What close-up and macro lenses are recommended?
Multi-element achromatic lenses are preferred. See this post by Fred Moore for comparison of single-element and multi-element lenses. The following close-up lenses got positive comments: The Olympus B-Macro (a.k.a MCON-40). A 2-element, +2.5 dioptre macro lens with a 55mm thread. The Olympus MCON-35. A 2-element, +3 dioptre multi-coated macro lens. Requires a step-up to 62mm. The Nikon 4T (52mm thread) and 6T (62mm thread). Good, inexpensive, 2-element, +2.9 dioptre lenses. Some samples here and here. The Raynox DCR-150 (+4.8 dioptre) and DCR-250 (+8 dioptre). 3-element lenses with a 43mm thread (universal adapter included). Also available together as the CM-2000 Macro Explorer set. Will cause vignetting at zoom settings below 4X. See samples. For samples and comparisons of various close-up lenses, see the following: – A comparison between Nikon 6T and Sigma macro lens by David DSM, – Ching-Kuang Shenes post comparing a Nikon 6T to a single-element lens.
