Reach out! – Fujifilm 2x tele converter TC WR mini-review

Now THIS is a real odd-ball. – A guy who is completely and almost exclusively into shooting small prime lenses on the narrow streets of Århus in Denmark, suddenly reviews a 2 x tele converter for use on big heavy long reach zoom-lenses!

Usually when I get to test some form of Fujifilm gear, it’s usually because it fits my profile of shooting (I guess). But this time around it was a little different.

A little while ago I had the immense honour and pleasure of shooting ALL the X-series stuff as packshots for use in the banners over at (Go check it out, if you havn’t already). As part of this I was sent the Tele Converter XF 2X TC WR. I had a big trip to Iceland planned just 4 days after receiving it, so I asked if I could bring it along for some quality time along with the “Bigguns” the XF100-400mm and the XF50-140mm .
The guys at Fujifilm Nordic must’ve raised an eyebrow or two (as did I upon expressing that thought!) – But they said go for it.


Now, I guess what is the ever-important thing in a teleconverter is how does it retain detail and sharpness. The 1.4X teleconverter already does a fine job at this. And from the samples I’ve seen, and from my own experiments, the loss in sharpness is minimal. It is there, but minimal. So going even further in magnification would indeed mean even harsher demands for such a converter as the 2x.
You loose two stops of light when using the 2x teleconverter. The 50-140mm f/2.8 becomes a 100-280mm f/5.6 and the mammoth XF100-400mm f/4.5-5.6 becomes a 200-800mm f/9-11. This of course means that you need some extra punch in the ISO department, or use them on tripods and close the shutter speeds down when dealing with stationary subjects. The extra stop of ISO performance of the X-Trans III sensor in the X-Pro2 does provide some more room to manoeuvre without excessive noise.

So, what does it look like?

Well, its a tube…..with glass…. a little bit longer than the XF 1.4X TC WR. Basically a weird looking little lens. It retains all the build quality that we’ve (or atleast I’ve!) come to expect from the Fujinon XF series of lenses. Thats about it. Theres nothing too sexy about the look of a teleconverter!


Its weather resistant, so in conjunction with the big WR zoom lenses and the XT1 or X-Pro2 the weather will pose no threat to this little thing.

Iceland had some harsh weather while we were there, and there were times where the combo got quite wet from either hail or rain. So it passed the WR-test with flying colors.

Now, what about performance?

*A little disclaimer is in order here. My test version was a pre-production unit, so I do not know if image quality is final. Fujifilm is known for finishing lenses through firmware corrections right up until shipping.

As you can see from the images I did not test this converter on people doing weird physical activity aka sports. I did not test it on a roaring polarbear running towards me. I shot some seagulls, landscapes, deers and some kids. Not really the AF test of champions, now is it? – But suffice to say, the autofocusing did not suffer from using the converter under me given settings. The XF100-400mm could easily follow a bird in flight with the XF 2x TC attached.

140mm f/2.8 (280mm f/5.6)

If you’re into sports (for which this converter would prove invaluable for reach) somebody probably tested it under those circumstances.

Image quality I felt was good. It did soften my images somewhat at the longest end of the zoom ranges. I can’t tell if this was because of heatwaves, mist, OIS or me not holding my camera still! – All I know is that on the close end of the zooms the sharpness was almost indistinguishable from using the zooms without the converter.

The cameras didn’t have updated firmware to read the correct EXIF from the converter, so I was given the EXIF as if I was using no converter.

Now let’s look at some images, shall we? These images below are all taken with the XF50-140mm f/2.8 on the X-Pro2.

What you can see above is that if I stand close to the subject and is zoomed all the way in, you still get incredibly sharp images, but if you stand further away it doesn’t matter if you’re at 50mm or 140mm, you loose some detail. – But come on…. this is impressive territory for a 2x converter.

54mm (108mm) f/2.8 (f/4) at 6.5sec
66mm (132mm) f/11 (f/22) at 2sec

It does work very well on the long exposures. The extra lightloss can actually become an advantage here.


As I stated earlier, the autofocus didn’t present any issues to me. I tried to scare the deers as best I could, but apparently I’m not threatening enough! They just kept eating, or walking. Subject separation is good a these long focal lengths. You really draw out your subject, all the while pulling in the background.

140mm f/2.8 (280mm f/5.6)

Now, lets look at some of the images from the XF100-400mm f/4.5-5.6 in combination with the XF 2x TC. This is where you can really get that extra reach. The two images below are jpegs from RAW. Nothing done to them except export them and downsize them to 3000px on the wide end. They represent the reach you can get at 200mm and 800mm respectively.


I loved the mood that I could get at close to 800mm. Thats actually 1200mm in full frame eq. It’s crazy!

