Emulate full frame look with speedbooster or 17.5mm lense + anamorphic adapter?

I just bought a Panasonic GH4 and trying to decide what to buy to emulate/look close to a full frame 35mm. A read a lot about the Metabones Speedbooster which seems to be a popular choice but I'm trying to see if there's an alternative... Would I be able to get a full-frame look using Voigtländer 17.5mm which is a 35mm equivalent on the GH4, as well as an anamorphic adapter like the SLR Magic Anamorphot?


There is no such speed booster.
A speed booster makes a MFT sensor look close to a cropped sensor not a full frame sensor.

Ultra multiplies by 0.71 while XL multiplies by 0.64.

I am relatively new to this. I meant come close to a full frame look.

Anamorphic and Full Frame (spherical) are two different beasts (oval bokeh vs. round bokeh). I have three Voigtländer f0.95 lenses (17.5, 25, 42.5) and a GH4. When wide open they are not exactly soft, but they have lower contrast than at f1.4 (or f2). After f2, their look doesn't change much, except for more and more depth of field. As for comparing with FF35, the 17.5mm at f0.95 has the same depth of field as a 35mm at f2, but the former has much less contrast than, say, a 35mm f1.4L stopped down to f2. The 17.5 stopped down to f2 has really good contrast, but the same depth of field as a 35mm at f4, which is definitely different than shooting Canon's latest 35mm f1.4L II at f1.4.

On the other hand, the GH4 still brings exceptional video capabilities to the table. And the Voightländer lenses are pretty nice, too. Rather than trying to emulate 35mm, focus on getting the most out of your m43 system and you'll get great results. The problem with trying to emulate a different system is that more often than not you'll imagine the other system having capabilities it does not in fact have, and you will constantly dissatisfy yourself missing targets that the other system itself also cannot hit.

BTW, here's an example of racking focus using a 25mm f0.95 lens on a Panasonic AF100:

That shot is rad.
