Fuji Protector Filters

Question for anyone who owns a Fuji protector filter for their lens. I have the PRF-52 for my 35mm f1.4 lens and the PRF-62 for my 23mm f1.4. I noticed the light reflecting off the front of the filter glass is different between the two filters even though they should have the same coating. The light reflecting off the front of the PRF-52 is PURPLE while the light reflecting off the PRF-62 is BLUE. The attached photo illustrates this using an LED strip as the light source. (The filters are mounted to the lenses in the photo, so ignore the extra reflections from the lens elements.)

 

Can owners of Fuji filters tell me if they see the same colors reflected off their filters?

 

Both filters use Fuji's Super Electron Beam Coating (EBC), so I was expecting the same color in light reflection.

 

I wonder if it's possible one filter is fake. However, all the packaging looks legitimate, and I have yet to notice any striking differences in optical performance.

 

Thanks for any input from you folks.

Hi Vince,

 

Quite interesting observation, I do not have X100 anymore but looked at my other lenses (all with fuji protectors)

 

On my 62mm diameter filters (23 f1.4, 56mm f1.2) the reflection is more blue'ish

The same on 67mm (16mm f1.4)

On the 72mm diameter (10-24mm f4 and 50-140mm f2.8) is more green'ish. Please have a look at the photo attached.

And slighly more greenish on diameter of 77mm (16-55mm f2.8)

 

 

It looks like the reflection depends on the filter diameter. Has any one got other lens/filter to try or have different results may be?

 

Regards,

Vladimir

Vladimir, thanks for checking your filters and posting the photo.

 
I'm now adding the filter for the Fujinon 35mm f2 lens (PRF-43) which reflects blueish, very similar to the 62mm filter (PRF-62). See attached photo.

I obtained a second copy of the 52mm filter used for the Fujinon 35mm f1.4. The reflected light is not purple like the first copy, but rather yellow. See attached photo. 

 

Strange. I wonder why the color of reflected light differs when all these Fuji filters should have the same Super EBC coating.

      ISO and exposure dial’s misbehaving. Need help

      By Michaelb5 · Posted

      Hey everyone, I am new to the fujifilm system, and I just received my X100vi about 15 days ago, and yesterday I noticed that ISO and exposure dials are acting up. I spent hours watching YouTube videos and reading forms without finding any solutions. Using ChatGPT or Gemini also didn’t help. My issues are the following: If I want to set my ISO at a specific value then the camera LCD/EVF shows a totally different value. For example, I have shutter manual, aperture manual and ISO dial at 6400, the camera shows ISO at 4000, when I take pictures it will show ISO at 4000 and not 6400. When I try to choose another ISO value it will skip some of the available values that are shown on the dial. Another issue I am having is when my exposure dial is not set at specific value, then I cannot set ISO to Auto no matter what value I select on the dial. If I do select the different exposure compensation values, then I choose A for ISO, the camera will activate the front commend dial to manually change ISO values. To get in Auto ISO, the shutter speed cannot be set in auto and the ISO dial should be set at 125, when I turn the ISO wheel, it seems like the numbers are misaligned by one value, If I put the dial on A with shutter speed manual, then it will trigger the front commend dial. The other issue that I am having is when I have Aperture, shutter speed and ISO on manual, If I change the exposure dial compensation + or - , it actually changes the exposure of the picture as well as the ISO value, which as I understand, if Camera is in full manual, the exposure dial should do nothing. The last issue that I am having, if I do have ISO in manual at a set value, and adjust exposure compensation dial, it alters my ISO instead of my shutter speed or my aperture, even though ISO is in Manual and the other two dials are in Automatic. I am not really sure if all of this is by design and I am just not understanding how everything works together, but it seems really odd how everything changes. Resetting the camera settings didn’t help.

      Remote Release suddenly stopped working

      By FSND · Posted

      I also have the eaxct problem with my X-T5. The remote used to work, but not anymore. I also get the light coming on on the camera back, and autofocus will happen, but no shutter release. Since I use the 2 or 10 seconds timer more I don't know if a firmware update is the cause of this negative change. I actualley only use the wired jack-remote for action release on a tripod.  Did anybody find a cause, and even more assisting, a solution?

      On my XPro 2 the rear command dial, when pressed, can cycle through 3 different magnification levels in the OVF.
