Thank you for your support! Not sure why longer focal lengths were not mentioned in the article. Just to correct a one misconseption here: A7R sure lacks an AA-filter, but it still has a thick glasssheet on top of the sensor as revealed in lensesrentals. Basically this glass is usead to equalize incident ray angle differences between differerent A7-models.

Because of this, Loxia or any other lens behaves the same regardless of used A7-camera. Only possible differences are caused by a different pixelsize and microlenses on top of the pixels.
