For those interested, I tried to compare the "old" Made in Japan version with the "new" Assembled in Vietnam version.
As the weather is pretty dull outside, I tried it on flowers, ie. closeups.
I set the K-7 on a tripod, set the camera to manual focusing and tried my best to set the focusing point to the same spot which is particular sensitive on closeups. I used Liveview in 8x mag to check the focusing.
Here is the result:
K-7, Voigtlander 125, f/8, 10s, 100iso
K-7, DA*300, f/7.1, 3s, 100iso
On the left side is the "old" made in Japan version, on the right side, the "new" assembled in Vietnam version.
