On article HTC announces U Ultra 5.7" phablet with 12MP camera (38 comments in total)

surely anything under 6" is no longer a phablet?

On article CES 2017: Hands-on with Nikon D5600 (321 comments in total)
In reply to:

Sivakumar V: Right from D5200 to D5600 the changes are cosmetic. Not much of progress. Nikon could have introduced some of the revolutionary concepts from d500 in d5600. The present d5600 just serves the purpose of a new name and retention of the price line.

Sony has innovated much from a5100 to the latest a6500. Hope my favourite Nikon too does bring innovations from one model to other. Canon has shown new mirrorless EOS M series periodically and even given new lens now. But Nikon's mirrorless is in a very small sensor format.

I believe this is because they are protecting the higher models, and there's not been a huge amount of innovation there.

Nikon still continue the old market segmentation practices by putting limits on each range's features. For example, the D5xxx has quite a low burst speed, for no good reason other than to protect the higher models, which shows a lack of innovation.

On article Handy tool helps you say no to work for 'exposure' (83 comments in total)
In reply to:

HRC2016: I don't see an issue with doing work for exposure when you are starting out.
When I was starting out I sought out opportunities to work and make contacts. Yes, it did lead to paying gig and a great career. Were the people I worked for likely to hire someone for pay? Probably not.

I am skeptical of doing work for many charities. It depends a lot on the kind of organisation. If they're all entirely volunteers then I might work for free, but many charities are run along commercial lines, and some charities pay their directors and senior staff quite well:

so I would not do free work for the Red Cross.

In reply to:

PPierre: I remember when my girlfriend asked me what was the best between getting a raise in salary or getting a higher position in her company. My opinion was that the raise was more preferable : for a company, money is the key objective. You don't respect someone you don't pay. A company will always save its money for what it thinks is really important. If they don't pay you, but give you an important role / exposure, it means you're not important enough for being paid : this is not respect. Money before honour. In our capitalist world, and for companies, anything that's not paid doesn't have any value.

totally agree. I once worked for a company which was clearly going to go out of business as the money was drying up. After making half the staff redundant, they gave everybody left a job title promotion to make them feel better, but of course no extra money.

On article Canon patent shows curved sensor design (105 comments in total)
In reply to:

Roland Karlsson: This is not likely to come - at least not soon. I can see some theoretical advantages with the totally curved sensor. But this partly curved one - how the &/&%¤ to design lenses that are sharp on that surface? The totally curved one is too expensive though.

Moreover, a flat one is universal, but a curved one is custom made, for one lens only. Is that a good idea?

virtualreality, I'm not sure whom you are criticising.
Anyway, it's all about physics, or optical physics and geometry. it's about the shape of a section of a sphere and the focal distance from the lens.
In practise, lenses are designed to focus a certain distance behind the mount, and that's common to all lenses and bodies of a particular mount. It's engineering.

the focal plane, or in this case, the focal section of a sphere, is always at the same distance from the lens mount, so I don't see why a new set of lenses couldn't be put on sale which take advantage of this new design.

In reply to:

Michael Bonocore: 4) Morocco is not the easiest place for a photographer. In India, I had people lining up to have their photos taken, and hardly ever got turned down when I asked for a portrait. People there were very open to having their photo taken. Morocco is the exact opposite. There were SO many incredible scenes and people I met that I have no photos of, because they would not allow it. The culture is very protective of their privacy. Honestly, it can feel very uncomfortable walking around a Moroccan city by yourself with a big camera and a lens. The people may feel you are taking advantage of them, and I try as much as possible to attempt to engage in conversation with people I take portraits of, so if I am close to them when I talk to them, I can get a nice portrait with a 35mm, or in this case, an iPhone.

Cont in next comment.

In some countries they feel uneasy when anything is pointed at them, presumably because being shot is a real risk.
Consider getting a right-angle mirror attachment if you want to take candid photos.

On article Nikon reportedly eliminating 1000 jobs in Japan (518 comments in total)
In reply to:

tommmee: I let go of my d800 and all gear in february this year for a Fujifilm mirrorless system that I had used for two years alongside my nikon setup. Month after month I reviewed raw file after raw file and found that side by side there was so little difference in quality and that in mirrorless I could preview all images before capture that the nikon system became inconvenient. And this was comparing crop sensor to full frame. The Fuji is so much easier to catch improptu moments as well as images with an hour of setup. I wish nikon would reconsider their reason for being and look at mirrorless full frame seriously as their future system.

I agree, the advances in sensor technology mean that there's no real-world gain in going for a 35mm sensor.

I have a friend with a high-end Nikon. For quite a while he was working in a very pictureque city. I asked him how often he took his camera to work, and he did so very rarely, it was just too heavy to lug around all the time.

Meanwhile I went m43rds mirrorless, and I really do take my camera with me nearly everywhere. So much so if I don't have my camera bag with me, I feel there's something missing.

Sure, if I compare my friend's photos with mine at the pixel level, they're better, but how often does every pixel matter?

OWC aren't Apple.
Hats off to OWC for getting in quick for this new market.

On article Throwback Thursday: Olympus C-3040 Zoom (119 comments in total)

This was my first digital camera. Soon after buying it I sold my Canon EOS100 film camera and lenses as Canon seemed to have no interest in making a DSLR.

I'd waited a while before going digital. The key feature was the quality had become good enough, and sufficient resolution to be able to fill a 1280x1024 monitor even after cropping. The C3040Z made great images, and it had loads of features, apart from the size and non-changeable lens, it competed well with the Canon I had.

However, the shutter was laggy, like most cameras of their day, which meant you needed to be an expert in anticipation. After quite a few years of good service, I replaced it with a Canon A710IS, because I'd bought my wife a Canon Ixus 710, and it was so much quicker to operate.
The Olympus was still going strong, and I gave it away to a friend who really wanted to go digital but had no money, and since she mainly wanted to do still lifes, landscapes etc, the shutter lag didn't matter too much to her.

I would have been partly ok if they only fitted a micro-sdxc card slot, because you can use these in your camera with an adaptor (though there can still be a speed discrepancy with regular sized cards).

The way I see it is that the MacBook pro is really an up-spec Air.

Apple's problem is that although they have made the Mac ever more popular for consumers, they are ignoring the professional "power" users, and it is they who promoted Apple and encouraged others to use then because they were easy. When the pro's switch away, the people who seek their advice will follow.

the best remedy?
buy a cheaper phone and spend the rest on a proper camera and with the change buy a book on how to use a camera!
You can buy last year's base Nikon, Canon, Sony, Olympus or Lumix camera with a kit lens for half the cost of these top end smartphones.

Mark Turney: It's funny, my Apple iPhone 6s Plus doesn't have a lens flare issues. Neither does it explode, nor does the sapphire glass over the camera break spontaneously, nor does the screen crack with the slightest drop.

Figured I'd give some kudos to Apple for what they do right. All I ever see is Apple bashing ....

no, iphones have never had a problem with flare. oh wait...
