That's because the intention of the thread is to find the best metering mode when in a hurry w/o even time for ae lock.

For anything that's just unpredictable or fast moving, but not totally surprising: Premetering, keep track of the various illumination levels in your environment.

but the simple fact is that Canon are not in the game at all in the consumer/prosumer market. He is just telling it like it is. A loyal Canon customer (and I used to be one of those) might not like it, but facts are facts.

Indirectly they are in - everything that doesn't use PL-mount is EF. That might have been serendipity back then, but until the a new de facto standard emerges they have a bridgehead thanks to being a common denominator in terms of adaptability.
That would on average give a speculative serious Canon a head start in lens stock and vertical integration.
How much that will do is another story.

About 90% of the time the external meter, either as incidence meter or as a less klutzy/strobe capable version of the multispot metering in the 1-series.

Lighting / Re: 72" umbrella... what to look for and what to avoid?
« on: December 03, 2014, 05:01:58 PM »
What is "a rib to go"? Can you please explain why you find umbrellas to be consumables? 

The spokes/ribs and the mechanics in general tend to be on the fragile side, much easier bent or broken then a softbox's rods but impossible to replace. A gust of wind is a common reason to get a new umbrella. (And the more resilient ones cost as much or even more then as your average softbox.)

As for which one to take - is the white one reflective or shoot-through? With a speedlight and its uneven illumination patterns a silvered umbrella can leave you with a uneven lighting. That makes a white one a safer bet, at least as a first shaper. (Filling in against sunlight is a different story, you'd need all the power you can get.)

EOS Bodies / Re: Sony to capture all the non-Canon sensor sales
« on: December 01, 2014, 03:58:18 PM »
There is no effing way I'll spend $2,400.00 on an 80D or $6,500.00 on a 5D4. YMMV.

Spend 1200 on the big cam instead of 1000 on a DSLR and 200 on a compact and it works out.
Bonus points: some lenses other then the kit one keep the revenue also up w/o increasing the camera prices.

Long term, that is not really a great situation for consumers

You always have the pure play foundries, those have the required skills, tools and experience with mixed signal and MEMS to create whatever you want at a structure size that makes even the most advanced DSC sensors feel ancient. Basically Samsung's current sensor is an example, even if the fab is owned by the same conglomerate.

That also keeps Nikon in a good position for negotiations, they have their own designs - Sony has to offer something competitive at a price delineated by the costs for a production run at any of those foundries.

Lenses / Re: I *HATE* UPS.

Are you ready to pay double the delivery price for better service and working conditions?
Lets take a somewhat different approach: default delivery to a logistics station strategically placed at a crossing of high volume public transport and easy car access.

Taking a slight detour after work or during conveniently scheduled activities would easily beat chasing down some random person in the neighborhood, driving to some backwater location or taking a day off to avoid the former troubles without certainty it will actually work.

At the current state of affairs not having your package delivered could even be offered as a premium service.
On the upside - the parcel services here do their best to keep brick and mortar stores alive.

and to my surprise, the measured dynamic range value of 7D Mk2 at 100 ISO is...12.7!!! Opening up other reviews on the site, looking only at DR values, i found out that, at 100 ISO:

The grouping around 12.7 +- a bit of randomness is a flashing neon sign pointing towards a systematic error.

You can see the wormy look here (and understand why he called it "wormy"): .

Once you understand that it refers to the D3/D300(still analog readout, pre on sensor ADC), it becomes obvious why it doesn't matter.

25
Who owns this lens? Speak from experience, not on paper regurgitation.
There is always the 3rd option, rent or borrow the lens. Added benefit - less incline to justify the decision, one way or the other.

26
Are many Nikon lenses designed to not correct well for CA?
It's most common in the superzoom-group, where a more complete correction would cause harder to fix problems due to other aberrations.

27
I'm not sure how the Sigma compares to the Nikon 24-120mm, then it's 15mm shorter & suffers from Sigma's reputation for having AF problems, so I wouldn't be surprised if the Sigma w/ F mount didn't sell well either.

The Nikkor was designed with the idea of correcting CA in software in mind. If one accepts this it's about on par with the Sigma or the Canon 24-105. The same situation as with the Canon - no great benefits, but also no first party service and you lose one lens that counts against the requirements for CPS/NPS.

Canon General / Re: Does Canon really deserve this?
« on: November 26, 2014, 10:36:00 PM »
As far as I know, Canon is the leading camera maker in the world, so they are doing something right.
That path of thinking can go horribly wrong - on the more graceful side GM's/big 3's market share hasn't recovered 40 years after relying on the trope, and how well Nokia handled similar disruptive changes in technology is in recent memory.

However, the dual pixel sensor technology is way ahead of everyone else, and gives Canon a big advantage in the video market and will serve them well when they do produce a viable mirrorless product.
What are the practical implications of DPAF in comparison to the PDAF the others use? First you trade an already dense grid of cross type sensor points for a slightly denser array of linear type points. Second you need separate readouts for AF and image generation(otherwise you could use AF while recording HD60p video or during LV sequences). The latter part in it's full severity is a consequence of Canons readout pipeline, but you'd still feel some impact in any technology that uses also image data. Now what do you gain? The ability to track subjects that are only a few pixels across without relying on contrast and motion vectors. Yet you want those two data set for subject identification anyway, but preferable at the highest possible update frequency.

Third Party Manufacturers / Re: Samsung NX-1 Review

Umm...how, exactly, do you shoot video with an OVF?

The same way it has been done for decades - use the shutter disc as mirror.

I really want to see some raw statistics generated for the NX1. I am very curious to know what it's SNR and DR are at higher ISO. I think this could be a phenomenal camera for astrophotography (with the one major caveat that there really isn't any control software out there that will work with it...most of it is for Canon, some of the newer stuff supports Nikon now, as Nikon is starting to take the lower end astrophotography world by storm.)

In that context a little detail - the NX1 relies much less then most other cameras on application specific hardware, it's  more in line with Samsungs other consumer electronics products, quite programmable and general purpose. Remember the part of the presentation where they talk about what you can do with lots of full res frames, and how the camera being designed to be extendable. Basically the interviewer asked about why only jump/ball detection, with the answer going along the lines of "just load an app, no big deal".
There shouldn't be a fundamental problem in doing ML-like stuff with that camera. :)
