Hello community,

I've purchased a used 50-150 and it should be arriving in a few days. I'm looking for 50-150 owners who are very familiar with the lens to give me some tips on testing and what to look for (first time buying used)

From research it looks like I should be checking 2 things with this particular lens (outside of checking the glass)

1. Zoom ring noise when zooming

2. Mounting issues when the lens is mounted

Also...

a) Does anyone know where I can buy the tripod extension for the lens? Google hasn't been helpful and it doesn't look like samsungparts.com is still carrying it.

See my other reply.  Really need to search by the parts number to get anything at all and when you do all you get is samsungparts and the Australian site I linked.

b) I've read you can change the focus distance to improve focusing? How do I go about doing this?

You can limit the focus range which ensures it spends no time looking for focus outside of that range.

c) There also seems to be a switch (full, custom..) under the AF/MF that I'm unfamiliar with on the lens.

This is exactly your answer to part b).  "Full" is normal lens operation, if you set the switch to "set" you can set a range of focus on the screen (though I wish it were a bit more fine grained), putting the switch to "custom" makes the lens limit the possible focus distances to the range you set in "set" mode.

Thanks!
