For those that seem to have missed it.

Im unsure, when Ive cropped to get a similar viewpoint the megapixels then become lower. Im talking soft in print which is what Ive found. I cant print as large and details look soft. If uncropped the full frame image is awesome

One consideration is that, as exemplified in prints made from film, that the detail resolution in the final print needs to exhibit at least 5 line-pairs per millimeter (of print) in order for viewers to perceive that print as 'sharp'.
Translate that into pixels and you need at least 11 pixels per millimeter of print or about (assuming Nyquist correlation of pixels:detail) 128 pixels per inch of print.

Smaller pixels don't make things less sharp. Aggressive AA filters and glass unable to resolve to the pixel density when one pixel peeps could be issues however. The 150-500 isn't the greatest at resolving detail, so that is the issue here, not the 7D2 pixel density/size. The Sigma 150-600 is a better lens and does a better job.

I have only used the 150-500 once, I've yet to print with it, Im talking with L lens and the Tamron 150-600 which I've found tack sharp. I sold it though
