Filter holder question

I own both the Tamron 15-30 and the 24-70. Does anyone know of a filter holder that would hold a polarizer for both lenses?

Answering the question you did not ask - are both lenses suited to use with a pol? on 4:3 format - just about yes - on larger formats - especially 24 x 36 - even the 24-70 can have some drawbacks at 24mm - and the 15-30 can introduce significant problems.


Getting slightly technical polarised light (when it is present) falls off very quickly outside and angle of view roughly equivalent to the horizontal angle of view of a 35mm lens on 24x36 format - and then only at 90 degrees to the light source.

This is not to say you cannot use a pol with a wider angle lens - just that the chance of getting an even pol effect across the entire image (what many are aiming for) becomes nil.

One way to economise on the cost of pols is to get one for your largest filter thread is also use it on step down rings on smaller filter thread lenses.

For landscapes, not been able to use the lens hood is usually not a serious issue as the best pol effect is usually at 90 degrees to the sun.
If you use a tripod and shutter delay you can hold a piece of black card at the side of the lens to shade it from sunlight.

Digressing slightly when you see video cameras for wildlife being used they often have a large shade above the lens - to reduce light from the sky to achieve better contrast in whatever is being recorded. Photographers tend to pay often serious money for grad ND's to obtain a similar effect.

Slot in filter holders are usually compatible with a range of lens sizes - you buy an adaptor that fixes the filter holder to the lens. The adaptors come in various thread sizes to suit different lenses. Look on the front of each lens and you should see the size in mm of the filter thread. With luck both will be the same allowing you to buy just the one adaptor.

The 15-30 lens is likely to need particular consideration. A lens this wide is likely to cause vignetting when used with a filter system (where the edges of the filter holder - or its shadow - become visible in the corners of the frame). Most slot in filter systems of repute offer a wide angle adaptor (this can be used on other lenses too). Depending on the system you have you may need to look into this.

The points Len makes about polarisers are worthy of note. At very wide focal lengths you will often get an irregular polarisation effect across the frame which looks unnatural.

Does the tamron have a front filter thread?

Also, you need to be VERY careful with polarisers on wide angle lenses, as the amount of polarization will fall off across the frame, and this can ruin the picture. You can just about get away with it if there is no sky visible in the frame - great for shooting in woodlands, but not wide open vistas.
