Tamron offers this great lense with a range of focal length of 100-400mm.
Many photographers enjoy this lense but miss an affordable tripod mount.
I have designed a new tripod mount specifically for this lense! It has a unique design which accomodates the lock switch which remains fully functional!
The base is almost 10cm long and is arca-swiss compatible.
Additionally, the base is equipped with a 1/4'' thread for all other tripods.
It offers great stability for all scenarios and is very light weight (60g):
Thanks to its long base and support you can even attach your heavy DSLR to the lense!
