GH2 & 14-45mm..good enough?

Yes, so long as you are reasonably close to your subject. You can always buy other lenses later

 

Never had a 14-45 but you may get focus motor noise in your videos. The 14-140 has a different silent motor.

 

14-140 is the way to go

For video, the 14-140 is really "the" lens to have. It offers continuous AF and the motors are virtually silent. The 14-45 is "OK" but you won't be able to enjoy the GH's video quality and performance w/o it. Eventually you will get the 14-140, so it might be worth waiting and getting it as a package where it is less expensive.

 

Totally agree with Wasabi

 

I have the GH2 and both the 14-45mm and 14-140mm. For stills I prefer the 14-45mm: its IQ is at least as good as that of the 14-140mm and it's much lighter. Especially when using the 14-140mm above 50mm the IQ degrades, especially in the corners and it's no match for the 45-200mm, so I don't see the point of using the 14-140mm for stills despite its obvious convenience of not having to switch between lenses. Also the 14-140mm's highlights tend to bleed into darker areas causing highlights to look somewhat unsharp.

BTW, I'm on my 2nd sample of the 14-140mm, both behave similarly. Will I keep mine? Yes, for video. Won't say anything about that, because I'm totally ignorant about video
