Great review man, thank you! Just got the 100S and waiting for the 55 1.7 to arrive.

One tip for all FujiFilm cameras and yes I own three of them when you set to auto detect pick one eye why is this really important? Well what happens? Is it? Stop trying to jump to the other one? It will stop it moving around. You will get a lot more shots. Also set the sensitivity to 3. I would also up your shutter speed a little bit higher than you normally would now why do this we it's pure physics isn't it? If you've got the green box locked on Grip and rip it with a s high shutter speed? You will get better shots especially if someone is moving towards you. You really need the shutter speed to be quite high.

The real issue with the GF55 is that when you compare it to the GF80, shooting the same portrait scene, you'll notice something odd. When the overall brightness in other dark areas is the same in both photos, the face in the GF55 shot is noticeably brighter. Many people don’t understand what this means or why it happens. Here's the truth: the camera adjusts exposure based on the dark areas in the photo. So, with the same exposure time, the dark areas in GF55 photos are underexposed. This is because the GF55 uses ED materials like S-NBH58 and H-ZLaF90, which have lower light transmittance in the 500-400nm range compared to the Esfpl-55 used in the GF80. Specifically, S-NBH58 has a 1-6% reduction and H-ZLaF90 has a 4.4-41.5% reduction in this low-frequency light range. With two pieces of S-NBH58 in the GF55, the result is a significant drop in light transmittance and a lack of saturation in the low-frequency light (typically the bluish-purple diffuse light in dark areas). When the camera tries to adjust for proper exposure in dark areas by increasing the exposure time for the GF55, the bright areas, like the face, end up overexposed. If you decide to expose for the face and let the dark areas be underexposed, then try to correct the dark areas in post-processing software like Lightroom, you'll find the dark areas have a noticeable lack of saturation. This is due to the limited color information that the ED materials in the GF55 can capture. In simple terms, although the GF55 is a prime lens, the ED glass materials used make its color performance similar to a 70-200mm zoom lens with over 16 elements. It has sharpness but lacks the color quality you'd expect from a prime lens. Basically, a lens with this level of light transmission loss isn’t suitable for portrait photography.

Very interesting comment, I am going to check on this. Thank you
