I am done with wide because i ordered 65mm yesterday, so the only one left is the longer one.
I have 180mm on my RZ, and it is so great for portraits, so i feel either go with Macro as this is the only option i don't have on RB or RZ or even my Hasselblad 501CM, but i don't know if i should get Macro for RB so i can use it on RZ sometimes or better with RZ even i don't like RZ battery issue? RZ is giving me the easiest way to shoot with tripod, clocking the shutter, and dialing with the back and focusing screen, i tested RB few days ago for first time and it wasn't easy as RZ, so i may keep RZ in use with RB if not more.
Also i was thinking about tilt shift, but which one is better, getting a tilt/shift lens or a tilt shift adapter?
