For this purpose each the weight comes on the adapter Novoflex NEX / MIN-MC-MD of 89g.
Thus the lens mount is not too much load and could cause damage, I have gained this tripod collar for the adapter.
This is very well made and leaves me with a trustworthy impression. The weight of NEX-7 and the respective lens of up to 1.2 kg then transmits this tripod socket. It looks very old fashioned, because the body of the camera is not exactly known size.
These old Minolta treasures I can "shoot" good pictures. Due to the manual focus is in my opinion the photographing is decelerated and I can enjoy it longer.
The tripod mount is not cheap, but reasonably priced in terms of material and careful processing.
In this respect, I can recommend buying without limitation.
