ist D Problem
Recently I picked up a used ist D, usually I use my card reader to transfer pics but recently when I connected it with the USB cable I discovered a problem. There seems to be connection problem. Unless I hold the cable in it won't connect. I don't know if the faults in the cable or in the camera. Otherwise I really love the camera but I can how this could be a problem.

Cables are generally more likely to be a problem than anything else. That said, I've almost never connected any of my cameras to a computer, I always use a card reader.

Evan, If you have a USB 2 connection on your computer and a USB 2 card reader, there is no reason to use the cable from the camera--unless you like s-l-o-o-o-w transfers (45 min to 1 h for a 2 gig card full of pix) and running the camera's battery down.

Re: ist D Problem
I don't know what kind of batteries you're using. I'd use the lithium AA's or the CR-V3's. To be safe, go buy new ones, don't use any from the same pack you have at home, if that's the case. The manual recommends using alkalines only in emergencies when nothing else is available, though I have done so often. However, as I recall, when I was experiencing the problems, it was with alkalines. Tom C.

eek! *Ist D problem...
Hi guys and gals, Just home from a wedding today in Byron Bay. Got some great stuff on the beach - great light and a beautiful sunset, but, EEK! midway through the day, my new *ist D (I have two now), started doing some strange things. Just on a whim, I turned on the preview screen to have a quick flick through what I'd been shooting, only to find a whole lot of black screens with nothing but red and blue lines running horizontally through them! They all had appropriate file numbers but no image! I lost about 20 shots, which luckily due to circumstances were able to be re-shot. Anyways, it progressively got worse throughout the day, sometimes with 6 or 7 shots in a row doing it. I changed the batteries, and the lenses, thinking it may be either of these, but it still did it. I then found that if I shot only single frames, and let the camera sit for a few seconds between frames, it seemed to not do it. This completely sucks though, as my shooting style at weddings is candid, and quick, often shooting four or five frames at a time in quick succession. Any ideas what it could be, or am I going to have to send it in for warranty? rgh, I have a really busy period coming up - I can't be without both bodies!!

Re: eek! *Ist D problem...
Try the higher voltage lithium batteries like the ones that came with the camera. Are you running it with a micro-drive CF card, or solid state? That can also drain the batteries faster. Using the flash can do the same thing. rg Tan and Steve wrote: Hi guys and gals, Just home from a wedding today in Byron Bay.

Re: *ist D problem at ISO 1600?
If you were trying to shoot the eagles against open sky, your shots would be considerably underexposed if you simply pushed the green button and relied on the center weighted meter reading. You would have to add one to two stops exposure to compensate for a background that is largely white sky. Combine that with extreme ISO and an iffy lens combination, and it's a recipe for disaster. The green power button, however, should have exposed somewhat accurately. I'll try something with my camera when i have time.

Larry Cook [EMAIL PROTECTED] wrote: Gianfranco, Hi Larry, First, thanks to all who replied. While I as well have had problems with the battery indicator being reliable on the *istD, that may not be the problem. Never thought that could be part of or affect the problem... In fact, the striping or banding happens even when the batteries are full. I have seen the striping effect at ISO 1600 and 3200 with good batteries in the camera. There have been several threads in the Pentax SLR forum in dpreview about this and one belief is that the striping may be due to the camera trying to write to the compact flash while also reading image data from the sensor into the buffer. I do not know if that is true but the only time I have seen the striping is while shooting soccer games when I may shoot bursts of pictures. In casual shooting (i.e. single frame shooting) I have yet to see the striping. I don't know of anyone actually running an experiement to prove or disprove this theory but from the anectdotal evidence it is at least plausible. Another thought is that it occurs with some types of microdrives. Having never used one, I can't say. That's what I too had thought, shooting several single pictures close enough to be taken while the camera is writing on the card (and, apparently, not in continuous mode). At least, it's the only thing I can think of that may have an interference of some sort. I do not own microdrives, and the problem do happen using cards of different size and brands.

Re: Battery Indicator (was:*ist D problem at ISO 1600?)
[EMAIL PROTECTED] wrote: Mine does this on occasion -- depleted indicator that shows full again when the camera's turned off and back on. That's because the batteries can recover from short periods of high discharge after a short period of rest. Here's the lowdown: You're never going to get a really accurate battery indicator ever*. Reading the output voltage of the batteries will always be only a crude approximation of the amount of useful life remaining because the discharge rates are curves that get steep very quickly and they fail to predict the future discharge rate to a significant extent. Having the option of several different *kinds* of batteries makes this kind of battery life prediction even more of a fool's errand (albeit a necessary fool's errand, because we obviously need *some* kind of battery indicator). This is the reason the battery life indicator is only two segments: A display with more steps is technically possible, but wouldn't provide any more real information. Basically, we just have to deal with three indications: 1) Batteries have a good, solid charge 2) You need to change batteries very soon 3) The batteries are dead; you should have changed them when you reached stage two. * One way to get more accurate battery life display is with dedicated batteries with built-in chips that measure not only output voltage but also things like current draw, temperature, time of use, etc. Laptop computer batteries typically have this kind of system, as do some DSLR's with dedicated, proprietary batteries, I suspect. But then you give up the universality of AA and CRV3 batteries. Personally, I unhesitatingly prefer the latter. I always carry a spare set of freshly charges NiMH AA's with me when I'm shooting digital. My camera bag also has a set of new CRV3 lithium batteries stashed inside, just for extra backup.

