Originally posted by baro-nite Most of my macro these days is high-magnification with stacking. I have flashes very close meaning I can have them at low power and still shoot at low ISO, and I just like the look of the K10D at low ISO. (I suppose I should really do some controlled comparisons with the K-5.) More pixels doesn't help with this kind of macro, because you are nearly always working right up against diffraction limits, so I actually prefer the K10D's lower resolution for this. Plus it makes the stacking go quicker -- it's a computationally heavy process.
I see. Thanks for sharing your perspective and reasons.
I hear you on the computational angle. The very first computer I had was a Pentium 3, and I scanned an 8x10 photograph and something like 1,200 dpi. It crashed the machine repeatedly. I ultimately dug deep into the operating system and turned off every process I could to get the thing to run, and finally was able to scan the photo. It turned out real nice, but to view and edit the thing, or even print it, I had to play the silly disable the services dance to make it happen.
Today though, I have a CAD workstation I built to do 3d CAD and solid modeling stuff on and it has no trouble at all with extra high resolution images.
Of course I don't use it for anything else, it doesn't even have any software on it that is not needed for the work I do on it.
