Tokina 10-17mm

The Tokina 10-17mm fisheye zoom is becoming an increasingly popular lens in underwater photography. Even Alex has one! It is not straight forward to mount a filter on this lens because unfortunately it does not have a rear filter mount. However it is easy to mount a Magic Filter on this lens, although the size of filter you require depends on whether your Tokina lens is designed for Nikon or Canon cameras.

Nikon
Fitting a Magic Filter to a Nikon mount Tokina 10-17mm is very simple. All you need is a square of filter cut to 23x23mm, which can be secured to the rear of the lens by taping the corners onto the large plastic surround to the rear filter element:

23x23mm is smaller than any of the existing sizes of Magic Filter - and therefore if you already have one of our filters you can easily cut it down to fit the Tokina. If you want to buy a filter specifically for this lens we suggest that you buy a 50x50mm square that we sell for compact cameras (original Magic - CM; and GreenWater Magic GWCM) - as each sheet will give you four filters for the Tokina, which should keep you going for some time.

Canon
Fitting a Magic Filter to a Canon mount Tokina 10-17mm is a bit more complicated because the rear of the lens does not have the conveniently large plastic surround. For the Canon lens you will need to cut a large circle of filter 35mm in diameter and then leave small 5mm tabs sticking out to enable you to tape it in place:



The filter size that you will need to do this is the 50x50mm square that we sell for compact cameras (original Magic - CM; and GreenWater Magic GWCM). Thank you to Michael Pak for the photos.

And once you have done all this you are ready to get shooting. The Tokina 10-17mm is a fantastic lens for underwater photography (photo by Michael Pak with Tokina 10-17mm, Canon 400D and Magic Filter):
