MTF chart for the new Samyang 45/1.8
#2
It is very unlikely that you can compare the MTFs between different manufacturers.
If that was the case, we could close the site ;-)

The most obvious difference between those MTFs is about the line pair baseline that is supposed to illustrate the resolution - 30lp/mm vs 40lp/mm.
Samyang uses the weaker 30lp/mm approach which is boosting the corresponding line towards the top making it seemingly look "better".

Even if the lp/mm baseline is the same, there are still enough parameters to render a cross-comparison useless.
On top of that comes the fact that these MTFs are either simulated or from an optical bench - thus ignoring any side-effects from image sensors (protection filter, micro-lenses, etc.).
