Not at all, but since you say thata better question is whether you have any evidence for those cameras' AF superiority over recent PDAF-equipped mirrorless competitors from Olympus and Sony? For example, reviews of the Olympus E-M1 are quite favorable about its AF.
m43 do not use PDAF for focusing - only for tracking (E-M1), fast speed of m43 cameras is due to CDAF readouts = 120 measurements per second (first fast CDAF in panasonic GH2), 240 measurements per second (E-M5/GH3 generation sensors) and 480 measurments per second w/ the current generation of sensors ( Panasonic sensor in GH4/E-M1) + optics designed to be move fast by linear motors and respond to such rate of commands flow... I am not sure about the current generation of lenses but prev. generation like Panasonic 35-100/2.8 were capable to work with 240 commands (move forward/stop/move back) per second
PS: just from the recent interview of Panasonic engineers (
http://dc.watch.impress.co.jp/docs/news/interview/20140224_633945.html )
1) about the progress of CDAF speed in Panasonic bodies : 寺坂:フレームレートはボディの進化に応じて増えていまして、シリーズで申しますと
DMC-GH1の時が
60fps、
DMC-GH2の時が
120fps、
DMC-GH3で
240fpsを実現しました ...
while most of other cameras (outside of m43) are still stuck @ 60fps
2) about the related progess with CDAF motors in lenses - the first lens capable to keep up with 240 commands from CDAF system in camera per second (that does not mean that there are 240 commands - that means that lock can be achieved w/ faster in S-AF mode or that when tracking moving object in C-AF you can execute much more focusing moves when necessary or use old-known-first-in-consumer camera depth from defocus CDAF technology in GH4 to achieve closer to PDAF performance using just CDAF) : 井上:いいえ、2012年発売のLUMIX GX VARIO 12-35mm F2.8 ASPH. POWER OIS以降のレンズはすべて240fps対応になっています。
