Lighting / Re: First external flash? Lots of beginner's questions!
« on: March 26, 2013, 07:20:57 PM »
My advice after been there, done that what you wrote: Really first get and read "Syl Arena: Speedliter's Handbook: Learning to Craft Light with Canon Speedlites", *then* decide what to buy. I regularly miss my bus stop because the book is so interesting and nicely written. It doesn't cover the 600rt, but you figure out the menu yourself, won't you :-p ?

Of course a dozen of 600rt are great (or just one for on-camera flash with a bracket) - but for multi-flash setups there are lots of other options that won't cost you €500 per flash, and with Canon's rf system you aren't able to trigger anything other than 600rt flashes (thanks, Canon) - so do read this book and take an informed decision.

Another one I have is this http://www.amazon.com/Canon-Speedlite-System-Digital-Field/dp/111811289X/ref=sr_1_1?ie=UTF8&qid=1364245252&sr=8-1&keywords=canon+speedlite+system it covers the 600 in very great detail including all custom and personal fuctions and when you would use each setting. But it isn't as good a read and doesn't cover as much hands on stuff as the Syl's Speedliters guide.
+1 - I've also got this one and it's boring, very few rather mediocre examples, it's basically a manual with some creative appendix. Skip it.


Is it worth it to get this book in addition to Syl's?

EOS Bodies / Re: 6D Autofocus not impressive

There still is no (zero, 0) full cross point at all @f2.8 (only @f4+), so precision with fast lenses esp. on moving objects should be very bad.
I think that's a little harsh. With a faster lens you do still have the centre cross point... it's just no more accurate than with a slower lens.

I admit my annoyance with the 6d af means that I might be a bit simplistic - but in fact many people seem to think that the 6d has a xxd-style center cross point (extra sensitive for f2.8 lenses) while with the 6d the opposite is true (non-cross overlay). Then think of the 1dx/5d3 double-cross points - doh. But of course for years photogs managed to shoot with the 5d2 center af just fine, and the 6d has improved the accuracy a bit (see lensrentals).

The imho real unforgivable point is Canon porting the 5d2 outer points 1:1 to the 6d when as far as I researched it you should better not use these, not only in dim light but because their precision and pattern detection is so bad and just behind the times. That won't hinder me from buying a 6d, but just saying...

So we'll see what this thing can do...

Please tell us your experiences, I'd be interested to hear from a pro if the 6d is able to do a wedding (I expect it does, after all the 5d2 was able to and the 6d center af is more precise and should be faster at lower light).

If you read my original post, I rented the 6D to try it out. I did not buy it.  I was seeking other opinions because many have said the 6D's AF was in the same ballpark of the 5D m III.

Maybe bad communication? The 6d af is 99% the same as the older 5d2 (2!), except that Canon added two non-cross points and made the center point more light sensitive. There still is no (zero, 0) full cross point at all @f2.8 (only @f4+), so precision with fast lenses esp. on moving objects should be very bad.

The 6d is designed for low light shooting of nearly static scenes, for everything else the keeper rate will be very low and less than the 60d or 650d/700d.

However, for action and moving objects, forget it, it's terrible. I took pictures of butterflies last week and my hit rate of butterflies in flight is abysmal, 10-15% at most

This is the worst-case scenario, same with my 60d, for these shots you have to get a 1d4 or 5d3/1dx.

How does the 6D compare to the 5DmkII?  they are about the same price.  Could someone who has used both give us their thoughts.  thanks

The advantages of the 6d over the 5d2 are (regressions: build quality, x-sync- shutter speed, joystick):

  • higher iso capability
  • less banding
  • higher dynamic range
  • center-point af up to -3lv
  • silent shutter
  • faster fps
  • longer battery life
  • shorter release time
  • better metering & auto-wb
  • hi-res lcd
  • small & light but good grip
  • top wheel lock
  • gps built-in
  • wifi built-in
  • newer firmware:
    • full support for rt flashes,
    • in-camera multishot/hdr
    • in-camera ca correction
    • 7x bracketing
    • dual afma for zooms
    • servo af customization
    • flexible min/max auto-iso
    • min shutter speed setting
    • orientation-linked af point

not bad guys... 19 pages and going strong on 1 or 2 features missed on an entry level rebel... wow... slow news week I take it.

Imho this thread reflects a recently wider spread dissatisfaction with certain Canon product decision, i.e. the "value" as in new/overall features  vs. price.

The Rebel is just a welcome issue for discussion, and I see it in conjunction with the 6d release (want an af assist beam (Nikon d600 has it built-in)? Get a €500 flash! Want to get the flash off the hotshoe? Get a €300 controller! Still want af assist? Get a second flash for €500 instead...).

Personally, I can't wait until FF trickles down to the Rebel. Isn't that the inevitable way things are going?

Certainly not - ff sensors will *always* be more expensive, but Rebels will *always* be the most cost effective cameras. Plus all the ef-s lenses only work with aps-c sensors because ff have a larger mirror, so unless Canon goes mirrorless ff won't "trickle down" but aps-c sensors will become better nearly obsoleting ff unless for high mp sensors.

Plus ff has some decisive disadvantages for the average shooter:

* smaller depth of field (hard to handle, or the larger dof/iso compensates part of the noise advantage),

* shorter reach (or *much* more expensive tele lenses) & more expensive wide angle lenses (easier to construct if nearer to the sensor on aps.c). Even standard ef lenses need to illuminate a larger sensor = more expensive...

will anybody actually believe that it is a NEW sensor if it does have 18mp?

