Fujifilm Manager Calculates Weight Saving Between XF150-600mm f/6.3 vs f/8 at Long End


When we first shared the rumor of Fujifilm developing an XF150-600mm lens, many hoped it would not be slower than f/6.3 at the long end.

But then, in April 2022, we anticipated here that it would be f/8 at the long end.

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
  • can be used with teleconverters
  • linear motor
