GH4 with 45-175 Power lens and Manfrotto remote

Categories: GH5 camera, Lenses 10 Comments


Taking the Lumix GH cameras to the next level Panasonic have opened up the camera with the ability to use a lanc remote to control one of two power zooms.


In the custom menu 7/9 you will find the POWER ZOOM LENS button which takes you to menu A where you can choose various zoom modes including zoom speed (menu B) the choice between Photo and Video is interesting but choosing Video (menu C) allows you to choose High, Medium and Low speeds but remember whatever you choose you still get a level of control over your zoom it is only limited by the top speed i.e. H,M,L.


I had the Manfrotto MVR 901-ECPL for my Panasonic PX270 and works a treat with the GH4, you get variable speed up to the limit you set and REC on and off.


Once again I can’t stress the need for a good set of tripod legs and capable head like the Manfrotto 505 HD.


As you can see the lens is very small and is an internal focus so the front element does not move. Here are two shots taken with the Lumix 45-175 f4-5.6

175 45mm

It’s a major bonus to have a servo zoom facility on a camera like the GH4 the only restriction being the maximum aperture set at f4 and the 4x zoom ratio, this does not compare with my PX270 at f1.6-3.2 with a huge 22x servo zoom.

Maybe this will promote Fujinon to produce a micro 4/3 power zoom 14x lens starting a f1.6 !

    I can’t imagine how large and heavy a lens with those specifications would be.

  2. What happens with the iris when zooming? – Does the camera (smoothly) adjust as the focal length changes or does the picture go darker/lighter?

    HDW : I think the f4-5.6 is a give-away this is not a constant aperture lens, you will only see the effects of the lens getting darker in lower light.

      The maximum aperture of this lens varies according to focal length.
      If you set the lens to f4 (maximum aperture) at 45mm then zoom in to 175mm the lens will step through it’s range of maximum apertures during the zoom (you can watch the aperture values change on the display: f4, 4.1, 4.2, 4.3, 4.5, 4.7, 4.8, 5.0, 5.3, 5.4, 5.5 and finally reaching f5.6 at approximately 169mm).
      As expected, these steps (not a smooth progression) will be recorded on the video when shooting using Aperture Priority (with fixed, not ‘Auto’, ISO) or Manual exposure.
      If you select f5.6 or higher (by deliberately selecting f5.6 or higher at 45mm or any other focal length including 175mm) then the lens will hold the chosen aperture throughout the zoom range.

      By close examination of still images (which will have the same pixel-for-pixel resolution as the GH4s 4K/C4K and EX-Teleconverter modes) lens performance (of my lens example) looks something like this:

      45mm – soft with obvious corner falloff (vignetting) wide open (@f4) – sharpest at f5.6
      100mm – slightly soft wide open (@f5.3) – sharpest at f5.6-f8
      175mm – good wide open (@f5.6) – sharpest at f8

      Optimum aperture throughout the range is in the f5.6 to f8 region.
      At all focal lengths the image gets noticeably softer due to diffraction at f11 and higher apertures. This may not be a problem when shooting down-sampled 1080p/720p using the full sensor area but will be apparent in 4K/C4K and Ex-Teleconverter mode videos which use the native pixel-for pixel resolution of the sensor.
      Close examination (zooming in manual focus mode with 10x image magnification on the display and peaking enabled) shows that my example of this lens appears to be parfocal. Other examples may not be (I have two identical Nikon 50-300mm f4.5ED lenses of which one appears to be ~parfocal but the other clearly shifts its focus on zooming).

    pick up my GH4 today(already own GH3, 12-35 and 35-100 lenses), feels like a rerun of the excitement when the Canon mk 2 arrived on the scene and changed everything! Very pleased I stumbled onto your website and look foward to visiting on a regular basis!

    Can you get a “crawl” speed with the Manfrotto MVR 901-ECPL? or is it limited to the three programmed zoom speed in camera.

    I would also like to know ? Can you get a “crawl” speed with the Manfrotto MVR 901-ECPL? or is it limited to the three programmed zoom speed in camera.

  6. davedv says:

    The zoom speed is always variable (using the zoom rocker on the zoom controller). The in-camera setting just seems to affect the maximum zoom speed you can achieve.

  7. Hi, I know I’m asking a lot by stepping in on your site, but I have the G6.

    I’ve been searching around for confirmation that the Manfrotto wired remotes will work with my G6. I’ve seen a Youtube vid showing that an Ibec works with the GH4, but the G6 only has reviews on the camera.

    Can you help me?
    Which Manfrotto remotes are likely to work (zoom and record) with my Lumix G6 and 14-42mm PZ lens?

    Thanks in advance, Leslie

    HDW : The Manfrotto MVR-901 should work with your camera as long as your remote socket is 2.5mm.

    Hi, can you tell me if the Manfrotto MVR 901-ECPL also works with regular Lumix lenses? At least the Start/Stop function?

    I have been trying to get it to work with my GH3 and the 12-35mm Lumix lens but didn’t suceed.
