Question about gh3/4

The speedbooster is one of the only adapters that can adjust the aperture for ef lenses although it costs like $600. It makes you lenses 0.71x wider and increases the aperture by 1 stop so it increases the max aperture of all you lenses. The extra width would somewhat be compensated due to the fact that the gh3 and gh4 have a tighter crop factor especially with the gh4 in 4k mode The only lens that I would expect to vignette would be the 8mm fish eye. Trying to adjust the iso and shuterspeed would not be very good alternatives as you would be stuck with whatever you max aperture is. This would make follow cam shots that are normally f8+ challenging and out of focus. The gh3 and gh4 both have better low light performance than the t2i especially the gh4 in 4k. Whether or not adapting you lenses or switching to Nikon is up to you. It may be helpful in the future as Nikon can be adapted to almost any mount if you can sell you lenses for a decent amount.

you're buying the wrong adapter lol. novoflex and metabones both make a g adapter(for nikons) or an adapter that lets you change aperture

Thanks!! what about using NDs instead of messing with the ISO+shutter.

so youre sayin I should switch to Nikon?? do they make one for canon? just at work and everything is blocked.

actually... i have no idea how canon mounts work sorry.

But they do make an electronic one for 400 I think

Nd filters won't change the depth of field.

You can get a metabones adapter for canon ef that can control the aperture electronically, but it costs $400 for the "smart adapter" which can control the aperture or $600 for the speed booster version.

Switching over a set of Nikon mount lenses is definitely a good call if you can afford it. That way you have a set of lenses that can be easily adapted to pretty much any camera. If you decide you want to upgrade to or rent or borrow a different camera, you'll have no problem using your lenses on it with a cheap and simple adapter.

I would suggest you sell all your Canon glass and get F mount versions of:
Tokina 11-16 2.8
Sigma 18-35 1.8
Any vintage F Mount 50mm
Nikon 75-150 f3.5

For less than $1500 you're covered from Ultra Wide to Tele with quality glass and decent speed.

As for using ND's, you should really always be using ND to control exposure when shooting video. Shutter speed should always be as close to the 180 degree rule as possible, you don't want to be forced to use a less than optimal ISO setting, and you want to be able to use aperture to control depth of field without fucking your exposure.
