except you you're missing the main problem- getting a wide FOV - 14mm would get up up to - around 70mm on the ex tele. fail.

The childish language is unnecessary, this is not a pissing contest. A forum purpose is to collaborate and exchange ideas. I'm not sure why would anyone use the Panasonic 14mm with the crop mode to get a wide coverage. Maybe you missed the part were I alluded at not being limited to ISO 800 due to the larger noise pattern using the Panasonic native lens?

sorry didn't mean to offend.. it's my twisted kind of humor. apologies.
the idea was how to benefit from the natural sensor read of the ex-tele mode (which suppose to be even better than the normal mode), and still maintain a level of wide FOV..
and realizing that even 10mm lens won't solve the issue.

+1 the 14mm F2.5 is a great wide angle option. However, the 7-14mm will be the best m4/3s wide angle option. Most people don't realize that the 7-14mm is one of the sharpest lenses you can buy. That is why it costs $1000.
Well seeing as I don't have a GH2 yet and probably won't until January, I won't be able to. The whole point of these discussions is to put ideas forward. You seem to be looking for something more than you've already been given. If the tele crop works the way expected, it will be a bonus in some situations. You can't expect a tele extension feature to give you perfect super wide angle coverage too, that's a bit of an oxymoron right there isn't it?
The Switar combo might give reasonably wide coverage, but until someone here puts the 2 together ( and someone will ) it's just speculation.

If you want wide, just get the Lumix 7-14. Forget the extended crop, you'll get 7mm from the full sensor. It's massively wide.

thanks Barry.
30-40mm wide is enough for me (that's why i invest in a canon fd 20mm- for my fd set).
this whole debate is just because i understood (by eoshd) that the crop mode is better than the normal mode. so i started investigating on vintage options to take advantage of that.
(but from my testings with the canon's - the crop mode was softer and didn't look better than normal mode- but i suppose the FD's not helping here)
apart from that i'm happy with my "narrative" FD set.

"better"? Better is always a relative term. If all you wanted was a sharp 1/2" camera with deep depth of field, you could have had that at any time over the last 30 years...
The whole point of the Gh1/gh2 for filmmakers is the shallow DOF. You lose that with the extended crop mode. So is it "better"? It'll maybe be sharper, depending on how they do the extraction and the scaling, and it should eliminate all the aliasing (depending, again, on how they do that). So in those ways it will be better, but it will mean giving up the shallow DOF. So "better" isn't an absolute; it will be "better" for some things, and not for others. As you've already discovered, it will be nigh unto impossible to get any sort of wide angle at all, so if you need wide shots, it's definitely not better for that. On the other hand, if you need extreme telephoto, yes it will be ideal for that.
There is no absolute "better". It's just another tool in the arsenal. And a welcome one.
I agree 1000%. The concepts of "benefit", "good", "better", and "best" are always in the eye of the beholder and almost always specific to a purpose. OK... Politically Correct BS Mode = OFF!
When I saw ETC, I wanted to do handsprings. (Given my knees and other joints, that would be an interesting spectacle!) Lots of people want to use it as a super-long tele. And that includes me. I'll have to check it out when I get my GH2, but one of the things I want to try using as a "quick zoom". For example...
My wife is testing for her First Kyu in Aikido in February and I want the GH2 to shoot here test. Martial arts testing is interesting because it typically involves lots of movement. Which typically means wider shots. But sometimes the facial expressions are great! I think it would be excellent to switch on ETC mode (maybe using one of the programmable function buttons) to get a quick closeup up her face or head and shoulders for a second, or then to switch back to standard mode. I sincerely hope that's feasible because you could quickly capture some great closeups in the midst of your wide shots.
Now if B&H would only get the things in stock!

Not shabby at all. In terms of 14-140 kit lens which is 10x that's 55x zoom! And he still can follow the birds (even though shooting off tripod) with the jello being quite acceptable. Or is it the water ripple that masks the RS wobble?
Cause here it is much more apparent:
And this one is just a... errhhh... just a freaking telescope!

Early reviews that I've been reading suggest the GH2 doesn't have much of an aliasing/moire problem anyway. That's what has me so excited for this camera (that and the raw HDMI out with no overlays).

i know that.. i meant better just picture-production wise..
Theoretically, it should still be possible to maintain reasonably shallow DOF given a "fast" lens. For example, if one used ETC mode in 1080 mode (2.6x) with 20mm pancake wide open, the DOF and FOV would be equivalent to that of a 52mm/f4.5 lens. About the same what one would get from 14-140 (in the shallow DOF department). It is only when one gets to ultra fast glass like Voigtlander 25/F0.95 when one gets "resonably shallow" 65/2.5 performance.
So yes, it is another tool in box and by no means a universal one. But Kurosawa would be elated ...
Indeed, you get to have your cake (extra light from larger aperture) and eat it too (wider DOF)
One question I have wondered about is whether with extra teleconversion function, the rolling shutter effect will be less of a problem or the same? What I mean by this is whether the read out from the sensor is faster because it is only using the central portion. My only reason for asking this is one of the main reasons I will be getting a GH2 is for some macro work and long lens stuff, both of which obviously exaggerate the jello effect. It just occurred to me that it might be different in the cropped mode. So I'd be interested to hear anyone's experiences when they get to try out their GH2's as to if they find the extra teleconversion function improves the rolling shutter effect or doesn't make any difference. I appreciate that if you simply use this feature at the same focal length, that the movement would be exaggerated because you have narrowed down the field of view, essentially giving yourself a longer lens. So I mean at roughly the same angle of view.
I am interested on seeing the affects of teleconversion on jello as well. Apparently the G2 has that same feature already though. I would love to see some samples from the G2.

A nice demo of the GH2's ETC mode by "TKYSSTD" (really good tripod work, too):
