16 Aug Testing High ISO Performance with the Fujifilm X-T2 – Dan Bailey’s Adventure Photography Blog
Having shot with the new Fujifilm X-T2 during the past few months, (read my full review here) I’ve been extremely impressed with how well it performs at high ISO settings. Given that the X-T1 does quite well when shooting in low light, (here’s a pixel-to-pixel comparison of how well the X-T1 stacks up against the Sony A7r), I was curious about how they would improve the noise reduction on the X-T2.
We all know that pixel size plays a huge factor in how well a sensor does in low light. Since the new 24MP APS-C X-Trans III sensor actually has smaller pixels than the 16MP APS-C sensor on the X-T1, there would no doubt have to be some new magic under the hood in order to make up for this.
With the X-T2, Fujifilm has incorporated a few new technologies, including copper wiring instead of aluminum for better conductivity and faster signal transmission, improved signal amplifier and better noise reduction algorithms. The non-Bayer patter X-Trans sensor also helps reduce noise; the irregular pattern RGB pixel array helps the image processor better spot noise artifacts.
However, the biggest factor is the new X-Processor Pro image processing chip. It’s the backbone of nearly all of the X-T2’s performance enhancements. That’s what drives the faster autofocus system, faster EVF refresh rate and shooting frame rate, reduced shutter blackout and sensor readout time, faster image processing, as well as the ability to shoot 4K video and compress RAW files to 14-bit lossless format.
