To all who are interested and didn't recognize it yet

Thanks - still no 6d unlike in the US, so lucky me I bought it for ~1500€ and the price has gone up since then :-> ... and it's funny to see that there are more months of the year *with* Cashback in Germany than without, so basically you have to be in a real hurry to buy these for the full price.

Btw. These cashbacks are less than the last, I got €100 on the 600rt, the 24-70L2 was €300 instead of €250 now...

... and I missed the chance to sell my 430ex2 via ebay in the short period w/o cashback :-\

Yes. The Hi ISO advantage disappears.

I wouldn't know about you guys with the big lenses, but I know this is true for macro - shooting near 1:1 with a ff has a so much thinner dof that a crop is at least equivalent in terms of required iso, plus the crop has got the longer working distance.

Edit: One more note: High iso on ff is *NOT* equivalent to low iso on crop because the higher iso always has less dynamic range - so the advantage not only disappears, but a disadvantage appears :-o

The market determines which is best, so.............

Hardly, given sufficient suppliy the market is the result of demand (= what the people buy), not what is best quality item for a price because there are a lot of other factors at play, even in a transparent market - which it usually isn't thanks to marketing :-o

For dslrs that would be existing equipment (learning loss and loss of selling and re-buying lenses), brand attachment and 3rd party enhancements, namely Magic Lantern. Add all these and Canon can very well sell an inferior product at a higher price while Nikon simply selling cheaper might not do them any good. There is also the "snob effect" which means a higher product produces more demand because it has to be better, right :-p

the 6D is a fine camera for the price, unfortunately at the price point it has a lot of unskilled amatuers have got their hands on it and tend to moan...' Oh but it doesn't have a built in flash'

Yeah, that's probably it - unskilled amateurs also naively tend to try to use the Canon menu af options (focus prio/accel/...) and orientation-linked af point and don't realize that these options make very little sense with the 6d's tracking or outer af point performance :-p

I think its primary weakness is that given its price, we will always compare it to D600 and D610 thus the expectations.  If its price is below D610/D600 however, I'd presume that no one will complain.

That's the point - it isn't, the 6d was more expensive for most of the time and now they cost about the same - the new Nikon d610 is priced a bit above the 6d (about €1700) while the discontinued d600 was and is cheaper (about €1500).

Shall I just buy her a 100mm L macro and be done with it?

Yes, if you can afford a 1d there is no question this is the lens to get...

How well does it work to do handheld flower macro with a non stabilised lens? Most of the shots will be at less than 1:1 magnification I expect.

... because of exactly this reason: the IS does make a big difference handheld at longer distances.

Lenses / Re: AFMA & distance?
« on: November 07, 2013, 01:29:29 PM »
25-50x the FL means you should be testing a 300mm lens at 7.5-15 m, not 2 m...

Thanks for the advice, I'll re-test my tele zoom at longer distance to make sure even though if it's zero afma right now, but maybe I'm in for a surprise. With the macro lens I'll re-think the distances since I'm dual-using it a lot and if it needs to be use 2 afma values for very short and very long distance since the dof is so thin @f2.8.

I also have to mention that this was probably the most competent and conclusive answer I could have hoped for :-)

Lenses / AFMA & distance?
« on: November 07, 2013, 01:10:25 PM »
Since my good ol' 60d doesn't have afma (thanks, Canon!) I'm new to this with my 6d and would like to ask some people with more afma experience for advice.

I just adjusted my lenses with Magic Lantern's dot_dune module which is basically a free in-camera version of FoCal and found that neither of my f4 zooms need afma (well, the 17-40L +1) at all at either end, at least not at the distance I could test them with in my room. I wonder...

1. My 100L seems to need more afma the longer the lens-subject distance gets. Did I do something wrong, is this normal behavior so I actually arbitrarily need to pick my favorite distance I'd like the lens to af? Do I need to test my 70-300L at longer distances than the 2m right now for accurate results?

2. I don't understand the scale of the afma values - does for example make the +5 of my 100L @1m a difference at the dof of f2.8 in real life? Or is this overcompensated by the camera's and my human's focusing variance anyway unless I shoot on tripod (and in this case would use focus peaking or contrast af)?

* ff has more leverage for postprocessing, this is what matters the most to me. If you try to raise one color channel on a gradient (say lessen or intensify blue on a partly cloudy sky) the crop shot will immediately fall apart while the bigger ff pixels allow for more postprocessing creativity or fixing.
This is true but an exaggeration. Crop images do not 'immediately fall apart.' You have to push to see the difference.

Not to be misunderstood: The "immediately" is concerning color channel operation like pushing or reducing blue sky or green grass - otherwise of course you can do a lot of pp with crop shots unless you're drowning in iso noise.

