Elaka Farmor: The water-color-effect even at iso 125 is not pretty…..sadly

Indeed the jpg quality is appallingly bad. Worst results I've seen in a very long time including smart phones. Did they accidentally enable a water painting filter!

I'm already waiting for the much improved Nikon AW2 and some extra lenses.

npires: I was just saying to myself I should do more macro shots and then I see this! Brilliant! Has given me some inspiration :)

You can get some decent shots of scales with the Canon MP-E 1-5x @ 5x.

What's the effective NA of the lens which is what determines resolution? Really massive aberrations around the periphery of the lens. But still a nice idea that will only improve with time

On Up close: The beauty of butterfly wings article (47 comments in total)
In reply to:

peterwr: Little-known fact: the irridescent colours of butterfly wings are produced not by pigments, but by nanometric structures on the scales' surface that reflect different colours of light, much like the microscopic pits on a CD.

God, I love nature.

Not all butterflies have structural colour and indeed most do have pigments. How for those that have special scale structures which are photonic crystals the interplay of light and the scale causes interference effects which can can lead to certain regions of the visible spectrum not being able to propagate through the structure. These colours are reflected, while other colours can pass through the scale. These so-called band gaps are highly directional, so it depends on what angle you view the wing as to what colours are reflected and absorbed. If at a certain direction red and green can pass through the wing, but blue is reflected then you will see a beautiful shimmering blue. However at another angle the blue can pass through and maybe a fraction of the red and green is blocked leading to another colour entirely.

The most famous butterfly for structural colour is the blue morpho of South America.

For the man with a little iPhone you can now feel adequate again by attaching a big lens. I just can't see the turtle neck wearing, latte licking, bean bag reclining hipsters going for this.

In reply to:

Scott12345: Using a second lens to capture depth information to map back depth of field and other possibilities.... could be the biggest innovation in cameras since the invention of the CCD.

Doesn't make it it more amazing. We've had twin lens cameras from the likes of Fuji and Panasonic. Now they were after a 3D effect but HTC is using it for a depth map. Once you have a depth map you can do all sorts of cool things. The holy grail is to be able to create a depth map for video applications.

In reply to:

JWest: How come they can cram 2560 x 1440 affordably into a phone, when I can't get my hands on a decent quality monitor any bigger then 1920 x 1080 without spending a small fortune?

Because it would almost impossible to scale this pixel density up to a much larger device and not have huge issues with dead pixels etc. It's like in the early days of digital when Canon released 1Ds, the yields from a FF sensor were dramatically lower than crop sensor with as much as 50% failure rate and hence the high cost.

Now of course you failed to mention we have just seen the release of 4K monitors @ 24" size that are reasonably affordable, but these are still only about 200dpi. 531dpi would be higher than even 8K. We will see this happen but not for many many years at an affordable price point.

Except for the the fact it's an old idea and has been used for a long time in the field of depth estimation. It's called depth from stereo and is basically how our own visual system works.

We're used to being ripped off and getting second class treatment. But this sets a new high mark on the sphincter scale. Can't wait for the a3700 with 19-45 f/4.5-6.3 kit lens for $599.

In reply to:

KonstantinosK: Many photos at 12800 ISO, and, is it me, or are they look very good and detailed?

I agree, jpg quality is very ordinary even at ISO 100 and at ISO 3200 very little detail is left. Poor jpg engine and I don't think the lens was great, especially in the corners.

On Hungarian law bans photos taken without consent article (321 comments in total)

So I'm on one side of a river photographing scene on other side and some one walks into scene and I think they provide a nice sense of scale, take the shot, then madly jump in my hastily crafted raft, paddle to the other side, chase them down and get a written consent from them.

I guess I'm not so hungary for travel anymore.

You know things are bad when the Chinese find your behaviour corrupt. This has been a bigger fiasco than the Canon 1D III AF saga. At least they eventually accepted the findings and fixed all cameras free of charge.

Well it's a whole $69 cheaper than Tamron's 150-600, so that must count for something, anything, hello is this mike turned on?

Nikon living in cloud cuckoo land with their pricing.

Should have just stuck to offering an UW version of the 1 series

On CP+ 2014 interviews: What we learned article (93 comments in total)
In reply to:

kongqueror: Just curious - why no interviews with Sony? Would have loved to hear from them.

Really, have not seen a single Sony A7/A7R on the streets yet. It's no more disruptive than any other mirrorless camera. Can't wait to see how disruptive is it when people want to start using big heavy fast glass on the camera, something Sony has been very careful to avoid by releasing small fairly slow lenses. The most enthusiasm I've seen is from people who use third party MF lenses from the likes of Zeiss, Leica etc and Canon users wanting to use their glass on an excellent sensor.

On CP+ 2014 interviews: What we learned article (93 comments in total)
In reply to:

venancio: I look for revelations in each interview, whether there is that "you chose us, we didn't choose you, deal with it" attitude, or that transparent concern that displays affinity to customers. If the representative can't do but mouth corporate talk, at least the first attitude immediately displays itself so it gives you that period of adjustment or time to think about alternatives. The future is important, so I want to know where they're taking me. Don't want someone whose vulnerable to the Nokia syndrome, someone who does not believe that change is coming, or not prepared to respond to the change, even if it is dictated by consumers' needs and not by company vision/profit statements.

You must also understand the Japanese can appear very aloof and it's very hard to get a read on them. They give almost nothing away by their mannerisms. I say this as someone who works for a Canon R&D company and has many face-to-face meetings with our Japanese partners and have left many a meeting not knowing what they thought. Were they happy, angry, encouraged? Often you don't know until you get an email a week later what they were really thinking.

Photato: If Smartphones killed the P&S, I wonder what killed Nokia, Blackberry, HTC Motorola and hurting Microsoft?
The current state of the photo/video industry is rather boring.
It needs a player to shake things up.
Canon in particular seems to have stalled, reminds me of Microsoft, just getting by confident in its comfort zone update after update.
Currently the market is so saturated and mature that from now on it'll be more commodity replacement rather than have to have it upgrades.
But there are still lots and lots of exciting things that can be done.
The industry needs a visionary, enthusiastic, creative company.
Give us some magic and you'll get our money.

Indeed, but another worrying trend from Canikon is how expensive it has become to own good gear. Superteles that were already very expensive doubling in price and costing more than cars, nearly all L lenses showing massive price rises with new generation, Nikon very similar. Photography once again becoming a rich man's game.
