I called Really Right Stuff today (see July 1 commentary below). I was told that the L brackets are back-ordered, but that all backorders should be shipped by the end of the week.
I can’t say I’m particularly pleased to learn that my order is backordered after being promised immediate shipment on June 6. That’s with no updates whatsoever via any means, no response whatsoever to my email queries about order status, a web site that gives no indication that my order was backordered, etc. Really, I think it’s not Right to do Stuff to customers like that.
When I finally do receive the L-bracket, I’ll report on it here. I’ve used the Really Right Stuff L-brackets for the Nikon D70, D2x, D200, Canon 5D and Canon 1Ds Mark II, so I have ample past experience by which to judge the latest 1DM3 offering.
I’ve also ordered the Kirk L-bracket for the 1DM3 (thanks to R.P. for the link to the Kirk website). Of course, I’ll compare the two and report my findings here; look for my report in the next week or so. After all, investing in a US$4500 camera is stupid if one is loathe to spend a few hundred dollars more on a vital piece of equipment to make the camera maximally usable on a tripod.
