I'm not sure what the model of the actual tripod is but it's big. The head is an R.3 which should easily hold a 4x5 and would probably do well with an 8x10. With just the legs extended it reaches to around 6' and there's still 2' of center column travel. This one is well used but I've had Gitzo's for the past 10 years and they've always been absolutely stellar as far as durability is concerned. One of the legs is missing the little knob on the leg angle part but you can just as easily move the stop without the knob. Otherwise it's well used but everything works great. If you're looking for a bombproof tripod that's outlived one owner and is ready for the next this is it. $200 plus shipping. Will not ship overseas.
