Kirk Security Strap review
« on: January 30, 2013, 07:14:48 PM »
Review of  http://www.kirkphoto.com/Kirk_Security_Strap.html

Background, I haven't used the popular BlackRapid strap or other variants. My issue with the BlackRapid is that you have to screw something to the bottom which precludes easy Swiss-Arca plate usage. I know many got around that by using a SA clamp, but the setup seems kludgy to me. Additionally the BlackRapid solution seems over engineered to me. As an engineer I would opt for a simpler design, the swivel buckle, screw in attachment and such looks like too much, never mind adding a Swiss-Arca clamp, which also makes it much more expensive by the way.

Enter the Kirk Security Strap which had the features I wanted on paper.



A built in clamp. A strap which attaches directly to the clamp. Minimal failure points and foo. How does it stack up?

The claim to fame of the BlackRapid is rapid shooting. Important to professional event shooters, less to me, but as it turns out I suspect that is more marketing than reality. As it is the Kirk has zero issues with rapid deployment. Instead of sliding the camera along the strap, a move that seems error prone, with the Kirk you can simply raise the camera to eye level without readjusting anything. It just folds more or less in half with the padded part staying in place. When done drop it back down, zero fuss. Frankly it seems like LESS fuss than the BlackRapid, but as I say I haven't used that one.

Second, how does it 'sit' when by your side? It comes from the factory with the clamp knob toward you. This is a neat feature, what it means is that because the clamp naturally lines the camera up in a particular orientation (front-back) the knob is always there giving some standoff distance between the camera and you. Keeps the back of the camera from knocking into you. Cool.

Third it has a rail on the bottom for quick mounting on a SA system.

Fourth I'm not a walking advertisement. No logos blasted over it, the unit is extremely lightweight and low profile.

That's the good. The less good is that the strap isn't a super deluxe item. Fine by me, actually perfect for me, I don't want some overdone solution. Just a simple strap thank you. If you don't like it, it can be easily replaced at any rate.

Also with the default strap it wants to go over one shoulder (at least for me), not across your chest to the other shoulder. Again my preferred approach, I like being able to quickly take it on or off. If you prefer across the chest then replacing the strap with a longer version will do it for you.

That's my take.

Oh boy! I have a BR, and it's been great, especially for a large event where I'm out and about but not using a tripod like Burning Man. For when I'm out and about, but want to switch to my tripod, this would be perfect. Thanks!

Your very welcome. Here's the picture of the underside to readers know what you mean (I should have posted this)



The feature I like the best is again how the knob also acts as a kind of a standoff from my hip. I spent the weekend at an event with a full time photog who had a BR strap. I'm not trying to cut on BR, but he had to keep a hand on his camera at his hip as he moved (quickly) around. With the Kirk that seems to be less of an issue. FWIW.

My BR strap screws into my Kirk plate (Arca), issues? None.

Thanks for the good review.

For me, at $75 it would have to make my coffee in the morning and open doors for me all day long!

Dollars in my pocket shield me from much inconvenience.

As Ben Franklin said: There are only three things you can count on in life:

1. An old wife.

2. An old dog.

3. Ready money.

My BR strap screws into my Kirk plate (Arca), issues? None.

The bit about this is that you can leave your Arca plate on your camera, and very quickly and easily remove the camera from the strap, and put it right on the tripod in just a few seconds. With the BR you need to disconnect it from the connector, unscrew the thingie, clip it back in so you don't lose it, and put the camera on the tripod.

This strap, to me, seems quicker and easier than the BR screw-on connector thingie. Not that I'm against it, I have the BR-7 I think it is, and works awesome, but there are times when I know I'm probably going to be switching between strap and tripod.

I think what crasher said or meant to say is that you can screw the BR into a Kirk clamp (or any other QR clamp of your choice), and have the same as with the Kirk strap, only with additional pieces of metal between the strap and the QR clamp. No need to disconnect the connector.

It seems that that design is set up for the clamp on the camera. If I wanted to clamp it onto my 500mm lens, wouldn't I have a twist in the strap?

