K7 HDR hypothetical question
I guess the difference is that the HDR feature does not require any 'manipulation' to boost the image after capture. Therefore there is no increased noise or loss of detail. The three shots can also give you more latitude than RAW would have given you - you can pull back detail from images up to...

K7 HDR hypothetical question
Not a dumb question at all. The type of "HDR" where you use a single exposure and process three or more files from it is possible, from RAW or even from a JPEG, but there is a limit to how wide the dynamic range of the sensor is. You are not capturing all the information that comes through the le...

K7 HDR hypothetical question
Very much less than is recorded on the sensor or film, but the key to that is just how we compress the dynamic range to fit within the limitations of our materials. A colour slide has much more dynamic range than a print, and a monitor will have a similar advantage. This does not negate what w...

K7 HDR hypothetical question
RR have been thinking more about it. Still your idea doesn't seem to work since you need to read the whole sensor out simultaneously, very difficult to do that. You could however with your example with 1, 2 & 4 second exposure, you could use the mechanical shutter to freeze the sensor for a mome...

Just picked up my K7 today!
I would be interested to find out more on the K7 as at the moment I am not fussed at all which for me is quite strange. When the K20 came out I bought it within 2 weeks same as the previous K10. For some reason I do not have the same urgency to run out and buy one. I have no use for the HD video,...

Comparing Cameras
It's easy enough to spot the differences between the various Pentax dSLR cameras when it comes to ergonomics and handling. What I would be interested in is a comparison concerning Image Quality (IQ). After all, you learn how to handle your camera, whether it has one or two wheels, or the buttons ar...

Comparing Cameras
In perfect light, with an excellent lens, shooting RAW then you'll find even the *ist-D produces stunning shots (and that's at 6mp). Even for 18x12" prints the difference can be difficult to tell. Between the K10D and K20D at ISO100 there is some difference, but it's not massive. However, the K20...

Comparing Cameras
Thank you for taking the time, Matt. Apart from the useful extras, I understand that IQ-wise, the difference is mainly a better sensor (lower noise) in the K20D. I would imagine that the other components are mostly the same (AF, AE and SR). At least, the AF seems to be the SAFOX VIII in all bo...

Best way to clean dust off the K20d focussing screen?
The headline says it all. My sensor is spotless and I know we should never touch that with anything anyway, but there are a few little distracting specs on the focusing screen itself (or possibly the mirror). Obviously these don't affect photos, but are irritating. Any recommended methods to clean t...

Best way to clean dust off the K20d focussing screen?
Don't try and clean the mirror! leave that well alone. Cleaning the sensor with the right equipment is not a problem not is cleaning the focussing screen, which you can after all remove if you have the right tweezers, but never ever touch the mirror. Since the dust doesn't affect the photos you tak...

K7 Review Photo Monthly
Editor is no longer Will Cheung - he now seems to be freelancing for many of the monthlies instead. I thought this review was much more informative than the one (WC wrote) in Digital Camera mag and was generally very positive. Only issues were with metering (now tends to overexpose!) and IQ (j...

New K-7 adopters, what's your impressions?
Whilst trawling through the K7 manual i came upon "Catch in Focus mode" What a great idea! As i have a Bagfull of old K and M series Manual focus lenses with which i sometimes had difficulty in determining when a fast moving subject was sharply in focus or not (Usually not) before pressing the shutt...

GX20 Live View
So can anyone help me understand when and where I might have a use for this? 1. Taking a shot from an awkward angle or distance where you can't get your eye to the eyepiece comfortably or at all. Holding the camera above your head or out of a window, for example. You may not be able to see the LCD v...

K20D or K7?
Thanks for all your comments so far. Indeed the K20D does look like a very good deal compared to the K-7. I was originally planning to go for the K20D + 16-50 deal on SRS but in the time it took me to assess my budget the offer has since gone. I have looked at the prices for K20D bodies and they ...

K20D or K7?
If you are not s interested in video and wish to take advantage of some very good glass, I would suggest that the K20D would be a very fine choice. There do seem to be some issues with a bit more chroma noise coming out of the RAW images of the K7 which I suggest will be dealt with in their next fi...

Not a anti K-7 rant.........but
With great wonder I am following all the discussions about the new Kid on the block. And like most of the pentax users I think its great news there is another potentially great camera to choose from. But......after reading all the discussions about noise, frps, wb and in camera hdr I am asking my s...

Technology is a word that describes something that doesn't work yet. :wink: Like this one better though. We are stuck with technology when what we really want is just stuff that works. - I totally agree with you Martin that the camera's of the KD generation are still holding his own and that...

Not a anti K-7 rant.........but
The same was true for the previous 35 years until about 1990 when the first DSLRs came out, now IQ is more or less the same (taste and flavours) between the cameras like it was between types of film. The camera was just a method for exposing a film. The new Olympus is more or less the same as t...

Not a anti K-7 rant.........but
I've held back from adding to this thread to see where it went first! Will a K-7 make anyone a better photographer? On it's own, the answer is probably no. Will a K-7 make a difference to how you view your photography? For a lot of people, the answer is yes, definately. For some it may make th...
