  • Nice possible sequence: 7.5, 15, 30, 60

    I find the Oly 60 2.8 macro makes an excellent all round prime for its focal length, as well as being a great macro.

    I recently acquired cheaply a used copy of the excellent Sigma 30 f/1.4 as a near standard focal length lens.

    While idly considering something wider angled, I wondered about the Panasonic 15 f/1.7 among others. And then noticed a sort of geometric sequence of focal lengths. And if one were taking it further (and adding a fourth manufacturer) I guess the Samyang 7.5mm fisheye would continue the sequence as follows: .

    Samyang 7.5mm f/3.5 fisheye
    Panasonic 15mm f/1.7
    Sigma 30mm f/1.4
    Olympus 60mm f/2.8 macro

    So - speculating further - there's no native 120mm for M43 as far as I know. Maybe something like this https://www.pentaxuser.com/forum/top...0mm-f2-8-19124 could be used with a suitable adapter?

    :-)
