Dust on sensor
It's worth mentioning that no fluids should be used on the sensor assembly, except to slightly dampen whatever is used as a cleaning device. A friend of mine has ruined his sensor by using liquid on it, which got behind the filter and caused blotches as it dried. Cost of repair was enormous. It wasn...

Dust on sensor
Mornin' Rob. My first serious DSLR was the *istD which I took on safari to the Masia Mara. This got quite dusty during my 7 day stay. However I cleand it with a cleaning kit I bought at the then FOCUS show at the NEC. The *istD and the K10 had one hell of a THRRUUMMPP (that's the only way I can des...

Dust on sensor
Thanks all, I have decided to to buy a Pentax sensor cleaning kit for future use together with one of those puffer things. I also wonder whether I inadvertently caused the problem when I noticed dust specks on the mirror which I flicked off with a soft brush.

I'm trying to keep the equipment that I carry light, not my bank balance! Given the K mount is inherently FF already, I don't see that a Pentax FF has to be much bigger really. The only difference is the sensor size.

well there is one thing for certain if pentax bring out a ff camera wit less than 36 megapixels they may as well just pack up shop as the opposition is 36+ which means they are well of the mark of being 3rd in the sales table There is a rumour somewhere it will have the Sony 42 megapixel sensor. A ...

..but it will be much bigger and heavier than a K3. I highly doubt it. As Richard says, the sensor is bigger but that doesn't mean everything else has to become bigger. It may be slightly taller and perhaps a more pronounced hand grip to accommodate a larger battery but that's about it. Those who...

Come on everyone, don't be fooled by the images...it's the same 3d-printed facsimile that was shown a few months ago. So what if you can see the mount? they have to find a way of attaching the lens,.... It's not being fooled by the images. DOZENS of people have already personally handled it at a ty...

I don't go with what DOZENS of people said, I don't know why you emphasize DOZENS - but if DOZENS of people told you they saw aliens in the same room would you believe it? Except that... This was by Pentax reps. The same Pentax display area where the Pentax full-frame body was seen by the general pu...

Let's hope that enough of those asking for FF are actually serious and make it worthwhile for Pentax, but then again the buyers who are not on Pentax sites...

I have a growing interest in wildlife photography. The 300 F4 DA Star with the 1.4 HD tele adapter on gives the same field of view as 630mm on a 35mm sized sensor. The latest Nikon 600mm (for example) weighs 3.8 kg as well as being huge.

Bearing in mind it might have a 42MP Sony sensor I am thinking that whilst the subject might appear smaller it would give the opportunity for close cropping and still render a sharp image, In which case could you not still use your APS-C lenses to their full effect?

It would be a large crop, but assuming you don't actually need the pixel dimension aspects of the image (say specifically for large printing) then I suppose there's still worth in gaining from the other quality improving aspects of the sensor ...eg dynamic range. Raises the obvious question thou...

Yes, a detailed and helpful analysis, thanks Hirst, and info plus entertainment added in as well, cheers Algi :) I've said it before, but the imagined boost to subject size at telephoto lengths on smaller sensors is an optical illusion. No doubt it is compelling, as it appears cheaper and lighte...

Where all this falls down is when we consider the number of pixels. Yes, a FF sensor will have more pixels when the camera position is the same and yes the image remains the same for all formats, but in real life the FF sensor does not have more pixels. So taking the bike image, the bike fills th...

Thank you John as my head was spinning with more than relevant info for wildlife photographers. I get my APSC sensor circle dedicated 300 F4 has the same field of view (roughly at 5.4 degrees) as the 150 450 new zoom will have at full telephoto on the new 'full frame camera (at 5.5 degrees). Of ...

, but in real life the FF sensor does not have more pixels. Actually some of them do have more pixels. However it's not all about the number of pixels. The size of the pixels is important too. The Sony 12MP Full Frame sensor has really large pixels in comparison to most other sensors and gives i...
