Every time I see something like this, I just shake my head in disbelief. I applaud the designers for trying to come up with something different. There may actually be a benefit to something like it, although all I can see in the future is a court case.
Let’s be real clear on some things. A camera strap is the ONLY way to successfully, safely carry an expensive DSLR. PERIOD. There are a lot of manufacturers out there that think they can reinvent the wheel. Its round, it rolls, it gets you there in one piece. DO NOT in any circumstance believe what they are selling you. If you look at the market and say “all of these camera straps are designed the same,” you are probably right. There is a very good reason. THEY JUST WORK.
I know what you are saying. Why link to them if you don’t support them? Just take this as a public service announcement from someone who really doesn’t want to see you trash your EOS 1D Mark IV just because you thought it looked cool. As another public service announcement I am going to include a list of links to straps I WOULD ACTUALLY BUY. Stay away from gimmicks. You’ll thank me later.
