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 ...

Glover with normal filter use your shoe :wink: 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 fil...

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 ...

You can buy filter wrenches. They are low cost and may be worth a try. Here is a link: - http://www.crookedimaging.co.uk/index.php?cPath=26_37 Also you may try an electrical 'tie wrap' Good luck getting it off. Paul

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_1220mm_.html The picture is a little misleading as that is fold...

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. K.

Lens Rattle?
I asked SRS about this with another lens and they said that sometimes you get a small amount of movement within the lens. The lens in question produces superb results and so I don't worry (much). Try taking hold of the filter ring and try to waggle the lens, you may find some lateral movement. ...

Lens hood and filter combination - how do I set it up properly?
I have recently invested in a rubber lens hood for my 18-55mm lens and want to use it in combination with my Hoya Polarizing filter and UV filter - I have attached the hood first with the filters sitting inside the hood... is this the right way to do it - or should I put the hood on after the filter...

Lens hood and filter combination - how do I set it up properly?
Do not use the two filters together, you are just introducing more reflective surfaces and a possible degradation of image quality. The sole point of a UV filter is to reduce aerial haze, only seen with telephoto lenses in certain circumstances. I'm afraid that it is a pretty pointless thing to ...

Lens hood and filter combination - how do I set it up properly?
Can I just chip in that the Pentax hoods sound ideal but they seem so expensive. About £27 each - just for a cylindrical bit of plastic.

Can I just chip in that the Pentax hoods sound ideal but they seem so expensive. About £27 each - just for a cylindrical bit of plastic. They are the right tool for the job, so if you want the best result the answer is clear. Yes, they seem expensive, but they are efficient.

Lens hood and filter combination - how do I set it up properly?
Just another thought about your rubber hood, even without seeing it I'm pretty sure it will be for a standard lens and will cause vignetting on its own at focal lenghts below 30mm.

Is this a colour or black and white image? If black and white then a colour filter the same colour as the stain will remove it. If colour, try looking at the individual colour channels in Photoshop. In RGB mode look in turn at the red green and blue channels to see if the colour of the stain d...

The 'blobs' at top left of your photo's is sensor contamination. My recommendation is to get yourself an Arctic Butterfly from Visible Dust. IMHO it's the best sensor cleaner there is. It's all I ever use. I've never wet cleaned my sensors in 2 - 3 years. Using a blower to clean dust from a senso...
