looking for a good cheap tripod that will last me long, i've got a nikon d80
I do plan on getting a remote for the shutter release.
Not quite true. Hang your camera bag around/off light tripod and suddenly it's very heavy and a lot more stable.Tripods have the legs and also three possible characteristics
You can have only two of these characteristics in one tripod.
- low price
- sturdy and ridgid
- light weight
I can't speak to the Benbo...I'm sure that construction plays a big role in stability and vibration, but I've been using a Gitzo Explorer 2220, which uses the same offset concept, for many years with no stability or vibration problems. It's not a very lightweight tripod but they do make a carbon fiber version.That offset of the head from the center of gravity (on the Benbo in what it terms the "conventional" position) does not look particularly conducive to stability nor to vibration reduction.
It's a very effective solution in fact and strictly speaking it's not offset, as it's not a normal tripod, so you place 'centre' where you want it.
As a former pro, I can say that in my current life the 190XPRO is the best set of legs for the money. Good weight, sturdy, and the reversible center column make life great. I'd recommend my favorite head to go along with it, the Bogen 3265. Shot with Hasselblads on it for years, great head, makes fast setups super easy. All together you'd look to pay about $250 together for the two, but you'd be happy for a very, very long timeI have a Manfrotto/Bogen 190XPRO legs/tilt head combo. It's cheap (for something of this quality) and very sturdy. The load capability is about 8-9 pounds.
You're not understanding my point - I was thinking in terms of physics. For maximum stability the center of gravity should fall on the line that runs vertically from the center of the junction of the three legs. With any offset from that line, whether it's part of the design or not, you'll have some amount of torque due to that offset (which is basically a "moment arm"). Any force on the head is not quite evenly distributed amongst the three legs, which means the stability is a bit less than optimal.
It's quite possible that under most circumstances you don't see a significant difference. However under sub-optimal conditions, such as on a windy day, it might be a bigger deal. Also, tiny influences can add up - it's not like mirror slap has a huge impact either, but people who are after the absolute best shooting conditions buy cameras that have mirror lock-up because they don't want any compromises at all.
You're assuming an equilateral tripod. The legs are all three independent in both length and angle, so the center of force can be adjusted so that each leg has exactly the same amount of weight. That might get more challenging the farther out the camera is (as below), but one could always hang a weight on the other end if stability were compromised. I've shot a lot of outside macro with this setup or some variation of angles and lengths. Never had a problem.
I guarantee you that, in the photo you posted, the three legs have nowhere near the same amount of force on each of them - nor is the center of gravity anywhere near the point where the three legs are connected together.
I've done physics and understands vectors fine thank. Again I sugest you go and try it out. It is not a normal tripod so you can move centre about in a way you cannot with a conventional tripod. You are using conventional thinking it seems!You're not understanding my point - I was thinking in terms of physics.

The gitzo is an attempt to copy the benbo design, but it certainly is not the same. The benbo unilock concept is protected under patent I believe. Though Uni-lock tripods are [were] also made by one of the chaps behind the benbo design. Not that I can find anywhere to buy the unilocks!I can't speak to the Benbo...I'm sure that construction plays a big role in stability and vibration, but I've been using a Gitzo Explorer 2220, which uses the same offset concept, for many years with no stability or vibration problems.
As for the weight limits, I was talking about that with the owner of a local photo store and he said he'd give me a demonstration. He took a fairly inexpensive Silk, set it's legs to full extension, placed it on the ground, and then pretty much threw himself onto it. For a few moments, he was hanging onto the center column, entirely suspended off the ground. The tripod didn't seem to be bothered at all. He weighs probably about 140 lbs.
