I once had a Leica universal bag similar in size, quality and prize to this Ona Berlin II bag, but not of messenger type. The original bag had rigid dividers. So, I think everyone will appreciate these customizable soft paddings.

The bag may even look attractive to non-Leica owners, e.g. within the mft community where I found there is lack of profoundly good quality bags.

One detail however, strap holes ought to be oval not circular round.

On Hands-on with new Olympus PRO 8mm and 7-14mm lenses article (269 comments in total)
In reply to:

StefanD: About " the new 7-14mm wideangle zoom (on the left in this picture) is considerable smaller and lighter than full-frame equivalents":

Compared to the Canon 16-35 F4, it isn't that much lighter or smaller:
Weight: 534 g. vs 615 g.
Diameter: 79 mm. vs 82.6 mm.
Length: 106 mm. vs 112.8 mm.
(a 7-14 2.8 on m43 is comparable to a 14-28 5.6 on FF)

Although I would love to see lenses that are much lighter and smaller than my full lframe Canon lenses, I don't see it happen yet...

With apertures and shutter speeds we talk about in photography, I am almost sure photons come into the camera at a faster rate and in a greater number than rain drops into the test tubes, even figuratively spoken. There is no such thing as a non-uniform distribution due to that effect.

Nota bene: Rain collecting test tubes do not suffer from cross-contamination (not even due to a high gain factor).

nerd2: Good luck dealing with 2X cropping and resulting 2X resolution loss (per image height)

I agree with what you really wanted to say. There is available such a variety of excellent and superior native mft lenses: No need for third-party lenses on mft bodies!

So it's not 85mm equiv.

at nerd2: Sometimes I am amazed to see how some guys possibly come to a guess like this one. The 10.5's elder brother, the 25/0.95, performed 2.400 lw/ph equiv. 82 l/mm in MTF50P tests.

In reply to:

Mark McCormick: Lux is a value for illumination incident upon a surface. It means absolutely nothing as a product specification in this situation if we don't know what distance that surface is away from the light source. Are we talking six inches away from the light source, 1 foot, one meter, etc. I wouldn't be impressed at six inches. I would be impressed at one meter or more. This is a classic case of a corporate marketing department providing an incomplete specification.

To: papa natas
I'll give you one "^like" for that ;-)

It should read "Lumen".
"This is a classic case of a corporate marketing department providing an incomplete specification". I am glad you said it - I couldn't agree more. O, all these commercial, non-technical people, young trainees of great promise and jurists ;-))

The definition of CRI is defined by the International Commission on Illumination. There are exact regulations on how to calculate the value(s).
And yes, we have to rely on the manufacturers' data for today, as usual.

DPR please note that "the light has a Color Rendition Index (CRI) of >92" not ">92%". Their site says <94. There is no such thing as percentage; though the maximum possible value is 100. There can be negative values of CRI as well.

Fredy Ross: thanks. I went to their site and it didn't tell me more. For example how to use them

Their UK site told me that they are readily available. Their service told me that they will be available in Germany by mid of April.

I haven't heard about the Relio (Italy) LED CRI=94 Lights since months now. So I am glad that these Lumies will be available in due time.

In reply to:

Fazal Majid: The 92 CRI rating suggests these use Nichia 219 LEDs, which have more accurate color rendition than the more common and powerful CREE LEDs.

I hope they don't use PWM regulation circuits to do the dimming, otherwise the resulting flicker would render them useless for high-speed applications at anything but full output.

Their website says "without flickering"!

As a photographer, how can you possibly say that? For good colour rendition in photography, I consider a CRI- or Ra-value exceeding 90 essential. "Any LED torches" normally will have 75 or even less.

I also totally disagree with Aur who said "if someone recommends you a light based on CRI, run out the store and never come back". I'd rather say "if someone doesn't mention CRI or even doesn't know what is means, run out the store".

A high CRI or Ra is a sign of quality of the light source for still and video photography.

Thorgrem: Great field test. Seems like m4/3 is up to the task of shooting such a difficult to shoot sport.

I do agree. Including: 60fps, C-AF, HighRes - all done very convincingly!

DPR, your panel discussions are unrivalled. The way you look at the cameras, you take them into your hands and you talk about them, one can feel you really love them. Plus, what a wealth of information!

Having said what I said first-hand, the quality of the LEDs for video has still to be evaluated. Here and without further notes, anything can be possible ...

It's a true flash not a LED. You can expect their traditional color temperatures and usually very good color rendering indices. Of course, the values should be specified.
