Raynox DCR-250

I borrowed this from a friend. It is different from extension tube where you put the tube between camera body and lens. We use Raynox DCR-250 in similar manner to filter, so we put it in front of the lens. It comes with a clip on adapter, so we can mount it on any lens with filter size between 52mm and 67mm. If you want to use it on lens with filter size less then 52mm, you can use a step up ring.

I tried to put the Raynox DCR-250 on my Sigma 70-300mm f4-5.6 APO DG. When I use the lens at 300mm and 1:2 macro, the distance between the lens and object is around 50cm, but with Raynox DCR-250 mounted, the distance becomes 5-6 cm only.

Here are some shots taken using the combo.
