I Can't Use My Sigma 18-35mm Art

My Sigma 18-35 MM is unusable with my Viltrox EF-M2 II because the iris is not available on my BMPCC 4K.

Those bmpcc are funny we have two same lens on both at times on power up on will show the the iris settings one won't. You have to have it set to auto I think before un turn on the cam

I'm not an expert so forgive me for asking but why would you use a speedbooster rather than a simple auto focus adapter with this lens? I don't understand what it is you were hoping to accomplish.

[@JJMcgechan]

Because the sensor on the camera is smaller

[@marcopervo]

It works great with the Metabones x .71 Cine BMPCC 4K Speed Booster. Getting full coverage using only three Sigma Art lenses makes the Metabones worth the extra $$$.

[@topshelf223]

Which three?

[@riccardo.vitale.videomaker]

have same setup, viltrox, 18-35, pocket 4k and it work

[@MapleOrange]

i actually ended up upgrading to the 6k pro

[@CARTEBLANCHE_MV]

bro! i have the lens, speedbooster and the camera.
the way to solve it is bij changing the speedbooster firmware to a older version.

[@MapleOrange]

Oh really?? I will look into it

[@CARTEBLANCHE_MV]

@@MapleOrange yeah man , just try find the right on for you.
Minder! Do not keep the speed booster on your camera when updating !!

I have the same issue with mine. It's super frustrating. And I don't want to pay 600 for a metabones for this one lens either lol.

[@MapleOrange]

[@MapleOrange]
