In the link of multiple test images it is clear to me the CF39 has better separation of fine detail.
The new 100L is sharp/est(resolving power), the 180 is also very sharp. Sharper than the older 100Macro.
The Leica macro Elmerit R100 is sharper than both, well on par with the 180L. Its maybe just as sharp, but the Lieca has more contrast.These I base on tests I did some time back between the 180 vs the older 100 vs the LeicaR100
The Canon file is actually "warmer", less blue. Not colder...to my eyes Erik.
The Hass is "colder" with that ting of blue-purple-magenta.
The unsharpened Canon image shows the mix in separation on the pliers teeth. The contrasts start to mix. It can be lens perhaps?
If any of these are possible....100L or 180L, or if available the Lieca Macro El-R100...I would love to see a test with them vs a Shneider or Rod digitar/digital lens Macro on the CF39.
Thank you for the testing! Look forward to more if possible.
