On article Nikon D810 firmware C 1.10 now available (61 comments in total)

At the moment you find a bug in a piece of equipment you got your proof it isn´t bug free BUT it is impossible to prove any piece of equipment is really bug free.

I see an evidence of good work from Nikon to test their new product the fact all bug fixes announced above doesn´t appear as customer´s complains, at last in dpreview... From my side even after almost 30,000 shots I did not remember to face any of the "bugs" now fixed by this update.

Actually, to offer a bug fix for problems people aren´t complaining looks me an act of courageous. I applaud Nikon or any other manufacturer that act this way.

On article JPEG Committee contemplates adding DRM to image format (186 comments in total)

Oh no! I saw that before! Apparently they doesn´t know the nightmare it brought to video, audio and e-book markets...

Complete waste of time and other resources IMHO.

It must be much, much better than their legacy 20 f/1.8 that is useless bellow f/4 (in full frame) for its absurd sagittal astigmatism and coma, particularly visible in astrophotography but it will be there for any kind of photography, of course.

If that lens really could be used at f/1.4 with acceptable sharpness at full frame and controlled optics distortions, I am sure they would have a winner.

In reply to:

Augusto F S: This lens, Nikon AF-S 200-500mm f5.6E ED VR, does not come with crystal nano cover (2006 technology), but comes with integrated super cover (1970 technology). Could explain me why this regression? How is the correction of shadows and ghosts without coverage nano crystal instead of the old thecnologie (SIC)?

You get you pay for... how much do you think people want pay for it?

On article Sony reportedly shifting focus to full-frame cameras (455 comments in total)

They are focusing on 3k+ cameras and 2k+ lenses where the real money is (following Canon and Nikon). Companies are learning profitability can be more important than sales volume... It looks they can miss the lower end segment is a significant drive for the higher one. Well, let us see. Interesting future for the Photography stuff industry.

On article Winds of Change: Shooting changing landscapes (52 comments in total)

Very well done!

The images have something of character. It is not easy as most of the subjects are very explorated.

Congrats to the Photographer and dpreview.com to bring that to us.

Cool. Good idea!

Cool. Very cool.

Interesting... but it looks me a little bit big for backpacking.

Anyway ii is good to know you have an option to use filters also for some odd lenses.

It looks an interesting lens added to Canon great portfolio but I was wondering how the fans for f/2.8 zooms will receive that "slow" lens.

As a side comment, the shot samples provided by dpreview.com looks me better than the usual. Kudos for them.

On article Nikon releases ViewNX-i image browsing software (105 comments in total)

Very good job, Nikon.

It was the tool missed in my workflow. Better than Bridge I was using.

For me it is a great tool, it is fast. I liked specially the vision on map for my geo tagged photos, the menu personalization for "raw file open", the focus point display as well the interface - I really think it is the best GUI from any Nikon software so far. It looks they are learning something in the last years.

So far I did not have any hang up - but this is the first day of use yet...

They gave a DX version from D750, or close... I think there is people looking for something similar coming from D810, i.e., a "mini-D810"... the mythical D400

Cool ideas but weak implementation IMHO. It is an infant technology, perhaps it need more investments to be practically interesting.

On article Adobe celebrates 25 years of Photoshop (366 comments in total)

I started with Photoshop 1, bundled with BarneyScan we sold some in Latin America.

It was the first time a "mediocre" flat bed scanner could present some competition to super expensive drum scanners, thanks to the very good software embedded into it.

...just to complement the previous message: it is blaze fast. Faster than the previous version that was the fastest stitching program I had!

It makes, also, an amazing job stitching moving details as water waves or leaves under wind.

Kudos to Microsoft.
