In 2011, the Fujifilm X100 took the world by storm, offering the style of a Leica M but at a more affordable price. We test its successor, the X100S, with upgraded 16.3-million-pixel sensor. Read the Fujifilm X100S review..

Noise, resolution and sensitivity

These images show 72ppi (100% on a computer screen) sections of images of a resolution chart, captured with the 23mm lens set to f/5.6 . We show the section of the resolution chart where the camera starts to fail to reproduce the lines separately. The higher the number visible in these images, the better the camera’s detail resolution is at the specified sensitivity setting.

Featuring the same 16.3-million-pixel sensor as the X-Pro1 and X-E1, it is no surprise that the Fuji X100S is just as capable of reproducing fine image detail. I cannot help but be impressed by just how crisp this detail is, whether it is hair in a portrait, blades of grass in a landscape or the textures of brickwork in a street scene.

For this test I have processed raw files using Silkypix, converted the images to Tiff files and then edited them, along with the JPEG files, in Lightroom.

Our resolution charts indicate that the X100S can resolve up to the 32 marker when shooting in raw format and using an optimum aperture such as f/4 or f/5.6, which is close to what we would expect from a 24-million-pixel camera with anti-aliasing filter. JPEGs aren’t as sharp as raw files, resolving up to the 31 marker and then tailing off more noticeably at the higher sensitivities.

Close the aperture down from f/5.6 to f/16 and image detail becomes a little softer, as we would expect, but the Lens Modulation Optimiser processing has reduced the impact of diffraction on JPEGs so that images at this setting are still very usable. This is good news for photographers wanting sharp images with good depth of field, such as when capturing landscapes.

The ISO 200-6400 sensitivity range can be expanded to ISO 100-25,600 in JPEG format only. Detail is sharp in good light using the lower sensitivity settings, and continues to be so in low light and when using higher sensitivities, with images remaining clean. At ISO 1600, detail in night-time street scenes is crisp. There is more of a decline at ISO 3200, but the X100S still performs well in both good and low-contrast light.

Image: This JPEG image has been shot at ISO 3200, where detail is still quite crisp because luminance noise is well controlled

    I recently purchased a new Pentax X5 which I used to photograph a wedding in York. The wide angle lens was excellent for groups and interiors and the film speed automatically changed when shooting indoors in low level light. The lens focussed all the way up to 4,000 mm for shooting wild life or any other use, such as photographing Angela Merkel in her office in Germany from the White Cliffs of Dover. Brilliant performer. Saves me from carrying my Hasselblad and a range of lenses. There are positives and negatives with every type and make of camera. This saves me time and space instead of having to change lenses.

    Great overview that is pretty accurate. I’ve had my x100s now for about 4 weeks, and as a previous x100 user, this is a real step up in image quality, iso range, AF, manual AF and ease of use. I have a Canon dslr that gives great images with right lenses, and in some circumstances it is better than the x100s. That’s the 60d with primes. But, for an all day multiple use camera with outstanding image quality, the x100s is very hard to beat. I havent tried the RX1 yet but plan too soon, although the price is right up there. I’ve been blogging about it recently at my blog click here to see… if anyone is interested. I’ve posted many different pictures and even a high speed sync flash setup that works up to 1/4000th of a second.

    I still think it is beautiful and would buy one just to sit on he side to stare at all day it is pure camera porn, ohhhhhhhh and it takes picture as well
