Do I need a lens support for a Tamron 70-300mm on a tripod, or is my tripod head the real issue?

I’m using a Tamron 70-300mm f/4.5-6.3 Di III RXD on a Sony A7 IV. When the lens is zoomed to 300mm and the camera is mounted to my tripod by the camera body, the setup droops slightly, making framing difficult and making me worry about the mount/screw.
I looked at a few options:
- rotating collars n- generic support collars
- rail-style long-lens supports like the Andoer L200
- building a custom rail support
My tripods are a Joby Gorillapod 3K kit and a Vanguard Vesta 203 AGH.
For a lens like this, what’s the correct way to support it on a tripod? Is a rail support the best solution, or does the droop indicate that my tripod head/tripod is the main problem?

The Andoer L200 should work with an L bracket. The camera to rail attachment is just two arca swiss clamps screwed together. The top one should be able to be reindexed at 90˚.
Hejnar Photo makes the components as kits or individual modular pieces which you can combine to suit; Chris makes very good quality kit. I'm not sure which screw "feels like it's about to break", but as long as it's not the camera socket/screw you could just use a long arca swiss rail to center the weight (w/o the front support).
But IMO, the main issue is your tripod/head. The lens does not have a tripod foot, which means it is intended/designed to be supported by the camera body. If the tripod head is drooping under that load it is probably inadequate; marginal at best. Centering the load with something like the L200 is a possible workaround, but what about other situations which put the load off-center (e.g. macro)?

The main problem is most likely the tripod head/tripod, not the lens mount. A 70-300mm lens without a tripod foot is generally meant to be supported by the camera body, so if the setup droops when zoomed out, your head is likely being overworked or the tripod is flexing.
A long-lens rail support such as the Andoer L200 can help by shifting weight and adding support under the lens, and it should work with Arca-style parts. A long Arca rail alone may also help center the load even without a front support.
But support hardware won’t fully fix an inadequate head or flexible tripod. For better stability:
- avoid extending the center column
- keep leg extension minimal
- extend the thickest leg sections first
So yes, a rail support is a valid option, but the more important fix is a stronger tripod/head if droop is happening with this lens.
