Just bought a Hoya 52mm +10 close-up filter today. Tested it out to see how it work.
All pics taken with S602 at f/8, aperture priority, 6X zoom.
+4 close up:
Focusing distance ~ 23cm
No comments on this one, think lots of pple already have the +4.
+10 close up:
Focusing distance ~ 8cm
As you can see, there only a little softening at the edges (should not be visible for insect shots since background is completely blurred). However, 8cm seems a little too close for insect shots and focusing is very sensitive to slight shakes (I foresee many OOF pics...)
+14 close up:
Focusing distance ~ 6cm
Edges are very soft, focusing distance is way too close for insect shots. Also, any slight shake will render the pic OOF (focusing range is only abt 6cm +/- 5mm). I think this setup is totally unusable due to softening and sensitivity in focusing.
Also did a test where I place the camera 10cm in front of the monitor using the +10. In the end, the zoom required for the camera to focus is abt 81.6mm (wrt 35mm cameras).
I think with this setup, I would rather use the +4 with max zoom. Further focusing distance with greater magnification... Further more, the pincushioning is horrible.
Here's a pic of the +10 close-up filter:
Tmr would be going down to BG, I think that would be a good test of the +10 (though I foresee a lot of problems already... due to the sensitivity in focusing distance)
