So I am looking for a 1:1 macro lens. My options that I can think of within my 500 euro budget: A Sony 30mm for my A6000 (good reviews, price is good, AF too) A Sony 50mm for my A7 (no reviews, price is 3x the 30mm and outside budget, AF) A Sony 90mm for the A7 (at that price? No!) A Canon 100mm macro (std EF or the L) mounted via my Fotodiox (good reviews, price s/h is okay, slow AF) A Rokinon/Samyang 100mm macro (good reviews, price new is acceptable (but 2x the Sony 30mm), MF (don't mind)) Extension tube for Sony 28-70 zoom on the A7 (price very good! No idea about resulting DOF, image quality, magnification, AF (some tube versions - e.g. Neewer - state AF is retained)) Extension tube for Vivitar 70-150 Canon-fit zoom on A7 (but this adds a tube to an adapter, no idea about resulting DOF, etc, etc, and MF). Really not excited about this one apart the very cheap price of tubes. Buy a cheapish Sony or 3rd party prime (e.g. Samyang 85mm) and add a tube. Any other options to suggest? (I also have the Sony 70-300G but putting that on a tube is probably insane....?) And any comments on the options above very gratefully received.