252mm f/5
372mm f/6.4 (744mm f/12)
100mm f/5 (200mm f/10)

Summa Summarum

So the first thing I would like to conclude is that the XF 2X TC WR is NOT a tool for my usual type of photography. That might crumble the entire foundation of this little write-up, but thats how it is. For the wildlife- and sportsphotographer using the X-series system, this little thing should without a doubt be an integral part of the toolkit.

The 2x teleconverter will give incredible reach, while maintaining decent sharpness. The compression of the scene is insane, and it makes for great scenic images when used for landscape photography.

Below you can find mixed sample shots. All shots taken with the X-Pro2 and the Tele Converter XF 2X TC WR and either the XF50-140mm or the XF100-400mm


My friend, fellow X-Photographer and wildlife photographer extraordinaire Ben Cherry also just published a great write-up on the 2x TC as well. Go check it out.




  1. As I first started reading, and as I reached the first few photos, I went “this is so different from Jonas’ style”, but as a testament of your talent, and your solidified “look”, this changes quite quickly back to “Recognisably Jonas” territory 😉

    Great review as always, absolutely love what you shot with something that’s not your traditional arsenal. That photo of the guy by the water (744mm f/12) right above the Motel shot (Which i also love) is phenomenal.

    Good stuff and glad for the early sneak peak of your Iceland shots 😉

  2. By far my favorite Fujifilm reviewer! Always looking forward to a new post from you Jonas!
    Great job, and gorgeous photos to accompany the article! Thank you!

  3. Your reviews are always a great read Jonas. in fact, your review of the X-Pro 2 is what pushed me off the fence towards getting it and I’ve never been happier with a camera. I’m glad to see your versatility in utilizing such long focal lengths, it speaks to your talent.
    Thank you for taking the time to write this up, it’s made me view teleconverters in a different light!
    I look forward to reading more!

  4. Want a converter that does NOT loose ANY light and costs $ZERO ???

    Psst: crop your picture in post! Especially good with higher res sensors, like X-PRO2 and the soon to be X-T2.

    Just a thought…

  5. Hello Jonas,
    Thanks for the article. Always enjoy reading your articles and see your beautiful photos.
    I got a question that intrigues me, can these teleconverters be used with prime lenses? If no, do you have any idea why?
    Thank you,

  6. Hi Jonas,

    I’d like to learn about your editing process.
    Love the colors on your pictures!!!

      1. Any idea why they made it that way? Did anybody here get to try slapping say the 50mm F2 on it?
        I would’ve thought teleconverters from all brands would work for zooms/primes regardless…

  7. Hi Jonas,

    I am new to your blog and love this review.
    Your review has made me regain trust in “teleconverters” after my horrible experience with a canon teleconverter.

    I have recently left Canon (sold all gear) and have decided to go with fuji.

    I am currently looking to purchase the 18-135mm along with a teleconverter for an upcoming safari trip.

    However am I correct to understand that these teleconverters are not compatible with the 18-135mm???

    1. Hi Jonas,
      I appreciate your article about 2X teleconverter and I have a question about it. I have a X-T2 camera and XF 50-140mm lens. I wish to buy this teleconverter but often I crop my sports pics. Using that teleconverter and cropping the images about 20-30% how much you may loose in sharpness? Acceptable or not?
      Thank you very much for you time, i can wait for your answer

  8. Re the compatibility of the 2 TCs (1.4 and 2.0) unfortunately they will only work with the 50-140 and 100-400 zooms and the recently released 80mm Macro which should please the ‘prime’ users. If you look at the TCs they protrude considerably on one side and that is the bit that is attached to the lens so a corresponding ‘hollow’ is required in the lens and only these 3 are designed to accept the TCs. I guess that is why Fuji are able to retain such such a good IQ compared to other brand TCs, even with the 2x. Its a shame as it would have been nice to extend the range of the XF 55-200 or 18-135. All a compromise and I would rather a reasonable IQ is maintained. As one poster has observed, cropping provides a solution. If the IQ is as good as Jonas has indicated, cropping a 1.4x or2.0x should pull in even more detail. I am waiting for a 50-140 plus a 2x TC to arrive so am looking forward to see for myself what the combo is capable of. Thanks to Jonas for his review as I was inclining towards the 1.4 as I was uncertain how the 2x would perform with the 50-140. Fuji released V3 firmware for the XT-2 on 30 November which includes an improved tracking algorithm which is supposed to be twice as fast as the previous version (and that was pretty slick) . Can’t wait to find out how it all works together. Will provide feedback if people would find that useful. I have spend hours reading other interesting blogs so perhaps time to put something back in!
