On SerraDoAmolar-Final1 photo in Osvaldo Cristo's photo gallery (1 comment in total)

Serra do Amolar is a rock formation in the middle of Pantanal region in Brazil, near to Bolivia border. Pantanal is an enormous swamp region, so as expected is a boring flat region, so such ridges really call the attention when wandering there.

I made that panoramic stitching 30 shots in portrait orientation. The odd in the technique is I used my telephoto zoom lens instead of WA. I used Nikkor 80-400 at 80 mm and f/16 for better IQ.

One more promise to replace JPEG. Let me see how many times I saw that before... lost the number!

On Nikon announces AF-S Nikkor 20mm f/1.8G ED article (67 comments in total)

It looks Nikon is releasing a good lens at a reasonable price point. If it maintains coma under control, it certainly is a great lens.

I was considering Rokinon 24 to replace my Sigma 20 f/1.8 but this new release can be a better option. Let us wait for the reviews....

Just another Canon shooter: It would take zillions of monkeys and zillions of hours to type a Shakespeare poem - but just one monkey and a few seconds to beat zillions of photographers.

You made my day! LOL!!

Strange... but interesting idea/concept. I can imagine some applications for that set up. Anyway it is not for me...

In reply to:

Rutgerbus: Very proud to see two of my pictures (#1 and #2) in this Readers Showcase. The Crown on my work. Thanks you DPReview staff.

And that with Nikon D700....the oldy. Hopefully this shows that in the race for a better picture you don't really need that MP beast to take good photo's.

Congratulations! I love to see people making great photographies and you certainly know "a few things" on this!

On Chinese government orders Nikon to stop selling D600 article (228 comments in total)
In reply to:

HK photographer: Nikon made anouncement to tackle the D600 problem after an US law firm started to gather D600 customers for collective action (it's in the news last month).
Chinese customer protection department didn't pay attention to D600 until some Nikon dealers blamed the D600 sensor problem to the smog, not to the camera. General manager of Nikon appeared in Chinese photo web to clarify the issue afterwards but Nikon China had done nothing to tackle the D600 issue before that -- there was much delay than their action in US. That's why the Chinese felt the discrimination. Same as when Toyota recalled their cars in US few years ago but left the Chinese buyers alone. At the end, the CEA of Toyota had to go to China to apologise.
I nearly bought a D600, so I have been following up the issue of dust. Nikon has been dead slow in admitting its own problem. Nikon, you can only blame yourself. Sadly, some people here have taken this chance to air their view against the wrong target.

" never bought anything Nikon since the 2008 Wenchuan earthquake. Back then Nikon was gaining ground by leaps and bounds in China, yet they donated a mere 1 million to the quake affected area, while Canon donated 10 times more " - so that is your reason?

Did you have the idea Canon is much bigger? Actually according to the 2011 figures Canon revenue is 6 times bigger and net income is almost ten times!

...and you? What was your donation?

I think there is better and sound reasons to be considered, as the obvious miscare and prejudice against some "minor" markets.

On Nikon 1 V3: a quick summary article (596 comments in total)

I cannot understand the common complaint against the size of the image sensor: it is almost irrelevant for most applications. Just give good IQ. Shallow DoF is one of the applications where bigger sensor helps but usually it will require a combo with big aperture lenses, it means big size and deep pockets to afford it.

The current image sensor used into Nikon 1 series presents quite decent IQ, I would expect the new generation will present yet a better one.

Certainly I do not see it as a "fit all" camera, but certainly could fit the needs for most one, including a number of people bashing it for its smaller sensor than a DX or even for a FX!

In reply to:

McJ: If this was a dslr, it would have been panned as the worst performing camera of the last 10 years. But since it's mirrorless, it magically gets "gold".

I will probably buy this camera myself as a slow digital back for my 30+ year old primes, but I feel sorry for those that buy this as a general purpose camera because it got "gold" in this test.

/If this was a dslr, it would have been panned as the worst performing camera of the last 10 years. But since it's mirrorless, it magically gets "gold"./

I had exactly the same impression. It is the price paid to sell advertisements for mirrorless.

On AP cuts ties with Pulitzer-winning photographer article (166 comments in total)

The rules were clearly stated and the author knew them, so what is the point? I think AP has to afford their own and public rules in order to their customers (the picture´s buyers) know exactly what they are purchasing.

It is not a question if the rules are fair or not - they are agreed rules between the agency (AP), their customers and (it is expected) by their Photographers.

For me it is not a journalism Ethics issue, but a business Ethics one.

On Want to remember something? Don't take a photo article (183 comments in total)

"But a new study, published in Psychological Science, suggests it's possible that the act of taking pictures may actually lessen our ability to recall the details of a subject." - really? You do not need a PhD do know that!

Except for a few pictures I take from social events, virtually all my pics are made for artistry reasons - not I am an artist! I never bought that idea to "document" the life.

I never used such card but since I saw their advertising years ago I had understood that functionality was standard!

Anyway I have no interest on that Mega slow gimmick.
