In a talk with the Japanese youtube channel カメラのキタムラ, the manager addressed exactly this topic.
Once again we rely on the bad automatic YouTube translation tool, and given that I am now on my last days of holiday, which I am spending isolated with my family because we got Covid for the first time, I am not really in a super mood to fight with the automatic translation all too much.
And yet, there are a few things I’d like to highlight for you.
The manager calculated the weight difference between being f/6.3 and f/8 at the long end, and the result was that by going with f/8 Fujifilm saved 400g of weight.
So the question for Fujifilm was, is it worth to add 400g in order to have a 2/3 stops faster lens? Evidently not, at least in Fujifilm’s eyes.
Other things the manager said:
inner part of the lens is made of magnesium, outside part of plastic, also in this case the goal was to save weight
white color to handle better temperature changes
inner zoom
3 front elements are heavy. When hold downwards, the lens would extend. The internal zoom solves this problem
four super ED elements to reduce chromatic aberration
The firmware included XF150-600mm f/5.6-8 compatibility for three Fujifilm cameras, the X-T4, X-T3 and X-S10.
This lead to the misunderstanding that the Fujinon XF150-600mm f/5.6-8 will work only with four cameras: the Fujifilm X-H2S, the X-T4, X-T3 and the X-S10.
However, that’s not correct.
The Fujinon XF150-600mm f/5.6-8 will work with all Fujifilm X series cameras. However, except for the four cameras mentioned above, the other cameras will have restrictions on some features and functions. The same is valid also for the brand new Fujinon XF18-120mmF4.
