Fujifilm`s new X-H1 sits above the X-T2 in the company`s X-series APS-C lineup. As well as offering several enhancements in its core stills photography feature set, the X-H1 also brings high-end 4K video capture with up to 200Mbps capture and 5-axis in-body stabilization.
At the X-H1`s launch in Los Angeles last week, we sat down with the camera`s product manager, Jun Watanabe, to get a detailed look at the new camera. The following interview has been edited for clarity and flow.
Jun Watanabe is the Manager of Product Planning in the Sales & Marketing group of the Optical Device & Electronic Imaging Products Division at Fujifilm.
Fujifilm has stated previously that IBIS would not be possible in X-series cameras because of the small imaging circle of some XF lenses. What changed?
We have spent the past two or three years developing a system where using both hardware and software, we can cover [the necessary] imaging circle. The most important thing is precision. Because a sensor with IBIS is a floating device, it has to be perfectly centered and perfectly flat. We had already achieved a sensor flatness tolerance down to an order of microns, but the challenge was to maintain this precision with IBIS.
A laser measurement device is used during the process of manufacturing the image stabilization unit, and the assembly process also includes inspection and adjustment of each individual camera. For that reason, a micron order level of sensor parallelism is realized even while IBIS is activated.
A chart showing CIPA figures for image stabilization benefit of all compatible XF lenses, when used with the X-H1. As you can see, the least amount of benefit comes when the 10-24mm wideangle zoom is used. Users of the vast majority of XF lenses should see 5 stops of stabilization benefit.
Are there some lenses that will deliver better stabilization than others, as a result of having a larger imaging circle?
Yes ...
