On Behind the Shot: Watery Grave article (91 comments in total)

Very informative and a nice picture, of course.

I have a question: why add an ND filter to increase exposure time even more? How does this improve the looks of the picture?

(I know you mentioned the blur of the fish, but that was accidental, not?)

On Massive $33,500 2450mm f/8 NASA lens surfaces on eBay article (235 comments in total)
In reply to:

Frank_BR: This Jurassic lens comes from the film era, when anything less than 6x6 was considered small format. Then digital photography came along...

More than five years ago, Michael Reichmann from Luminous Landscape showed that a digital camera Canon 1DS with "only" 11 MP produced a more detailed image with less noise than a 6x7 film. Today, that the digital sensors are even better than in 2009, a good m43 camera can equal or exceeds the 6x7 film format.

The m43 sensor has a crop factor of about 4x in relation to 6x7, so a modern 600mm lens adapted to a m43 camera should overcome the NASA monster of 2540mm. Besides, if you consider that a CMOS sensor has sensitivity 50 ~ 100 times higher than a 6x7 film, then it's clear why NASA discarded this monstrous lens long time ago.

Another problem is 'data rot'. Vinct Cerf, one of the founders of the digital age warned for it, not so long ago:

It is likely people of the future won't be able to open our digital files, or it will be far to timeconsuming to sift through the thousands of pictures each individual person makes, right now.

You better have a good EVF in order to be able to nail the focus with this lens wide open. Focus assist and zebra won't be 100 per cent neither. Maybe 3 out of 100 dpreview users will be able to use this lens in real life, just because for the others, their eyes aren't good enough.

Belgium has 'French' fries and the saxophone, and of course the best beer in the world.
Why on earth does the UK have a 'National Media Museum'? Can you name just one respected UK photographer, dead or alive, that wasn't a drug addict or alcoholic?

SDPharm: > Kowa announces pricing for three Micro Four Thirds lens

So, what is the pricing? Am I missing something, or DPR is trying not to be helpful?

Just another article re-writing text they found elsewhere; who cares about good coherence of a tex? Hide the essential information refered to in the title deep down into the captions so it is hardly noticable... Mentioning "TV distortion", but carelessly not explaining it... that's just a lazy text writers's mistake.

These lenses require excellent EVF in order to nail the focus, or an external monitor. I wouldn't want to use these on my GH3...

Also, I guess the caption writer works for a fashion magazine as a second job, because he/she pays way too much attention to color and style .-)

Ivan Lietaert: I actually like this kind of video. It is quite convincing.
There is one thing I wouldn't do, and that is to change lenses that close to the surf. I'm sure the your sensor will get dirty very soon like that!

I don't have a problem with the presenter being on the Sony payroll. So many people have more than one job, these days, just to get by. Even if the photographer was on Sony's payroll, I would still find this an interesting video. I strongly believe that the majority of viewers are capable of filtering out the marketing babble.
I really don't see what problems you can have with this video. Its core message is that you can make decent sport action shots with a camera and lens costing less than a thousand dollars. Why on earth would anybody start spewing vitriol on that, unless one is a cynical troll... There are better place to do that... a therapy room, perhaps?

There is nothing cynical in this piece. Conversely, there is a lot of cynicism in the comments under it. The A6000 has been called a good camera by many professional reviewers. Eoshd for instance: "The A6000 is certainly Sony’s best performing mirrorless camera yet for video with an APS-C sized sensor." It is nice to see this camera in real life use.

Rick_Hunter: KEN ROCKWELL USES THIS. (enough said)

We are looking at this because this company decided it needed to sell this app on the back of young models. They chose to push this model's skin forward. We react.

ShatteredSky: Plastic fantastic. Why everybody wants to fake anybody's face is beyond me ... cloning out a pimple is one thing. Smoothing over the entire facial landscape is another.

Exactly the same words came to my mind... plastic fantastic. This model is beautiful in her natural state. Perhaps this model doesn't care, because she got paid for this picture, but thousands of other youths must feel depressed after seeing this... Apps like these should be banned, just like anorexic catwalk models, male and female.

I like the picture, actually. It does stand out compared to the thousands of other 'light beam' pictures, due to the figure in the dust.
It seems to me that many of the critics here are simply jealous.
Also, it reminds me of another Australian photographer who got in trouble for manipulating his pictures: Frank Hurley. Check this picture: http://picturesofworldwar1.com/photographer-frank-hurley/death-the-reaper

Not so sure about the hair style, but the noise reduction is quite impressive! Better than the GH3.

On 'See Impossible': Canon counts down to... something. article (1656 comments in total)

A conceptual idea based on the mispronunciation of the word 'the'??? Having the Canon website hacked by an international hackers consortium would have been better than this...
What a waste of budget in these dire times. Who ever came up with this should be sacked instantly. What is happening to Canon? While other brands like Panasonic, Sony and Fujifilm bring innovations every couple of months, it has been years since canon brought something exciting to the consumers. Waving a definite goodbye to the Canon brand this moment...

Ivan Lietaert: Is there anything out there like this for Android and Windows phones?
It would be a testament to credibility of Connect if the author would at least research this, and mention the outcome of that research.
Now, this article is just another plug for the iPhone; an ad disguised as an article.

Before I read your responses, I tried to find a similar app for my Samsung Ativ S Windows Phone. I know this phone is an abomination, according to many, but I love it. I found it hard to find a similar app. In the end, I found the app ProShot, but it failed to install on my Ativ S. Don't know why. My wife owns a Lumia 625, so I'm going to check out the camera app.
It is a testament to the credibility of the author, Lars Rehm, to follow this up and to provide the information about the competing phones. Thank you.