John, I follow about the same practice as you. Along with that, I charge and put in a fresh set before each session that I would be shooting.

Everything worked fine on it... except the battery indicator would flip out more often than not. It would show depletion... but then if you turned the camera off and on, or better yet just let it sit for a while, and it would be totally full again. The joke was that the camera was self-charging. But in all seriousness, we were told that this was the last kink in the system that Pentax had to work out... but perhaps they didn't quite get it right until a few production lines rolled. shrug jpc That's about my attitude to it, too. I think the battery indicator just jpc samples the voltage occasionally, rather than being a continuous meter. jpc If the camera was busy (focussing, writing to the CF card, etc.) at the jpc time the voltage was measured, you can end up with a transient low-charge jpc indicator which goes away the next time the voltage is measured. As you jpc have found, one way to force a new measurement is to turn the camera off jpc and back on again; I've found that simply half-depressing the shutter to jpc trigger the auto-focus, exposure metering, etc. generally works as well. jpc I've learned to ignore the transients. But as soon as the indicator goes jpc off full charge, and stays there no matter what I do, I treat it as a jpc signal to change the batteries at the next convenient opportunity. That's jpc almost certainly an overly-conservative approach, but it's cheap enough; jpc I carry at least a dozen extra charged batteries as well as the eight in jpc the camera and grip. I don't see the point in risking missing a shot by jpc trying to squeeze every last electron out of a battery.

*ist D problem at ISO 1600?
Hi everybody, I guess the wise people of the *istderhood can enlighten me about an issue regarding the low light behaviour of the D. When shooting at 1600 (with noise reduction turned off) every now and then the pictures show a cartain amount of striping, visible in the dark (or evenly lit) areas. There is no real pattern, just a certain amount of stripes (lighter and darker alternating) on a single shot, sometimes on two/three consecutive ones. This seems to happen at every speed 8ranging from 1/30 to 1/6) with no significant difference. Looking at Luigi's concert pictures (http://www.livejournal.com/users/ouij/) it seems, to me at least, to be an issue present in his DS too (I may be perfectly wrong, though...)

The battery indicator only shows full, half full or empty. Not very useful. I usually chang battteries whenever it does not show full.

RE: *ist D problem at ISO 1600?
Good question Shel. There is an indicator,but how secure it is im beginning to have doubts. The reason. I have a very fresh set of lith's in there now,about 50 shots on the set. I was at the farm this morning in the snow and i wanted to get a few horses outside all covered in it. I turned on the camera,wound up talking to someone for 2-3 minutes,then went to shoot and nothing. Battery indicator showed exhausted. I turn off the camer,then right back on,and it read full and i went ahead and shot 7 raws (only had a 128meg card) Temp was about -1 C.

RE: *ist D problem at ISO 1600?
How does one know when the batteries are getting low besides having problems with the camera? Is there a battery test or check feature?

Everything worked fine on it... except the battery indicator would flip out more often than not.

And I can't even give it a shot since my camera finds itself (yet again!) in Colorado being repaired. Has the be the 3rd or 4th time by now. What a drag. - jerome _ Jerome D.

I keep track of exposures. I get about 2000 on 8 lithium AAs in the camera and battery grip. If I'm close to that number and I have an important shoot coming up, I change them.

Re: *ist D problem at ISO 1600?
Jens Bladt mused: The battery indicator only shows full, half full or empty. Not very useful. I usually chang battteries whenever it does not show full. That's what I do, too. Other than that I've heard, that the indicator is unreliable if there's a battery grip attached, pehaps especially for certain batttery types (NiMh ?). I've only just got the grip, so I'll have to see how it behaves. I always use NiMH batteries.

I think the battery indicator just samples the voltage occasionally, rather than being a continuous meter. If the camera was busy (focussing, writing to the CF card, etc.) at the time the voltage was measured, you can end up with a transient low-charge indicator which goes away the next time the voltage is measured. As you have found, one way to force a new measurement is to turn the camera off and back on again; I've found that simply half-depressing the shutter to trigger the auto-focus, exposure metering, etc. generally works as well. I've learned to ignore the transients. But as soon as the indicator goes off full charge, and stays there no matter what I do, I treat it as a signal to change the batteries at the next convenient opportunity. That's almost certainly an overly-conservative approach, but it's cheap enough; I carry at least a dozen extra charged batteries as well as the eight in the camera and grip. I don't see the point in risking missing a shot by trying to squeeze every last electron out of a battery.

