I purchased the following items but plan on returning a few depending on whether or not it fits my needs:
- Gitzo 1545T traveler tripod
- Gitzo 2545T traveler tripod
- RRS BH-30 with compact-size lever release
- RRS BH-40 with full-size lever release
My goal is to use a combination of the above tripod/ball head for backpacking and hiking locally, using the 5D Mark III and 16-35 IS and 70-200 f2.8 II. Initially, I was also considering use with the 100-400 II but will use my Gitzo systematic tripod and BH-55 combo for that lens instead, when needed.
I'll probably keep the larger 2545 since the folded length isn't all that much over the 1545, but I gain a bit more stability with the 70-200.
The next question is BH-30 vs. BH-40. I know that the BH-30 will allow the tripod legs to fold completely but would rather have the BH-40 for extra stability. However, I am wondering how much the tripod legs spread when the BH-40 is mounted. Another viable option is to not have the ball head mounted on the tripod when backpacking, which I am also considering.
