Mistajolly: Now, that's what I call a MFT lens. Let's hope the quality is good enough.

On Wednesday 22nd September at their Photokina booth, I tested a prototype of the lens with the blades fully open at F/2 and using my Olympus Pen E-PL7. I was extremely pleased with both the handling and the quality: Extremely sharp, crispy and practically no noticeable distortion down to a distance of 20 cm, some visible barrel distortion finally at the nearest distance of 4 cm ; but hej, 4 cm! Considering the test conditions in a large hall with details everywhere in the corners rather than a blank white sheet to test vignetting, only a very small amount of vignetting could be found (at F/2), no idea about CAs (rather unlikely with a super wide angle lens).

I tested the mft 7.5 mm f/2 lens today at Photokina. I should say that I was deeply impressed by the small size, the low weight and the very good optical performance. Would I know how to upload pictures I surely would like to show a few examples of photos I took.

CameraLabTester: Very impressive the first couple of minutes and gets boring after a while... Don't get me wrong, it is a great work! But my attention span may have been put off by that Enya like music. Not for everyone's cup of cappuccino, but impressive nonetheless.
Well done visuals, garage band music.

I do agree. Saw 10 secs? You've seen them all. It's overdone.

Androole: Pretty expensive for what it is at $250. I guess it needs to have gearing inside (possibly a cogged belt) to match the angular rotation of the two arms to give the linear movement. But honestly, it seems very pricey.

I guess you need to take your profit early when it comes to simple mechanical design like this, before it gets knocked off and sold for a fraction of the price.

@ cdembrey: Thanks!

It will either house a pair of belt/chain drives or a pair of parallelograms (i.e. two pairs of two arms each linked as parallelograms).
What is the maximum load allowable? Does anyone know?

On article Throwback Thursday: when studio lenses retire (203 comments in total)
In reply to:

evogt500: "Do you have an older, out-of-date lens that you still hold on to? What keeps you coming back to it? Let us know in the comments!"

I keep all my lenses, as I think they are never "out of date". They are MF only, and do not control flare as well, but they make some spectacular images that modern lenses can't match.

That being said, thanks DPR for the great article and keep up the Thursday Throwbacks.

I mostly agree. That being said, people say that resolution (lines/line pairs per mm) can not compete with today's sensors' requirements.
Does anyone know what resolution such a treasured out-of-date piece of optics commands of, typically?

Yeah I remember having paid the sum of $400 for a 15k PCMCIA card.

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?

On article Meyer-Optik Goerlitz launches 3-element 95mm F2.6 (124 comments in total)
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.
