The Sigma (1,5 or 1,6 diopter) can also be found in 52mm and 62mm (and replace Nikon 3T and 4T). The 58mm was offered as a specific CU for their 70-300mm lens. Fascinating. The famous Achromatic Close-Up Lens Page (http://www.angelfire.com/ca/erker/closeups.html) mentions only the 58mm version.

- Original Message - From: Andre Langevin [EMAIL PROTECTED] I used the Nikon Close-up lenses for quite some time. They really do give very good results. Christian Indeed, and easily obtained, even on eBay. But made for 52mm filter size, so a step-up is necessary. No big deal.

I personally would not bother with these lenses. Buy a bellows and some high quality 6 element enlarging lenses ( Rodagons, Componons, etc) and you will be jammin'. Beauty part is these enlarging lenses are dirt cheap used on ebay now due to the many people abandoning conventional darkrooms..

While bellows/enlarging lens may not be as cheap as a closeup lens, the achromatic ones are not $5-$15 and the bellows/enlarging lenses are cheaper than dedicated macro lenses.Especially if you want multiple focal lengths Minolta achromatic close-up lens, on eBay, can be found at that
