Is that true?! Wow....I definitely didn't know that/hadn't heard of that. I even owned the 5' photoflex octa and didn't know that.

I stand corrected.

My Photoflex boxes and umbrellas measure as marked across their face. My Calumet 45" umbrellas and Photogenic Eclipse umbrellas also measure as marked, I believe. I'll double-check to be sure.

Dave, how would you compare the time and "fussiness" it takes setting up an octa (large size) to the PLM?

I originally wanted to get one of each of the PLM because I thought they were cheap and easy to set up. Now I'm not so sure if I want to get one of each or maybe just one that I would think I really needed.

Dave maybe when you are done playing you can look into modifying the joint of the cage to shaft connect with a simple quick disconnect air coupler. For a few bucks I think this would greatly improve the setup and take down to something you can at least live with.

Great idea regarding the quick connect air coupler. They fasten very tight (to minimize air leakage) and release very quickly. Here's a set with (1) female coupler and (4) male inserts for $ 3.99 plus shipping (external link).

My 7ft Photoflex Octadome 3 is 7 ft from rod tip to rod tip across the face.

I just checked, and all of my boxes measure true across the face, my octa is true point-to-point.
Most of my umbrellas measure across the curved arc, not across the face. I just measured my 60" Wescott, and it is true across the face.

Wow, thanks for the share! I ordered mine in May with the diffuser, so I cannot wait to get my hands on it. This gives me hope.

All of my PhotoFlex Softboxes measures accurately across the face.....
My 24" Photogenic Beauty Dish measures accurately across the face.....
My 60" Calumet Umbrellas measures accurately across the face.....

Hmmm, never heard of included the arc in one's measurement, not saying that it's not done or that it's not true, just never heard of it or seen it, interesting.....

Last image of the night:

A bare-bulb Sunpak 120J is able to fully illuminate the 51" PLM V2 with no spill around the front edge of the umbrella. However, as you can see, a fair amount of light does travel through the material. The black back covers are not yet available. I have one on order and will retest when it shows up.

Did you also get the diffuser? I would be interested in how even the light is with it on. I know it is suppose to have a hot spot in the middle, but I am curious.

Yes, I ordered the front diffuser but that, like the back cover, remains on backorder.

A Rotalux or umbrella-style octa would be easier to assemble not counting the time required to install the inner and outer baffles. A conventional 8-rod-plus-speed-ring style octa would definitely be fussier. The PLM V2 is "fussy" only in comparison to standard umbrellas.

I think the PLM V2 will be quicker and less frustrating to assemble once I etch index lines on the adapter rod. Trying to get the locking screw to seat in the adapter rod's hole by feel is a needless annoyance that can really slow things down.

Hi Dave,

Nice photos and all but I'm still waiting for someone to show me the 'magic' of the PLM.

Other than having 16 sides and creating a more round catch light I just don''t see the attraction at all.

It's an umbrella. Not one person has been able to show mw images or identify properties that make it great.

Perhaps you can do some shooting with the PLM Dave. It looks nice in your house but I want to see the light that falls on a subject.

I just don't get it. Again, it's an umbrella being marketed as something brilliant, and I'm not seeing it.

I was under the impression it is more efficient/even than a normal umbrella. And that is mostly my draw toward it, on top of the diffusion cloth over the silver PLM. But yeah, I'd like to see samples before buying into it vs. just grabbing larger umbrellas

Another one of Paul C. Buff "money makers" that's cleverly marketed toward his fanboys.....

Looks like Paul is angry at Dave's review or my comment regarding the screw driver thing. LOL. Wait until he reads Mark's and Rob's comments. ROFL!

Paul C Buff wrote:
It is assumed that the vast majority of users will use the PLM on the same type of light regularly. If a user wants to swap from 7mm to speedring mount regularly we can supply a spare rod and you can leave the speedring attached and the use the other rod for mounting the 7mm rod.

If you only want to use the "standard off-center umbrella" mode (7mm rod) there is a set screw on the back that can be tightened to secure the center rod in place. Then you can open and close it like a normal umbrella. Then again, if you want a "normal umbrella, go buy one. If you don't appreciate the PlM go get an 8 rib umbrella with shaft ticking you in the eye and complain about its shortcomings.

Personally I'm amazed at comments from "professional" photographers who think the world is falling because they must install one screw one time and, OMG, I don't have a screwdriver. Are photographers really that challenged?

As for the sleeve, we are getting sleeves made.

My God people, I never said PLM was an ordinary umbrella . . . that's why it's called a Parabolic Light Modifier (PLMâ„¢)

I really think the few naysayers here ought to go in business and see what they come up with beyond negative rhetoric and armchair criticism. But I guess that's what drives some forum posters.

Paul C Buff wrote:
If you are using it with the same type light . . . IE, Buff or Elinchrom with speedring, or other lights without speedring, setting it up take about 20 seconds and doesn't require a screwdriver or any other tool. We could put the screw in for you if you want to pay a whole lot more in shipping, but then you would have to take it back out to use the 7mm mounting method. Or we could raise the price and send a pre assembled set of shafts for every possible use.

Let me ask . . . how easy is a Bron Para or standard softbox to setup?

It's not that I mind comments but I do mind comments that tell me I should change the design after spending tens or hundreds of thousands of dollars inventing/developing/a​nd having parts made because a customer would prefer I had designed it a different (and more expensive) way.

If you would like to spend a couple hundred dollars on a PLM I could probably design it so everyone would be happy . . . but of course I wouldn't sell 1/20 as many and everyone would **** about the price and say "why does this thing cost so much?

I guess I should learn and just produce my products and stay off the forums and in my ivory tower like other manufacturers. It really doesn't matter if I'm on here or not . . . it's **** **** **** either way.

Got an idea . . . those of you who don't like me . . . buy from someone else. Those that do, I'm here to help in any way I can. Those who think they can do a better job designing and manufacturing and marketing . . . go for it.

So go ahead now, you few that are unpleased with everything I do or say - fire away as usual. I'm up for a good barroom brawl if that's what this forum is for.

A barroom brawl! LOL. At his age, he shouldn't be thinking of finding ways to die sooner. But he definitely reminds me of kids on YouTube commenting on videos and "the tough guy behind on the keyboard behind the monitor".

Anyway, back to discussing PLMs.

So, to be clear... PCB is selling this with the expectation of it not being collapsed much? He says it takes 20 seconds to set up if you don't switch types of lights (lets say ABs/Elinchroms). But tetrode, you mention with the cage adapter, you can't collapse the PLM, and thus implying it would be difficult/insane to transport it as such?

Dave, looking past the marketing fluff about the shape and the pointless looking cage adapters, will it function as an ordinary umbrella - can it open-close instantly when used as a normal umbrella and does it look like it will stand up to regular use?

If so, it still ticks a lot of boxes for me. Disposable price, full-length sized, compact, 16 sides, 7mm shaft.
