<p>[QUOTE="dougsmit, post: 1948056, member: 19463"]As a lifetime photo hobbyist, I have a number of lenses laying around. If anyone is planning to enter the market for a 'decent macro lens' I would like to make a couple suggestions. I have found the image quality between the middle and the high end a lot less significant to the final results than a few factors that many people overlook. </p><p><br /></p><p>To me, the significant factor when shooting really small things is working distance. Many lenses will focus much closer than it is practical for everyday use. For coins I really recommend a long focal length macro. If you camera is the 'crop' version with a factor of 1.5 (Nikon) or 1.6 (Canon) the shortest lens I find reasonable is 100mm. 150mm would be better. If you have a full frame sensor camera, the 150mm becomes the minimum. I do not recommend 50-60mm macro lenses unless you only shoot tetradrachm size items. My 100mm Canon macro used with a set of Kenko extension tubes will fill the frame with my smallest coins and still allow about 4 inches of space between the front of the lens and the coin. I need this space to allow light to fall on the coin from the angle I want. I wish I had bought the 150mm Sigma macro instead so I could have the same spacing when using my Canon 5DmkII full frame camera. When planning those dinner plate tetartemorions, keep this in mind.[/QUOTE]</p><p><br /></p>
