Gives readings in Cd/m2

but you can always convert to EV in your head, its just a different set of numbers.

And I can assure you that if you need to ask how much they cost then you won't be buying one.

Oh, and virually flare free (< 1%) for those that worry about those sort of things when they really needn't.

Principal Applications

Measurement of the luminance of CRTs, LED’s, and EL’s.
Measurement of road and tunnel brightness
Measurement of rail-system signals
Measurement of road and airport signals
Measurement of illumination and outdoor signs
Measurement of illumination equipment and devices
Research and measurement testing
Measurement of device brightness

Yeah, cool isn't it. Measures colour and colour difference too.

Nothing stopping you from measuring anything you like if you want to.

The "Principal Applications" listed allow them to charge much higher prices for it. It ain't designed for photographers but that doesn't mean you can't use it for photography. When was the last time you saw a 1deg sopt meter for colour.

Finally. This is what I need to finally take my photography to the next level. At least until that next lens comes along....

Very cool tool though!

I think I'll keep my powder dry because I doubt if I bought onet it would make me any better a photographer than the meters I already use.

BrianShaw · Mar 15, 2016

It is an engineering and scientific caliber tool; not a photographic tool. I've used a similar piece of equipment and doing the conversion to EV and exposure settings. It did not improve my photography one iota. In fact, it made it worse since I was spending too much time fiddling with measurement and maths instead of the image.

Now I worked out how to convert the result to Ev on my calculator its a breeze. I rekon there must be an "App" to do it if someone can find it or otherwise write one to convert Cd/m2 to an Ev.

Having said that, all you need is chart which shows Cd/m2 range for each Ev so it would be very quick to look it up.

Minolta has been making these meters for many years. I don't think the luminance meter can measure color.

RobC · Mar 15, 2016

you obviously didn't read what's at the link I posted then

Chan Tran · Mar 15, 2016

Where does it say that it can measure color?

RobC · Mar 15, 2016

Sorry, I posted the wrong link. I changed it to correct one which is

It doesn't. Obviously the OP is the one who didn't read the link.

[Update: I see that he has now corrected the link, to point to a colorimeter]

RobC · Mar 15, 2016

yes I have the Spotmeter F with its manual too.

Mr Bill · Mar 15, 2016

We had a couple of somewhat similar meters, earlier versions of the "incident style" Minolta colorimeters, in the large photo lab where I put in a lot of time. We mainly used one of them for periodic screening of our color-correction booths, as well as other print viewing areas, including "dust spotting" stations. They were good QC instruments for this sort of thing, able to spot early signs of lamp deterioration or to confirm the situation where someone had mistakenly installed the wrong lamps. If such problems aren't caught quickly, a lot of work may have to be reprinted.

The second meter was a spare, able to act as a referee for the first, or as a backup when the other was out for recertification, etc. The cost of the meters was insignificant in the whole scheme - our daily print output was more than most busy pro photographers would have done in their entire career.

I don't see any real use that an ordinary photographer would have for such an instrument, but plenty of other specialists might.

Yeah, the one that says "Luminance & Colour Meter" which takes 1 degree spot readings

Chan Tran · Mar 15, 2016

If you calculator can have log base 2 (like in excel) then the formula is

EV= log2(L/(K/100))

If only log10 or ln is available then

EV= log(L/(K/100))/log(2)

Where EV is EV for ISO 100, L is luminance measured in cd/m^2, and K is the K factor of the reflective meter which is usually 14 or 12.5

ic-racer · Mar 15, 2016

The 160 is 1/3 degree; nice as I don't know of a photography meter with an acceptance angle that small. Perhaps you have found the modern version of the SEI. However, with an internet search I don't see where one could buy it or it's price.

Well over £2000. I'd get a couple so you have a backup.

and I would be inclined to check its size and weight in the spec page before buying one.

Chan Tran · Mar 15, 2016

Got to save the money to get the Illuminance meter as well.

RobC · Mar 16, 2016

Either the person holding it is a four year old or this thing is a humongous beast of a lightmeter!

Still, good for impressing people that know size matters.

I don't see anything about measuring color other than a basic color temp correction. It's not a spectrophotometer. And $3000 won't even buy a toy
one of those, at least in any continuous tone capacity. This is just a fancy light meter.

RobC · Apr 4, 2016

I think you came to the party well after everyone else has left.

DREW WILEY · Apr 4, 2016

I was having my own party. I recently picked up a barely used Pentax digital spotmeter for $200. Timely, since my oldest one is one its last legs, having endured an awful lot of torture in the mountains and deserts. But all of them match readings perfectly. Otherwise, when I want a color temp reading, I just grab my Minolta color temp meter. When I want a luminance meter, just grab my basic Sekonic footcandle meter. No need for some "one man band" gadget.
