Adapter ring for filters

Hi,

I am looking at getting a filter and adapter ring for my 58mm lens (18-55 and 75-300), however as the focusing ring rotates will this work?
Does the actual filter housing rotate so that it can be kept straight?

The focus ring turning means nothing. Does the front element (piece of glass) on the lens rotate during focussing? If not, you have an internal-focus lens and the filter will not rotate.

In my experience you can rotate filters after you focus....the filter adapter isn't screwed on viciously tight...there is room to rotate.

Check out the Cokin filter system or similar. They are square and drop into a filter housing as you describe. This housing allows filter stacking and also is free to rotate on the adapter ring which is screwed to the lens. If your front lens element rotates then the adapter ring will also but not the housing or filter. Their kits come with varying filter size adapter rings to fit different lens threads.

CP filters often rotate on their own built in adapter ring. Never screw the filters on too tight as they can be a bugger to get back off.

The only issue with it rotating is if you are using a polarizer. Just means you have to readjust the polarizer for maximum effect.

I agree with nikon jon. Gradual filters are also ones to watch.

Most CP filters rotate and can be adjusted after you adjust the focal length.

It depends on the type of filter. However, if your lens is not IF (Internal Focus), you cannot use a polarizer or grad filter until focus is achieved because external focusing lenses turn the front element and filter threads as they focus. Look into Cokin or Lee filters.

I do not use them all that often now but I have quite an extensive set of Cokin filters. Most of the effect ones I used for film particular more for black and white but I get the same or better results in PP.

I also have better quality CP filters however I do find the cokin square filters useful to hold in front of a speedlite to give certain colour casts.

Some products are set off with a coloured light.
