24mm lenses for your A7 and A7r

The NEX-VG900 camera and the lenses. Image courtesy David.

With only two 35mm and 55mm primes coming with the A7 and A7r these are some possible third party lens options for the 24mm focal length. I would be glad if you could share test and impression of these lenses used on a Leica or Sony Vg900 camera. It could be useful for all future A7/A7r camera owners. Thanks!

The list contains lenses deisgned for a mirrorles ssystem (not for DSLR systems):. This because I guess size matters if you buy the A7 :)
