Re: CMOS sensor for MF
The line between the dots (that Dario is connecting) is that the manufacturer that is making the CMOS sensor to be used in the Hasselblad is SONY. That is not insignificant. http://www.pocket-lint.com/news/126702-hasselblad-reveals-first-medium-format-cmos-sensor-opening-the-door-for-other-photography-brands While every company wants to make a profit on everything that they make, the camera body is (in essence) the razor that can be given away at cost in order to sell the razor blades (lenses, grips, flashes, and other accessories). If there are no bodies there is no demand for those. It also provides a bragging rights territory. If Pentax comes out with a camera that closely matches the functionality of the Hasselblad at a fraction of the price, then we are back to occupying the same territory that made the Pentax 67 and 645/645n such popular cameras with the medium format demographic. It is worth remembering that the new PRIME III (Fujitsu image processor) has the capabilities to handle the input from a medium format sensor. And a CMOS would have video capabilities, meaning a whole new video market for Pentax 645 lenses. Add in the other things that Pentax has learned from the K-3 line (and before) and you have the potential for a separate processor to help with exposure and white balance, improved AF performance, and perhaps even the adjustable AA of the K-3 (or no AA at all, like the K-5 IIs).

Re: CMOS sensor for MF
In thinking about it, another interesting part of the MF sensor company being SONY is that there have been no rumors of Sony-branded cameras in the MF space (at least to this point). With their other sensor sizes, there is a bit of a conflict of interest: Use it in a Sony-branded camera and give it a lead time in the marketplace before allowing other companies to put the sensors in their cameras. But if Sony has no dog in this fight (if you will pardon the expression) then it is in Sony's interests to sell as many as they can produce. It is doubtful, in my mind, that any one company (like Hasselblad) could dictate terms that would keep other manufacturers from getting their share of the sensors they produce. If that is true, the question is whether Ricoh will be different from Hoya when it comes to paying the price for a first generation product rather than wait for the component price to come down. I don't think there is any question that a 645D II will be coming out sometime in 2014. I think putting a CMOS in makes sense, but I'm wondering if it can be done at the original price point of the 645D (which was $9995, if memory serves).

Re: CMOS sensor for MF
In what way is the K-3 not keeping up with state-of-the-art APS-C DSLRs? In fact I think it's a category leader presently. And the other current models: pretty much the same story in each of their respective categories. The only category where Pentax isn't keeping up is FF, which is a mythical one only kept alive by the whinging fanboy base.

Pentax has kept up quite well in APS-C. Obviously they've chosen not to play in the 24x36 arena, so keeping up is irrelevant. They haven't kept up in pro video either.

Re: CMOS vs. CCD colours?
2009/7/29 Ralf R. Radermacher fotor...@gmx.de: After using a K10D for a few years I find that the colours I'm getting from my new K-7 are a trifle odd, to put it mildly. Particularly my sky colours now look like 1950's bathroom tiles. Some awful cyanish cast that I have only had with the K10D in severely overexposed shots. Grey sky comes out with a distinct blueish cast. I'm shooting RAW and talking about what I get to see when I open the RAW files in Lightroom, with the same settings and exactly the same way I've done with my K10D files before. The camera is set to AWB, just like the K10D, as well. Colours space in both cases is Adobe RGB. Any suggestions? If you're capturing RAW format, whether DNG or PEF, color space setting in the camera is irrelevant. The issue is a camera calibration issue. Nothing to do with the technology of the sensor, or everything depending upon how you want to look at it.. but the difference between CMOS and CCD is not relevant. The issue is that Lightroom does not have any calibration tables for the K7 as yet, AFAIK. So the thing to do is get the DNG Profile Editor, shoot a couple of controlled tests with a Macbeth Color Checker or equivalent, and create a good calibration profile for it. Install that as the default to use when processing K7 RAW files and your colors should be accurate. -- Godfrey www.gdgphoto.com www.flickr.com/photos/gdgphoto www.twitter.com/godfreydigiorgi -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

I haven't been following it specifically on that count. It would also be interesting to hear if there are differences in the calibrations with out of the camera DNG vs PEF files too. In the end, however, pick up the DNG Profile Editor and create a calibration file that you like, set it up as the default, and you should be good to go.

