Sorry I didn't do a video of the process, but I following the instructions provided by Sean, Guy and many others in some of the early WATE adapter posts. If you have the Leica IR filter, then it is very simple to remove the glass. Take a close look at the filter and on one side you will see there is a retaining ring holding in the glass. There is small gap in the ring and you just need to use a pointed object at the gap and pry the ring out. The Milich adapter has a threaded retaining ring supplied that you need to remove. Drop in the filter glass and re-install the threaded retaining ring supplied by John. All-in-all the Milich adapter is a great design which I believe was a collaborative effort between John and some of the more active members of this forum (not me).

Mr Milich did this for me free of charge when I ordered the WATE adapter. It is a bit more hazzle to remove glass from a B + W filter than a Leica filter, as you need to physically cut the mount.

There is the risk of damaging the glass with both the tool and the end of the ring when it comes out. I ruined one 49mm filter this way. Here's how I described elsewhere how to remove it, recognising it's Ok to sacrifice the mount to ensure the glass is unharmed:

 

1. From the back of the filter ring, look for the gap in the retaining ring.

 

2. Using a pair of wire cutters, make a cut from the back of the thread at right angles to the filter glass down as far as the glass, but not touching it, into the gap.

 

3. Take a pair of thin-nosed pliers and grip the thread on one side of the cut, then turn the pliers to "wind" the threaded portion of the ring away from the cut and out of the ring about 1cm or half an inch. Repeat with the thread on the other side of the cut. The aluminium is very thin at this point and will tear.

 

You can then easily remove the retaining ring with a finger and the glass pops out.

I'm sure that Mark has the right approach . . . .

Still, I got my retaining ring out with a fingernail - it really was that simple.

Russ at Glazer's, my shop in Seattle,USA did it for me without cutting anything. I watched him do it and believe he used a fine tweezers to remove the Leica retaining ring/ metal piece. I know of one other WATE owner who did it himself without the use of wire cutters.

the B+W glass is held in with a threaded retaining ring; you may need the Microtool to unscrew it; same tool is useful for installing the retaining ring in the adapter

I took a needle, bent the last 2mm at 90 degrees, and pulled the ring out by sticking the needle in the crack, under the ring, and lifting up. Was not too difficult, and if you are careful about how you angle the needle, it can't scratch the glass.

[marknorton]

I probably went at it like a bull at a gate and managed to scratch the filter AND chip the glass. Hence my sacrificial approach...

[sean_reid]

I've done a bunch of them using the simple approach and have never damaged glass or ring. Obviously, caution and care are in order, etc.

I followed Mark Norton's and John Milich's advice using pliers and Microtool. Figured that I would not need the Leica filter holder again and decided to play it safe. Worked exactly as described.

I used a jewelers screw driver to remove from a leica filter . Carefully that is. Eraser from a pencil to screw in the retaining ring. i also used a bath stop (rubber) to actual remove the glass from a B+W filter ring, used pressure.

Guy, everyone, I'm having trouble getting to first base! I ordered the adapter from John a few days ago. Finally back in Paris and decided to sit down on a lovely Sunday afternoon to mate the WATE and the filter adapter together... and I can't remove the retaining ring from John's adapter! I removed the little screw on the adapter, and have tried using a pencil eraser to get the retaining ring out of the adapter - no dice. Any suggestions? Thanks much / Tony

 

PS - I hope I do better when I get to step 2, removing the glass from the Leica 49mm filter, which I received as one of my two free filters...

Use bath or sink stopper of the soft rubber type possibly cut down to fit with a craft knife, alternatively i used soft rubber finger stalls of the type used to count currency notes (available from any stationary store) on 2 fingers.

i ship the adapters with the retaining very loosely fitted. try placing three fingers inside the retaining ring to lessen the chance of distorting it out of round when removing. there is no need to remove the tiny screw, by the way.

Thanks, Gabriel, I will give it a shot...

Excellent! The three fingers did the trick immediately! Thanks, John.

Hallo,

Look here: Leica M

[AGeoJO]

I just received a WATE filter adapter from JLM but I am still waiting for the 49mm filter from Leica. I will worry about removing the filter later on. Anyway, there is no instruction that came with the filter adapter . I wished it was supplied with some kind instruction. Oh well.

 

Now to the questions - Where do you actually put the filter or glass that you have removed from the filter ring? There is a tiny screw on the side, which I assume for tightening the adapter on the WATE. Is that correct? The filter adapter itself, is that just one piece or two pieces that are screwed together? There is a thin rubber O-ring on the smaller threaded part - is that the part where the WATE hood is screw onto? With the rubber O-ring inbetween?

 

I really appreciate any help.

It really is quite simple. The Leica filter will give you a glass disk which fits in the back of the filter adapter and you use the threaded ring to hold the filter glass in place. The filter adapter screws on to the front of the lens and the O-ring is used to tighten the thread as you screw it on to the lens.

 

The set screw serves two purposes - it replicates the aperture white dot and it provides a hard stop so that the adapter stops at the correct orientation; put the Leica lens hood on the front and it will then be square to the image frame.

 

It's worth working the threaded ring a few times before the glass goes in so that when you fit the glass, the ring goes in smoothly.
