Sony A7 system - search for a wide angle landscape lens

[Herbc]

While I have not done extensive tests, the Leica 28mm R lens has produced some really fine landscape photos handheld with the A7R, excellent sharpness edge to edge.  I  have the 24mm but have not tested it yet.
These are really good lenses, and have none of the limitations modern AF lenses pose in infinity focusing.

I agree that the Leica 28mm 2.8 Elmarit-R is a very good lens on the a7. Here's a short resolution test of it against the Leica 28mm f/2.8 Elmarit-M ASPH and the  Nikon 28mm f/1.4 D on the a7II:

I tested the v1 version of the Leica R lens. The v2 version is supposed to be better, but is too rich for my blood.

Short summary of the test results: don't buy the Elmarit-M  for use on the a7.

Thanks for the post.

I wonder have you tried the newer Nikon 28 1.8 G ?
When I switched over to Nikon I got the 14-24 for very wide stuff and bought the 28 as a lightweight travel lens for fishing photography and I'm very impressed, especially with the extreme corners.
IMHO, it's an amazing lens for the money.

No, I am not good with a 28mm lens, prefer 24mm.

I was in Batis lens presentation few days ago.
Both are marvellous but both has focus-by-wire system and no hard stop.
OLED display scale is pretty neat, Zeiss representative says that lens somehow re-calculate DOF values for different camerasa (like A7s and A7r with much denser sensel) but in short time we unable to check it carefully.
Also i made a quick comparison with Sony-Zeiss 2/24 from a-mount - really good lens.
And i found that on a7R Batis is sharper on edges and corners towards F5 or so on. Distortion is very low, flare resistance is exceptional (a biggest flaw of the 2/24 Distagon is red flare over the sun's opposite side of the image), CA is pretty well controlled too.

And it twice as lighter 'cause they use more plastics and no lens-adapter.
Lens-shade is also plastic and looks very cheap (Zeiss confirmed it;-)

There some RAWs 24 and 25 side by side

There is close-focus "brick wall" test files https://yadi.sk/d/QP454qA4hToiV

There is some out-of-focus and central area sharpness side-by-side

And there is quick hand-held comparison wih high-contrast wide-angle scene - for CA and spherochromatism.
