<p>[QUOTE="EyeEatWheaties, post: 1053485, member: 26972"]Exactly, which why I created this thread. I wanted to hear from guys who shoot coins, not mamby pambies who shoot flowers and bugs and then go on to say how well the lens does a portrait. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /></p><p><br /></p><p>There is some very good information in here, thank you to everyone who contributed. I am very grateful to be able to use y'all's trials and tribulations hopefully saving me the grief of second guessing after a purchase. Thank you.</p><p><br /></p><p>I like the idea of buying the canon lens, but I worry about melting the camera. I move lights around a lot. Leadfoot, the 180 obviously didn't impress you since it appears that you thought you were upgrading to it, but yet moved on to another. So to further justify, you get what you pay for, I am convinced that the Sigma 150mm will deliver. I'll melt the 100mm and the Tamron 180 will leave me wondering if I should have doubled down for the Canon 180mm macro. (that lens is stupid money IMO)</p><p><br /></p><p>On another forum, I posed the same question. I got what I believe is one of the most superior/perfect examples I have seen of a copper cent yet shot with the Canon 100mm and camera with same sensor size as mine but with 12.1 mp vs 10.1 on mine and a 20% deeper pixel density (3.7 vs 3.1) I need to reiterate that I only shoot copper.</p><p><br /></p><p>Anyways, I think it will be appreciated to post the same pics for comparison and side by side study. OK below. the 1910 is from a Canon 100mm Macro on a 450D (not sure if the coin was slabbed) - The other coins are my shots from my current set up.
