GH3 Wich Speedbooster for GH3 using Nikkon DX lenses?

[Xoomtell]

Hi

Any one who knows if I can use my Nikon DX (G and D) lenses with my GH3 with the Metabones Speedbooster XL 0.64 or should I go for another - like the ULTRA or some of the older ones?

I have quite a few DX lenses, that I use with my Nikon D7100 (like the Tokina 11-16 2.8 and the AF-S Nikkor 35 mm 1.8) and wich I have also used from time to time on my GH3, using a cheap MTF converter. But it´s not a very good solution bacuase of the crop factor. Therefore I have considered investing in a Speedbooster, but I´m concerned about vignetting and how it will crop when using a DX lens? I have aslo considered buying both a Speedbooster and the Sigma 18-35 mm 1.8 and use that lens as the primary lens for the GH3. The D7100 can use both fullframe and DX format, so I will be able to use the DX lenses for both the GH3 and the Nikon...

Any suggestions or thoughts?

thx in advance!

DX lenses are more likely to vignette with the XL Speed Booster when shooting 1080. The XL is designed for the GH4's 4K mode, which uses a smaller portion of the sensor. The standard or Ultra Speed Boosters are what you would want if shooting primarily in HD. I have not compared the differences myself, but the Ultra uses updated optics which are supposed to provide better image quality than the original Speed Booster.
