Hi,
There is a good explanation of the speed boosters at the Metabones site.
https://www.metabones.com/assets/a/s...te%20Paper.pdf
Theorically, a speed booster is a focal reducer which allows to "concentrate" the light provided by a lens on a smaller surface, and therefore obtain a brightness gain.
Typically,
FF lens + speedbooster = usable with S35 sensor
S35 lens + speedbooster = usable with one inch sensor
So theorically it should be possible to use the FX6 in S35 mode with a speedbooster, but to cover the field the lens shall be a FF lens. Otherwise you will lose the corners
This is the theory, but there is another problem.
The speed booster requires some place to install some glass pieces. The design is possible if the lens is Canon EF and the camera Sony, because the flange focal distance of the EF lens (SLR, not mirorlens) is big. But if the lens is designed for a Sony E mount, the flange focal distance is extremely short and it will be very hard to design an optical device to install in between. So, there is few chance to see a E-mount to E-mount speed booster one day on the market...
Practically, the speed boosters were designed to use old SLR FF lenses on mirrorless S35 cameras...
Ok here's my question any help is much appreciated.
Is there an E-mount to E-mount speed booster? Or a FZ to E-mount booster?
I'm coming from a Sony F55 which I love but I'm switching to the FX6. I invested in a Fujinon MK 18-55 lens that I also love and don't want to sell, but the lens is for S35 sensors and the FX6 only shoots HD in S35 *eyeroll. So I'm trying to figure out a way use this lens with the FX6. I've converted the lens to FZ mount on the lens that enabled me to use it with the F55.
