Fuji X vs Sony A7 – the ultimate battle part.3 primes (35mm)

Sorry for the quality of the camera’s photos. I lost my files and had to make captions from a video.

In this last comparison of the two systems I will be focusing on 35mm primes and how the two cameras perform with them. The 35mm focal length is probably the most practiral as you can still make some landscapes with them, but at the same time also some portraits (half body portraits most probably) and use it in close spaces, where the otherwise super practical 50mm just wouldn’t work. In my opinion the 50mm is a great prime for open spaces, but as soon as we get near buildings, the 35mm takes over. This is a trend also amongst camera manufacturers, whereas the old (probably very old) cameras came with a 50mm lens, today’s most famous fixed focal lens cameras like Fujifilm X100F or Sony RX1 come with 35mm equivalent lenses.

As you can see from the first look, the Sony system, although being Full Frame, is actually the smaller (at leas shorter) one. This is of course caused by the Fujifilm lens being a F2, as opposed to Sony’s F2.8, This will make the Fuji faster, although remember that the depth of field will be roughly the same. Then with Sony you also have larger sensor so there’s less noise so you can bump up the ISO to get the same speed as with Fuji…. you know the story, photography is a game of tradeoffs.


At this point you might say, ‘I want to go with Fuji APS-C system because it is supposed to be compact, how is this compact if a full frame system is smaller?’ And indeed, even though the X-E3 is still smaller than the A7, an X-T2 would actually both be larger and longer.

Fujifilm X-E3 – auto exposure seems to be using quite differenc algothythms in both cameras (both photos are out of camera JPEGs)

This however is not as small as Fujifilm can get. With the Sony this is it, there are no smaller options unless you want to use the APS-C lenses like 16mm or 20mm, but then of course you might just as well go with the Fuji (or with a6000 series if a lack of proper telephoto lenses and only one dial to use in manual mode do not put you off).


With Fujifilm you still have the 27mm F2.8 to fall back on, which makes it a really pocketable system, something you just can’t get with the full frame.

The smallest you can get. Sony A7II with Samyang 35mm F2.8 and Fujifilm X-E3 with 27mm F2.8

Regarding the results you can see them yourself and make your own opinion, I however think that Sony’s full frame sensor still produces better images, although as with previous comparison the difference is really small and it makes it hard to justify the extra weight and expense. When it comes to the 24mpix version, I really find it hard to go back to Sony, eventhough I have to admint that after a month or so of usage I find the Sony system more comfortable. It lays better in hand (you just got to love the grip) and it can be operated one-handed which makes it really great for street and candid photography, bith styles where the 35mm primes play a very important role.

On the other hand Sony is no mach to Fujifilm when it comes to portability of the X-E3 with 27mm F2.8. If it only was easy to choose………
