LuMu light meter - just bought it

Sekonic Twinmate (L-208). No need to fuss with capacitative screens, phones with low batteries and a total package (phone + sensor) bigger than your hand. MUCH faster in use.

Cons: not so good in low light...but if you don't have those exposures memorized, that's where the iphone can serve as a backup.
 
Hello there,


As a recent convert to Analog photography, I found myself baffled by the fact I need to meter light etc. I have a Konica III and a Minoltacord TLR, both that come without a built-in light meter. I have started using a free iPhone app which meters relatively well but only does reflective light metering obviously. I went to a local used camera store and picked up a great little Sekonic L_28C meter that works wonders and was cheap too. Having this meter, I have started appreciating the art of Incident light metering. My results are way better since I have it, as I normally shoot people up close.


However, with summer just around the corner (wishful thinking...) I don't really want to carry the meter with me as it'd be additional bulk and when I don't carry a bag, it just won't fit anywhere.


See where I am going with this?

It's expensive and easy to lose but I could not say no to it. I ordered it on the spot, $129USD and comes with a neck strap and an additional leather case that I can attach to my camera's strap. I am in love with the concept and am waiting to receive it (which will be soon I hope).


My question is very simple. Are any of you using it already? What do you think about it, how does it stack up to a "real" light meter? From their video, it seems to be doing rather well...


Thanks,

Ben

Don't know enough about electronics to agree or disagree with any of the posters here on how good either the one you have bought, or the other mentioned might be. But you have a really good meter in the Sekonic L-28C. I have the L-28c2 which I find to be surprisingly small. The big light domes on the Sekonics seem to give superior results to even a Gossen Luna Pro SBC. They even work in surprisingly low light all things considered.

But the bottom line is what tickles your fancy. When you get the meter you ordered, and if your really like it, you have done the right thing.

Someone mentioned a Luna Pro above. I have one of those as well. They may have the same amount of cubic inches as the Sekonic, but I think you might find the Luna Pro a little easier to carry due to its flatter profile. They do need an adapter or a wein battery since they were designed for mercury batteries. But if you get a properly working model, you will no doubt find you like it.

But again, I think you already have as good as you need in the Sekonic.
 
Oftheherd, I also have the L-28C2, forgot to add the 2 to the end. It's a great little meter indeed and very simple to use. A bit of a pain in the back when you need to slide the "high" sheet underneath the dome in brighter conditions as mine sticks and is hard to get out. But otherwise it's great indeed. Having bought it my pictures have come out much better. I was a "light meter denier" but having finally bought one, I now understand the importance of the Incident light. For my photography, it seems to suit better.

Countdown begins to the LuMu, I am very surprised that none here actually has it. There were over 2000 backers... It's my second Kickstarter purchase after the Pebble which really came through (updates / etc) so I am hoping these guys will deliver as well!

Ben,

I was a backer of the project and really like my Lumu. -4 EV incident with a touch screen interface is hard to get by otherwise. Unless you pay several hundred dollars it's almost impossible to get another equivalent meter. And if you buy something 20 years or older you'll have to have it recalibrated anyways, given that kind of sensitivity,

Go shoot some night landscapes and don't worry about the nay-Sayers :)

The issue with the microphone port is that it has "some" power - other than professional microphone "phantom" power, which is defined to be 48V, the "plug-in-power" of 3.5" jacks is very vaguely defined, the devices on my table right now range from 2.8 to 6.4V, with the value on my smartphone variable with the background illumination. This is not really a good base to build a affordable and small quality analogue measurement device on.

Voltage can be regulated. And analog Ports can be used to transmit modulated or digital signals.
 
I have several light meter apps on the iPhone ... FotoMeter Pro, Luxi, Light Meter, and a couple more. FotoMeter Pro and Luxi (which works with the Luxi incident dome) are my favorites at present.

The LuMu device looks good as it is likely both more sensitive and more accurate.

The advantage of having a good light meter that works with the iPhone is that I always have the iPhone with me anyway, and the LuMu's dedicated hardware is likely to be both more sensitive and more accurate than just using the built-in camera's sensor as a light meter. The LuMu is certainly a smaller, more convenient device to carry along than the L-358 brick.

Good to hear a positive report since mine just shipped. :p

The -4 EV bottom end is important to me because I do a lot of low-light shooting. After years of being used to the -2 lower end on my M6TTL & M7 & -1 on my Luna Pro, I have been frustrated by my digital cameras & Digisix bottoming out at 0, especially since the sensors on the digicams are so much more usable in low light.

Wow you guys really know how to break a man's mood...

