As for "wide macros" I think that's an oxymoron.
For that average Joe consumer yes,but Bjørn Rørslett would beg to differ....these aren't intended for infinity shots.
"The unique and elusive Macro-Nikkor range comprises 4 lenses made for the Nikon Multiphot, an advanced photomacrographic device targeted at the scientific lab segment. They are largely unknown to the general public, and people get confused by Nikon designating them as "Macro" lenses (which they in fact are). After all, aren't the familiar Micro-Nikkors also "macro" lenses? Nikon's terminology is literally correct, as the Macro-Nikkors only provide larger than life-size (1:1) magnification in contrast to the Micro-Nikkors, which ends their focusing range at 1:1 or 1:2 and can focus to infinity."
The widest is the Macro-Nikkor 19mm f2.8 and there is also the Macro-Nikkor 35mm f4.5...
Zuiko also produced a photomacrographic lens the Zuiko 20mm f3.5 Macro optimized to produce around 8-10:1 images...
Canon produced a photomacrographic lens the Canon 20mm f3.5.Optically it's not up to the quality of the Zuiko 20mm...
Nikon also produced the Ultra-Micro Nikkor 28mm f1.8.Originating from a series of industrial lenses optimised for extreme sharpness (up to 1.200 lines/mm resolution!)
Novoflex produced the 35mm f3.5 Noflexar.The 35 Noflexar was offered in various mounts, most are found today in Exacta mount while F-mount versions are rare. The rear section protrudes into the camera throat and on some bodies can jam the reflex mirror (no issues on D200 and Fuji S3, though).
Olympus also produced a comprehensive range of true macro lenses, i.e. lenses that is designed for larger-than-lifesize work and thus there is no need for reversing them for macro photography.The widest in the line is the 38mm f2.8 Macro.This lens is multi-coated, but strong flare still can be an issue with it.
