    Bill:

     

    You were right: this lense +adapter + body combination works but AF is slow and noisy.

    Case closed – I return lens into the store.

     

    Thank you,

    Alexei

    O.K., now I have the solution from personal-view.com:

    Before converting MTS files into MPG files, I have to concatenate all 4Gb files into one using windows command

     

    copy /b A.mts + B.mts AB.mts

     

    Then AB.mts file has seamless stitch of A.mts and B.mts and can be used for conversion and editing in Adobe Premier.

    Sorry, Bill, I forgot to mention that when I watch MTS or MPG files uising WIndows Media Player, I see video freeze at the very beginning of 2nd and 3rd files (but not 1st!). So, I think this is GH2 and/or card problem. I will experiment with different record modes (say 720p instead of 1080i) but I doubt this will help7,

     

    Thank you for your time,

    Alexei

    Bill:

     

    I understand the difference between file formatting and writing speed; my question was what is more important for solving my problem.

     

    Unfortunately, nothing helps.

     

    I bought Samsung SDXC UHS-1 PRO card (64Gb capacity, 40Mb/s writing speed) and shot 1.5h long clip (no stops – this is my only success). I created 4 MTS files 4.18Gb each and converted them into MPG files using AUNSOFT MTS converter7 Then I imported them into Adobe Premier Pro CS4 and stiched all these files. Finally I created one mpeg2 file.THe result is: at each stich between two files video freezes for 0.5s while audio seems to be smooth.

     

    Any other recommendations before I give up GH2?

     

    Thank you,  Alexei

    Bill:

     

    I noticed that these cards use ExFAT formatting, not FTA32. Is this parameter is more important than high writing speed (say, >25MB/s)?

    HI, Bill:

     

    Thank you for comprehensive reply.

     

    It looks like my problems are due to insufficient card speed. I use Lexar platunum II  x100 class 10:

    http://www.bhphotovideo.com/c/product/801553-REG/Lexar_LSD16GBSBNA100_16GB_Platinum_II_100x.html

    that is rated 30 Gb/s but only only 9 Gb/s write speed (unfortunately I noticed this difference only now).

     

    I'm advanced amater, going to use GH3 for long (~1h) shots with mamximum quality that GH3  can deliver (I know that it allows for higher bitrate than GH2). What will be your MINIMUM recommendations for SDCH card? – what you recommend above seems too expensive for me.

     

    Thank you,

    Alexei
