IMAGE QUALITY

The Fujifilm X-T10 is targeted to serious and advanced amateur photographers and features 16.3MP resolution (on an APS-C 23.6mm x 15.6mm X-Trans CMOS II image sensor), Fujifilm X mount, interchangeable lenses and a DSLR-style design.

We find the overall image quality of the Fujifilm X-T10 to be excellent at ISO 200 with low noise and excellent image detail. Image quality is very good up to ISO 1600. Noise starts to be slightly visible at ISO 3200 and images are very usable up to ISO 6400. At higher ISOs, images suffer from noise and loss of detail.

The Fujifilm X-T10 features its X mount that currently accepts 20 XF and XC interchangeable lenses with 3 more lenses (the XF35mmF2 R, the XF100-400mm and the XF120mmF2.8 R Macro) in the pipeline. The focal length multiplier is 1.5x. In the above picture, we show the coverage for the FUJINON XF18-55mmF2.8-4 R LM OIS [27-84mm equiv.]. The XF18-55mmF2.8-4 has a maximum aperture of F2.8 and a minimum aperture of F22. It has 7 blades with rounded diaphragm opening, 19 1/3EV stops and accepts 58mm diameter filters. The lens is optically image stabilized.

Closest focusing distance for the XF35mmF1.4 R is 30cm at wide-angle and 40 cm at tele (you’ll get closer coverage using the tele macro). The new AF system features an Auto Macro function that eliminates pressing the Macro button before shooting close-ups. This eliminates the need for one of the Cursor buttons being assigned to the Macro function, allowing you to assign a different function to the button. As you can see, this is not much of a macro. For real close-up photography, you would want to choose the XF60mmF2.4 R Macro (currently available) or the XF120mmF2.8 R Macro (available in 2016).

AF is fast and works very well in good lighting. In low-light, the camera will lock focus in about 1 sec. , which is very good.

As the above two pictures show, the Auto White Balance (AWB) is not quite accurate indoors under artificial lighting [I have two energy-saving fluorescent light bulbs on the ceiling]. The Fujifilm X-T10 allows WB to be easily set manually [MENU – SHOOTING MENU 2 – WHITE BALANCE – CUSTOM – SHUTTER] and this brings out the real colors. AWB works very well in natural light.

You can set the ISO on the Fujifilm X-T10 natively from 200 to 6400, plus the ability to have extended output sensitivity equivalent ISO 100 (L), 12800 (H1), 25600 (H2) and 51200 (H3). When the ISO Dial is set to A, the range is from ISO 200 to ISO 6400.

You can set AUTO ISO mode [MENU – SHOOTING MENU 1 – ISO – AUTO1, AUTO2 or AUTO3 – DEFAULT SENSITIVITY (200 to 6400), MAX. SENSITIVITY (400 to 6400), MIN. SHUTTER SPEED (1/4 to 1/500 sec.)] to specify default sensitivity, maximum sensitivity and at what shutter speed to start increasing the ISO.

The 100% crops above (area delimited by the white square) demonstrate that noise at ISO 200 is under control. Noise starts to be slightly visible at ISO 3200 but images are still very usable up to ISO 6400. At higher ISOs, the presence of noise is visible at full image size and with increasing loss of detail.

CA is well controlled and we couldn’t find much of it in our high contrast shots. In the above photo, the top left area delimited by the red square, and reproduced at 100% crop at bottom right, shows no purple fringing.

Long Exposure

Our Long Shutter Speed test is a torture test for digital cameras. Here we test whether (and how well) a camera can lock focus, provide accurate WB and obtain a correct exposure in extreme low light situations. The Fujifilm X-T10 passes this test very well.

The Fujifilm X-T10 allows the use of a long shutter speed of 30 sec. in ASM mode. This allows us to take some nice Night Shots. For this shot, I set the camera to Manual mode, selected a shutter speed of 30 sec., an aperture of F6.4, ISO 100. It’s too bad the full range of shutter speeds is not available in Program AUTO mode (slowest shutter speed is 4 sec.). There is a convenient countdown of the shutter speed in S and M mode but not in A mode.

Overall, the Fujifilm X-T1 has outstanding image quality (with low noise and excellent sharpness) that rivals and even bests some enthusiast DSLRs.
