Been using this for the last couple of years. You can pick two lenses to compare. You will definitely find alot of surprises in lens comparisons. For example some of the Rokinon/Samyang lenses are sharper than some of the Canon L lenses and have less chromatic abberation. But there's other reasons to use a specific lens. Color Rendition and bokeh rendition are huge factors. But this tool is only for sharpness and purple fringing. And Bryan Carnathan does it well!!!! He also has detailed reviews!!!!
