Home Made filter holder for Nikon AFS 14-24mm f/2.8G

August 03, 2014  •  Leave a Comment

I just received my second Nikon afs 14-24mm f/2.8G lens. The first one was sold 2 years ago when I came back to Canon gear. Nevertheless, it is probably the best ultra wide angle lens going starting at 14mm (Roger Cicala from Lens Rental says the new Canon 16-35mm f/4L IS seems better wide open than the 14-24mm...). 

Before going to Nikon, I was using the 14-24mm on my Canon 5D II and was getting great results from 14 up to 20mm. That is when I ordered the SW150 filter system from LEE. I kept the whole LEE chi bang when I bought my 2 Nikon D800Es and did Tuscany using Exclusively Nikon gear (besides my Fuji X20). The problem with the SW150 is that it is a huge system: huge holder, huge filters and a heavy metal gear to put on the lens in order to use the filter. I needed a small bag just to carry the SW150 system. I came back to Canon last year for personal reasons: 5D III for landscape & 1D X for my wildlife shooting, and then this year, I bought the Sony A7R  ( which offers me the D800E results with the possibility of using my Canon lenses), for landscape shooting. 

I needed a very wide lens for my landscape and interior shots. I thought about the Canon 14mm f/2.8L II (been there), then the Samyang 14mm f/2.8 (been there as well) but none offered at the same time sharpness in the corners at f/11 & f/16 and as much linear without image deformation.

So I started to think about the Nikon 14-24mm again. Oh no, not the patio door filter system again. After surfing on the Web about ideas, I came across a video by Ben Jacobson talking about making a filter holder with a Nikon 14-24mm lens cap. I ordered the material and worked on it for about 3.5 hours over two days: I took my time and took a thinking break between two steps in my "creative manufacturing" process.

 

 

 

 

 

 

 

 

 

So here is the little recipe to make a home made Nikon 14-24mm filter holder that works without any vignetting:

Material you need:

1 Nikon afs 14-24mm f/2.8G spare cap (around $19.00 at BH)

1 X-PRO 105mm ring (I chose the one with the 105mm thread at BH $75)

1 X-PRO filter Holder ( $91 at BH)

1 sheet of black foam board 3/16th inch thick

Self adhesive velour or Flock paper #55 ( $20 at Edmundoptics for 2 sheets of 20x30in..yeas you can do your bedroom with the remaining)

a Dremel  with a cutting and a grinding tool

Here are the steps:

1. On the Nikon cap,

2. Use the Dremel to cut the bottom of the lens cap

3. Use the Dremel to grin the "lip" on the outside of the cap.

    Do this step by step so the ring (thread first) will fit right in but not too easily.

4. With the Dremel, grin the inside of the lens cap so it will fit easily on the lens hood. 

    Again do this step by step until the cap can cover the lens until the small wings of the hood can

    emerge a little pass the lip. This is to ensure there is no vignetting at all.

    Make sure the cap is really easy to put on the lens because we will cover the inside later.

5. Place the adhesive velour inside the cap. If it is too tight on the lens, remove and grind again.

6. Glue the adapter ring on the grinded lip of the lens cap

7. Install the filter holder on the ring.

8. There are 2 filter slots on the holder. The neutral filter will be used in the second slot (away from the lens)

    Let's create an anti-glare frame that will fit in the first slot to protect light from reflecting on the filter:

    Cut a 130mm x 130mm (or 130 wide X 140mm long) square in the foam board

    Cut a second square of 115mmx115mm centered inside the one you did, leaving about 15 mm of border all around.

    Then press the filter on two opposite borders for about 5mm with something flat to make the frame thinner,

    fitting inside the holder slot 1.

9. Insert the anti glare frame in the first slot

10. Install the kit on your 14-24mm and make sure the tip of the smaller wings of the hood can be seen when

      seen from the top, just passing or flush to the edge of the ring; this way, there won't be any vignetting

Voilà !

 

 

 

 

 

 

 

 

 

 

...and no vignetting, even on the A7R.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Cheers all!
