Sigma 18-35mm f/1.8
I'm thinking of buying a Sigma 18-35mm constant f/1.8 with a Sony A mount for my FS700.
The reviews have been generally good... But today I was wondering, if I were to get the Canon mount... would it work with a Medabones Speed Booster? Would it become a F.8 lens and 0.71x wider? Would it vignette, if so at what mm? Sigma 18-35mm F1.8 Lens Review ? DSLR Video Shooter Bill Kerrigan Montreal, Quebec, Canada |

Re: Sigma 18-35mm f/1.8
From what I've read about the lens, it is designed for APS-C cameras. Therefore, if you used the Speed Booster, you'd most certainly get some vignetting.
The Speed Booster is only designed to be used with full frame lenses, and APS-C is not full frame. Actually, APS-C is very close to the Super35 sensor size of the FS700. I've used APS-C lenses on my FS700 with the non-SB Metabones with very little vignetting issues, so I would gather that you could probably use this lens just fine with a non-Speed Booster adapter. |

Re: Sigma 18-35mm f/1.8
Are you sure its even available in A mount? All I find so far is Canon and Nikon mounts.

Re: Sigma 18-35mm f/1.8
I confirmed with Sigma today that there is no a mount version of this lens, although they did say that they had a lot of requests for an A mount version so one will be announced in December.
