hikerdoc: I bet it looked just like that when he put it in the bag to check through. I hope he wrapped it in something before he put it in the bag to avoid getting the glass shards in his socks and underwear.
You check an $11,000 lens when it is already broken and you are hoping for a settlement.

"I don´t blame him. I think you should take advantage of insurance companies whenever possible, they are one of the cancers of the modern world, so that´s that"

Yeah of course you should commit fraud and push up everyone else's premiums because you didn't insure it adequately. Nothing amoral about that whatsoever.

cosinaphile: while this is a very cool sensor ... I need a monochrome sensor in a Fuji body
so fuji why not offer it as a direct order from the factory ? ill bet you sell millions

@cosinaphile

You're massively underestimating the resolution of Bayer (or x-trans) sensors in general. In the very worst case (a scene illuminated by narrow-band red or blue light) then the resolution increase by going monochrome is 4x, but on average it is around 2x. This is because there are correlations between colour channels, the increase in the green value provides a good estimate of the increase in the red channel. So although your 24MP sensor only has 6 million red pixels, you can leverage a lot of data from the 12 million green pixels. The same applies for blue.

RubberDials: Eligible trade in cameras:

Canon 6DII

Lol.

If I had the money I'd buy a brand new 6DII just to trade it in (still sealed in box) :D

PhotoUniverse: Nobody is buying A9's, eh?

@ttran88 Because their profit margins are higher - fewer parts in camera, smaller BOM, reduced assembly/distribution costs. The sensors are produced by a different part of the company who sell to other manufacturers to recoup the development costs, so these aren't passed to the camera division.

All of this means they can run promotions like this to increase sales AND make more profit than the likes of Nikon, who are struggling at the moment.

People see this a sign that sales are struggling, I see it as a sign they have Canon/Nikon firmly in the crosshairs.

Nikonmaniac0620: Sony's trying to dish out as many A9's as they can before the ULTIMATE DSLR hits the market - D850. Once that's out it's the end of Sony.

I'm going to come back here 6 months after the D850 release and laugh at your prediction.

DesoloZantas: All they need is light sensors and pretty much it should be perfect, because light sensors could actually determine the distance between anything and what's on the same focal plane and what's not. It's pretty much with Lytro was doing but should be.

For Digital Cameras to advance, they need curve sensors, manual to autofocus mounts on the bodies (Reference: Techart Pro), they need a OS weather it's Apple or Android (Reference: Samsung Galaxy NX camera), better low light focusing and image quality, needs 15 stops of HDR (standard), and needs 5 axis stabilization (in camera and lens + digital).

** Canon needs to finally do 4k Mirrorless (cough*cough)

I'm not saying this is the only way to advance digital cameras but to push it further so it's worth having a Digital Camera over the iPhone. . . . . . .

Either that or everyone should be making light l16 concept cameras for all main camera brands (like Nikon, Canon, Sony, Pentax, Fujifilm, Olympus, Panasonic, etc.)

I presume by "light" sensors you mean lightfield sensors. Unfortunately these have resolution problems with the current implementation (pixel counts increase with the cube of the resolution, not the square), which would further exasperate the poor sensitivity of phone sensors. I don't think what you're suggesting is plausible until we have a better way of measuring the light field.

mgrum: Firstly computation imaging is just not going to solve the sensitivity problem, it's not just about how images look at 100%, in low light phone cameras take noticeably inferior images even without magnification. Once people start putting images on their 4K TVs demand for image quality may well go up. Smartphones will stop short of completely replacing the $500 ILC for those reasons.

Secondly ILCs are surely going to get on the automatic retouching etc. bandwagon in the near future. There's nothing a phone can do that an ILC can't, Sony have already made a foray into this area with PlayMemories. They can't compete on connectivity (without including a SIM card) but can work alongside your phone to provide this functionality. Again you can already do this with some cameras (send image to phone to upload to social media).

In the UK TV ownership is still growing YOY, and4K adoption is also increasing.

Geerlings: Camera Nostradamus has seen the future of low end ILC cameras! What a fresh new thought in the world of photography.

I have 0 interest in -ever- owning a cell phone camera w/ it's awful ergonomics and tiny sensor. And I've been looking at a large number of low end ILCs, some as old as 2012, to play with, just recently.

Guess I'm the one guy still looking to buy them over cellphones. Huh. Who knew.

David GranoDeOro: I've for years been arguing that entry level and mid level ILCs should adopt an Android/IOS system along with options to connect to cell networks for upload to social media. Sony of all camera makers should heavily consider it. I use the Sony A7ii and one of my frustrations is that I want to eliminate having to transfer the images to my computer for edits then upload online to social media and stock imagery and eventually to my phone for instagram.

Smartphones are great tools for recording memories but don't have the power to edit RAW files in Lightroom to the level of professional portfolio work let alone running full photoshop. The very best smartphones struggle with editing 24mp files from my camera let alone 200mp brenizer stitches. But then good enough for most isn't good enough for me.

Sony is already running Android on most of their ILCs, and you can transfer images directly to your phone to upload with the A7II.

migus: At least 4 factors concur to make the OP right in her oracular prediction:

1) The "good enough" factor, aka Pareto principle, aka KISS.
Is today's phone good enough as an entry-level dSLR/ILC replacement? Not yet. But it's getting there fast and unstoppably.

2) The best camera is the one you always have w/ you.
Guess which one is that? Right, a phone.

3) Versatility: Why do we always have a phone w/ us?
I need it for podcasts, mp3 and rarely for GPS. Others for tweets, snapchats, whatsapps, vibers, skype, email...
Others for WWW, or games... and some even for voice/phone.
A camera remains a single purpose tool, neither cheap, nor small, nor re-targetable (except when used as a weapon or door-stopper :-)

4) History repeats itself.
At every step the nay-sayers (including often myself) have underestimated the tech progress.
Next "camera... optical phased-array receiver, or OPA, collects the light from which it forms its image using a grid of devices called grating couplers."

"At every step the nay-sayers (including often myself) have underestimated the tech progress."

Not every step though, we have yet to see the much predicted paperless office, despite all the progress with email, laptops and tablets, here we are still smearing ink over sheets of flattened wood pulp.

Tech wont and can't solve every perceivable problem given enough time, it has to operate within the laws of physics, and the laws of economics.

medon78: "Abberation bug" sounds to me like a optical flaw.
In fact, it is some electronic communication issue with the EF mount / camera.

The lens is misidentified meaning the camera applies the wrong aberration correction profile, which has the effect of creating aberrations.

beavertown: Does filming video use electronic shutter not mechanical ?

There isn't one, physical shutters will be phased out as soon as electronic shutters become fast enough.

Sactojim: Good gracious these are beauties. The bar just got raised with this lens/cam!

They're nice, but I really don't see anything that couldn't be accomplished (at lower cost) with a leading 35mm system.

I bet you could take any image series tell half the people it was shot on "medium format" and they would rate it higher than the other half...

Mateus1: Colour rendering is great, you will not get such natural looking colors from X-Trans that look artifical and unnatural. The answer is simple: GXF and X-A3 on some pictures here have Bayer cfa, not X-Trans.

This is nonsense, the colours have everything to do with the type of dyes in the CFA and the postprocessing, and nothing to do with how the dyes are laid out on the sensor.
