NO More Sensor Dust, a Creative Solution !

In the days of film it didn't matter: Dust. Ok, sometimes if you got unlucky dust manifested itself by leaving "telegraph lines" on your film but this could be prevented by being reasonably careful while changing film. Fast forward to the digital age, dust has become more of a problem. Well, at least mentally ... I´d never thought that I´d do what I did to solve it. Please read on if interested !

To be honest, since I exclusively use Fuji mirrorless cameras I´ve only once had a real problem with sensor dust: Happened to my (meanwhile sold) X-T1: Sent it in for cleaning as the dust was underneath the sensor cover glass - discovered that it didn't disappear after wet cleaning the sensor (Jeezus, just doin´ that little operation nearly gave me a freakin´ heart attack ! ;-)

Otherwize, touch wood - didn't have to clean a sensor again since then coz the fear of dust - Amathophobia ;-) has driven me to become a kinda "one lens guy", reluctant to change lenses when out on the street and IF necessary really sweating about it ... While this restriction has been good for my creativity I was missing the peace of mind I´d experienced in my film days. So I went out & got myself the Fujinon XF 18-135 mm / f3.5-5.6 R LM OIS WR zooooom - Oh boy, already the name of that thing´s longer than you can say in one breath !

Hang on, say again ? Yes, a Z-O-O-M lens ! Ya know ? Those telescopic barrel shaped things, filled with hundreds of lenses, way too dark max. apertures, and usually having a bad reputation of delivering soft, soggy, unsharp, contrast-less images. And I´d always used primes till now ... So, even if this decision´s gonna cost me at least half of my numerous, faithful blog followers ;-) I´ll do my best to try to convince y´all otherwize - see below my sneak review of the Fuji XF 18-135 mm WR zoom lens (comparable to a 27-203 mm zoom on full frame) !

All the images on this post were taken with the Fuji XF 18-135 mm WR zoom, and I gotta say I was very positively impressed about the amazing flexibility and image quality this lens offers, especially also at the longest focal length (normally the Archilles´ heel of tele-zooms). It truly is a "one lens" solution which can replace a bag full of primes (with some caveats, see below) ! So, no more need to change lenses ! I felt like liberated & it gives me a wonderful peace of mind regarding sensor dust. This WR (weather resistant) lens also uses a clever "Air Ventilation" feature (see on the right) to effectively prevent the pumping action of the zoom sucking dust into the system !

I really appreciate the combination of an 18 mm (27 mm FF equ.) wide-angle all the way thru to 135 mm (203 mm FF equ.) telephoto, all in one lens. On my DSLR´s (a long time ago) I had 3 f2.8 L zooms (from 16 to 210 mm), but always seemed to end up using the focal length extremes of the respective lenses´s zoom range. Here the Fuji lens offers much more flexibility and sufficient image quality over the whole zoom range that I now often also use the focal lengths in between the extremes:

Yes, the maximum opening from f3.5 at 18 mm to f5.6 at 135 mm is a bit restricted, but the images IMO are already quite punchy and absolutely useable at max. aperture ! The integrated OIS (optical image stabilization) system does an amazing job. It allows me to compensate the modest max. aperture (at least for static subjects) by allowing me to use an up to 2 (18 mm) -4 (135 mm) stops slower shutter speed. The advertized 5 stop difference can only rarely be achieved in ideal conditions with solid bracing of the camera. So, the only real caveat from my point of view is the limited background separation due to small f5 - 5.6 max. apertures at longer focal lengths, however the bokeh is quite smooth !

I never thought I´d love using a zoom (even less with a 7.5 X zoom ratio) ... But after intensive use the last week I can really recommend Fuji´s XF 18-135 mm WR zoom as a "one lens" solution for travel, casual walkabouts, all-round use, etc. Granted it ain´t as sharp as Fuji´s amazing primes  so I continue to use those for critical assignments. Summarizing, the following positive things can be said about the XF 18-135 mm WR zoom:

  • Extensive zoom range covering all the main focal lengths from wide-angle to telephoto. No need to change lenses, no dust worries, no fuss and fast adapting to situation
  • Good image quality even at the extreme focal lengths and at max. apertures, decent Bokeh
  • Fast accurate and silent autofocus (with X-Pro2). Front element does not rotate
  • Amazing in lens image stabilization (OIS) allowing up to 4 stops longer shutter speeds
  • Portability: acceptable size & weight, no problem to hand carry around all day on X-Pro2
  • Build quality: Weather resistant, metal bayonet, filter thread & rings (focus & aperture), high quality plastic lens tube. Tight, compact feel and smooth operation. No lens creep
  • I like the aperture switch: The lens remembers the last manually set aperture value when switching back from auto to manual
  • Absolutely use-able macro capability (up to 0.27 X, min focus at 45 cm)

And here the cons:

  • Some chromatic aberration - can be corrected in post
  • Modest max. aperture limits ability to stop motion and potential for background separation
  • Zoom ring has increased resistance towards the long end of the zoom range (because of the weather sealing I think). Always need to double check if I really have the max. setting
  • Aperture setting not visible on lens, need to check viewfinder or LCD

Didn't´t say anything about price yet - I think that 899$ / 850€ is a fair price for what you get but it ain´t really a bargain ...
