Quick question about K5II magnification in picture review and live view
... just to be sure: The K5II (or K5 or K5IIs) offers 32 times magnification in picture review, but that clearly goes beyond pixel level; testing sharpness of some lenses today I got the impression that at 8 times magnification I'm sort of at a 100% per pixel view. Is this correct?
Or to put it another way: Is the 8 times review magnification the right magnification for checking sharpness of a taken pic (especially those taken with wide angle lenses - they tend to look awful at 32x magnifcation... )?
I'm a bit irritated because in liveview mode you get a maximum magnification of 6 times (with AF) or 10 times (with MF). So what is the real "100% magnification" on the K5II display?
Any info on that welcome. I think I read it somewhere, but can't put my finger on it ...
I think it goes like this:
The K-5 models have a 640x480 RGB screen (4:3) but vendors count each color pixel by itself:
640x480 x 3 = 921 600
Now the 3:2 image uses the long side horizontally:
4928 imager pixels / 640 screen pixels = 7.7
So right, the closest magnification is 8 (or is it just called 8 and it is 7.7 instead?)
we don't see that we don't see (eye's blind spot)
That sounds like a very convincing piece of math. Thanks indeed!
8 is about 100% Phil, Only know because this issue was raised once before.
