Tilt/Shift on the GH4

Metabones recently introduced, Canon EF Lens to Micro Four Thirds T Speed Booster XL 0.64x. Andrew Reid of EOSHD has an interesting article here Panasonic G7 and Metabones Speed Booster XL hands-on - Super 35mm 4K for cheaper - EOSHD.
My question is will a Canon 17mm TS lens work on the GH4 with the Metabones? If yes than would one expect a field of view of about 11mm, normal tilt and shift function and maximum aperture of 2.8?
I have been doing real estate photography with the GH4 using the Lumix 7-14. My results are quite good but always looking for a better mouse trap.
Comments and opinions please.

Re: Tilt/Shift on the GH4

If the Canon lens is 17mm, you multiply that by 2 (the crop factor of the GH4), then you multiply that by 0.64 --> 21.76mm. That's how it works to the best of my knowledge.

Re: Tilt/Shift on the GH4

I think the crop factor in 4K movie mode is actually 2.3x so 17x2.3=39.1x0.64=25.024mm
So essentially you would end up with an angle of view similar to a 25mm lens on a 35mm camera.
Your 7-14mm lens starts at a 16.1mm equivalent so much wider, & probably for your interior shots, much better.

Re: Tilt/Shift on the GH4

Thanks for contributing. I am shooting stills. I am considering a tilt shift lens to remove distortion and get a wider field of view via the panorama feature afforded by the shift feature of a T/S lens.

Enjoy
