Quote:the lenstip results are around 20lpmm lower than the ephotozine results at both the long and short ends:Uhmm yeah. ~12mp for the E-PL1 and ~20mp for GX8, and you compare how much line pairs per mm the sensors can resolve? Not really something to do....
lenstip ~60 ~40
ephotozine ~ 79 ~65
(I converted the ephotozine results from lw/ph to lwmm by dividing by 17.3mm for the sensor size and divide again by 2 for line pairs to line widths)
The very best mft lenses get to around 80lwmm acording to lenstip, so the result of 79 sounds plausible at the short end, and 65 woudl be good at the long end.
one thing to note is that the lenses were tested on different camers - ephotozine used the GX8, where as lenstip used the olympus E-PL1.
Also, you can't compare results like that from site to site, without knowing if their workflow is exactly the same. In the same vain, you should not compare PZ results and Lenstip results like that....
