Dust removal
Hi Pete I had dust spots in Kenya but the inbuilt cleaning sorted it out no problem. Mind you though conditions were very dry and it was genuine dust rather that pollen. Pollen is very dificult to remove as it can be very sticky and typically has minute hairs on it that attach to nearly anythin...

Dust removal
Dust will adhere to the glass filter which covers the actual sensor for mainly one of two reasons. 1) Static, this should be easily cleared by the cameras dust removal system. 2) Sticky dust will be less easily removed by the cameras dust removal system. So, think about the environments where you...

Dust removal
I've had a few instances of hair or dust on the plate. The inbuilt shake 'n clean has done the job each time. I now have the camera shake the sensor on start up. it's easier than remembering to do the shake after changing the lens. Edit to add: just found that this did not work on a shoot...

Pentax 1.3 Sensor...
Just a little survey that I might want to pass on to Pentax...Who Wants a 1.3 Cropped Sensor and Why? What would be the benefits of such a format and would we be willing to spend the extra bucks to do so? Will Pentax develop or co-develop their own sensors? Best Wishes Ben ______

Not me. Not applicable. Not much. Not at all. Not likely. G (The difference between 1.5 and 1.3 is not significant, in my view.)

Pentax 1.3 Sensor...
What would be the benefits of such a format and would we be willing to spend the extra bucks to do so? It all very much depends on.... Coverage of the new DA* lenses, if they cover an image size not much bigger than APS-C, then there is unlikely to be a camera with the same chip size as the 1D ...

Pentax 1.3 Sensor...
I guess that the race will 'plateau' at 10-12 MP.... with more emphasis on image quality from each pixel They said that about 5MP, 6MP 8MP. In fact only 12 months back it seemed that all the camera reviewers were insisting that 6MP was enough for anyone and that anything above was doomed to failure...

It all depends on whether Nikon enters the 'full frame' sensor arena,....if they do then pentax and others will be obliged to follow.

Ben, Agree with George. Why would I want a larger sensor? What I want is clean, highly detailed images suitable for large printing. The *ist-D was great, the K10D is superb. It's dynamic range, smoothness of tones, and lack of noise that attract me - not sensor size. The current DA lenses are...

Ben, Thanks for the reply :) "DePressing Review" I think it was called around here :P That's interesting to hear... I sometimes get hung up about whether I'd get better results from a 5D or even 1DsII - but I suppose you can probably put my mind at ease :D I'm still blown away by the...

Pentax 1.3 Sensor...
It is quite clear from the specs for the new DA* lenses that they are designed for the APS-C sized sensor, so I think we can discount Pentax using a larger sensor, at least for a few years! Thier design philosophy seems to be that the APS-C sensor is good enough for 35mm equivalent work, and that i...

Pentax 1.3 Sensor...
That just about sums it up! The results from the APS-C sized sensor are superb at this stage and that can only get better in the future. As has been said, the 645D is the next logical step up, if there is sufficient demand for it. And that I suppose also depends on the final cost.

Pentax 1.3 Sensor...
I'd happily go for a sensor that had a different aspect ratio so that it had the same shape as an A3 size paper. There would therefore be more effective pixels to use, as you wouldn't have to chop off the ends of the frame for most uses. There's talk of a 1.3 factor sensor. I wonder if the ne...

Several places on the web are running 'official rumours' that Nikon will be using a 1.1 size sensor in it's new Dx3(?) pro camera to appear with or at the PMA show in orlando in about 10 days time. This makes it more or less a certainty that Pentax will make a larger sensor model, since in order ...

George, Pentax used to make FF lenses until relatively recently so it would not be difficult to dissinterr the designs,....indeed thay may have been keeping this very eventuality in mind. A larger sensor (than APS) would allow less noise at higher iso as this seems to have limited the 10 meg ...

I'd have thought that if Pentax imagined that they might be producing a 1.3 or a 1.1 sized sensor, then their new DA* lenses would be built with some lee-way, and they aren't! It looks like Pentax have nailed their colours to the APS-C mast quite firmly.

I agree with the idea that if you want a bigger sensor get the 645. If you really need a big sensor for "pro" stuff (whatever the word "pro" means...) a 645 is a logical camera.
