I got small bits of info about the upcoming Leica 25mm f/1.4 Micro Four Thirds lens. The lens has the same diameter as the current 20mm f/1.7 pancake which is 63mm. And the length opf the lens is 54,5mm. On the picture on top you can see a comparison with other lenses. The new Leica is 1cm shorter than the current only Leica m43 lens, the The Panasonic 45mm macrolens. The big lens is the Four Thirds 25mm Leica which uses the 43 to m43 adapter. The camera is the old nice Panasonic GF1.
There is one more info I got that need to be double checked with other sources. One source “heard” that the new Leica will be cheaper than the rumored 700-800 dollar/Euro price range. Let’s hope this is true because if the lens costs around 500-600 dollars/Euro (and the image quality is top notch) I am sure it will sell like hotcakes! Reminder, the “old” Four Thirds 25mm f/1.4 had a price tag of $1100 dollars/Euro. As you know that lens has been discontinued and you can still find some Four Thirds 25mm lenses on eBay (Click here).
P.S.: Someone can send me a picture of the lens? Thanks!
