The only Micro Four Thirds lens currently carrying the "Leica blessings" is the 45mm f2.8 macro MegaOIS, and that very lens was just reviewed at Photozone, a critically acclaimed lens review website. As usual, we won't spoil their findings here.
Yes, we have the first review of the mysterious Panasonic + Leica collaboration lens, the 45mm f2.8 Macro with MegaOIS. The review is by dpreview.com! They have five pages of goodies, with the verdict and recommendation "badge" on the last page. There they also have a gallery of real-world pictures taken with it.
This is not a full-review, but this is the first real world sighting of the promising Panasonic 45mm f2.8 lens. Qeusabesde has published their first look on the lens, complete with full resolution JPEG images for our enjoyment and evaluation!
The pictures were taken with the new M43rds darling, the GF1.
