The pixel war
I think the move to the 24MP Sony sensor is almost inevitable for Pentax's next top model... an exercise in 'keeping up with the Joneses' rather than improving print quality.... [...] I see a problem for Pentax in being pretty much confined to using what ever sensor Sony puts out. Are there ...

There are more sensor manufacturers than Sony and they will all want to sell their sensors. I think Sony, Toshiba, Samsung and Kodak all make sensors and maybe many more.

There are more sensor manufacturers than Sony and they will all want to sell their sensors. I think Sony, Toshiba, Samsung and Kodak all make sensors and maybe many more. I was mostly thinking APS-C sensors. Are they all in that game? When people talk about "the next Pentax DSLR" it seems to be expe...

I would wish there where more players on the market, with todays technology they could make a very good 10mp sensor that would be excellent for the rugged compacts. Who need 16mp from a camera with a mediocre lens? Taking pictures underwater you would rather want the best possible result at higher I...

So all round what would you say would be the ideal number of pixels to produce the best quality photos in a digital slr. A freind of mine who does weddings and studio portraits once told me if his fuji S5 pro was a little more advanced he would not purchase another camera I think I am correct in say...

[quote:3496ace15f="Mike-P"]I still think my K10D produced slightly sharper results than the K20D/K-7/K-5. For me it's a trade off against being able to crop a lot more, especially when shooting aircraft/birds etc. Mike, I wonder whether this is due solely to the change in sensor to CMOS?? Regar...

[quote:3496ace15f="Joe S"]Nikon is putting money into making their own sensors? /quote] They say that about the D7000 but it's a sony in there though, maybe adapted. Which is the same sensor used in the K-5 I believe.

From my limited understanding there's another way to get some indication of why the megapixel race is suspect. That is to use pixel density - how many pixels per square mm for eg - (as done in past reviews on another forum) as an indicator of why the race can't go on forever. Pixel density is ...

I think some are to focused on size. 10mp and even 6mp is enough for most but even with 20mp sensor the total light gathering capability stays the same, yes the pixels on their own will be less "quality" but in their totality there shouldn't be much difference.

It depends on the lens and the aperture but with really really really good lenses we could go up to 40MP or even 50MP with APS-C. Is that really true? Even with current sensor resolutions, diffraction from the aperture ring is starting to limit the sharpness. A back-of-envelope calculation with ...

Now the Q becomes interesting
Hmm wonder if there's a glass element to focus the lens down onto the tiny sensor? Or is the illustrated DA40mm converted by the crop factor into a very fuzzy supertelephoto? :lol:

I am sure there willbe an optical element that will reduce the image circle to the sensor. If there isn't, the lenses just won't be sharp enough for such a hefty crop.

Now pay attention Bond.....this button operates the shutter and this ...well you get the idea .....brilliant. What a non-sony product in Bond characters hand? Sony lawyers would have a field day!

Q at ISO1600
No detail anywhere, soft and plastic looking -- even at a small web size. In other words it's exactly as one would expect of aggressive in-camera NR applied to a small sensor. Summary: Not a camera for photographers but a nice toy for gadget-lovers with money to burn. Exactly as I .
