If you want a good "gym" lens, invest in a 135 f/2. Not big and heavy, yet incredible in a gym on the 5d III.

More convenient yes, MORE secure, no. I agree with C. Burch, you are adding another potential failure point, period.
So, a single threaded attachment that is frequently unscrewed and rescrewed and subjected to torsional stress during use is going to be more stable than a threaded attachment with threadlocking applied plus a clamping screw that's not subjected to unintentional torsional stress? Sorry, no. Yes, in theory, two connection points vs. one means two possible failure points rather than one. If you were doing a 350' free rappel (I've done one), would you prefer to hang from a single loosely tied knot, or a pair of 8,000-lb-rated carabiners connected in series? The latter has two possible failure points vs. just one - it must be less safe, right?
I can tell you that I spent over a year with the single lug connection, first as a FastenR-2 then FastenR-3 connected to a tripod socket, then with a FastenR-T1 connected through a Manfrotto RC2 plate. I would frequently find the FastenR slightly loose - probably at least once per week. It never loosened sufficiently for the camera to fall - but that's because I quickly got in the habit of checking the tightness of the lug several times a day. In over a year with the FastenR-3 Loctite'd to a Kirk clamp attached to a body or lens plate, I have never had anything come even slightly loose. I know which sounds more failure-prone to me, and I'm not a fan of letting untested theory outweigh empirical fact.
Thanks. So, basically, unless you loc-tite the BR nut to the QR clamp, you still run a risk of it unscrewing?
Not sure - if you slightly moisten the rubber compression washer and screw the lug in tight (with the solid aluminum, no risk of overtightening), probably not. But I see no reason to remove it routinely, so why not use Loctite? The Blue 242 type is semi-permanent - it's not going to come loose with normal use, but with a vice and a pair of pliers you can unscrew the lug.Adding the Kirk1 clamp seems like a reasonable idea, but it just seems to be adding another point of possible failure. I would think the BR screw in post with the rubber ring would stay tighter than a clamp. Has no one ever had the clamp work its way loose?
I disagree. With the Loctite, I wouldn't classify the lug-clamp connection as a failure point, so you're certainly not adding one. Moreover, if you frequently unscrew and reconnect the lug (which you'd do to attach to a tripod, for example), that makes the lug connection a much more likely failure point. There's no rotational stress on the clamp screw, so it won't come unscrewed unless you turn it. Orientation prevents unintentional turning - on a body plate, attach the clamp so the knob is under the lens, on a lens plate, attach it so the knob is away from your body. I've never had the clamps loosen even a smidgen. So, overall, I'd say the BR lug attached to an AS-type clamp (the Kirk or RRS' new flat-bottom clamp) with Loctite, connected to AS-type body/lens plates, is both more convenient and more secure than directly attaching the lug to a tripod socket.
Thanks all for the replies. I figured the magazines that I grabbed at the airport last week (outdoor photographer and shutter something) wouldn't be mentioned highly as they only had about 1-2 articles each that were of interest, it sounds like its more of the same elsewhere.
The failures that I have read about relate to failure of the tripod socket itself on the camera body. I have no idea how the tripod socket is attached inside the camera body? It may vary by manufacturer and some may be more prone to failure than others. I won't risk that. I have a BR strap; however, I only use it on a lens plate, never attached to the camera body.
That must have been a Sony I've never heard that one. I suppose you could take it to the next level and start worrying about your lens mount...
Perhaps we should all just wait 10 more years, and then we'll be able to rummage through garbage cans and get the 5DIII for free.
Let's not bother talking about how much the price has dropped: as technology progresses, the price of older tech goes down. All that I was doing was letting people know who wanted to jump on a good price for today's market. Market conditions will always dictate price, and a year ago $3,500 was the price. If you don't like how things go out of date, I suggest you find a different world to live in.
I agree on this one, depreciated way, way too quickly. To think I bought mine in July for $3,500 and 4-5 months later it could have been had for almost $1,000 less. I don't understand a lot of the posters on here either as money is extremely important to me as well and I sure don't like to see depreciation happen that quick. Had it been over a period of 12-24 months it would not have been so bad, but roughly 30% drop in less than 6 months? I could have used that $1,000 to buy other gear. Oh well, I learned my lesson and will adjust my buying pattern on the next body I buy. Minimum of a year after relaese before I buy the next one.
Yeah of course technology depreciates, but stop acting so condescending like everyone knew the camera would drop 1/3 of it's price in 7 months. Show me one other Canon product that has followed a similar price pattern. There were plenty of polls about when the 5D3 price would drop to $3k and none of them were anywhere close to what ended up happening. And most were about a drop to $3k, if you had said $2500 people would have laughed at you.
I think most assumed it would be somewhat like the 5D2, which was pretty much the same price as it was when it was released even a year after it came out.
I bought the 70-200 f2.8 is II at $2099, then a few days later, it went on sale for $1999. I called customer service on Dec 17, and they said they were going to credit my account back the $100.
I am still waiting for my refund. I emailed them twice asking for a status and they still haven't responded.
Anyone know how long it takes to get a response?
Wonderful idea. Nice photos so far and hopefully, we'll see a lot more!
