Hi,

 

I have read a lot of reviews of the 16mm 1.4 WR which praise it for sharpness, contrast and color. However, Auto Focus they all seem to agree upon, is good, but not exceptional, so e.g. street photography is out of the question. 

 

One thing I noticed though, was that all the reviews (that I found) was from before the 29th of June 2015 where Fuji released the 4.0 firmware.

 

So my question is: Has the 4.0 update improved upon the 16mm's AF performance?

 

And: Does the 16mm use a linear motor for AF or an older (slower, more noisy) system?

As I remember from toying around with one a while ago, it never was slow. And compared to my XF 27mm F2.8, it's very quiet.

It does not have the "LM" designation, so the autofocus motors are no linear motors. Instead, this lens uses a coreless DC motor. Those motors are known for very high acceleration. And since the XF 16 is a wide-angle lens, the focussing groups don't have to move that far to focus.

I do street with the 35 ƒ1.4.  The 16 blows it away.  There are a lot of people who do street with the 18, the 16 blows it away too.  I don't know who said you couldn't do street with the 16, but they were lying..

 The reviews. Among them this one:

But, if you all agree it is no slouch, it will certainly be my next Fujinon glass :-)

"– Autofocus is just a hair too slow for street photography."

​Most would agree that could be considered a general statement about shooting on the street with any camera, hence why most shoot manually and zone focus.  Plus, the guy is not much of a in-depth reviewer, in all honesty.

      Looking for Full Frame lenses to adapt to GFX

      By thelostkiwi · Posted

      I also use a Nikon to GFX Fringer and it works very well.  24mm f/1.8 vignettes so best used on 35mm mode.  50mm f/1.8 covers the entire frame very well with no issues and is a superb little lens. 105mm Sigma vignettes slightly but is perfectly usable. 300 f/4 likewise the 105.  I have a 70-200 f/20+.8 incoming to test so will report back but I'm expecting a little vignetting.  Even in 35mm mode the image is still 60MP and if you're prepared to manually crop and correct you can get 80-90 MP images.  I also have a C/Y to GFX adapter.  The 24mm Sigma Superwide vignettes strongly. Ditto 28-80 Zeiss Sonnar. 80-200 f/4 Sonnar is perfectly usable. All work fine as 35mm mode lenses.  I also have an M42 adapter which I tried with the Carl Zeiss Jena 135mm f/3.5 with good results.

      Ahh, the infamous brick wall photos… 😀 According to internet lore, if the dng converter does not properly apply the corrections, you can have it apply custom profiles that should work for you. How to do that is waaaaaay outside of this comment’s scope, but there are plenty of sites listed in the search engines that step you through the processes. Best wishes.

      Image correction with GF20-35

      Jerry Thank you very much. That is extremely helpful. It seems that the camera and the lens have the latest firmware update, so it appears that the corrections should be applied automatically. The lens arrived this afternoon and I took some quick test shots, in which the correct lens information appeared in the EXIF files, so that sounds good. I used Adobe DNG converter to convert the Raw (RAF) files, and then opened the DNG files and saved them in PSD format. However, with a beautiful, clear, cloudless blue sky, there were no lines near the edges to check if distortion had been corrected. Another day I plan to photograph a brick wall. Thank you for your help.

      Typically you need to make sure the lens is compatible with the camera, i.e. check the lens compatibility charts for your camera, then make sure the respective firmwares are updated so older issues are resolved. After that, each lens has a manufacturer’s profile which will be embedded into the raw file meta data for the images captured using that lens. From there, it is up to the raw conversion software to apply the lens correction to the image. Different converters do that differently, some automatically, some only if a setting is turned on. For in-camera jpegs, the on-board converter does the corrections automatically, assuming the camera recognizes the lens, it applies a generic profile otherwise. I do not know if that can be turned off or not.
