I think I paid $13 for my Vivitar 55, but I almost never use it. Good for macros, though.
Another review of Vivitar 55 f2.8 Auto Macro
The Olympus Zuiko 43 (not m43) 70-300 is an old macro lens (140-600mm eq.) - it really gets close, from far away.
See this video for examples:
200mm F4 Canon FD Macro

No.
Let's say I have an insect that is 3mm long. A 1:1 macro will project an image on the sensor that is 3mm long. That does not change.
If your sensor is small, it will fill more of it, if it's large, it will fill less.
so you are saying: if I mount a 50mm 1:1 macro on a m43 I get 100mm 2:1; if I mount a 50mm 1:2 macro on a m43 I get 100mm 1:1, right?
1:1 is always the same, just means that something is as large on the sensor as it is in reality.
But a smaller sensor will fit less reality, of course ;-)
Regarding the two versions I can only comment on the old Tamron, which I really love.
Vivitar 55mm fd fit macro is very sharp and dirt cheap
How does mounting an old macro lens on a m43 camera affect its parameters? Canon FD 50mm macro 3.5 1:2 on a m43 camera is effectively 100mm right? What about the 1:2 magnification? Is it somehow affected by the FD to m43 adapter as well?
I am a beginner to macro
There are two types of Tamron SP 90mm 2.5 ... Witch it better ? Early or later ones ?
