MORE POWER! I took this out of the box, attached the 2x doubler, put it right to the test. I can't believe that I am getting really fun images without using a tripod or monopod. I am trying to keep the shutter speed up, but I have gotten great results as low as 1/25th sec.

Lens was well packed and arrived in perfect condition. It is very sharp, even better than I expected. IS works very well even at the maximum FL of 400mm. I look forward to using it this summer for marine photos.

I had been looking forward to getting this lens and was keeping an eye on the price. I was frankly a bit surprised when I saw it advertised on Amazon at the cheapest price when I was ready to buy, but being a Prime member I saw this as a bit of a bonus.

Love it

Bought this a few months back and for some reason my review disappeared. Anyhow, this is the one and only wildlife lens for the Fuji X system. Yes its big for mirrorless, yes its plastic in parts, but IQ is surprisingly good even with the 1.4TC.

This is an in-depth review of Fujifilm's XF 100-400mm f/4.5-5.6 R LM OIS WR Lens. The lens was released in early 2016 and is Fuji's longest focal length lens and only super-telephoto zoom in its lens lineup at this time.
