    Phase detect AF support.

    Has Olympus made any statements about how long they will continue support for users of Four Thirds lenses with future MFT bodies? I was a little dismayed to see that current support is limited to the OM D EM1. Like many others I have a large investment in Four Thirds glass and really can't justify starting all over again with new lenses. I have searched far and wide and can't find any Olympus statement about this.

    There is no official word but my speculation is that because so much has already been invested in the technology for the E-M1 and that others including Nikon, Canon and Sony have all adopted on-sensor phase-detection AF in tandem with contrast detection, it must surely be here to stay and may well be added to a wider range of models (Canon, Nikon and Sony already offer it on lower-spec. models).

    Re: Phase detect AF support.

    Thanks for the reply Ian. That is indeed reassuring, especially when one considers the cost of the 90-250mm f2.8 or the 300mm f2.8!

    Cheers,

    David.

    Don't forget that the E-M1's PDAF works with Micro Four Thirds lenses as well as the older Four Thirds lenses.

    Keeping phase detection focus on the "pro" body is most likely how it will stay. Not really saying much...but an E-M1 and grip is much easier to handle than an E-M10 or pen for instance on any of the legacy 4/3 telephotos.

    Re: Phase detect AF support.

    I was just wondering, when did Oly cease manufacturing the FT lenses? I see it is still possible to buy them brand new.

    Re: Phase detect AF support.

    Olympus has not officially announced that it has ceased manufacturing Four Thirds lenses. In fact they are on record as saying that some models remain officially 'in production' and if stocks run out they will produce new batches. The lenses that I believe they are referring to include the unusual lenses like the 35-100 f/2, 12-35 f/2 and 90-250 f/2.8 and 300 f/2.8 plus maybe the 7-14 and 8mm fisheye. The latter two now have Micro Four Thirds counterparts of course.

    In the end Olympus had to make a fundamental choice in order to survive and Micro Four Thirds was definitely the right way to go as even Nikon and Canon are now struggling to maintain sales. Olympus is now making a profit in its camera division for the first time in a long time (assuming I have interpreted the latest financial reports I have glanced at!).

    I don't agree with you on that because Sony, Nikon and Canon already offer on-sensor phase-detect on their lower-spec. mirrorless models. Olympus has a reputation for developing more advanced features and then adding them to cheaper models. When you consider that sensor production benefits from volume production in order to lower per unit costs then it's very logical for Olympus' next-generation sensor with PDAF to be featured on more models, especially as new lenses like the 300mm f/4 and Panasonic's rumoured new telephoto zoom really do need PDAF to work well. And existing MFT lenses already benefit from PDAF.

    But of course this is all speculation and we won't know until the next batch of new Olympus camera models comes out.

    Re: Phase detect AF support.

    Thanks Ian, yes some time ago I bought a S/H Canon 1Ds so I could use my collection of film era Canon lenses (I have a Canon EOS3 and 1n so I can still shoot film) but it is certainly a handful compared to even the Four Thirds bodies I have. A friend of mine is moving away from Nikon to MFT for its diminutive profile and I think this will become the trend so the days of the big FF cameras may be nearing their end as sensor technology advances.
