I received this email form the people behind the “The Ultimate Test of Lenses” crowdfunding campaign that just started (click on images for larger view):
All the current tests you can read in internet use a camera to test the lenses, but in this way you cannot measure the real performances of the lenses. Our method is different: we test each lens by itself, we use an MTF optical bench, so the performances we measure are real. And our software shows how the performances change according to the different sensor’ size. The interface is very interactive, you choose the aperture, or the focal length, and you see how the performances change. You can compare different lenses, very easily.
As an independent laboratory, we do no accept advertising. That guarantees even more our independent judgment. At present we achieved a beta version, and we launched a Crowdfunding to complete our work.
Our laboratory MTF Lenses LAB was born more than 30 years ago and we have online a database of about 450 lenses, that we constantly enlarge.
