    Hello

    I've just bought the G80 but I'm thinking about swapping the 12-60 with the Olympus 12-40 f2.8 pro - does anyone else use this lens on their Panny bodies ?

    Just interested in the opinions of users...

    thanks

    I think @T N Args@T N Args does, if I'm not mistaken, having used it with the GX7.

    Prior to the GX85, I think most Panasonic users might have been a bit hesitant to go for it instead of the 12-35 since Panasonic's IBIS implementation was not as strong as Olympus', and the 12-40 doesn't have optical image stabilization the way the 12-35 does.

    Now with the G80 I wouldn't think twice about it, really, it should be totally fine. Image stabilization may be a little bit behind what you're get with the Dual IS system compatible with the 12-35, but if you like the size, features, and optics of the 12-40 more, then I can't see much in terms of disadvantages.

    I have the 12-40 and use it on a GX8. Works great, better than it was on an EM5. IBIS on the GX8 isn't as effective, but should be better on GX85. Focus is fast and accurate. I had the 12-40 when I bought the GX8, otherwise I might have opted for the 12-35 to take advantage of dual-IS. Size and image quality are so similar it doesn't make sense to switch...

    I'm a bit confused with the dual IBIS - do all lenses work with it but only a couple work with the new IBIS mrk 2?

    Only Panasonic lenses with in lens OIS support the Dual IS, and currently only 2 lenses (12-60 & 14-140 II) support the Dual IS 2 on the G85/G80. Firmware update should be available for more lenses soon.

    Actually I bought it in a kit with my E-M5 II, and haven't tried it on my GX7. Sorry!

    I think Panasonic have been somewhat optimistic, in regards to which lenses are actually upgradable to dual is. I would base my choises on the lenses that are currently compatilbe.

    I shoot with the 40-150 pro on the g6 with no IS available and there is no problem, so don't think you need to be concerned with the 12-40 on g80.

    I've used the Olympus 12-40 PRO on the GX85 with no issues ... the results seem at least as good as the 12-40 on my E-M1.

    So, I know I keep asking about this, but how does the C-AF on the GX85 with the 12-40 compare to the same lens on your E-M1?

    Sorry, I have not yet tried C-AF with the GX85.

    I would expect certainly worse.

    Continuous AF is the biggest advantage that PDAF has, and until the E-M1 II, the original E-M1 is the only M4/3 body that has it. Panasonic's DFD uses phase-like algorithms, but it requires Panasonic's blur database, so with an Olympus lens you can certainly expect the GX85's performance to suffer.

    Unless you're doing video, though, I can't think of that many circumstances where you'd need to use C-AF with the 12-40mm. Depth of field is pretty generous at f2.8, and S-AF is always really fast.

    I've often thought about this, and I'm not sure what to think. Only guessing, but lets take say a 35 mm f/2.8 lens, of either brand, wouldn't the amount of blur be the same? And still give an indication as to how far out the focus actually is? I've never tried any off brand lenses myself, as I'm personally a big believer in Canon lenses for Canon camera's, Panasonic lenses for Panasonic cameras etc etc, so can't make any educated guesses

    I use it with GX85, no problem whatsoever. AF is faster than my Panasonic prime lenses, and IBIS works really well both during video and stills.

    I use the 12-35 on my GX8 and it is a great little lens.

    To be clear, I wasn't really asking better/worse, I was asking "usable/not usable". For example, the C-AF on my E-M5 might as well not even exist for how useless it is.

    In that case, there is zero reason to expect C-AF on the GX85 would be better with an Olympus lens than what you're experiencing on the E-M5 II.

    Or whatever, same difference, really.

    They're both contrast detect bodies. The E-M1 range improves C-AF using on sensor phase detection. The Panasonic range improves C-AF using special contrast detect algorithms that are proprietary to their lens range.

    If you need C-AF, get an E-M1, E-M1 II, or use newer Panasonic lenses on newer Panasonic bodies.
