I know there are a few different tripod and head threads open now and I apologize for keeping the topic going, (perhaps longer than it should), but as I am now for the first time getting into the BGC with a 200-400 + TC, (I think that qualifies), I am going to upgrade my support system as well and I am trying not to make some of the mistakes I have made in the past by not doing enough research. Since it is somewhat impractical to field test this equipment, I rely on the very experienced and talented folks here at the Cafe to help me. So having said all that, here is my question; Since the 200-400mm Vibration Reduction lens suggests that you leave the VR on while it is mounted to a tripod, wouldn't this compensate for any slight vibration that might be attributed to a less than rock solid tripod/head setup? For example, I have a RRS BH-40 (medium head rated to carry 18 lbs) and a Arca B1 rated to carry 90 lbs. I would much rather pack the RRS BH in my kit as it is less than half the weight and size, but will no doubt also result in a measure of vibration with the 200-400/TC/D2x attached that would not likely be present in the Arca B1. However, I have used the 70-200 and the 18-200 VR lenses and found the VR to be quite accomplished at reducing the vibration in hand held use. Since I am getting a bit bored, sitting at the window now, waiting for the brown truck to deliver my 200-400 lens, (Thank you Nancy) my quizzical mind is rambling. I though a discussion of this topic might be interesting at the very least for me and hopefully others. I guess when I get my lens, I will be able to test this theory and will happily share if anyone else might be interested.
