is the view on cleaning fluids and swabs such as those at ?

Cleaning CCD in *ist D?

Malcolm, From whay I've seen, the general opinion is to never touch the CCD with anything :( For the Fuji S2, I've seen people recommend only specialist cleaning if there's real gunk on the CCD. I bought one of those huge air puffers from 7dayshop which seems to get rid of pretty much anything...

Cleaning CCD in *ist D?

Thanks. I have ordered one. Out of interest, a blower might only circulate the dust within the camera body. Would any harm be done by using a Dyson vacuum hose to SUCK the dust away rather than BLOW it around providing no physical contact is made between the hose and the camera body?

Cleaning CCD in *ist D?

I wouldn't suggest that :shock: Vacuum cleaners can generate a huge amount of static electricity, because of the moving air. Such static could pop the electronics in the *istD. If you've ever seen the price of a static-free vacuum cleaner, you'll understand! With the large blower, I find ...

Cleaning CCD in *ist D?

Here's another CCD cleaning website: http://www.bythom.com/cleaning.htm I hope I never have to do this as it sounds scary. The protective layer on the CCD is said to have a hardness of 5 on the Moh's scale. This comparitive scale is used to classify minerals (talc is 0 and diamond is 10). As a...

Cleaning CCD in *ist D?

First, a warning: these are my results, please don't hunt me down and kill me if something horrible happens to your ist D after this! I have succesfully cleaned my ist D's CCD with PecPads (99.999% lint-free) and Eclipse solution (basically ether) as I watched a professional D100 user do. I was a...
