I just posted a sample in 'lenses', where the Laowa 7.5mm does double duty as a 10.5mm. Jon, could you help me with the math? So, let's say I have 28mm lens. Then I use a metabones .64x speed booster. That lens is now a 17.92mm, lets round up to 18mm. Then I double for the GH5 crop, and it's 35mm equiv is 36mm. Then with ETC, it is 36x1.4=50. So the 35mm equiv of a 28mm lens on a GH5 with .64x speed booster with ETC enabled is roughly 50mm. Is my math correct? Quote Link to comment Share on other sites More sharing options...

There's also a 2.7x crop in HD, but supposedly it's not as clean, and I haven't shot in HD with the GH5 yet. Quote Link to comment Share on other sites More sharing options...

I was pressed for time so I didn't get to do an A/B but here is a shot with the DDFX 2 on the Sigma Cine 50-100. Jonesy Jones 1 Quote Link to comment Share on other sites More sharing options...

Marcel Zyskind Posted September 20, 2017 Share Posted September 20, 2017 I tend to use Tiffen White promist and Schneider Black Frost. The latter a lot more. On 35mm white promist is beautiful. Always 1/8. Any more than that and it can get too noticeable for my taste. Quote Link to comment Share on other sites More sharing options...
