G. Pierre, I would like to see some tests done at longer distances - landscape vistas, distant trees, mountains, whatever, which might reveal any softness in the cornes and image side borders. This is where the weakness has been shown previously with the 25/2 even stopped down.
cyra, Lloyds does have at least one test of the 25/2 at a much further distance than 1-2m that showed the weak corners stopped down if I recall (I no longer subscribe). http://www.digitalcamaralens.com/Html/Objetivos/Zeiss/Distagon%2025%202%20ZE/Distagon%2025%202%20Coments.htm
Well, They are already assembled four of the 10 photo-tests that I did the past Monday. I no cut a crop on the central area becasue no are difference between all the AF modes.
The first three photos have an exchange images mousing over them, the fourth you must to select the focus mode in the down texts.
The method is always the same for all: the first with live view focus and that is exchanged with the MF ring full of top-infinity.
regards Hi G. Pierre, I'm looking forward to the rest of the tests and hope to see some distant detail at the borders or corners. These you have posted look great but, of course, all the border/ corner detail is at a very close distance. Well, I just change the Zeiss 25/2 for a Cannon 24-70, before return it I´ll make another sample focusing the sky or undergronud that in a normal photo of landscape i think that is inusual, is the only way for put the corner in infinite. Until now I´d centered in make the focus at infinite in conditions of the middle horizon.
regards
There are a number of situations in actual shooting where distant detail can show up in the corners. Waynes seascape and pier shot are examples where the bottom corners are at a very far distance. Mountains shot from a lower position (or anything similar) is another where you can easily end up with important detail at the upper borders. The test for this is pretty easy with your distant mountain scene from the high vantage point as all you have to do is tilt the camera down until the mountains are framed at the top edge and go into the corners.
