For the first test, I was using it handheld but for the last measurements I took, I mounted the 70-200 using the tripod ring and it was much easier (lens on tripod, not camera). Getting an estimate on my focusing distance really helped out and I will FOR SURE be using the tripod for macro shots when using the 70-200. I'll try testing out the 40/2.8 as well. That sounds like fun!
Aw yeah if you were doing it handheld then that totally makes sense you were having issues
Yeah I got my 40 2.8 on the way. I rented it twice and there was a 20% ebay bucks for beach camera so I got it. It'll end up being like $159.20 after you account for ebay bucks. Definitely will be a nice lens to have. Now I just have to decide whether to keep my 50 1.8 and 35 2.0.
Anyways enough off trackness. One other hint. With the 70-200, you can actually use the zoom ring to focus. With extension tubes the focus range is so limited it's much easier to at least get your course focus this way. Then you can do fine adjustment with the focus ring.
