The same old story: So shy of publishing the CRIs

Noticed the power of "press" (and media)?

On article Fotodiox releases new LED studio-in-a-box (49 comments in total)

85 CRI is a bad joke.
Hi, let's make a new studio-in-a-box! What lights? LED - it's the easiest! Well, there are cheap and not so cheap LEDs. What's the difference? It's all about CRI. What CRI? Colour Rendering Index. What?

In reply to:

keepreal: These lenses are very expensive. Does anything suggest there is a decent justification for this? I would not be interested even if they were giving them away. If three elements lenses can be that good, why are other top quality brands like Leica and Hasselblad not also producing them?

My suspicion is this is a case of the "King's new clothes", the marketing aiming at people who have too much money to know what to do with it, as I also suggested about the new exotic metal Trioplans.

What on earth is the point of forking out for this lens or those others? You cannot show it off like a Lamborghini.

Coatings are designed to phase-shift light waves by a length of one-quarter at each boundary so they will eliminate themselves when reflected twice. Multiple lenses do a different job; they are designed to correct for optical imaging errors.

To me, f2.6 seems not enough for a portrait lens in these days.

The process of coating lenses properly is very expensive; it does play a major part in the total of costs of manufacturing. Even more in this case as "a unique coating has been used to reduce flare" and improve transmission.

On the other hand: What possibly can they do? Use 6 or 8 or 10 rather than 4 different layers? Some sophisticated, exotic ones? Improve the body's inner reflections behaviour? What else?

Jim Salvas: Publicity stunt. He could easily have developed a random sample of rolls to see if this is worthwhile. The few images he has shown look like rank amateur snaps. On the other hand I recently saw a gallery show of similar quality.

Develop rolls randomly and decide then. That's exactly what I thought.

Johannes Zander: I used the camera configurator but I am disapointed! There is no way to choose the size of the red dot!

There are so many options available, each camera sold will have no equal.

May I just throw in the idea that mahagony "Swietenia macrophylla" could go for another fashionable material for Meyer-Optik Goerlitzes because it is very durable, hard, very machinable and comes from sustainable sources. Oh, it could be polished to a fine degree of shine as well - Hasselblad I am sure would be able to confirm that.

cgarrard: Good job Richard, seriously. Now I've had stinging nettles once in my life and I'll never forget the experience. To think of drinking it down...wow! I know I know, they don't sting you on the inside, but just a thought.

Anywho, enjoyed the piece quite a bit. I like the simple and subdued nature of the video and think it looks good to me (but im not pro at video either), sometimes less is more!

-Carl

I know of stinging nettles tea and it is very refreshing and actually very healthy. My wife makes it. Says someone from Germany.

Works with Adobe Photoshop v7 as well, probably v6.

The Squire: I'm putting on my nerdy pedantic glasses now...

How can a spring "save a bit of battery life"? It doesn't give you free energy. The motor working one-way will need more power to compress the spring, then if it wasn't there at all. That energy is then released when the lens needs to move the other way.

Someone with more than my Physics GCSE qualification can tell us whether storing energy like this is much less efficient than simply driving the lens the other way with a motor...

SCIENCE!

As the spring load is permanent is it safe to assume that the motor will need a permanent electric current to compensate for the spring load? Unless the motor without an electric current will be blocked mechanically. But then again a considerable break-off force would be needed to free the lens.

Given the new lenses would exist, will special projector lenses follow or will these lenses in reverse be able to serve as projector lenses as well?

Because it wouldn't matter? DPR write their features/articles because they reflect what they think.

Quoting from the article itself: "The downside to the design is barrel distortion".
Hey, what about the other remaining optical aberrations? There is no such thing as a silver bullet.

bernardf12: Olympus dials are so nice to use, you turn them even when the camera is off - sad but true.

Glad to hear I'm not the only one disliking the fully articulated screens. It's a deal breaker for me.

Weather sealing is expected on all cameras nowadays, as is dual AF (PDAF/CDAF).

We are making progress, new cameras have only about 2-3 serious omissions nowadays, unless it's a Sony :-)

"Weather sealing is expected on all cameras nowadays..."
Actually, it is safe to say that all cameras nowadays, resp. their sensors, are well protected against stray light; well, more or less.
