Related Questions and Answers

Q: 1. I do a lot of long exposure photography (i.e. 1 to 2 minutes) with a high megapixel full-frame camera. Would this tripod keep a 70-200mm lens absolutely steady in a moderate wind for long exposures, or should I get the 34L version for more stability?

A: Yes, the Really Right Stuff TVC-24L Series 2 Mk2 Carbon Fiber Tripod should be suitable for your usage needs. The flat pate on the top of the tripod has a hook on the bottom that would allow you to hang your tripod or other ballast such as a sandbag or other weight to increase stability if you will be shooting in windy conditions. You would still need to purchase a tripod head that is strong enough to support the weight of your camera/lens for your planned usage needs.

Q: 2. Do the legs open out to particular fixed positions and if so how many? ... e.g., three, four?

Q: 3. I put two Kenko DG Extension Tubes(10 and 16mm tubes) on my Sony a7R IV and Sigma 105mm f/2.8 DG DN Macro Art, but the camera didn't recognize them because of the voltage drop. Will the Vello EXT-SFED2 Auto Focus Extension Tubes have the same problem?

Q: 6. I believe I have these in the original version. Is there any substantial difference(s) with this "version 2"?

Q: 9. is this the apex versa version?

A: The TVC-24L MK2 is a versa apex, the TFC-24L Mk2 Tripod includes most of the features from the TVC-24L Mk2 but swaps out the versa apex for a fixed apex.

Q: 10. I just bought these tubes for my Nikon D7100. I cannot set the Aperture with these tubes. I'll adjust my camera to F/11 and the aperture remains wide open at F/3.5. You can see the aperture not move while you scroll the aperture adjustment wheel. Could it just be I have a defective set???

A: The aperture does not move when you scroll, it opens or closes only when a photo is taken. You may test this by setting the aperture first to f/22, which should give you a fairly dark image. Then, try setting the aperture to f/5.6, which should produce a much lighter image. If you are still having this problem, please email us at askbh@bhphotovideo.com so we can provide better assistance.
