Originally posted by pepperberry farm I'd shoot each one for a solid month in the Single In Challenge - at the end of three months, decide which one's shots you like the best and sell the other two...
I second the motion.
I have M50f1.4/1.7/2/4. I've shot my month with them with APSC body and based on it I will let 1.4 and 2 go after I've shot an other month in FF with them. On condition that I get most of my 90€ and 30€ back from them. With these prices there really isn't any point to dump them at discount.
So my answer to your question is that I would keep M50/1.7.
