When you want the best and are willing to pay for it...go for it. I have no problem with that if there is no other alternative. If tripods were only made by Gitzo, I would have a Gitzo tripod (or insert RRS if you like). My Benro seems to be holding up just fine. You'd never know from my pictures that I use a less expensive tripod. I have two 5.5 inch lens plates, one from Jobu Designs ($60) one from China ($16) and honestly I don't see a difference.
And the time spent checking prices is just a couple of minutes on line, type in your info push the send button and the product arrives in a couple of days ( sometimes 2 weeks if it's from China:lol.
I'm sure that owning an L brackett from RRS/Kirk/Markins gives a sense of pride in ownership and the knowledge that it will work each and every time you use it.
For me it is just a hunk of metal to hold the camera and lens, which after all is very light weight. It's not supporting my weight as I do chin ups.
welps, that's paying for brand recognition. Sometimes I do it, sometimes I dont. At the time, the 6D had no other options, and based on my previous dealings and reputation of RRS, it was a no brainer. If other options made reputable L plates for a lower price, I'de go for it, but there's an IF factor. I dont want a heavy bracket. I want a molded bracket. I want AS compatible. *If* I were to buy another bracket, it would have to satisfy those conditions, on top of that, I'de have to see how good the fit is prior to buying. That info isnt always provided, but with RRS, you know you're getting professional equipment.
The sunwayphoto L bracket actually looks like a BETTER product, but I cant verify since it wasnt an option for me. Some people just dont want to deal with product research and that's fine. It would take a bit of research to figure if it's worth the $50 or just skip it and get the branded version.
I bought 2 second hand L brackets that total less than 1 new. The product is certainly good, but not perfect.
