    There are only 4 native Micro 4/3 lenses with servo zoom support at all, and none of these have a very wide zoom range:
    • Panasonic 14-42mm f/3.5-5.6 PZ Power O.I.S.
    • Panasonic 45-175mm f/4.0-5.6 PZ OIS
    • Olympus 12-50mm f/3.5-6.3 EZ
    • Olympus 14-42mm f/3.5-5.6 EZ

    None of these lenses are designed with ENG-style lens bodies with zoom rockers (two of them are pancake lenses). I think they were mostly geared toward casual hybrid shooters, and they were all released several years ago (2014 or earlier).

    Panasonic did develop a 13x f/2.8-4.5 servo zoom lens for the DVX200 which used a Micro 4/3 sensor, but they never released anything similar as a standalone lens.

    The odd thing, was that Blackmagic actually released a few studio-oriented cameras with Micro 4/3 lens mounts aimed at live productions and such, but ultimately the cameras are severely limited in their usefulness due to a lack of suitable native ENG style zoom lens options. And recently the Pocket Cinema Camera 4K has become fairly popular for live production due to its integration with Blackmagic's ATEM Mini live switchers, and I'd guess that there are some people that would be interested in a decent servo zoom lens option for that camera as well.

    There has been significant growth in live streaming video over the past decade, but for some reason the major Japanese camera manufacturers have mostly ignored this application for their cameras until very recently. For example, there are very few cameras with integrated streaming support for the major streaming platforms (YouTube, Facebook, etc.). And it took a pandemic to prompt them to release software to allow usage of their cameras as a live streaming option through a computer (and they all did so within a matter of months, suggesting that it wasn't all that difficult to develop such a feature).

    Now it seems like every new camera release has features geared toward producing video for internet delivery.
    Yeah, feels like a big missed opportunity.

    At the local news station level, I saw budgets shrink like crazy, and one station moved to smaller camcorders. One of the reasons was that the camera people they were hiring had no experience with cameras before, and the handycams were easier for them, the other was budget. So, as big an opportunity the M43 ENG market could have been....

    ....you know what, I really don't understand it at all, really. Those giant s35 Canon zooms always seemed a little ridiculous to me. made for some front heavy rigs. Saw a couple guys wear out their arms trying to work with those, as they never got the balance right. Which was probably their fault more than the gear, but the Canon's are bigger and heavier than the traditional 2/3" F1.8 zooms. However, as we move into 4K and 8K, I don't see b4 2/3" (prism and all) having many advantages over the M43.

    Seems like all we got was 10bit and raw in 2020. but camera companies are still flopping about, with odd designs and HDMI ports right where the operators hand or ear will be.


    At least image quality is nice this year. Let's hope for better systems and ergonomics some day. Ever since the advent of digital HD, the whole manufacturing industry dove into this super insecure design philosophy of "idk idk idk idk, omg idk!!!". And with every s*%tty design that came out, guess what camera operators did? Yeah, we built a rig that was just like a camera rig that has always worked. Ah well, here's to 2030, when human bodies will evolve into something else, and we'll have to completely redesign camera ergonomics yet AGAIN. [SARCASM]

    Maybe it has some weird modular attachment as in that old GH-4 whatchamacallit.

    MOre likely sidehandle like the current EVA - complete with annoying wobble.

    Yeah, seems odd that the would tie a good servo zoom to an outdated M43 sensor like that, but never have a standalone. Just wild.

    No, it says it's a battery grip attachment. Must be like that old GH-4 YAGH thing.

    I have a theory that if you match depth of field, then you will match size and weight.

    The lauded ENG lenses are around f/2 and 20x. But they are 2/3", whose crop factor is 4.

    The crop factor of 4/3 is 2. So at f/4, its depth of field is the same as 2/3" at f/2. My theory is that a 20x f/4 lens for 4/3 would be about the size and weight of that ENG lens.

    Likewise a 135 lens with a maximum aperture of f/8 would match the depth of field of that ENG lens and likewise would be about the same size and weight for 20x zoom.

    ---

    But people are unwilling to see past the f-stop, even though it has the same depth of field, and so an f/8 20x 135 lens would not sell well.

    ---

    Someone may point out, f/2 will be brighter than f/8. Therefore the 2/3" lens is superior.

    No, because all else being equal, the 135 sensor will be 16x as light sensitive (4 f-stops).

    Going back to 4/3, all else being equal, a 4/3 sensor will be 4x as light sensitive as 2/3" (2 f-stops).

    I would note that an optical adapter with doubler from B4 to MFT turns 2/3" servo zooms into Micro 4/3 zooms with a 2-stop loss. There are 15x & 17x 2/3" zooms that start around a T1.6 or so, so that means roughly a T2.8 & 1/2 with a huge zoom range and wide coverage. Just a thought. Also, there are spped boosters for going both Super-35 to MFT as well as Full Frame 35 to MFT, so there's even more possibilities.
