Roger Cicala and the LensRentals team recenlty opened up a Sony FE 135mm f/1.8 GM and came away quite impressed (even though the lens was returned with a serious issue).
This is a very well made lens. It IS built like a tank with robust magnesium alloy barrels, lots of long thick screws holding things together and nothing flimsy to be seen. The electromagnetic focusing motors, which were a weakness a few years ago, are now built like you could pull trucks out of ditches with them.LensRentals takes great care in ensuring your rental arrives in tip-top condition. Be sure to keep them in mind for your rental needs.The more subtle stuff, things like the neatly laid out flexes and reassembly markers, indicate to me that a lot of care was taken in designing this lens. Nothing has that ‘we can stuff that in this nook over here’ look.
It’s a great lens optically that is very well built.