Ahh...ok, that makes more sense now.

"A built in clamp....... Minimal failure points.... How does it stack up?"

Pay attention Neuro, an engineer is talking about "minimal failure points."  That means this is BETTER than your combination of pieces loctited together creating multiple failure points that you believe is even stronger.

"A built in clamp....... Minimal failure points and foo. How does it stack up?"

Pay attention Neuro, an engineer is talking about "minimal failure points."  That means this is BETTER than your combination of pieces loctited together creating multiple failure points that you believe is even stronger.

Yes any engineer will tell you that a simpler system is better than a more complicated one. Better in this sense means less failure points, less R&D, less to manufacture, less to test in production, less to support, and less to manage for end of life. However, that doesn't do you any good if the user needs or wants the more complicated solution.

In reality I think there little real world difference between the two systems. Which one is better is a matter of taste, and so far I think BR has probably sold more than Kirk. Marketing place a big part of perception too, in this case I think BR has given the impression that only their system gives you the ability for rapid shots.

As I said the simplicity of this system works for me, and in real use is comfortable and lets me get off shots easily and quickly.

I like this but, unfortunately, I have an aftermarket vertical grip on my 5D2 and really wouldn't trust the bush on it.
Some cameras… With Canon written on them. Oh, and some lenses… Also with Canon written on them. Oh, and a shiny camera with Fuji written on it too...

"A built in clamp....... Minimal failure points and foo. How does it stack up?"

Pay attention Neuro, an engineer is talking about "minimal failure points."  That means this is BETTER than your combination of pieces loctited together creating multiple failure points that you believe is even stronger.

The Kirk Security Strap wasn't part of that discussion.  My original point was that the BR lug Loctite'd to an AS-type clamp was more secure than the BR lug directly screwed onto a camera/lens attachment point, and I stand by that point.  Yes, it's one more connection, technically, but the Loctite doesn't count as a practical possible point of failure.  In that comparison, the parts of the BR hardware - carabiner, pin, etc. - are identical between the two setups, and the sole difference is the directly screwed in lug vs. the clamp in between.  Since unscrewing of the lug which is subjected to torsional stress during use is a much more likely occurrence than unscrewing of a Loctite connection or a clamp screw not subjected to torsional stress, the latter is more secure (despite having one more 'countable' potential failure point).  My own empirical evidence backs that up.

By the way, a good engineer would understand that it's not only the number of possible failure points that matters, but each points' probability of failure.  If an engineer working on a project of mine (I do hire them, on occasion) told me that three connection points each with a 0.0000001 failure rate is 'less secure' than one connection point with a 0.001 failure rate because fewer possible failure points automatically means more secure, I'd certainly 'pay attention' - and I'd immediately fire that engineer.

The Kirk Security Strap clearly is an even more secure setup.  There's no carabiner, no pin, etc., so of course it's more secure.  I'm a bit concerned about the idea of using the screw as a 'stand off' from the body, as that would seem to carry the risk if the screw know being loosened as it rubs. Not sure if that's a real issue, in practice - but it's something I'd watch for (and just switching the orientation would solve the problem).

The other issue is convenience - not sure if there are tradeoffs there with the Kirk strap.  The issue of a lens plate was mentioned - the BR swivel allows 90-deg rotation for body vs. lens plate, not sure it the twist of the Kirk strap would be an issue (likely not).  Also, my BR strap works in conjunction with a backpack (a full pack - shoulder straps with sternum strap, and a hip belt), because the strap does not need to move/slide to raise the camera.

FunPhotons - thanks (again!) for the great review. I'd love to hear your thoughts on lens plate use and backpack compatibility.

Neuro, yeah, most engineering is just over engineering and calling it a day.

Before purchase I had thought the lens plate feature was kind of silly but it works fine and I like having it there. I had thought it added to the profile too much but it doesn't add anything noticeable and is a nice feature frankly. Likewise with a backpack it appears to be working great.

I'm not seeing any issues with the knob getting loose.

Anyhow they are both great solutions and I'm really liking this one at least.