Re: *ist D problem at ISO 1600?
Of course I leave the batteries in the camera for multiple shoots. Lithium AAs will reliably deliver at least 2000 exposures when used with the battery grips. Of course I never travel without a spare set, and I have two bodies. I've had too many bad experiences with rechargable reliability. Lithiums are foolproof.

They lasted maybe 20 exposures before getting exhausted. Never again. I always have 2 spare sets of batteries and at least 1 gig extra of memory in a little case I take with me.
RE: *ist D problem at ISO 1600?
Gianfranco, While I as well have had problems with the battery indicator being reliable on the *istD, that may not be the problem. I have seen the striping effect at ISO 1600 and 3200 with good batteries in the camera. There have been several threads in the Pentax SLR forum in dpreview about this and one belief is that the striping may be due to the camera trying to write to the compact flash while also reading image data from the sensor into the buffer. I do not know if that is true but the only time I have seen the striping is while shooting soccer games when I may shoot bursts of pictures. In casual shooting (i.e. single frame shooting) I have yet to see the striping. I don't know of anyone actually running an experiement to prove or disprove this theory but from the anectdotal evidence it is at least plausible. Another thought is that it occurs with some types of microdrives. Having never used one, I can't say.

RE: *ist D problem (firmware?)
It is very slow because it is NOT writing direct to the CF. It is sending the entire file to the remote software on the PC which is then writing it back to the camera. Which means twice as much data going through the slow USB 1.1 link. As I said - they need a DIRECT to CF link. -Original Message- From: Michel Carrère-Gée [mailto:[EMAIL PROTECTED] Rob Brigham a écrit : Also a pain is that you apparently cannot save direct to the CF - all images have to go down the USB 1.1 connection which realistically means jpg only...

Re: *ist D problem (firmware?)
Is the flash problem with remote assistant operating camera? Handheld, mine works with flash up. And I just tested it with flash up, still works!

Worked fine... novelty value. Then... came back later to play. This time, I discovered that I had a problem - when the flash was flipped up (irrespective of any connection to the computer), AF would not operate, and shutter would not fire. Bummer hey. I'm sure it worked the first time I tried the new firmware. Works fine without the flash, whether plugged in to the puter or not. Anyway, tested a few things - resetting all camera settings, eventually decided it was a bug with the new firmware. S, I dug up my old 1.10 firmware, and installed that. Still the same problem )-: With the flash up the camera responds to nothing from the shutter button (or from the remote assistant shutter/focus controls) Even tried re-installing various firmware... Do I have to take my camera back and get a replacement? Pretty annoying to say the least. Anyone else with similar experiences, connected or not with firmware updates? David
RE: *ist D problem (firmware?)
OK, I think I got caught up in somebody else's thinking here, and didn't translate it into my own real-world use. For me, I don't care about sending images direct to PC as I am quite happy to write to card download on a firewire reader or to my flashtrax. The only use for me of Remote Assistant is just that - remote assisstance. Being able to set timer intervals and do extended autobracketing. In fact only really the first of those. And I guess as such I am not likely to be hamstrung by the download taking a ling time. I still feel it should be an option to write direct to CF (if only because it should have been simple to implement), but feel even more strongly for people using it as you say - in order to write directly to PC that not giving us USB 2 was a BIG mistake. Maybe the ideal compromise would be to use the card as a buffer - writing direct to that and having a background process trickling the stuff down to the PC. I bet that wouldn't be easy to implement though... -Original Message- From: William Robb [mailto:[EMAIL PROTECTED] Sent: 18 March 2004 14:34 To: [EMAIL PROTECTED] Subject: Re: *ist D problem (firmware?) - Original Message - From: Rob Brigham Subject: RE: *ist D problem (firmware?)

Paul, be sure to sharpen before you print. Pentax leaves that to you. Images directly from the camera are soft. Joe
Re: *ist D problem resolved
Thanks. I noticed that in my experiments last night. I had a shoot today for which I had intended to use film since I'm a newbie on the digital. But it was working so well last night I decided to use it. I filled a gig and a half of flash cards and am downloading the shots now. The couple I've looked at are nice. (One is a young lady in a thong raising her pants. Hey, it was an assignment, someone had to do it :-). I'll post a couple shots later for those who are curious.

Hello Paul, Glad to hear you got a working one. They are fun, aren't they!

It arrived today. I upgraded the PS firmware and shot a few pics. I tried it out with my studio strobes, PS and I'm very pleased. I was in the process of doing some table top with PS MF, so I just repeated one of the shots with the *ist D, a K 50/1.4 and PS the three strobes that I had been using with the 6x7. I resed up the PS result in PhotoShop to yield an 18x 11.5 print at 360 dpi and poured it PS into my Epson 1200. The result isn't as crisp as the prints from PS scanned 6x7 but the detail is very good. Of course there are better PS ways to res up the file. I think Genuine Fractals and other software PS are better at this than PhotoShop. I'm looking forward to working with PS this camera.
