This lens is one of the few I am interested among the MFT lenses.
It would be nice to know how the lens magnification changes with the distance.
For example, what is the lens magnification at 70 cm (the MFD of the 40-150 F2) and 140 cm (the MFD of the 300 F4)? 300 f4 = 1:4,2
40-150 f2.8 = 1:4,76
Sorry, I did not make my question clear. I meant "what is the M.Zuiko Digital ED 90mm F3.5 Macro IS PRO lens magnification at 70 cm (the MFD of the 40-150 F2) and 140 cm (the MFD of the 300 F4)?
The specs indicate Maximum image magnification 1.00x and 2.00x(S-MACRO) at the Closest focusing distance 0.250m and 0.224m(S-MACRO), respectively. When the focusing distance is longer than 25cm, the 90mm Macro lens magnification should decrease. I wondered how much it drops from 1.00x and 2.00x(S-MACRO)?
To ask this differently: which of the two lenses one should use at 70 cm: the 90mm Macro or the 40-150mm F2 to get more of a macro subject in the frame? Also, which of the two lenses one should use at 140 cm: the 90mm Macro or the 300mm F4 to get more of a macro subject in the frame?
In real life, it can be difficult or impossible to get too close to some macro subjects (e.g., an insect). Then, shooting from a longer distance (for example, 0.7 to 1.4m) can be more convenient. Then, the practical question is which one of the available lenses has the best image magnification at such distances?
