<p>[QUOTE=&quot;dougsmit, post: 2627082, member: 19463&quot;]I suppose you could say I wasted $18.30 because what I gained really does not improve my photos nearly as much as buying better coins would but I had to try it.&nbsp; I bought a second set of automatic Canon mount extension tubes.&nbsp; Used on my 24x36mm sensor Canon 5D mkII and Canon 100mm macro lens, the total of six tubes (two sets of three) allows filling the frame with a subject about 8x12mm.&nbsp; The closest I have is this 8x10mm 0.34g coin.&nbsp; Previously I could shoot with just one set of tubes or even just with the bare lens which stops at 1:1 (therefore 24x36mm).&nbsp; I can not show the full size image because of limits on Coin Talk and the tiny reduction here (1620x1080 pixels reduced from 8387x5591) shows no quality upgrade from the cropped ones.&nbsp;&nbsp; There might be a difference if I made a really big print but just how many 20x30&quot; prints of 8x10mm coins do I need?&nbsp; Not enough to pay off the $18.30 toy but we don&#039;t buy this stuff for financial gain.&nbsp; The image below is a merge of one horizontal of the obverse and a vertical of the reverse and enough blank black to fill the gaps.&nbsp; The lens is past its best at this magnification.&nbsp; Canon makes a lens for this sort of work but my having trouble justifying the $18.30 makes a $1049 lens out of the question. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie76" alt=":playful:" unselectable="on" unselectable="on" />&nbsp; Those who do not already have a set of tubes might want to consider them.&nbsp; My old set is Kenko which is made better than the new eBay specials (there are several brands - I selected the ones which included a tripod socket on the tubes).&nbsp; The Kenko have lasted for years; the new ones????</p><p><br /></p><p>[ATTACH=full]577327[/ATTACH] </p><p><br /></p><p>CILICIA.
