    hi all,

    ive got a video project coming up and im hoping to use the GF1+20mm. Does anybody have any tips on getting the best quality video out of the GF1?

    sharpness +2? what lenses may be good? the 20mm is very sharp though isn't it. Any post process tips to increase quality?

    I understand the 20mm does not have CAF, which brings around questions of focusing, like what focus distance does f1.7 (which the GF1 is locked to if unhacked) have when focused at infinity?

    And there is obviously the hack!

    Do you lot know of any good videos showing the hacked GF1 high bitrate video samples compared to unhacked footage?

    i can find hacked videos but i want to see how much of an improvement this hack makes.

    Hope you're well and hope you can help! :)

    You should really use the hack. It delivers insanely good material with any good lens.

    Don't use any special settings in the camera. You can always sharpen in post, but this is really not necessary. With the hack the GF/GH1 deliver really good video compared to the cost of the camera.

    And now the manual settings in GF1 bring it to a whole new level. Before it would use too much "gain", as in up the ISO automatically. Now you have total control over your filming :) 

    If you want proof, you can just shoot a video clip with your GF1 and 20mm and then shoot it again with hacked firmware. The whole process should only take 30 mins max.

    So the manual controls are now working with the GF1 hack. :eek: 

    Think I'm going to have to take the plunge.

    Can someone clear up something for me regards CAF and the 20mm panasonic lens please.

    When i use the 20mm on my GF-1 , it does autofocus when shooting video , is this not CAF?

    I would be interested to see a before-after comparison. I have not seen
    one yet.
    The most demanding scenes are wind blowing on the leaves of the trees,
    grass patches, cornfields.

    It is, but it is really slow and chunky compared to the 14-140 (which is video optimized) or even the other Panny zoom lenses, not to mention noisy. Panny does not consider it fast enough to support AFC in regular photography modes, and it is thus disabled.

    Ah , I see now - just had never tried video with my other lenses - they are indeed a lot faster focusing. Cheers.
