Filter – Frequently Asked Questions
Filters affect the light before it hits the film or sensor – reflections gone, longer exposures, more vibrant colors. Here is the most important information about them.

Why do I need a filter?
To shape your shots directly during the shoot, instead of doing it later on the computer. Some things can only be done this way – a long exposure in daylight, for example.
What types are there?
- UV filters: originally for UV light, today mostly used as protective glass for the front lens
- ND filters: reduce the amount of light – for long exposures during the day or wide-open apertures in the sun
- Polarizing filters: remove reflections from glass and water and enhance colors
- Special filters: color, gradient, and infrared filters for creative effects
When is which one worth it?
- Bright sun: ND filter for a longer exposure time
- Water or glass in the shot: polarizing filter against reflections
- Permanent protection: leave a UV filter on the front
- Landscape with a bright sky: gradient filter
What does ND8, ND64, or ND1000 mean?
The number indicates how much the filter darkens. ND8 corresponds to about three f-stops, ND64 to about six, and ND1000 to about ten. The higher the value, the longer you can expose – for smooth water or moving clouds.
What is a gradient filter good for?
It is darker at the top and clear at the bottom. This darkens the sky without changing the foreground – the image looks more balanced and the sky doesn't blow out.
What is a slim frame?
A particularly flat housing. It prevents dark corners with wide-angle lenses – useful for focal lengths below 24 mm on full-frame.
Can I combine several filters?
Yes. But be aware that too many stacked together can cause dark corners, especially with wide-angle lenses.
Are filters also useful for filming?
Especially ND filters. With them, you keep the exposure time constant – for example, 1/50 second at 25 frames per second – even in bright daylight. This makes movements look more natural.
How do I find the right size?
The diameter is marked on the front of the lens with the Ø symbol – for example, Ø 58 mm. Only a filter with exactly this value will fit.
Are the filters new?
No, they are checked used items from well-known brands – no knock-offs. The brand is listed in the product title.
What condition are they in?
Checked and fully functional. We do not stock defective or partially defective filters at all, so you will not find a condition rating for filters. Small scratches on the glass or wear on the frame are possible, as long as they do not affect the function.
Are the filters refurbished?
No. You receive the item in checked used condition, as it is.
What if it doesn't fit?
Then send it back. You can request a return on the Returns page; regardless of that, your statutory right of withdrawal applies. Tip in advance: The correct diameter is marked on your lens.
How long does shipping take?
You can find shipping times and payment methods under Shipping and Payment.
