Very excited for this lens and anxious to see what kind of results it can produce. Looking forward to the reviews and your samples, Marco.
interesting that it’s the only EF-M lens to date to have a focus limit switch. I wonder why this is? Also, is there really that much benefit to limiting focus from 0.5m to infinity as opposed to using the entire range?
I'm surprised to see it on a Prime like this. The EF 135mm f/2L and the EF 100mm f/2.8L Macro lenses have this feature. So to the larger Zoom lenses. It cuts down focus travel times when shooting on subjects that are super close... so the lens isn't shifting constantly towards infinity focus. It certainly speeds up the process when dealing with closeup subjects to push for bolder bokeh. Examples of where it would be handing is if you are shooting pictures of pets with a distant background and you don't want to lens to wander towards the distant horizon. Probably not a bad idea but it's surprising to see on this particular lens. The switch has an Zero to INFINITY and a Zero to HALF METER option. So this switch is clearly designed to allow some very tight 9" closeups of flowers and close subjects. The Canon video claims it can fill the entire frame with a business card and that's something I simply CAN'T do with many lenses, including (and especially) the EF 50mm f/1.2L USM lens.

My EF 50mm f/1.2L and EF 85mm f/1.2L lenses don't have a focus limiter switch... nor does the EF 24mm f/1.4L lens. That's why it puzzles me. Either way, it's not something you may need to engage since there's an infinity symbol on the switch. But if you're doing creative work, it's nice to have the switch there to speed up the process and limit the focus to a closer range for those shots.

A 52mm lens (equiv) that can shoot just 9.2 inches from any subject at f/1.4 is going to be something to behold on the EOSM. I'm very excited to see some actual samples. Just WOW.
