If you expose for blown out highlights, push shadows, clean with neat video, you can capture just as much dynamic range from the GH3 as you can from Magic Lantern RAW.

this came out very very clean how far are you pushing the shadows and under what settings? natural normal -5's ? I use a GH3 im honestly trying to become more fluid in my CC but im such a minimalist for certain things I do. Shorts id love to stop things down and become better at CC.

Hi Andrew Im sure youve been asked before but is there any Vignette for the 18-35mm lens on the slightly less crop factor for the GH3? Ive once again been delayed on my pana leica 1.2 42.5mm so the possible time frame for a full electronic metabones + sigma combo feels likely again for me.

"It makes no sense at all to me that your Sigma lens could vignette for video."

 

Well all I can tell you is that is does. I was shooting in standard 16:9 on a Panasonic G6 (Did the same on a GH3). No hood, not even a UV filter. As I said even wide open there is some shading in the corners, stills and video. I don't have any other DX lenses to compare, as everything else I'm using are 35mm lenses so I can't tell if its just this lens (this example or the model in general.) No problems with any other lens. Basically I really don't have any answers for you.

 

Personally, its not a problem, I was selling the lens anyway, have now sold it. However I thought that I should post what happens with the lens. By the way its almost brand new and hardly used. I bought it for some low light work, but with the Speed Booster I don't need it now and I have better lenses anyway.

 

Apart from that, and presuming that you are Brian Caldwell ???, my congratulations on a spectacular piece of kit. The results I'm getting for stills and video are just incredible and your 'magic' (though I do realise it has nothing to do with that!) trick of widening the lens, adding a stop more light and actually improving my lens performance is seriously impressive. I'm using nothing else but my Nikon primes currently and have a Nikon > Fuji X Speed Booster on order, to use them on that camera. So I'll leave the Sigma mystery with you (Perhaps some other users might clarify whether its a problem with my lens or more widespread.)

 

Anyway thanks for replying and above all thanks for your creation. Best piece of kit I've bought for years.

I was hoping you could post some links so we could observe for ourselves the vignetting from using the Sigma 18-35mm with metabones attached to the GH3/G6 it would be much appreciated,

Can anyone tell me if the Metabones EF to m43 will have electronic connectors aswell? also aside from that will the Metabones work with crop lenses from EF to m43 or will only FF lenses work

Thanks
