One of the most-viewed posts on Enthusiast Photographer is about my solution to the dilemma of using the Black Rapid Strap with the Arca-Swiss plate system, in my case my RRS-L-bracket on my Nikon D90.
For those of you who haven’t seen what I’m using, here it is:
On the various forums I frequent, there is invariably a mention of a series of e-mails Bosstail (a Black Rapid competitor) has on their website from Nikon and Canon support regarding the use of the tripod mount for attaching the strap. Predictably enough, they are negative on the idea.
Personally, I think that information from Bosstrap is disingenuous – Given the popularity of these types of straps, you’d think there would be an official word from Nikon/Canon, etc. on this matter, especially if there was risk to the equipment. As best I can tell, there is no official word or warning from Nikon or Canon on their website or in their user manuals referring to the use of straps in the tripod mount.
No – I’m not an engineer, but I don’t think the forces applied to the mount are significant compared to use with a tripod plate/clamp/head setup. It seems to me that a 70-300 lens (with no foot) mounted on a tripod would put significantly more stress on the mount than the lens hanging down on a Black Rapid or similar strap. I don’t think that is the common use case anyway – the biggest lens I’m using when mount to the BR strap to the tripod mount is my 18-200. When I’m running around with my 80-200, I’m using the mount on the foot for the strap, which I’d think would have the same benefit on the strap as it does on the tripod – more balance and less stress.
Unless I see an official warning from the camera OEM’s, I’m not going to worry about it. A copy/paste of e-mails (that might be legit, but sound more like CYA than policy) and 2nd-hand statements from “Nikon staff” aren’t very compelling arguments. Additionally, it seems like Black Rapid and similar guys would be opening themselves up to lawsuits if their design inflicted damage on the camera.
Lastly, on FredMiranda and Photograhy-on-the-Net (POTN) (and others) I’ve seen many, many comments from working pros who have been using these straps with big lenses and flashes for multiple years and reported no issues with damage to the camera base.
Net: I think Bosstrap is being a little shady and using FUD (Fear, Uncertainty and Doubt) to drive sales. Show documented, engineering-based proof or publicly official statements from the camera manufacturers, not anonymous e-mails from some pimply-faced Nikon support tech trying to keep his job and nebulous “Nikon staff”. If you can’t do that, innovate, engineer, market and compete fairly. FUD is a sign of the weak who can’t compete with a better solution.
I’d really like to see something official from Nikon/Canon on their site and in their user guides. I think my use of the Arca-clamp on the L-bracket further mitigates any concerns by spreading the weight and stress beyond just the screw-point of the tripod mount, but I doubt it makes any real-world difference. I strongly doubt there is an issue for anyone using the Black Rapid FastnR in their tripod mount (the standard way if your tripod mount doesn’t live on your camera).
I do wish Nikon and Canon would declare one way or the other. In the meantime, I love my Black Rapid RS-7!
(I did a quick check on Black-Rapid’s site – no mention of the Arca-Swiss-compatible solution they alluded to at CES…)
