That camera, by way of comparison, has a 0.74x magnification, whereas the Fuji X-T1's finder boasts 0.77x magnification. The huge news about the Fuji X-T1 - literally - is its electronic viewfinder.įor one thing, it has the highest magnification seen on any earlier digital camera, besting even the Olympus E-M1. Incamera meter calibration rawdigger iso#There's also an Auto ISO function, and you can specify an upper limit on sensitivity between ISO 4 equivalents.Įlectronic viewfinder. The result is a sensitivity range of ISO 200 to 6400 equivalents, expandable to encompass everything from ISO 100 to 51,200 equivalents. This is said to have been achieved thanks to a redesigned circuit board which, presumably, induces less noise during readout. Although both sensor and processor are unchanged, the Fujifilm X-T1 extracts better high-ISO performance than does the X-E2, according to its maker. (That is, if you press the shutter button too soon, it actually takes longer to get the first shot.) Incamera meter calibration rawdigger full#Fuji doesn't provide a full startup time, but we found the X-T1's power on to first shot time to be 1.4 seconds in our testing, with a pre-press penalty. If the power-off threshold time is exceeded in High Performance mode, the camera will not continue to drain its battery, but will take a longer time to start up. (In earlier cameras, Fuji listed the time as being as long as 24 minutes, but there's no figure provided in the X-T1 user manual.) Assuming the same timing as in earlier models, the X-T1 will continue to burn through its battery - albeit at a reduced rate - for un unspecified length of time after it is switched off. It's worth noting, though, that in this mode the camera isn't truly "starting up", but rather awakening from sleep. Shutter lag is manufacturer-rated at 0.05 seconds, which agrees with the 0.051 seconds measured by our lab very nicely, and startup time is said to be 0.5 seconds with the XF27mm F2.8 lens in High Performance mode. Our in-house testing found a time of 0.14 or 0.15 second, depending on the number of AF points used, but this also includes the time taken to set exposure and white balance. (We've not tested the X-E2, though, so can't draw a comparison ourselves.)Īutofocus is also swift, with a manufacturer-rated response time of just 0.08 seconds when using the XF14mm F2.8 R lens in High Performance mode, a figure that's unchanged from the earlier camera. In our lab, we found that claim accurate, with speeds of 8.1 to 8.3 fps, depending on file type. The Fuji X-T1 is said to be capable of shooting eight full-resolution frames per second with motion-predictive, tracking autofocus, up from 7 fps in the X-E2. Performance of the pairing is, according to Fujifilm, just a little faster than in that camera, however. Output from the image sensor is handled by Fuji's EXR Processor II, which is also featured in the X-E2. Of course all the normal caveats apply like: turn off any active D lighting, Highlight weighted metering, face detect exposure compensation and make sure no exposure compensation is dialed in.An ultrasonic vibration system is included to remove dust from the image sensor. It's an easy way to see if there are big metering problems. Your particular meter may read a bit higher or lower but typically within a third of a stop or so. The trick is a mid-toned subject (green summer grass works nicely) that's lit by direct sunlight on a clear day and fills your selected metering area. Working in full stops it's easy to check with different apertures and shutter speeds such as: Using reciprocity you can check other apertures, for instance: Incamera meter calibration rawdigger manual#So for instance at f/16 and a shutter speed of 1/250" you'd expect ISO for a centered exposure on the meter (or ISO in Manual with Auto ISO mode) to be 250 or close to it. If you stop down to f/16 the shutter speed should come very close to or equal the ISO for a mid-toned subject well lit by light on a clear sunny day.
