You hold down the menu button and turn the camera on, firmware virsion is displayed on the back LCD

no suggestion for the CPL though

EDIT: sorry that should read version

First the easy one and that's the firmware.
Hold down the MENU button and power on the camera, you will see the firmware version on your screen.

Now the filter, that's quite a problem, one reason to get B+W filters
Since the filter turns you can't get a good grip, so move a rubber band around the filter that does not turn it will give you better grip.
If that does not help put it in the freezer, the metal filter will shrink more than the plastic lens making it easier to loosen it.
If that does not help get these link
If that does not help then I don't know either, camera repair shop is then an option.

some good tricks to use there stefan, i've had the same problem before but when i had it it was attached to a uv filter, (uv's stay on the lenses permenantly) so all i did was get a small flat head screw driver put it into the groove on the filter and put a little pressure on to loosen it, at worse i had a little scratch on the outer ring of the uv filter. not ideal but it worked. this actually leads me to another question which i will make a new thread on so as not to interfere with this one.

Glover with normal filter use your shoe
I'm serious here, place the sole of the shoe on top of the filter apply some pressure and turn the shoe, with some luck the rubber of the sole catch the filter and turns it so off.
You can't use it with a polarizer because that filter turns in the filter mount.

And here is another tip, lasso a electrical-cord around the filter and use that to turn it.
Most of the time you can't get it loose with your hands because you apply uneven pressure on the filter so basically you make it oval and therefore making it even more stuck then it really is, with a cord the pressure is even, keeping the filter round and that should help quite a bit.

sorry i meant the polarizer was attached to the uv filter, which was when i used the screw driver to get the polarizer off it, but again, great tips i like it

The harder you grip a filter, the more you distort its shape and the more it locks onto the lens.

If you press the filter into the palm of your hand, you apply pressure evenly and rotating your hand might release the filter. It will be covered with grease from your hand, but that's better than a filter jammed in position.

A piece of mouse mat might do very well instead, but I've onlt just thought of that and haven't put it to the test.
Best regards, John

I use a kitchen rubber glove - gives excellent grip to remove stuck filters.

You can buy filter wrenches. They are low cost and may be worth a try.
Here is a link: -

Also you may try an electrical 'tie wrap'

Good luck getting it off.

Suppose I'm luck in a way - I have dodgy hands so always tend to screw things up and then slacken off fractionally , and I always take my time when changing lenses etc .

I tend to keep a thin latex glove in my bag as well.

Thanks folks for your input,i think the problem is metal thread on filter and plastic thread on lens not a good combination at all .Not sure about putting lens in the freezer ,the metal ring would only get tighter as the metal would contract i would've though,but if all else fails .

I should have guessed this would happen because it was always a wee bit sticky to screw on ,no one to blame but myself
Thanks

Like you said if all else fails that's on option, wait till a Tuesday and I might have an answer for you if it truly works or not.

About the metal ring getting tighter is not true, like you said it shrinks so the diameter is getting very slightly smaller, it could be just enough to get it loose.

I'd probably get my local camera shop guy to have a go for me. Obviously I'd buy a few bits and bobs so it was worth his while!

I have some think rubber matting - full of holes but an excellent grip. You can get it for use is the kitchen in 150mm squares or a lot cheaper if you buy http://www.trend-uk.com/en/UK/product/NS_MAT_A/3/265/router_non_slip_mat_610mm_x... The picture is a little misleading as that is folded up several times.

Place a piece across the filter and with your finger widely spread so your grip is all around apply enough pressure to make the matting stick and ease it round.

Don't grip too tight or you will distort the filter (temporarily) and it will not shift - a good widespread grip is what you need - or as suggested use a ty-wrap over the matting - one on each filter and move in opposite directions.


OR


A quick trip down the A939 with it and I'll try for you - provided you don't mind salmon scales and slime over the lens!

If you have a traveller's universal sink plug (actually a circular bit of rubber) they work very well. Basically anything that helps with grip but doesn't distort the filter will help.
