Quote:Don't need to read, I saw it for myself when I disassembled the 15/4 Macro "shift". There are a couple of design decisions you don't do if you want to have happy customers. The mount is not well made, needs two times a push on the mount release button. The shift lock doesn't lock, shift itself has 3 positions and the lever is flimsy at best and so on. Can't judge about optical design, but mechanical it's bronce age. lens hood is a new record in cheap mould making. Automatic diaphragm? clickstop aperture? Nope. No one will talk me back to Laowa.
I didn't intend to ;-)
That 15mm f/4 is a different quality than the "blue ring" series though. But even those are still not fixing the coupling.
