The need for fast video lenses: Cosmicar/Canon/Tokina 12.5-75mm f/1.8
This is the only GH1 + 12.5-75mm lens I found on vimeo 
We have still to wait a little bit before to get our GH2. To kill the time I searched for some exotic fast zoom lenses that we (and I) might could use on the GH2. There is one particular interesting lens I found on eBay (Click here). The Cosmicar-Canon-Tokina 12.5-75mm f/1.8 C-mount lens! The focal lenght and constant fast aperture is very interesting and but sadly I found only one video taken with the GH1. The Karaoke part is terrible
A few pictures can be seen at Flickr. The japanese website geocities.jp tested the Canon version of the 12.5-75mm lens.
That lens is deifnitely not a professional solution but we have to wait a few months before Panaosnic releases the already announced fast wide and normal zooms!

2 years ago |Panasonic Fast zoom will be certainly interesting BUT I don’t think they will be as fast as C-mount zoom could be (up to 1:1.0 !!!). When you see on the market that fast 24/36 zoom such as the very good Tokina 11-16 f/2.8, I don’t think that the upcoming Panasonic will be much faster than it. The new 1:1 option on the GH2 will be great to avoid vignetting on these C-mount zooms. The test from Andrew is giving good result, much better than the digital zoom of the GH1.
I’ve done a movie test with a 17-102 f2:0, very closed to the Cosmicar C-mount zoom here, with no digital crop :

In VIDEO – the crop for u43 IS NOT 2x, but closer to 1.8x.

Great poll!
But you have to make a PETITE FINALE with more detailed variable lens specifications!
Who is the real winner in the super zoom standard category?
1. 23%: 12-75 mm
if you add the voters for the 12-75mm f/2.8 and
the compact version 12-75 mm f/2.8-4.5.
2. 17%: 12-50mm f/2.0 OIS video optimized with the current specifications
and without price indication.
3. 16 %: 12-60mm f/2.8-4.0 if you believe that the current Zuiko owners will
buy the same version for micro four thirds instead of using the old one
with an adapter.
Currently Olympus and Panasonic fans are mixed up and lost in insecurity!
In my opinion one of the main reasons is OIS!
For example:
I want a video optimized 12-75mm f/2.8 zoom – but without OIS because I`m an Olympus user/fan. Instead I would prefer the 12-75mm f/2.8 with Olympus quality of the Zuiko 12-60mm /f2.8-4.0 (optical quality, handling, SWS, autofocus speed and with the same weather sealing together with a professional micro four thirds camera also video optimized, Full-HD AVCHD).
But I was forced to do a strategic vote in your poll voting for Panasonic: I had to choose the 12-75mm/f.2.8 with OIS to avoid getting a slow compact Olympus version lens 12-75mm f/2.8-4.5.
So in this case Olympus and Panasonic get wrong information about my real needs.
A second reason for a petite finale is the lacking of prices of the different lens specifications.
There is also a need for price information of the very interesting 12-50 mm f/2.0 ($ 1.200, § 1.500 or §2.200) to prepare an ultimate success for the new professional standard wide zoom in real life.
Petite finale:
1. Are you an Olympus fan/user (having IBIS-
In House Body Image Stabilization)?
2. Are you a Panasonic fan/user (need OIS–
Optical Image Stabilization)?
3. Don ‘t know – like Olympus and Panasonic either
For example:
12-75mm f/ ?? standard version (opt for your optimal specifications you are willing to pay for!)
4. Do you want weather sealing (additional $ 200)?
5. Do you want a video optimized zoom (additional § 400)?
6. Do you want a very fast professional standard wide zoom ( additional $ 600)?
7. Can it be slow if it is compact and lightweight?
Very important: ask the product specialist of Olympus and Panasonic about the physically possible lens specifications and a real pricing due to production cost before you make the second poll (petite finale).
Best regards

2 years ago |i think all the 12-50, 12-60, 12-75 should have been lumped up in two (fast & slow) categories. OIS or not goes without saying that if Panasonic they’ll have it.
The most important thing is that 14mm is becoming a super-boring focal length in 4/3 & m4/3!!! The standard zooms that start @ 14mm (28mm-equv.) greatly outnumber those that start @ anything wider like 13 or 12mm (26 or 24mm-equv.), this is in contrast to what you can have in APS-C systems, where standard zooms can be 18mm, 17mm, 16mm or even 15mm (27mm down to as wide as 24mm eq.) @ their wide end.
