For the past few years, I've been using my Gitzo Series 1 Mountaineer as my primary tripod. It served me well when my primary camera body was the Fujifilm X-T2, X-T3 and X-H1. Once I bought the GFX 50S to use alongside my X-H1, I became acutely aware of the tripod's shortcomings. The Gitzo Mountaineer Series 1 GT1542 is an excellent tripod. Combined with the lightweight Arca-Swiss p0 head, the tripod weighed in at just under 3 lbs and featured a very slim profile when folded down. The 25mm max leg diameter contributed to this slim profile, and while it works well with entry-level DSLRs and mirrorless camera bodies, the slim legs are just a bit too thin for a heavier, professional level body like the GFX 50S. Most people with a larger, heavier camera would be perfectly served with any Gitzo Series 1 tripod, as they only need it for single shots in adequate lighting. In my case, I use it primarily for landscape photography, astrophotography, night photography, etc... situations that require long exposures and/or multiple exposures for stacking, exposure blending or panoramas. This requires greater demands on my tripod as any movement between shots can ruin an exposure. It becomes difficult, if not impossible, to work with multiple, misaligned exposures in post-processing, thus a lighter-weight tripod can cause problems as any flexing will result in misalignment. While I haven't gotten rid of my Series 1 Gitzo, I recently bought a Gitzo GT3542 Series 3 Mountaineer.
A quick comparison between two products designed mostly to perform the same function. In case you're not familiar with an L-bracket, it's function is purely to allow rotation of your camera by 90 degrees while keeping it balanced on the X axis of your tripod. This is especially important for panoramas so the camera yaws directly over the center point rather than circumnavigating it, which alters the perspective enough to make stitching the result more difficult or even impossible.
Single row panoramas have always seemed to thwart me. Either the scene was never appropriate or they wouldn't stitch for one reason or another. After getting the stuff I needed to establish the nodal point on a couple of my lenses, I decided to give it another go from Kerry Park.
First, and most importantly, know what genres of photography you enjoy the most and if that genre requires a tripod. Then, buy the largest, highest quality tripod you're willing to carry that fits in your budget. Specifically in that order; do not put budget ahead of any other aspect of the tripod. If you go too cheap, you may very well end up with a tripod that meets none of your needs when you're forced to replace it due to instability or fragility. The adage, "buy cheap, buy twice (or more)" applies here.
As much as I like Gitzo as a brand and the quality of their products, some of their stuff just isn't as good as others. Take for example their leveling base; Gitzo features a large lever for tightening a head to the base and a handle borrowed directly from their sister Manfrotto's lineup. Instead, I got the series 3 leveling base from Really Right Stuff. It's lighter, has a simpler attachment system with no silly lever and a much sleeker locking handle with, get this, a gear hook! That hook alone is almost priceless, allowing me to attach weight for stability when I'm not leveling the head, ending any need to swap back to the flat top base. Back into the box that can go.
