Shaving The Nikon 10.5mm Fisheye

Talking about shaving the Nikon always reminds me of a lunch I had with friends one Sunday afternoon.  We were eating bread rolls with meat & salad when I happened to read the label for the ham.  It read ‘Lightly Shaved Hungarian’ which none of us had heard of, so I pronounced, “I’ll have a lightly shaved Hungarian please, my favourite kind!” We all cracked up laughing, my wife included.  Not funny?  I guess you had to be there

All joking aside, shaving the hood off the Nikon 10.5mm is a serious although not too difficult process.  If you’re not certain you want it shaved, turn back now as you can’t glue the hood back on later.  Although you could have it repaired with a new one, at considerable expense I expect.  In fact talking with NPS Australia (Nikon Professional Services) at a motor race I heard the best example of a shaved 10.5mm they’d ever seen was one done ‘professionally’.  According to them a gentleman bought a 10.5mm and a hood as a spare part.  He had the spare part hood cut perfectly, then had Nikon install the cut hood onto his new 10.5mm.  I’m told the result looked like it came from the factory.  The other end of the scale looked more like a dog had ripped the hood off with it’s teeth

The method I’m about to describe will provide a good (although not factory) finish, and require about $6 worth of tools from your local hardware store.  It requires no workshop or other gear, and I actually performed the procedure while staying at a hotel in Sydney.

 

Required Tools:

1)  Small hacksaw, with very fine teeth that have no warped pattern, ie the teeth run perfectly straight.  The example shown here cost me Aud $4.95 at the local Bunnings hardware store.  I looked for an extra blade, but all the examples they had contained the warped pattern in the teeth which I didn’t want.  I should have just bought 2 hacksaws, but I was too cheap. (Note: you don’t need ‘the’ hacksaw I’m showing, any hacksaw will do the job, but a small one does give you more control, and feel as you cut through the plastic.)

2)  Electrical tape.

3)  Pencil.

4)  Sheet of paper.

This image also shows masking tape which I didn’t end up using.

Procedure:

Step 1

Figure the point at which you will cut the hood off.  I chose just under the lowest point of the hood petals.

Elevate the pencil a little (I did use the masking tape after all) and rotate the lens while holding the pencil against the hood.  This will mark out your cut line.  It will be rough, but don’t worry, we’ll deal with that in the next step.

 

Step 2

Using the electrical tape, mask the bottom of the line drawn in step 1. Be sure not to cover the line.  Run the tape around the lens 5-6 times to build up some depth of tape.  We’ll use the ledge created as a guide for the hacksaw.

 

Step 3

Cut a piece of paper to the approximate circumference of the lens, roll it in a circle and slide it between the lens & the hood.  I jammed it in quite tightly (as shown in this photo), this is not necessary and will likely leave you with a few bits of paper stuck in there when you remove it later.

 

Step 4

Tape the top of the pencil line, which will also cover the paper and hold it in place.  Be sure to leave just enough gap between the 2 rows of tape for the hacksaw blade to comfortably slide.  You’ve now created a channel for the blade to sit in, reducing the chance of blade slip or cutting at the wrong angle.

 

Step 5

Now for the fun bit… start cutting.  I went deep first to find out how much I needed to cut before I hit metal. I then worked my way around the barrel, cutting each section to the metal before moving on. You can feel when you are through the plastic & cutting the metal… it’s a VERY different feeling on the hacksaw.  You can also see the white paper through the cut… assuming you haven’t removed the paper already with your blade.

My blade became quite blunt 1/2 way though. This didn’t cause any issue with the cut, but certainly increased the cutting time.  I spent about 20mins carefully cutting.

I have seen a shaving tutorial that used a coke can cut up (ie very thin metal) instead of paper between the lens & hood.  This would be better, but I didn’t have the tools or time to muck around with it.  In the end the metal barrel of my 10.5 has a few small scratches on it, which don’t bother me at all.

In this image I have basically cut through the entire lens hood.  You can see the paper through the cut in may places.  You may also make out the few bits of scratched metal where I’ve taken the black paint off the lens barrel.

 

 

Step 6

Gently remove the hood once you’re sure you have cut through all the way around.  You’ll see a result like this.  I had a few tiny bits of paper stuck in the lens barrel, if you don’t jam the paper in hard you shouldn’t have the same problem.

 

The Final Look.

When finished I realised I could have made my cut line a millimetre or 2 higher, ie right on the corner of the hood petals, rather than under them.  The lens works perfectly.

Here’s a quick overview of my shooting method from the Panoguide forum:

G’day,
There’s been heaps of great comments already. I’ll just state for the record owning a D200 & D700 what I do.

D700 + Nikon 16mm Fullframe Fisheye = heaven 😉 Same FOV as D200 + 10.5mm requires 6 + 1 etc.

I have shaved my 10.5 and also use it on the D700 for pole shots shooting 3 around at 0 degrees on a 360precision Atome. The Atome has a ring which attaches to the lens, and acts as a quick release, so I leave it on the 10.5mm at all times. Works beautifully.

I’ll give Han’s recommendation a go and try 4 shots around as well… I did find with 3 shots auto CP generation wasn’t brilliant. Here’s 18 pole shot examples I did at a motor race in October: with D700 + shaved 10.5mm + 360P Atome + pole/rotator etc.

D700 has ‘auto’ DX mode when a DX lens is attached. Like the D3, that can be turned off in the menu.

There is no problems having the hood off the 10.5mm. Just need to be a bit careful not to bang it on anything as there is no protection for the lens. Also, as with any lens you’re shooting panos with, the focus should be taped down so it doesn’t ever move.
