I'm looking for a travel tripod to be used with my 5DIII and the heaviest lens in my future would be 100-400. My other gear is listed in my signature. Would either of these two hold up? I'm not looking for something for long exposures, just something I can bring along to the beach or the park to help me steady the camera. I have a hard time hand holding heavy gear. I do have a more substantial tripod already. I just don't always feel like lugging it around with me. The two most important factors for me are small folded size and weight (well, price, too).
I also worry about the ballheads included. Not sure they are up to the weight of my gear. Is it okay to swap ballheads on something like this? I have the Acratech GP that I could swap out. I like it and it's lightweight. Would that help?
After researching travel tripods, these were the two standouts in my price range. If they aren't up to the task, I'm willing to forget about a travel tripod and just use my Induro CT-213. I don't want to waste my money unnecessarily (that could be used towards that 100-400!). I'd appreciate your thoughts on this.
