ND problem.

As some of you know & due to my recent shot i use B+W 3.0 10stop filter which is great but the problem being you can attach another filter stystem on the front of it but try getting it off again, near impossible, i was lucky enough & no more to get the Lee adaptor ring off but with great hassell, the point being you find yourself stuck not being able to use a GND, is there another way round this?

Re: ND problem.

I presume that the GND can be rotated much like a polarizing filter. Putting a filter on another has often caught me out. However, I have gone to the point of winding some electricians tape round the filter on the lens side to hold it on the lens, then using a some thin leather wrapped around the outer filter to aid removing it. Nikon's old 52mm linear polarising fllter was/is brilliant as it has limiting stops that stop it from freely spinning and thereby allowing you to get a purchase of the filter to remove it. Next to using bayonette filters like the Hasselblad this was a good solution but everything seems to be geared to a profit margin these days rather than giving users sensible designs.

Re: ND problem.

Use a pencil to put some graphite into the threads before fitting - makes all the difference to getting it off again

Re: ND problem.

The problem i had a while ago GS was that i had the b+w on then wanted to add the Lee GND to it as a result the lee adaptor ring got stuck onto the B+W filter, what does the graphite do mark?

Re: ND problem.

Mark has nailed this one

I'd recommend using a 2B or softer pencil - with care not to overdo it - softer graphite will transfer better to the threads.

I also carry a pair of filter wrenches as they can be very precisely positioned even on a rotating mount. They are quite cheap to buy.

Re: ND problem.

Nice one! That's the stuff! Use sparingly on filter threads - more generously in locks!

Re: ND problem.

It would Shane, but I would not use it as it will be difficult to apply and keep it off the filter and lens surfaces. A pencil can just be run around the threads very easily with minimal if any 'overspill' and that can be puffed off with a blower.

A pencil is also cheaper and can also be used to write things down too!!

Nice one Mark Sometimes you just forget the tricks you used as a kid - too long ago to remember ! I have a set of filters that are stacked with end caps, from the days of film when 52mm was the standard for Nikon. Many's the time I cursed when these stuck, and never thought of this simple trick - well sorted !

A top tip !

Re: ND problem.

Good tip mark tried it out on another filter 1st & it worked great so pencil will be going into bag but then tried it with the B+W filter & guess what it got stuck again, it does not like the Lee adaptor ring, played about for at least 2 hours again but no joy till i tried it 1 more time again & hey presto, so anyone else please do not attatch a B+M filter to anything else but another b+w filter.

Re: ND problem.

I guess that there could be a slight mis-match in the threads. As with all mass produced items from lots of makers there will be items at both ends of the tolerance scale.

Can you use it without screwing it right in? Is it worth buying a different adaptor ring to hopefully avoid this issue?

Re: ND problem.

Once you put it on with only a slight turn your in a problem,i thought it might be the threads so i screwed another b+w filter on to the front of it & off again without any problem, can you get a filter ring that is 77mm on both ends?

That does not sound right. Presuming there is no damage to the threads maybe there is something wrong with your 10 stopper thread? Might be worth contacting B&W to tell them what is happening and see what they say.

Re: ND problem.

Result! Thanks for sharing. Presume you are sandwiching this between the lens and filter, so are there any vignetting problems?
