K-x Bulb mode write-time slow?

Firstly, I'd say you have a better chance of getting an answer if you directed your question to Pentax in Japan - the UK office are a nice bunch and very approachable but ultimately an outpost where I doubt they have any more design input than we users do. I'm sure they'd pass your query on but they...

K-x Bulb mode write-time slow?

I don't use any non-Pentax DSLR's but a quick Google shows similar comments about the inability to turn off DFS on recent Nikon models (all the CMOS ones basically). I can turn DFS off on my D700 (which has a cmos sensor) - I haven't taken any astro shots, but in general long exposure use it doesn'...

K-x also for experienced photographers?

My suggestion would be the K20D with the 18-55/50-200WR. At the end of the day, it uses the same sensor as the K-7, and if your budget can't stretch to one, the K20D is still a great choice. The K-x is a mighty-fine camera, but I would put the weather sealing first and foremost if they live an...

K-x also for experienced photographers?

Hi Pete - are you sure? I was under the impression that the K20D and K-7 had the same sensor.

K-x also for experienced photographers?

Yes, they're not the same, but are more similar than I was remembering. From http://www.dpreview.com/reviews/pentaxk7/: "Updated sensor with four-channel readout". The four instead of two channels make it faster. The image quality is pretty similar, and the resolution is the same.

K-x also for experienced photographers?

To answer the OPs original question (from a K-x owner's perspective), I'd say a definite 'yes'. The K-x is easily the most sophisticated SLR I've ever used (and I'd consider myself 'experienced', though not with dSLRs, till now). Unless your d-i-l was using a very recent analogue SLR, I'd expect her...

Serious noise in low light

Maybe I'm being dim - but speaking as a fellow K-x owner (who's quite stunned by the low level of noise, and generally excellent low-light/high-ISO capabilities of his own K-x)... I'm not sure I can quite see the noise you're referring to. That's not to say it's not there, mind. You could be spot...

*istDS to K200d

200 ISO is the "native" ISO for these cameras, so I use that wherever possible. Setting 100 ISO brings electronics into play to adjust the expoosure, so nothing is gained. In practice you should be fine using 200 or 400 ISO. SR is such a boon that I think this alone justifies the use of the K200D...

*istDS to K200d

Do what I do Andy - dedicate it to M42 lenses as I have with my *istD - I then have instant access to about 12 lenses and the bellows and the tubes and teleconverters all with screw mounts and great quality. Or infra-red, I believe they don't have a sensor filter that cut infra-red so much as the ca...

*istDS to K200d

Like Jon says it can be just a filter like any other lens filter but you can also convert your camera by a specialize shop, they will place a permanent IR filter infront of the sensor instead of the lens so that you can see something through the viewfinder :) Here is a non typical IR photo of min...

kx images soft?

Don't forget the sensors are very different. The K-X has a CMOS sensor and a bit more pixels, at lower ISO's the K10D will be sharper when looking at 100% pixel zoom, it can be just the difference in the sensor. With the K10D the optimum ISO was 100 and 200 with the K-X it's closer to the 400 so u...

kx images soft?

Well I took some shots today and I don't think they are as sharp as they were with the K10D. I used my 77ltd and the images are disappointing. From what I have read on the internet the sensor is as good as the sensor in the k10 so shouldn't the raw image quality be the same? Has anybody else h...

The files are raw. The camera was up for srgb so I'll change to adobe rgb. Colour space doesn't matter with RAW because it doesn't have one :wink: I used my 77ltd and the images are disappointing. From what I have read on the internet the sensor is as good as the sensor in the k10 so shouldn't ...

..so shouldn't the raw image quality be the same? I've read over that part. If you mean the quality of the file system then yes most likely but the capture quality of the sensor is different though.

From what I have read on the internet the sensor is as good as the sensor in the k10 so shouldn't the raw image quality be the same? Has anybody else had a problem with image softness on with this camera.??? Try taking test shots on a tripod, using mirror lockup. It might just be possible (and I'...

kx images soft?

[ your technique hasn't adjusted to the much lighter body yet? That would explain why you notice the problem more on the FA77, since with the much narrower depth of field any camera movement issues would be much more visible. This is a good point and could be the reason. Here is a review about ...

K10D Back focusing Issue

Back/front focusing can occur with manual-focusing when there is a misalignment with the focusing screen or sensor. Then what appears to be in focus through the viewfinder is not in focus on the photograph. There also can be an error with the focus confirmation system (the green hexagon indicator...

photozone, Samsung NX and Pentax

One thing to bear in mind is that the NX10 is not a conventional EVIL: it has an updated version of the K20D's APS-C sensor. I suppose Klaus just didn't want to have a new lens review section with only one or two reviews in it. That though!

Weird behaviour of K-m dust alert - any ideas?

My K-m has started doing some odd things with the dust alert function: If I check with a zoom set to 50mm or wider it comes up perfectly clean. If I check with the same lenses set to 70mm/80mm I see horrible marks everywhere (which seem to be in different places every time I try). These are my...
