I've just been playing with my K10D a little, set on 15sec exposure with no lens to see the sensor move. I find that if I shake too much the sensor just goes to one spot (usually some extremity) and stays there. If its just a little shake, it generally seems okay. Note I'm not talking violently shaking the camera, its quite easy to do just holding it not-so-still. Either there is something wrong (which I've wondered about anyway, due to some unpredictability in my SR observations), or perhaps this is the camera giving up because theres just too much shake. Though I would've thought it might centre the sensor in this case. Has anyone else had a look at the SR operation like this? If so, does this match up with what others are seeing?

Re: backup K10D or ... ?
Ops, sorry. My question wasn't very well phrased. With just one lens reversed (eg. with bellows), it doesn't matter what kind of lens you use, since there's no communciation between the camera and lens. My query was for using two lenses. For example a 200mm and a reversed 50mm stacked via the filter rings. Since the stacking reduce the working distance, there is potentially a problem when the straight mounted lens communicate focal distance to the camera. If this info is used in calculation of flash output, that is. In my experience, this problem is real, but it is only based on experience with one lens, the FA 100/2.8 macro. When using this lens with eg. a 50mm reversed, I get massive overexposure with TTL flash. When I use a A*200/4 and a reversed lens, it's OK. As Perry describes, there's still a consistent tendency to overexposure, but it is manageable. So my question is basically if this is an issue with my FA100/28 macro, or if it's a general feature of all FA lenses...:-) Cheers, Jostein On 12/12/06, Perry Pellechia [EMAIL PROTECTED] wrote: Jostein, I am not Mark, but I have used several lens reversed with the D and have gotten decent TTL exposures.

Re: Re[2]: Understanding ProPhoto RGB - or not
I didn't say no processing was done. You did. It was stated in one of the interviews with the engineers that Ken translated that they took opportunities to do signal processing due to the 22bit A-D that were not otherwise feasible. ... *before*. The common thought previously was that RAW provided unaltered A/D data of the sensor. That may or may not have been true, but at least it *could* have been. Now with truncation necessary, it *cannot* be true that a RAW file contains unaltered digitzed sensor data. Yes, but no longer presumed to be an unaltered digitized version of exactly what the sensor sees. It never has been. Transformations occur between photosite and digital representation in all cases that I'm aware of ... that's what all the custom signal processing chips in these cameras are all about, in part at least. I'm curious as to what these transformations are. The only ones I can think of off the top of my head are dark-frame subtraction noise reduction and possibly hot/dead pixel removal. For the most part, this is speculation since nobody but the image-processing software guys at Pentax know for sure. I'm just saying that not only is what I'm suggesting possible, it's rather *likely* given that they're trying to exploit the additional data available. But as I said above, the whole concern is nonsensical and pure speculation because you only get the RAW data the camera writes anyway. And the little working with the K10D that I have done so far indicates pretty clearly that it has exceptionally good image quality, even compared with the *ist DS which also has very very good image quality. The K10D has better 12 bit RAW data, in other words. I think that it is in part due to the 22bit A-D and whatever data massaging they do in that space, at least in part. That's the point though... even as it is, there are some user-adjustments that likely may affect the RAW file. Setting a different colorspace (sRGB vs. AdobeRGB), or setting a different white-balance will affect the conversion of 22-bit RAW to 12-bit RAW. That flies in the face of the idea that one can, shoot in RAW and not worry about WB and other color settings. If you want to continue to speculate for no particular reason, well, be my guest. It's not pure speculation. When I first got my -DS, I dove into the color management and white balance stuff. One of the things I did was add a white-balance (warming) filter on the lens and shoot a very cool color temp shot (overcast, evening approaching, etc). Bottom line was that after adjusting the WB in the RAW conversion between the filtered and unfiltered version, there was less noise in the channels that were captured approximating 5500K color temp. Bottom line: It was better to filter out (via the lens filter) the light that would blow out a single channel (like blue on an overcast day or red for a sunset) and then increase the exposure to bring *all* the levels up. Quantifiably less noise in the lower-level channels by doing that.

Just consider the scenario of a sensor which has acute sensitivity to near UV and near visible IR but very poor green response. It could feed into a 4 bit ADC but would still require a very wide colorspace to adequately describe/contain it's colour response.

Re: backup K10D or ... ?
The contact that transmits lens data is independent of the A contact.. Otherwise I would be able to manually set the SR focal length on the K10D. Adding the 1.7x AF adapter to any FA lens tricks the camera though.

