This is a thread where a macro beginner is asking for advice. IMHO, it is ill-advised to recommend to someone like this to not go beyond F/11. Note that I simply invited others to try it for themselves and see where they wish to put the limit. (I do wonder exactly how big would one need to print a 24MP K-3 image for pixel level sharpness to become a humanly noticeable issue?)
Quote: But why did you scale them down by a factor of 2.4? Or was that crop?
I don't usually crop very much, and when I do, there's usually an indication of how much in the description. For me a heavy crop is 12MP on the 16MP K-01 or less than 18MP on the 24MP K-3. After that, I definitely scale down significantly - to usually less than half of the linear resolution of the original. That is because I offer my Flickr pics (un-watermarked) under an IMHO generous Creative Commons license (
BY-NC-SA). Under that license, I prefer to not offer the original, full-size file.
That being said, I'm trying to be as open as possible, posting links to my stream and samples, which so far I don't think we've seen from you. Anyway, in that spirit, here are two 100% crops from SOOC K-3 jpegs. These shots might not be "pixel-sharp", but I suspect you could print them quite large, as, again IMHO, even the 100% crops don't look too bad. Of course, YMMV.
