Is there an easy cure?

Depends on what the disease is. Can you get hold of another flash to debug if the flash or the camera is to blame? Did you test if the flash still works as an optical slave w/o repair?

Is it worth sending it in for repair?

Hardly, at least with the cps service prices around where I live. Look at the 430ex2 prices on ebay and decide.

It's a nice flash, but 430ex2 doesn't have rt capability, and you get "big" 600ex flash clones from 3rd party manufacturers very cheap these days. Unless you positively want a "little" flash w/o master capability, get a new one with warranty.

The possibility of having a universal format with the new 14 bit per color is interesting. But the success of a JPEG substitute depends on its adoption by Lightroom, Photoshop, Windows and Mac OS.

Photoshop had plugins for most aspiring formats, to no avail. Adobe learned from this and Lightroom is very limited, supporting no output plugins unless you code lua to call ImageMagick. Windows or MacOS are no apps, and I guess few photogs care about what their built-in viewers support.

The real test for widespread picture formats are the web browsers - and for example here mng failed big time to replace gif even if there were very good reasons to do so. With more and more devices supporting browsers, it'll get even harder to adopt a new standard.

However, for users to change their workflow, saving the processed images in a new format, it would be good that Canon and Nikon had this format option, in addition to JPEG and RAW traditional.

Following that logic, you'd have a choice of jpeg-lossless/jpeg-12bit, jpeg2k, webp, jpeg-xr by now. Of course all have to be supported ad infinitum to protect customers' libraries...

Seriously, soon enough all this talk of "you need f/2.8 to stop motion" is going the way of the dodo.

No, it won't. In times of the original 5d1, you needed f2.8 to stop motion. In times of the 5d2, you needed f2.8 to stop motion. In times of the 5d3., you need f2.8 to stop motion. In times of the 5d4, you will need f2.8 to stop motion. Get the picture?

Wait, there is a MASSIVE difference in image quality between the 5DII and 5DII?! Since when?

Who said anything about massive? But it's significant: The 5d2's images respond not as well to denoising, and the noise pattern is visually more disturbing. Then there's a slight increase in snr, and some less banding (while not at 6d or 1dx level).

But if used properly, this won't matter as you can create visually stunning images with the ff 5d2 - there's no real need for the 5d3 features if you shoot the 5d2 with the purpose in mind it was designed for.

I'm no flash expert, but I've fired a remote 600EX-RT with a camera-mounted 90EX. I assume that's optically?

Yup, Canon was kind enough to have the 90ex work as optical master, just as the pop-up flashes ... while the much more expensive 430ex2 and similar, well, kind of miss it.

No AA filter = not positive for anything but the company making the camera (AA filters are very expensive optical devices).  Removing it does not help image quality, and it does hurt image quality of still images.

Not exactly, but you should really know what you're going to shoot and if you can make use of the (tiny) difference. See the Internet photog review authority on that on the d810, "missing" both the aa filter *and* the optical low pass filter:

The quality produced by the 35mm f/2 IS is noticably better than the 17-40mm though, at least in my humble opinion.

I find the iq of the 17-40L leaves nothing to be desired if used properly and with the purpose the lens is intended for. It's not a pj's run and gun lens though (get f2.8) or for low-light handheld in general (get IS)

Technical Support / Re: Repair or Return?

The reason to return it is because it failed their QA process, which is rather disappointing, and because I should have to be the one to pay for the shipping to send it in for repair.  I can probably negotiate that with them, though.

Ah, right, I forgot about this as a cps center is right around the corner from where I live :-o ... but I hope they'll cover the shipping.

The other reason is that now that I have a fisheye lens, I'm not sure if I really like the look.  Obviously that's a whole other issue and one only I can sort out.

Indeed, and lacking such a lens I really cannot there. Which doesn't mean I cannot have an opinion :-p ... with the current plethora of first class uwa lenses I imagine it needs a good reason to resort to so much in-vf distortion and usability hassle plus post-processing defishing loss of sharpness (if you do that). Let us know how you decide!

I do think that its time for a improvement, for color corrected web browsers, etc.

I don't get that - why is a file format change necessary, my understanding is jpeg/png work with embedded icc profiles just fine (or jpeg with the appropriate tags for srgb/argb)? The only problem is that chrome's color management is broken atm.

Even with the outer points the focus is sharp. Don't know how the guys above can have such a bad experience with it.

