GH2 Which GH2 should I buy?

Just recalled the lenses I have that I posted here. I'm very sure I won't have any issues with the aperture on my Super Takumar lens since it's a manual lens. However, what can I do with my other lenses that aren't manual?

Canon EOS lenses are a problem because of the electronic aperture.

That's why a lot of GH2 users opt for the Nikon versions of modern lenses (such as the iconic Tamron 17-50 2.8), since the Nikon's aperture can be adjusted with a physical lever on the adapter (its mechanical as opposed to electronic like EOS mount).

That being said, I also own many Canon lenses and not willing to purchase new ones, especially since I also use the Canon for photos.
So, thankfully you do have a couple of options:

1) An adapter with its own iris. These tend to get pricey, and the quality varies widely between them, but basically you get manually controllable iris blades built into the adapter, which stop down your aperture behind the lens. The problem is, sometimes the bokeh isn't as nice as the real aperture blades, and it can also cause vignetting since it is operating outside the lens body and less controlled.

2) Use a Canon body to set the aperture. This is what I do, since its free and works. Hey, the reason I have Canon lenses in the first place is because I happen to have a Canon body available to me, so I carry around in my gear bag for just such an occasion. Basically, put the lens on the Canon body in M or Ap mode, set aperture and press the DOF button on front. Remove lens while continuing to hold down the button, and voila! Your lens is now locked to that aperture until you put it back on the Canon body!
The problem with this is that you can't change the aperture easily during a shoot. You have to remove the lens, put it back on the Canon body and repeat for each change. But in a carefully controlled environment, you shouldn't need to change aperture much anyhow. I have been using this method a lot for my Tamron.

3) I think there are rumored adapters in the works that will actually electronically control the aperture of an EOS lens (I think powered by its own battery, the adapter simulates signals from a Canon body using a digital remote control). This is probably going to be very expensive though. I'm sticking with option #2 for now.

Ok. That's what I do too when I do macro photography using reverse lens technique. I forgot about it. Glad you mentioned about Nikon. I should look into it.

About the adapter that have an aperture blade, I saw a video and I didn't like the quality.

Thanks a lot!!!