Anyways, just got an email from them saying it's on its way and might even get to me in Tokyo by Friday. If so, I'll have a review back to you about early next week.

And taking all what was said above into account, if the accuracy is decent and it isn't as prone to failure as some of you said from the fact that it's feeding the phone through the audio jack, I'll be happy with it. My rangefinder camera is smallish and I am comfortable with it hanging around my neck all day. If this means I won't have to lug another piece of equipment, the 129USD is worth it for me.
The Sekonic meter which I have cost me 30USD at the local store and it's doing a perfect job but it's still an extra piece. Having a bag on me like I do on workdays, I don't mind having it. On a saturday going from pub to pub with the guys and shooting around, I'll be happy with the LuMu hanging on a neck strap as thin as a fishing wire.

It all boils down to it's performance I think, so let's see. I've preloaded the App and it seems to have some settings for calibration (which creeps me out having read some of your above comments). Time will tell.

I'll post back.
Ben

Cheer up. You'll have fun. People look at me askance with a lightmeter. With yours 80% an iPhone people will recognize most of it and be filled with envy they don't have what you've got or know what it is doing. As I said, I do like the very plain large type interface.
 
$129 ?
Wow...

Looks like it'll be easy to accidentally snap it off at the jack, destroying both the device and the phone.

I'll keep using my Digisix, thanks.
 
Was nice to see some positive responses. The LuMu team must be overwhelmed, yesterday I got 3 emails automated. One said my item has just shipped and should get here in 3-4 days and that I can check the status on the tracking website, but no tracking number was attached. Then another just said that my item was shipped, and the last and final email actually contained my tracking number but said that shipping would take 10-15 days :)

I am hoping the first email is what is accurate... I just checked and it left Ljubljana so I remain hopeful I could do some tests over the weekend.

Again, the $129, if it does solve a problem I am having, is worth it for me. I am also worried about the fact that i might lose it or break it when it's attached, but I'll just try my best not to do so. If it means I won't have to always carry an extra meter, i'll be happy. I use an old KonicaIII camera that cost me 70USD and works brilliant. I could have also bought a Leica for $2000 so I am still in the positives... This is of course not to compare the quality of the two, but I am very happy with the shots I produce with this piece of Japanese history.

I got one in December and tested it along side my Sekonic. It was within 1/10 of stop from the Sekonic, adjusted the compensation and they both read exactly the same now. Accurate and no problems so far. It's certainly convenient and compact for travel when all you need is an incident meter. Just my two cents.

That's good to know, thanks! I'll do that first and couple the little guy to my light meter. It should be reliable from then on I hope.

Very nice to hear that the people who actually have the thing like it. I think it's more important to me at this stage than the comments from people who don't have it. I guess it does not suit everyone which is just natural, but the people who do feel they'd like it actually end up liking it. This could be me :)

The only reason I have this meter is it`s low-light capability, otherwise my Twin-Mate L208 or VCII meter are much quicker and easier to use.

I see, I am more interested in using it for all my shots but indeed the fact you needing to insert it / start an app etc, will take longer than just metering. Having said that, I don't much shoot at an environment where I'd need to meter on an instant, I usually settle down etc.

Saw your photos, very nice! We walk the same streets, nice to see another analog photographer in the Tokyo area with similar interests...

Cheers,

Thanks for the kind words! :)
 
After considering for a bit yesterday, I placed an order for one. It fills the need of having an incident meter with me when I might not have thought I needed one, sort of the same goal as the Lumi, but it's got more range and likely better accuracy. It's small enough and cheap enough that I can stick it in the pocket of my shooting bag and not worry about it, just use it when appropriate.

Looks like it'll be easy to accidentally snap it off at the jack, destroying both the device and the phone.

Huh? Have you ever broken off a headphone jack before? You don't leave the meter in the phone jack all the time ... and you handle it with the respect you would any other meter. Do you normally whack your incident meter against things and break off the incident dome? I've been using rotating head incident meters for forty years and I've never done that.

I just don't get comments like this.

Nice!

I just checked the tracking and my LuMu is in Yokohama already so I guess I'll get it by Friday :). I'll post back. Shipping sure was fast, I ordered it on the 23rd, today was the 26th, 9000kms from Ljubljana.

My plan is to continue using my trusty Digisix 2 in decent light & have the Lumu ready for available darkness.

I find the price to be about 10 times too high for what it is, given that you need an Iphone to use it on anyway,
BTW, what would be the best light meter app recommended for iphone guys?

"Light Meter".
Free app.
The huge benefit of this app is in the "live view".
It also have movable meter area.
