Difference in printing quality

One can nit-pick anything. I guess I should have (and thought I did) qualify the statement with "... in general..."
My apologies.

In general what I said can still be true. Even with higher resolution source images, the printing process may (or may not) actually retain the detail. It depends on the decision made about the resulting print and need.

Regardless, back to the OP's issue; a crop factor v.s. full frame sensor is not likely to be the sole factor on how that final images looks.

Like I said, it was a difficult and subjective question to answer. :cool:

FYI, here is some good starting places for determining resolution for printing.
I could not find the page I wanted, but this gives a rather decent start for what to think about. You can certainly search the Internet and keep yourself up for the next few days reading technical detail about what works and why (which again boils down to being somewhat subjective because no two eyes are exactly the same).

Resolution for print viewing distance

Another thing to add, is the medium you're printing on... glossy prints more detail than matte, since the ink tends to bleed more on matte paper. So printing higher resolution can be a waste. Even more so on canvas with rough texture. So instead of starting with 300dpi, you might be just as good with 150dpi.

Still, none of the relates directly to crop vs full frame.

I believe the suggested viewing distance for a screen that size should be more like 3-4m. You're going to burn your eyes out. :lol:
Although honestly, who wants to sit that far back when their entire field of view can be filled with video! Nice! :cool::cool:

Of course the bigger you print, the further back someone is likely to be when viewing the image, so the less resolution you need. (i.e. billboards have only a few "pixels" per inch) This is a very difficult and subjective question to relate directly to camera resolution.

Some would say it is hardly worth going above 10 MP, as you generally won't see much difference under normal viewing conditions regardless of the size printed.

Of course, FF also does not define megapixels. You can have a much lower megapixel FF camera than with crop.
Don't look at FF as having higher resolution.
I'd have to do the math, but I believe I've read that if the K1 has a 36Mp FF sensor, that would be slightly lower resolution than the 24Mp crop sensor in the K3, for example. (I think you'd have to go to 42+Mp to get similar resolution). Assuming your *only* criteria was Mp, the FF sensor might give your "worse" images. :-)

Unless you can define a need for FF v.s. Crop, there is no real need to change.
There may be reasons to go to FF. Plenty of reasons to stick with crop sensor, as well.

But printing size is not one of them.


You want sharp detailed images? Use good lenses.
Do not use a camera with an AA filter unless the need exists to reduce moire, etc...
If you don't need flash and subjects are perfectly still, use "Pixel Shift" to increase color resolution and sharpness.
Ultimately, get a medium format camera. The sharpness for the resolution is noticeable. But again it isn't the Mp that makes the difference.
