  • Nikon NC Filter vs Hoya UV Filter. The difference is clear

    What filter is attached to the lenses that you are using now?

    Ever wonder what is the difference between a high-grade UV filter and a low-grade UV filter? Have you ever find out?

    Here is a simple experiment you can do it at home.

    Objective: To compare the quality of the available protective filter and rank them accordingly

    Items:
    1. One piece of white paper (a regular A4 paper will do)
    2. Choice of your UV filters

    Methodology:
    1. Put all the filters on top of a piece of white paper.
    2. Check the clarity visually to get a visual confirmation
    3. Snap a photo of the filters arranged
    4. transfer the photo into your Photo processing software (ACDSee pro will do)
    5. Increase the Level and Contrast until you tell the difference.

    Experiment report:
    Refer to the picture #1 attached. The one left is Nikon NC Filter (worth RM230), on the right is Hoya UV Filter (worth RM120), and on the top is Marumi UV Filter (worth RM30 at most).

    You will find that the Nikon NC Filter is the clearest among all three, Hoya UV Filter is slightly darker with a little yellowish, and the Marumi UV Filter is the darkest. Yes, I know it rather difficult to tell the difference especially based on a picture, but trust me, it is very clear if you see the experiment right before you.

    In case you still can’t tell the difference, Picture #2 I attached is the same photo with high contrast to help you see better.

    Conclusion:
    The type of materials that called thin glass may not look as simple as you might think of. The thin glass itself will affect the penetration of light.

    So do you still think the simple UV/NC filters are made equally? Think again, what lenses are you using now? Perhaps it is time to evaluate your filters attached with it.

            I don't have a B&W filter with me, but according to the last test with my friends it isn't as clear as Nikon, but comparable with Hoya standard only.

              Wow.. I didnt know the difference was that apparent.
              YOur study results will somehow affect HOya sales d. LOL

                Not really lah...

                My previous experiment on Eneloop VS Imedion will affect Imedion demand for sure, but not this one.

                RM230 vs RM120, the difference is you can drink extra 100 times of teh tarik ais.

                No point to get Nikon NC if you want something just to cover the toysrus 70-300mm F4.5-5.6 lens.

                    The purpose of the UV filters is to stop UV affecting the images. Do you have instruments to generate UV light? No?

                    Then is you were to just use a good plain glass without effective UV filtration coating, then the light would be even brighter that that using the Nikon filter. So it's much more that what meets the eye. But it's a good comparison, proving cheap filters are not worth the money spent!

                      Wow, seems like you have almost all the filters available in the market. I wonder how many lenses you have in the first place.

                      If you think you can use the above photo as benchmarking, you can't. You need to redo your composition and resubmit your photo.

                      1. The photo taken must have an even source of lighting on all four corner of the photo in order to have accurate benchmarking.

                      2. Noticed your photo is taken with a tilted angle, make sure it is taken straight on top, 90'. Use tripod, a professional tripod that can be used for product/Macro photography.

                      3. Increase the contrast using leveling of the photo taken, you will notice a few problems with your photo:

                      a. vignetting effects that from your lens. You need to take the photo without any vignetting. Try set the aperture to F8. Also check your DOF, it is too shallow.

                      b. the contrast inside the filter are uneven, and the bright side are pointing towards Kenko direction. Indicates there are one light source pointing at Kenko filter, uneven and bias towards Kenko.

                      c. the contrast inside Kenko filter also splits into half, above is dimmer, and below is brighter with a clear horizontal split. I guess the light source could be some kind of neon desk lamp or something similar happened shines towards kenko caused a slight reflection to your lens.

                        best lens filter review ever!
                        I have a NC filter for my 35mm and a kenko filter for my 18-105mm.
                        I'm going to replace the kenko (FOC from shop when bought by d90).

                          UV filters, as Noordin said it, were designed to stop UV light. Digital sensor are designed to ignore UV light. In othter words, the only effect the UV filter has is potentially degrading the output. Well, it protects the lens as well but I usually take the sunhood or lenscap for that. Think again ..
