I think I'm staying away from canon macro gear, hate to say it. My 100mm broke again in less than a year (actual usage time was 3-4 months), & warranty was only 6 mos. What makes it even more frustrating is it's the focusing ribbon that "breaks" & I rarely have it in AF???!!!?? It might be somewhat tolerable if operation in manual focus was still a viable option, but it just throws an error code. If I remember correctly (?) someone here was having some type of repeating issues with the MP65 1x-5x lens. Add this to some of the posts I have been reading here about Canon quoting crazy cleaning/repairing prices.
The Laowa lenses have been getting wonderful reviews, some claiming sharper than the Canon 100mm??? I'm in manual focus 99% now so not much adjustment. I've checked the specs, my 2x rig currently (100mm + full set tubes) is a full 2.5 inches longer than the Laowa 100mm 2x. Can't focus to infinity either with the tubes attached, although I haven't had that need yet while shooting macro.
Sorry Archibald, this wasn't directed at your post it was just me venting on Canon.
