I am overjoyed that the 'Manual' lens works so well on a new DSLR. I found the prospect of rephotographing my entire
collection manual focusing through the eyepiece too daunting, so I bought the AF son, so to speak, of this same lens, the AF 60mm f.2.8, and I rejoiced in Cleisthenes getting the 55mm f.2.8. I am so glad that it arrived promptly; the postage halfway around the globe is not so bad as you'd think!
Congratulations on your photo. All you need is some reflected light on the dark edge;
Doug Smith, who soon will have posted a new page on coin photography, is quite right that aluminum foil works well. I wish I could claim that my first DSLR photo was as
good as yours.
