| 621255 | 2007-12-14 22:09:00 | Is a 0.25X macro lens stronger, or a 0.42X lens? | tarynpenny (13157) | ||
| 621256 | 2007-12-14 22:12:00 | (by the way, macro/fish eye lenses) | tarynpenny (13157) | ||
| 621257 | 2007-12-15 00:47:00 | Well.....I'm only used to thinkiing of fisheye lenses in millimetre sizes in which case 24mm, 18mm are getting wide. Are you sure you don't mean microscope? |

| 621258 | 2007-12-15 02:09:00 | A macro (en.wikipedia.org/wiki/Macro_photography) lens gives an image on the "film" which is close to the size of the object. If you are comparing "0.25X" and "0.42X" lenses, the 0.42X would give a larger image, therefore it would be "stronger". Either way, the fish must be fairly shortsighted. ;) | Graham L (2) | ||