However, can't you take the lens off the A position and fool the camera to not use the focal distance? On 12/13/06, Jostein Øksne [EMAIL PROTECTED] wrote: Ops, sorry. My question wasn't very well phrased. With just one lens reversed (eg. with bellows), it doesn't matter what kind of lens you use, since there's no communciation between the camera and lens. My query was for using two lenses. For example a 200mm and a reversed 50mm stacked via the filter rings. Since the stacking reduce the working distance, there is potentially a problem when the straight mounted lens communicate focal distance to the camera. If this info is used in calculation of flash output, that is. In my experience, this problem is real, but it is only based on experience with one lens, the FA 100/2.8 macro. When using this lens with eg. a 50mm reversed, I get massive overexposure with TTL flash. When I use a A*200/4 and a reversed lens, it's OK. As Perry describes, there's still a consistent tendency to overexposure, but it is manageable. So my question is basically if this is an issue with my FA100/28 macro, or if it's a general feature of all FA lenses...:-) Cheers, Jostein -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net

Re: Re[2]: Understanding ProPhoto RGB - or not
Bottom line: It was better to filter out (via the lens filter) the light that would blow out a single channel (like blue on an overcast day or red for a sunset) and then increase the exposure to bring *all* the levels up. Quantifiably less noise in the lower- level channels by doing that.

Re: my first shots with the Pentax K10D
Hi! Can you please elaborate further about the improvement over the DS part? - more pixel resolution - more dynamic range Har! Now, kind sir, will you please tell me what kind of improvement in dynamic range you observe so far? I have not done quantified evaluations, Boris, that I can quote numbers to you. I have taken test exposures in similar lighting that demonstrate to me quite clearly that I get more shadow and highlight detail to work with at identical exposure settings with the identical lens on the K10D vs the *ist DS. The differences are on the order of nuances, but when the base your comparing against is quite good to begin with, nuances count for a lot. When and if I do formal testing, I will probably put it on a web page for everyone to see and comment on, including the test methodology (as I usually do). I will be looking forward to that. Yes. So? It's the significant incremental advantages I was hoping for. What else is important? Price, may be ;-). It sounds like you are on the threshold of new understandings about photography. Keep going! :-) I sure will. The per-frame fine tuning will always be necessary for best results, depending upon how discriminating you are about image quality. How much fine tuning will be lessened by the consistency of the camera's systems, your understanding of their behaviors and your skill in using them. I don't try to get away from per-frame fine tuning but I admit that I am trying to minimize it. Having said that, I should mention that I placed a pre-order with one of the two shops that sell K10D locally. All are sold now here. The new shipment is scheduled to arrive roughly in a month from now. By then I will have decide if I want one, which as well I might. Cheers.

The adjustments and tuning provided by the 22bit A-D could be fixed and not affected by user selection of color space or adjustments to white balance, and therefore independent of what gets written in a RAW file. It will take testing to determine exactly what does happen to the RAW file with these adjustments, if anything. And to determine whether it is of practical significance to a photographer or to image quality, not just a quantifiable change.

RE: The Film Look
I was reffering to color or BW neg film. Can you get slides from digital files and are they any wider dynamic range than shooting slide film in the first place?

Interesting that with the K10D the 150x gives so little improvement over the 60x. Is the difference due to different brands of card? Or is 150x overkill for the K10D? You're entitled to your opinion, but I don't think 18% RAW/12% JPEG improvement is so little. Two digit percentage improvements I would deem to be significant even in a conservative evaluation. It demonstrates that the 150x card is probably close to the fastest card that will make a significant improvement in the K10D's performance, but I don't know of any faster ones to test against just yet. I would expect, given these numbers, that a 300x card would likely see the very small, single digit percentage improvement similar to the 60x vs 150x for the DS model. With 2G capacity 150x cards costing only around $43, and 45x cards costing $32, whether they're overkill or not is of little practical importance anyway. ;-) Godfrey -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net

The title was tongue in cheek :-) But why would you have to do it at ISO 1600? Before I put the flash on the camera I was testing SR doing some hand held macro. When I put the flash on I changed it back to ISO 100 but because of the way I was bouncing the flash off the wall ceiling, because I was shooting at f10 the shots at ISO 100 were quite under exposed. SO I switched back. To be honest because of the subjects texture any noise is invisible anyway. Cool shot anyway! Thank you.