No way - Canon will make it 19mp to keep it above the old 18mp sensors, but below the 20mp 6d :-> ... or they'll go for 25mp just for the sake of having more than Nikon's aps-c.

Software & Accessories / Re: DxO Optics Pro
« on: March 25, 2013, 01:16:55 PM »
I'm with Paul on this.  DxO's lens corrections and RAW conversion are excellent, IMO better than LR (slightly) and DPP in terms of output.

LR4 has added better lens correction over LR3, but DxO should be much better if you have a lens with complex distortion because they calibrate individual camera/sensor-lens combinations at different focal lengths. Problem is that it outputs demosaiced files, so instead of a 20mb dng I get a 100mb tif (or linear dng) breaking the raw workflow in LR.

Unless I really need it, I see no reason to even try DxO because I'm very happy with LR's workflow, cataloging and developing (ACR) + LR has many, many good plugins that add what's missing from the core program.

It really depends what "the same" is, because the good ol' 18mp sensor has come a long way from the 7d (haunted by banding) to the newer Rebels with af helper pixels for lv focusing.

If they find a way to squeeze the last performance out of the tech like on the 6d (better noise patter = easier to nr, zero banding, some more dynamic range) *and* the 70d has great features *and* a very reasonable price the 70d will still be a great camera for shooting in good light. But knowing Canon that won't happen, it's either a lukewarm update *or* much more expensive than the competition d7100.

Sure, the best of the best cameras will always be expensive, but I see no reason why a camera with 5DIII specs cant cost 1000 bucks in 5-10 years.

It certainly will, well, actually in 10y nobody will want to use the 5d3 as a doorstopper (and all other current dlsrs).

As for "expensive" it really is about what you pay for - yes, but only for bleeding edge hardware that is really expensive to produce because new facilities and r&d want to be paid, too. A large "premium" and "early adopter's" fee will probably also stay as long as we have capitalism (predictions are pretty good atm).

But as for software - the xxxd or maybe xxd line would be a perfect place to implement new features, but Canon only targets amateurs but not innovators, they very seldom update their fw after release. If they would hire the main Magic Lantern dev they'd have a stellar fw in a year's time that blows every other dslr out of the water - but they don't want to because they want to sell their top gear. And top gear is conservative by default, because as a pro you want 110% tried and stable equipment.

I think most of the DSLR innovation is now done.

Are you applying for a job as a Canon exec :-> ? ...

There's no end of features and ideas, for software just look at everything Magic Lantern has to offer (and the things they cannot do due to Canon fw constraints). How about an switchable ovf/evf with all the information it could offer (focus peaking for mf in the vf)? How about really smart af tracking across the whole frame ("Please track the player with the number 8", "Please always automatically focus the eyes")? How about 1/500 x-sync like on the original 1d?

roblem is, Canon is driven by product differentiation, max. profit (lowest cost & highest prices) and they are so conservative they probably don't think about real innovations, even not with a cpu as fast as their digic5 (or 6).

We need a 7D mark II with a cf card slot, a 5D Mark IV or higher with a cf card slot and a lot of lens replacements or new lenses.

What's so important about cf cards (or was that irony)? For my money, I want dual sd cards - smaller and also very fast.

This is not far from the truth.  In October 2011, Canon announced that the 50 millionth EOS cameras and 70 millionth EF lens was produced.  1.4 lenses to each body.

It's be really interesting if the ef-s lenses are included - but even if not this proves Canon marketing's efficiency, they manage to make people buy new camera bodies all the time - just like Intel/AMD convince users to change their mainboard/memory alongside their cpu but at the same time market them as "changeable".

Most people who get Rebels leave the stock lens on - or at best, get a 50mm 1.8...

How would you know? Just because the people in this forum are so well-off that they don't use Rebels with L glass? If I'd had to decide, I'd use 550d+70-300L rather than 60d/7d+70-300 non-L.

I heard the 5D Mark IV is just around the corner. The question is, whether to buy that or wait for the Mark V which will be even better.

Hey, I usually write this :-> ... but actually I really don't expect the 5d4 to be as late as the 5d3, the af is great (with good/expensive lenses, that is) ... but once (and IF) Canon updates their sensor tech imho the profitable 5d line will be the second to get it ... along with an internal rt flash controller, I hope.

Canon couldn't be thinking that the same old 18MP sensor will be just fine in the 70D and 7D mkII because of Digic6 ...  could they?    ???

You can improve jpeg noise reduction with a faster cpu and better algorithm, and you can lower banding with better readouts. The 70d might also get a better noise pattern like 5d2->5d3. And you probably can bump dynamic range a bit with the same sensor tech (see minor dr increase 5d3->6d) - but that's about it.

But Canon has a whole fleet of marketing people, and the less real innovations there are the more they matter and have to perform their magic - to the point of satire as these press releases prove.

So, unless you actually work at Canon, and was present at the meeting where the QA responsible took the decision to take the risk of never testing AFMA in a new camera body (and can prove that to us), I would not claim that I know how much it costs to add.

Ok, then let's say it's "next to zero cost" - I know features need testing and servicing, and that's why the Canon fw never will have the features of Magic Lantern. But afma is practically self-servicing: The user has to figure out the values, it's simpy added or subtracted from/to the transmitted af value, and you can reset it at any time.

Imho there is really no excuse for removing it, deeply hidden inside Fn it doesn't confuse anyone, it's only due to marketing as the removal 50d->60d proves.
