Fringer Adapter GFX 100s 105mm f1.4

GFX 100s Fringer EF-GFX Lens Adapter

Here is a review of the GFX 100s Fringer EF-GFX Lens Adapter. I adapted the Sigma 105mm f1.4, 85mm f1.4, 50mm f1.4, 35mm f1.4, and 24mm f1.4. I picked the Fringer over other adapters because it has an aperture ring. This makes using the GFX system much easier. When compared to native lenses the autofocus was paralleled. The only difference I noticed was that the Sigma lenses were quicker to focus and much quieter. the 35mm and 24mm struggled a bit more to focus at f/1.4. I also experienced the Fuji 23mm f/4 struggling as well. So my conclusion is that wider lenses just don’t work as well on the GFX system when comes to autofocus.

You can watch the individual reviews to see how well they work on a Medium Format system. The 105mm, 85mm, and 50mm show little signs of vignetting which were easily corrected with a lens profile. The 35 and 24mm do have come corner issues that cannot be corrected. I had to crop the images with a 4×6 or 16×9 ratio. I’m fine with this since it allows me to get some creative wide images with some amazing depth of field and allows for lower-light portraits.

Canon EF 85mm II F/1.2 Review

Sigma EF 85mm F/1.4 Review

The Sigma 85mm worked great with the Fringer Adapter. I slightly outperformed my Fuji GF 80mm when it came to some green fringing. When compared with the 80mm the Sigma 85mm was just as sharp at F1.8. It was definitely softer at F1.4 but allowed for some extra character.

Sigma EF 50mm F/1.4 Review

the Sigma 50mm F1.4 was super fun. I had no vignetting that wasn’t able to be corrected in Lightroom. This lens is very sharp and holds up well at 100 megapixels.

Sigma EF 35mm F/1.4 Review

The Sigma 35mm F1.4 was fun. I did have some harsh uncorrectable vignetting on the corners. I had to crop into a 4×6 or 16×9, but this lens is still fun.

Sigma EF 24mm F/1.4 Review

The Sigma 24mm F1.4 had the worst vignette of all of the lenses. It still worked when cropping to 4×6 and 16×9.

Canon 100-400mm MK II and Tamron 150-600mm Tested

I tested the Canon 100-400mm F? 4.5-5.6 MK II and the Tamron 150mm-600mm F/ 5-6.3 G2. I decided that for my portrait and wedding work, the Canon 100-400mm was the lens for me. It was slightly sharper, had better Eye AF, and a bit more character. The lower aperture also helps when handheld. The Tamron 150-600mm was also a great lens and would be great for wildlife or sports.
