Coastal Optics 60mm f/4 UV-VIS-IR APO-Macro on Leica M Typ 240 / M240 [using Novoflex Nikon to M Adapter]
I’ve ordered the Novoflex NOLEMNIKNT Lens Adapter for Nikon Lens to Leica M so that I can experiment with a few lenses, in particular the Coastal Optics 60mm f/4 UV-VIS-IR APO-Macro, and perhaps the Zeiss 135mm f/2 APO-Sonnar.
The Coastal 60/4 is a multi-spectral lens with total correction of primary and secondary longitudinal chromatic aberration: no production lens can approach its level of correction; it is free of secondary chromatic errors, yielding an amazing neutrality for out of focus areas along with a very special “transparent” spectral transmission. It should prove interesting on the Leica M Typ 240, which makes accurate focusing of any lens possible with its Live View and EVF.
Also on the way are three Zeiss ZM wide angle lenses: the ZM 15/2.8 Distagon, ZM 18/4 Distagon and the ZM 21/2.8 Biogon. Reportedly the M240 has better off-center behavior so my goal here is to see what performance looks like with these three lenses. Regrettably, the 21/4.5 Biogon still has too steep a ray angle to work well on digital M bodies.
