One of the really great things about the Fuji GFX 50s is the fact that it has a shutter built into the camera instead of it being in the lens. With a sync speed of only 1/125 of a second, on the surface, this may seem like a massive downside for the Fuji compared to the Hasselblad X1D which uses a leaf shutter mechanism. Instead, this one feature opens the GFX to a whole world of adaptable lenses and possibilities.
In my latest video, I demonstrate how the Techart EF-GFX adapter can deliver some incredible results. Comparing the Sigma 85mm f/1.4 Art lens on a Canon 5DSR to the Fuji GF 110mm f/2, it's clear to see how the 110mm is a better performer. However, once you adapt the Sigma to the GFX, you're able to achieve some very interesting and unique possibilities. The Techart adapter on the GFX allows full autofocus and aperture control with the ability to also use flash in your photography. This gives the Fuji a great advantage over the X1D because it allows you access to a huge range of lenses from the EF mount using autofocus, many of which can cover the Fuji's sensor entirely. The autofocus features do work well; however, due to the extremely shallow DOF on the Sigma/Fuji combination, it can be difficult to nail focus properly on the eye. The other aspect of being closer to the subject with the 85mm is that you're able to produce a more detailed image because the subject is larger in the frame and takes a larger portion of the available resolution.
