There is no official GH2 firmware 1.1, it is still 1.0 ...

@JDN,
Thank you, I will have to think about your suggestions as Nokton is not so cheap (my dream lens) ....
@woody123
The firmware on my 20mm 1.7 is 1.1 but still feels slow (not as fast as 14-45 mm) ...

I will be buying a wide-angle converter x .7 in order to get it act as 14mm and have read
that in some cases helps with auto focus, it gets faster ...
The adapter I'm considering:
Digital King DSW Pro 0.7x Wide Angle Lens 52mm at Amazon got top reviews and it weights only 65g,
not much pressure on focusing barrel to 20mm 1.7, I think.

PL 25. AF. No OIS. $599. Nokton 25mm at $1199.

The 14mm is cheap (B&H online) and versatile (ETC turns it into a near 50 mm which is handy). Personally been very happy with it (I shoot B/C-cam / casting in TV) . The aperture difference (2.5 versus 4) is significant depending on what you shoot -- f2.5 will allow you to shoot at sunset at iso 160 and night at higher but still useable isos (same goes for indoors), while you can't get into pretty risky iso territory with f4. AF is fast, and more importantly if you're shooting with any onboard mic, silent.

If you have time to compose your shots, looking towards drama as opposed to doc, yes, save up for the voiglander -- it is beautiful. If you like that look, but would use it only rarely, by a 50mm f1.4 cannon lens on ebay for $100 and an adaptor and be happy with that. For doc or just a lot of run and gun, AF is really a gift (and gives you a nice bit of security -- with shallow depth of field, you do have to put in a bit of time with every shot (eg pushing in the click wheel, turning past focus then back into focus) to make sure you are truly in focus -- you can get caught as the lcd of the gh2 is simply not up to par compared to other gh2 -- it's one big failing compared to other competitors IMO).

Depending on your needs and style you may also want to consider the 7-14mm -- I vetoed it because I couldn't stick a uv filter on it, and since I shoot in sandy, wet and grimy locations, not having protection was a deal breaker. That said, once you get much beyond 14 mm in m43s you start to get some distortion in a lot of settings, which is unoticeable in stills but distracting in video.

Anyway, for what it's worth, there my two cents. Hope it's helpful.

@Mimirsam
Thank you,
no i do not need more zoom at present time, for zoom may be later 100 - 300 mm would be great ...

Than is better to save the money and buy Voigtländer 25mm 0.95 for "controlled" footage , actions ...

@Mimirsan
Thank you.

I'm thinking is it worth buying this or not ...
As I own also kit lens 14-42 it has OIS (optical stabilizer) the only benefit i see on aperture ...
So if I use it with hand stabilizer (i mean running, walking with steady cam etc ...), there is no OIS on 14mm pancake ...
The 20mm i cant use cause of slow focus , action scenes requires a fast auto focus when running with steady cam , at same time 20mm is great for night shooting ...
Should I forget 14mm pancake and save money for 14-140 HD version video optimized ?

AF is great on the 14mm...I use it more than the 20mm for out and about shooting ;-)
Less DOF