Re: CMOS vs. CCD colours?
Ralf, Do you shoot PEF? If you do, maybe it's worth an exposure to test if DNG is any different, just to test if the software has got the file format wrong. Notice also that Pentax has sometimes been criticised for producing a magenta cast in low colour temp settings, and with the K-7 there's a menu option to turn this on or off. That may make a difference for your nightscapes, at least. I'm sorry I don't have the K-7 close by right now. I suspect you'll be able to dig out the exact number of that setting before I do.

PSCS4 supports K7 RAW files, and they open looking very normal and nice in that software's ACR converter. The k7 files generally don't require as much tweaking as did those from the K20D, although that's primarily the result of more predictable exposure.

Yes, CMOS permits a slightly better fill factor. CCD is, from what I've read, inherently less noisy, but the fill factor of CMOS may make up for that. It certainly seems that the cameras with the best noise performance are CMOS these days.

Both have quite high noise levels given the size of their sensors. I think this is a case of pixel density. The Nikon D2X is 12MP on an APS sensor and the Sony is 10MP on a smaller-than-APS sensor.

Re: CMOS
It's more a matter of exposure evaluation than image processing, Shel. You need to stuff the highlight areas where you want detail up as close to saturation as you can get without hitting the saturation level, which often seems like overexposure to a film camera shooter, and then adjust the RAW conversion curves appropriately. That gives you the most data to work with in shadow regions and the least noise. At high ISO settings, dynamic range is reduced so it becomes more essential to get enough exposure in or bottom-end values are swamped with noise. On Oct 2, 2006, at 4:18 AM, Shel Belinkoff wrote: You've hit upon one of the things I don't like about the DS and that is noise in the shadows unless you bring the exposure up a bit.

Re: CMOS
In general, the differences between CCD and CMOS sensors today are more important to the hardware/manufacturing process then any benefits of one type over the other are to the photographer. How a specific design is implemented and built into a camera affects the photographer much more than which type of sensor it is. Canon's made a huge investment into CMOS manufacturing and it is working well for them. Sony produces sensors with both technologies and I haven't seen much evidence to say that their CCD sensor products (Pentax, Nikon, KM aka Sony, Olympus, etc) do better or worse than the Canon CMOS sensors do in any way that is significant to a purchase decision. I judge the cameras I buy based on the total package, not specifics of component implementation.

Re: CMOS

Re: CMOS
Shel, The shoe on the right is the original, the show on the left has had the corrections done. There is no real detail in that area, it's all Zone 1, but the noise makes you believe that there is detail there. To obtain more detail on the inner sole of the shoe, I should have given it 1 to 2 stops more exposure, then dealt with the highlight values that would have been dangerously close to saturation. It's always a trade off. The film or sensor only has so much dynamic range to work with. The inner sole of the shoe has no significant or interesting detail to me, so I let it go black so as not to burn the Zone IX details which I wanted. (This is only a 1:1 section of the full frame!)

Re: CMOS
It's interesting but you get both views from various reviews. I've seen reviews that will flat out say that the Pentax D series cameras have lower noise characteristics than Canons and others that talk about how noisy Pentax DSLR are at high ISO. The only Canons I've seen high ISO output from were D20s and my brother's digital Rebel, (don't even ask). The D20 output is extremely clean but don't seem noticably cleaner than my D and DS at any particular ISO. I don't think my brother has actually taken his DigiReb, beyond ISO 100 and uses the built in flash for most inside shots, and to think he never even had a flash for his Minolta SRT 101.

Re: CMOS
--- Christian [EMAIL PROTECTED] The lack of noise at high sensitivity is something people claim as an advantage for CMOS. Supposedly a drawback is that they suck more power. Actually, it's the opposite. CMOS use much less power than CCD but they have higher noise levels. Canon CMOS have very low noise levels because of a proprietary noise elimination circuit that is patented by Canon. This type of technology only works with CMOS (because of the way the data gets off the sensor in a CMOS as opposed to CCD) but anyhow it is proprietary, patented technology that nobody else can touch. Aside from the Canons (all Canon D-SLRs but the D2000, D6000 and 1D) the only other large-sensor CMOS cameras are the Nikon D2X/D2Xs and the Sony DSC-R1. Both have quite high noise levels given the size of their sensors. New Doug __ Do You Yahoo!? Tired of spam? Yahoo!
