As an architecture and interior photographer (as well as a lens and camera reviewer) a tripod is an essential item and I'm always looking for the ideal model. I like Gitzo tripods but having just one isn't really an option; they're not versatile enough to cover the multitude of likely situations encountered. Like lenses you really need to have several (see here for an article about how to select the most appropriate Gitzo), so I was pleasantly surprised to See Gitzo introduce an Ocean version of the new Systematic models. These are a vast improvement on the originals and the Ocean version using steel instead of mag-alloy and improved leg joint seals promises to be their most rugged yet. I like the 4-series best, they have substantially larger leg tubes than the 3-series, while offering more load carrying capability without having the bulk and weight of the larger diameter tubing of the 5-series. I hope to have one of the new models soon for testing.