With proper usage, the 6d will give you tack sharp images with every af point.

There have been a number of potential replacements for jpeg, most notable flop was the jpeg2000.

Not quite, it's used a lot in video processing as individual compression of frames. But for stills, you're correct - all these potential sucessors lack the "killer feature" to replace jpeg, the last duds were Google's webp or Microsoft's jpeg-ex. Having transparancy obivously doesn't cut it, the web still uses png as transparancy in *large* images is not common.

this is interesting, not sure where I'd make use of it altho it would make storage of my processed, finished files a bit smaller, perhaps.

The 14bit color depth (like current dslrs) indeed looks appealing - but it won't make a difference for final exported images. And then the jpeg supports 12bit for a long time, and which imaging apps outside niches use it? Right.

Otherwise, bpg (h265) is about the same as webp (vc8): A image format based on a video compression. Nice space saving, but who cases in times of cheap hd space and fast Internet. But bpg doesn't have a worldwide enterprise supporting it. This basically means "forget about it".

What would you do?

What would be the reason to return it anyway? If you get it repaired, they might even take the time to clean and calibrate it again (there are some spots on the front, even if most likely they won't show up on the shots).

EOS Bodies / Re: Sony Sensors Coming to Canon DSLRs? [CR1]
« on: December 17, 2014, 12:09:18 PM »
Proprietary tech, pride, 'the Canon Premium', etc. all tip the scales very heavily away from bringing in Sony to assist.

Fyi: This isn't about pride, it's about making money. So on the one hand, Canon would get a dent in the "tech leader" department, but wouldn't loose a whole market segment. And if Canon's own high mp sensors would be clearly inferior to Sony, the loss of reputation would be even larger.

I find the Apple switching from PowerPC to Intel quite valid - they have their image and MacOS, Canon has their lenses, service, and usability that will keep users from jumping ship just because the sensor is the same.

Lenses / Re: Help me decide: should I buy an EF 135L
« on: December 16, 2014, 05:40:31 PM »
It always produces the finest images. I own the 100L and it's a great lens too but the 135 is far better in almost every case I need.

How's that (and very nice shots, btw)? That's an unusual opinion from someone owning both, so could you please elaborate what it is you need, i.e. where the 135L is "far better" than the 100L?

EOS Bodies - For Stills / Re: Canon EOS 6D Firmware 1.1.6 Released
« on: December 16, 2014, 05:13:06 PM »
I hope you guys are having a better experience than I am, but i cant work with this any longer.

Nope, at least I haven't :-\ ... the outer points give you bogus af locks, and that's that.

But let us know if multi-af point tracking has improved significantly, if so maybe it's worth to bug someone over at Magic Lantern to adapt ML to 1.1.6.

Fyi: I tried to port the 5d2 ML method of "af patterns" to the 6d (i.e. chose not all or one af point, but for example the right three for portrait format tracking), but Canon has removed the relevant firmware part on 5d2->6d :-\

Fixes a phenomenon in which the camera may not first use the center AF point to focus, when the AF point selection is set to automatic in AI Servo AF mode.

This is indeed an important bugfix, for once - the 6d was known to ignore the best center point and is (was?) abysmal in multi-point af tracking.

Question is how much better it has gotten, as this is a hardware limit: The outer points often fail to get a af lock or (worse) produce a false positive af lock and will feed this bogus information to the firmware. I imagine even with this fix, the 6d is still center-only.

Most important: Magic Lantern will not run with this update, and there doesn't seem anyone around to update the firmware stubs from 1.1.3 to 1.1.6 :-\

Software & Accessories / Re: i folded and bought CC :(
« on: December 16, 2014, 06:00:09 AM »
For me, it was a no-brainer as I'm simply amortizing the "ownership" (rentalship) over a small monthly amount.

We'll see about how small this amount will be in the future once the near-monopoly market leader has phased out all "owned" software and is free to adjust rental fees at any time.

Of course, I can leave at anytime and select a different product, just as I have done by leaving Aperture for the Adobe ecosystem.  As a consumer, I can exercise that right at any time.

If there's something to switch to - Adobe has bought most major competitors and stopped producing their products sooner or later or incorporated them (like with Macromedia, Aldus, ...). As Aperture is no more, it's Adobe or DxO. And if they buy DxO, where do you want to go to? ACDSee?
