So, if we ignore the noise, AF speed and one stop difference of the two lenses, which one is then optically best?
I have read numerous tests, blogs and reviews that say the two are both sharp, contrasty and colorful (with the f2.0 being slightly warmer) however I have also encountered quite a few tests that have tried both lenses in Capture One where you can remove the distortion and vignetting correction done by software. And in those reviews it seems like the f2.0 lose, by a large margin, as the f1.4 is optically better corrected. As it is well known, software correction slightly degrades image quality. But will it be an issue?
Now, I don't have any of the lenses, so what are your thoughts if you have or have had both lenses.
And remember! Disregard noise, AF speed and one stop difference. I am only after the optically best lens :-)
