Purchasing a dedicated optical macro is actually quite substantial (at least 4 or 500 to have good stuff) amateur photographers (including myself) can try these magnifiers studding to approach the world of macro. They have the effect of reducing the minimum focus of your goal. For example, roughly ... on my obj. MAP 18-105 with a minimum of 45 cm between the lens and the subject photographed with a windshield close-up four, I could get close to about 12 cm First positive point, these are studding as filters, so you keep auto-focus, although it is easier to do its MAP yourself by disabling the AF target. Secondly ... you can combine the studding to get a very big merger ... but you quickly come to a visual mush if you accumulate four for example. The 10 is only to be used and the four for me (my favorite). The 1 and 2 may be combined together for a result already very convincing, as long as you have plenty of light and especially a tripod but this combination can make significant distortions at the edge of the image (important and blur depth of field ... almost zero at the same time it is quite normal to macro, since this is not what we're looking for). Personally, I only use these studding one at a time, depending on what I want to photograph. To summarize, these bonnets are very effective for those who want to make the macro tripod and on objects (or food) fixed. So you have to have time, tripod, light ... Outside, and mobile, I have not tried, but I have serious doubts :-) While waiting to put money aside for a good purpose dedicated "macro" is a good investment that will allow some shots already very nice, but that inevitably leave a feeling of frustration, as very limited in the possibilities ... but to get the hand is frankly very nice :-)
