In reply to:

Quantum Scientist: Early on in computing, Apple was THE computer for graphics and design professionals. It is now painfully apparent that Apple has abandoned the professional and turned to selling iPhones and iTunes music to gum-chewing dweebs with tattoos.

actually, many young people only think about whether a device is an Apple (iphone or pad) or a Samsung or other big name. It's unlikely they could explain anything specific technical difference about the differences between iOS or Android.

I think something went wrong with the hotshoe.

Fog Maker: As long as people are not talking about real versus fake bokeh I am satisfied- bokeh is just an optical flaw. Period.

Ending a sentence with "Period" doesn't mean you're correct, it suggests you've made up your mind right or wrong (in this case you're wrong) and aren't prepared to discuss it.
So why bother to write it in a comment on a public forum?

Olifaunt: And where is Google's culpability in all this, the entity who has probably actually made the most money out of the others' unpaid intellectual property?

all images are copyrighted. sometimes it's hard to tell who controls the copyright, either because the image never had a copyright watermark or meta data, or because the intellectual property violator removed it.

you can easily stop Google and legitimate search engines from indexing your website using the robots.txt file to tell them not to.

In reply to:

so-what-17: Ya for someone who does a lot of cropping, bigger is better..and of course lenses make the difference too.

ah, Jacques Cornell, the megapixel myth.
there's no point in having more pixels than the resolving power of the lens, which is a function of the lens' diffraction limit.

xPhoenix: There are tricks (like computational photography) to give a helping hand to small sensors, but until we can find a way around the law of physics, a big, honkin' sensor is going to be best. As they say in the car world, there is no replacement for displacement.

but you also have to consider whether you want torque or power

MrBrightSide: As usual with these "everything you know is wrong" videos, the dude completely misses the real point of his little demo. The purpose of changing focal lengths is to change the size of your subject in relation to the background. If you want more background—like with an environmental portrait, use a shorter lens. If you want less background so that viewers concentrate on your subject, use a longer lens.

its all about the distance between camera and subject and not about the lens in use. changing the lens allows you to change the distance between camera and subject.

Anulu: Field compression caused by narrow angle of view. In the video at 1:23 when he croped in to the image he changed the angle of view on his photo.
The narrow angle of view force you further away from the subject yes, but the angle of view is specified by the focal lenght of the lens, so actually the compression caused by the lens.

No, if you don't move the camera, the scene it can see doesn't change, you just select more or less of it according to sensor size and lens field of view

yes, but that's just cropping.
the scene in front of the camera is not affected by the lens magnification/field of view. by changing the sensor size or lens focal length you just choose how much of the scene to capture (assuming you have a perfect lens).

A corollary of this is that the perspective in a photo is not about the sensor size!
It doesn't matter if you have a phone camera with a tiny sensor or a medium format sensor camera, if they're the same distance you get the same photo (with suitable cropping).

No mention of licensing fees, patents and other proprietary lock-ins?
Before I even went near a standard like this I would ask some intense questions about licensing - pay for encoding, pay per encoder, pay for decoding, pay per decoder, pay for different features? These fees can get pretty big depending on the contracts.

PhotoRotterdam: Be thankful for the people who dedicate their life to follow their dream to build something that might leave us scratching our heads, but nonetheless will someday inspire others or evolve into a product that fills a niche.

I once had a technical camera workshop (with film) and I thoroughly enjoyed the slow capturing proces. This is the first time I see a digital back for a technical camera. You may ridicule it, but if you look back in photography history, you will see that some photographers have created wonderful art by making use of what a technical camera can offer. Something you simply cannot do with other camera systems or in post (except rendering it, but I don’t know if that still would count as a photograph)

yes, if you mean "full frame" is where the image capturing device (whether film or digital sensor) is the same size as the final print, this is indeed full frame.

hypnotictortoise: I was thinking about this problem the other day, and was wondering why nobody has used commercially available sensors, and combined the output signals computationally.

That was probably poorly expressed, but I'm thinking the same sort of thing as the way they do arrays with radio telescopes.

Meh, I ain't no electrical engineer, but it seems like a good idea.

you mean like this? https://en.wikipedia.org/wiki/Very_Long_Baseline_Array

finally, someone worthy of the term "full frame sensor"!

howdya feel now, all you camera snobs with your tiny 35 mm sensor DSLRs?

:-D

@Sion H, yes, and animal welfare regulations are being rolled back.

On article Opinion: the Sony a7 III could be the new Nikon D750 (1233 comments in total)
In reply to:

speculatrix: In my experience Sony are good at design and manufacture

Their after sales service is poor, and if your unit fails out of warranty you're going to have a big expensive problem getting it fixed in a reasonable time at a reasonable price.

Dpreview, please try a test where your act as a mystery shopper to assess after sale service, with and without warranty.

I've had a few Sony products which need out of warranty service, and they basically say "send it in and we'll assess it and charge for that, then we'll tell you how much to repair it, and you can pay for just the assessment and get it back still broken, or we can scrap it, or you can pay for repair". This is even when it's a standard process like swapping the fan in a laptop (a $5 component).

Here in the UK there's a lot of fear that a trade feel with the US will cause a significant erosion of our high standards of farm animal welfare.

In reply to:

Spectro: PETA overall is a good organization, their idea and concept. I think they went overboard on this case, lost some common sense. Somebody up top there, got over zealous on what is animal rights.

PETA may have started out with good intentions but there are so many terrible stories about them that I think a lot of support for them has disappeared. This might have less to more extremist behaviours which have accelerated the process.

In reply to:

Garug: I have MacPro and MacBook Pro. The MacPro has been serving well for 5 years still ok, though very disapointed it has not been offered any updates, like up to date craphics cards.

My MacBook Pro is long outdated and today Apple does not have any offering that I would be interested in, only toys that do not deserve the Pro marking.

Sadly it is bye bye Apple.

even the keyboards on their macbooks seem designed to put off professionals.
