I'd imagine the old Minolta 35mm f2 would produce better images, and be around the same price.
There's a browser add in called Keepa that can track Amazon prices and show prices in other regions.
Op Im curious how do you come across deals on amazon.de do you search there as well or have something set up like alerts ?
AFAIK this lens is not available in FE mount, but yes, good for A mount users or those who also plan to buy the LE-EA5 + compatible camera.
Looks like a good price but be aware it is for the old Sony A mount not the currently used E Mount so just make sure it fits your camera
