Edmund IR cut is identical to B+W cut

If this has already been mentioned, pardon my doubling.

 

I received my UV/IR cut filter from Edmund Optics (Edmund Optics - Mounted IR Filters) today.

 

As I've speculated in several threads on this forum, the Edmunds filter is apparently made by B+W.

 

... comes in a white box labeled "Made in Germany"

 

... comes with a quality control certificate labeled "Schneider Kreuznach"

 

... is in a black brass mount engraved with the size and "486 MRC"

 

The Edmunds filters are expensive, but last I checked, they are in stock.

Hey Howard!

 

Is the right filter size the "outer diameter" or the "thread diameter" as specified in their table?

 

For example, the 28mm f2.8 (the new one) is a "39 mm filter thread" says Leica in their spec sheet.

David- the right size is the thread diameter, i.e. the filter "thread diameter" spec needs to match the lens filter spec.

My question is whether you can then mount the lens hood back on with these filters.

 

I recall running into that with some B+W Uvs, and had to go with Heliopans which weren't as wide and allowed the stock hoods to be mounted.

 

Andrew- the Edmunds 46mm filter fits on the leica 50mm f1.4 lens and the integrated lens hood slides right over it. And the lens cap fits pretty nicely on the filter as well. Not sure yet about the fit on other lenses.

Hey thanks, John!

 

Well .... if that's the case then it's not immediately all that helpful for most lenses, is it? (in terms of filters to fit directly on Leica lenses ...) for example. ...

 

Leica lens filter size

 

28 2.9 39mm

noctilux 60mm

75 2.0 49mm

35 2.0 39mm

24 2.8 55mm

 

 

and the thread diameters listed on the Edmund site are:

 

46mm

49mm (a match!)

52mm

58mm

 

 

:(

That's correct, David, not all that helpful, but a least there are a few match-ups. The 46mm will also fit on the 35mm 1.4, however, which I have on order in preference to the 2.0. Still trying to explain to myself the logic of buying a $3k lens based on what $0.1k filters are available..... Leica morphine

Reason for the post was to reassure S Reid and others that the B+W and the Edmunds filters are the same.

 

I was also disappointed that the offered filters don't fit all my lenses. And I didn't make any comments about whether I would prefer the B+W/Edmunds models or the soon to appear Leica-branded ones.

 

My point was simply that the one filter I received from Edmunds Optical is in fact made by Schneider, the parent of B+W; and that Edmunds has some filters available, whereas a number of people have been unable to get the B+W's at the moment.

 

In addition: I've now got a filter for my Tri-Elmar. But where's my M8? :)

Modestly embarrassing post: I mistakenly ordered from Edmond a 489 filter when I wanted a 486 filter. Did not realize that until I had opened it and used it -- 46mm, on my 35 mm/f1.4. Now, it did the trick: my wife's black parka came out black, not magenta. This is, I found out later after double-checking my carelessness, an IR filter, but not an IR-UV filter. Does anyone know if I have just bought myself a world of trouble and need to get the 486? From the evidence, I do not. But thought I would check, numbskull that I am. JB

John- if you look on the Edmund website you will find a graph showing the curves of transmitted light for each filter. The 489 (labeled KG-3) still does a pretty good job, but starts to reduce transmission a little early in the visible light part of the spectrum. So you're missing a bit of visible light by using those. I would try to swap them, but others might not be uncomfortable using the 489's. Easy mistake to make- almost did it myself.

John--Don't worry, I almost did the same.

 

In fact, for wide angles, the 489 may be better because it doesn't generate the cyan edges.

 

Wait till Monday and let's see what Leica's solution is. If you keep what you've got, you can probably work out a simple tweak in a profile for your raw converter.

I posted this once before on another thread but it seems relevant to post it here as well.

 

There is a company Photo Equip, Accessories from PhotoEquip, which produces a product called FilterView, which could save a lot of money here. It consists of a 77mm filter holder with slits, and a series of step up rings. It screws directly into any lens with a 60mm thread diameter and the step up rings are for 39, 46, 49, and 55mm thread diameters. The FilterView costs $120.

 

I originally bought mine because when used with a polarizer the filter flips up to be directly in front of the viewfinder so you can rotate the polarizer until you see the effect you desire then flip it back down to the shooting position and fire away.

 

However I now see the big advantage to the product as being I need only one 77mm IR Cut filter to take care of my stable of lenses. Many dollars to be saved here.

 

I have no affiliation with Photo Equip except as a customer.

 

Hope this helps
