    Default My First Impressions Review on Panasonic GX7

    Panasonic GX7




    Introduction
    When I started to do review for Panasonic GX7, I have problem to get the settings correct. I encountered banding issue under fluorescent light and unable to set it to take longer exposure ( > 1sec ). I have hard time to find the solution online and in the manual untill I accidentally disable the slient mode (Electronic Shutter). So for all GX7 users, you must know how to set this option. It is located in the menu > Custom > Slient mode. Turn it on if you want to take photo in stealth mode else it solves the banding issue under fluorescent light and able to take longer exposure during at night.

    Body and Controls
    The camera is made of magnesium-alloy with rubber-coated grip which feels solid and provide good hold. The front and mode dials are stiff enough that that respond well when turned. The power switch is in good position for fast access.

    Top View


    Back View



    Electronic Viewfinder
    The unique feature about this camera is it has a flip-up electronic viewfinder which allows low level angle photography. It is built around a 1024 x 768-pixel LCD panel which is similarly high-res LCD used in the Olympus VF-4 viewfinder.


    Wi-Fi
    The Wifi feature is useful as it uses NFC to establish a connection and transfer photos wirelessly simply by 'tapping' the two devices together. You can also use smartphones with IOS or Android app which able to take remote control over almost all the camera's settings and take photos.

    Burst Speed Test
    My first review test is the burst speed test. I am very impressed with the Super High burst speed mode which it can take up to 40 frames per second however in lower resolution format of 2272 x 1704. This high speed mode is useful for high speed action photography. See some sample of speed high burst mode in 800x600 animated GIF format (Click on the photo below).

    Boy Kicking Ball - 16 frames




    Grey Heron Flying - 12 frames




    Girl Blowing Bubbles - 14 frames




    Landing Dragonfly 1 - 20 frames



    Landing Dragonfly 2 - 22 frames

    Timelapse Test

    This feature is pretty easy to use if you are a regular timelapse shooter. First, set your GX7 exposure settings and focusing set to manual. Then go into Menu > Timelapse mode and set the interval (e.g. 1 sec) and counter (number of photos). E.g. if you want to create a 10sec timelapse video, you need 10 x 30 = 300 photos. Set Interval = 1 sec , Counter = 300. Press start to begin the timelapse and the actual time taken will be 300 / 60 = 5 minutes. The results are all in jpg files and use any popular video application to convert them into the video.

    See sample below

    Panasonic GX7 vs Olympus OMD ISO Test

    Below shows a photo of simple studio of my kid toys for ISO test. Both cameras were tested using the same lens, 20mm f1.7 @ f16 and mounted on the tripod. See the red left rectangle selection ("DUTCH LADY" wording) for 1:1 cropping comparison.


    20mm f.17
    f/16, Shutter Speed various depend on ISO values
    Mode: Av
    2sec Timer Mode


    1:1 Cropping




    Results
    The above results show that Panasonic GX7 has slighly lower contrast and comparable noise level to Olympus OMD.
