H2 Fujifilm X-S20 vs Sony A7III – Full Frame or APS-C under $1500?

H3 Introduction

Hello my friends, in today’s video we will be comparing Fujifilm X-S20 and Sony A7 III. The X-S20 is a brand new release from Fujifilm that offers a pretty much unprecedented feature set within this price category. Sony A7 III is now a legendary full-frame dslm that completely changed the mirrorless Market back in 2018.

H3 Size and Build

The Sony A7 III is a significantly larger camera which is to be expected since it has a larger full-frame sensor. Both are actually about 12.7 centimeters wide but the A7 III is significantly thicker and it is heavier by 160 grams. Despite that, the size to Performance ratio that you are getting with the A7 III is still outstanding even by 2023 standards. The packaging of the X-S20 is just as impressive considering the features that it offers, especially the big battery and effective in-bar image stabilization. It is almost miraculously small. The build quality is very solid with both using a magnesium frame and feeling very solid. An advantage of the X-S20 is that most of the front side is rubberized. On the other hand, the A7 III is weather-sealed, and like the X-S20, it is not the best weather sealing out there but it is good enough for a reasonable amount of rain.

H3 Sensor and Image Quality

The biggest difference between the A7 III and X-S20 is the sensor size. The A7 III uses a full-frame 24-megapixel backside-illuminated sensor. X-S20 also uses a BSI sensor but it is a smaller APS-C sensor and it has 26.1-megapixel resolution. Importantly, it combines it with Fujifilm’s latest X Processor 5. The new processor allows the X-S20 to have some rather high-end specifications but one area where it doesn’t seem to make a difference is the still image quality. The conclusion in that regard is the same as in my A7 III and XT4 comparison: the X-S20 has slightly higher resolution but the A7 III has much lower pixel density. That means that the A7 III is much less demanding when it comes to the lens quality. With the A7 III, you can get very good results even with below-average lenses whereas with the X-S20, you need pretty good lenses but there is quite a lot of them available.

H3 ISO Performance and Color Science

Regarding the ISO performance, Sony uses REI ISO scale whereas Fujifilm uses SOS. The A7 III is generally cleaner by one stop and some change. The approach to the colors is actually very similar except the white balance which is very different. Fujifilm prefers rather cold tones, whereas Sony generally prefers warm tones.

H3 Autofocus and Video

Both cameras use hybrid face detection and contrast detection autofocus systems. The autofocus on the A7 III is still very capable even by 2023 standards. The subject detection is also solid with it having eye autofocus and performing very well in tracking tests. The video specs may be one of the most important deciding factors. Sony A7 III can shoot 4K video fully downsampled from 6K and has excellent video capabilities.

In conclusion, both the Fujifilm X-S20 and Sony A7 III offer impressive features for their price range. The X-S20 excels in compactness and in-body image stabilization, while the A7 III boasts a larger full-frame sensor and excellent low-light performance. Depending on your specific needs and shooting style, either camera could be the right choice for you.