Quote
In reality, I find the ff has a 2-3 stop advantage over crop because with crop iso800 is the highest "safe" setting while with the 6d it's iso6400, and truth to be told I'd still prefer the latter if the dr is low.
The crop sensors are fine to about 3200

This has been discussed to death, so no need to re-open pandora's box :-p but to clarify: I find iso800 the max. setting which doesn't make that much of a difference @100% crop if properly exposed, otherwise it's up to the specific subject, print/display size and subjective feeling when nr+sharpening results in too much of a plastic look.

Well, you can keep on criticizing it but keep your expectations down since on the on-set 6D isn't even promised to be a prime body (or a decent body for that matter) for tracking actions.  There's a limitation on what the software can do for a hardware not built really for action or moving objects.  I'm with you though hoping that there's still hope but it is what it is.  Good luck finding your answers (work-around) though.  Deep inside, I wish you'll find it.  8)
One thing that could be improved through Magic Lantern is an option to select "af patterns", i.e. not only one or all af points but for example the 3 or 4 to one side which would make the decisive difference to tracking attempts - they're looking for a solution, but it Canon changed the fw 5d2->6d so the old method doesn't work anymore.

Also I'd like to point out again that "tracking with the 6d" is an optional extra for me, and I just want to get it working as far as it is capable of - otherwise I'm very happy with the 6d concerning its iq as I just commented here: http://www.canonrumors.com/forum/index.php?topic=17950.msg332856#msg332856

I know that you get a more shallow DOF and better high ISO performance with a full frame over a crop, but with good lenses on either is there really much of an IQ difference all other things being equal.

I recently added a 6d to my 60d, so I would say that next to intensive research I know both sides pretty well by now, so here's my general take: It is true that it is very hard to tell a unprocessed shot from a crop at low iso from a ff (at the same dof of course), and iso noise doesn't matter if you are shooting for key chain holder print size. *But* there are hidden aspects:

* ff has more leverage for postprocessing, this is what matters the most to me. If you try to raise one color channel on a gradient (say lessen or intensify blue on a partly cloudy sky) the crop shot will immediately fall apart while the bigger ff pixels allow for more postprocessing creativity or fixing. Also the ff has less problems on the red color channel on plain surfaces, a known issue with Canon sensors, try shooting a red mushroom if you don't know what I'm talking about.

* The recent ff models like 6d have virtually no banding (well, I've never seen it), quite unlike the 60d, not to speak of the older 7d - I don't know if this has gotten any better with the 70d. Banding after raising shadows is what kills your shot while you can reduce the film-like iso noise on the recent ff models a lot esp. with newer algorithms like DxO PRIME. In reality, I find the ff has a 2-3 stop advantage over crop because with crop iso800 is the highest "safe" setting while with the 6d it's iso6400, and truth to be told I'd still prefer the latter if the dr is low.

* Crop is equal to ff with good lenses, but you really have look out for them or use ef-s - my midrange 17-40L and 70-300L are much sharper wide open on ff, though the tele zoom has a radial bokeh on the outside that you can like (or not) that is cut away by crop.

* Noise: I'd like to advise not to underestimate the freedom this gives you, it's not just for very large prints nobody will really do but with crop you constantly have to trade shutter speed vs. iso noise as crop @iso800 is already problematic. Unless the dr is very high with ff you can just use a higher shutter which results in much more keepers, less headaches about tech but more thought about composition.

* If you use Magic Lantern: with ff you can boost your dynamic range to 14ev with a dual_iso 100/800 shot with virtually no drawback because noise doesn't matter at these settings - with crop iso800 already has noise so it's getting awkward. Also to get a thinner dof with crop you have to carry much more bulk, with ff my compact 70-300L @f4 is "thin enough" for me.

* Viewfinder: Not directly sensor-iq related and last, but not least - the more expensive crop cameras have an somewhat ok vf, but with ff you see more of what you're shooting due to the larger mirror which is a reason for ff on its own as in "iq for your eye".

I keep using my 60d because it's better for macro (deeper dof, larger working range) and tripod (swivel screen) as the 100L and 17-40L (@f8+) is sharp enough for crop - and of course for tele shots with 300mm * 1.6x crop factor which makes a decisive difference for wildlife. So I ended up where Canon wants you to end up - buying two cameras :-p

Well, that's how it is...  If there's any relief, I still got better pictures than my friend with 60D and 5D3.  I don't know what's your problem with it but if it can't serve your purpose then you have bought the wrong equipment.  You can't criticize something whose characteristics you know already before even buying it.

There's fundamental difference between you and me, and maybe also a difference between other CR members...

... of course I can criticize something I own and decided it's within my budget which will mean if has some flaws. I don't just stop pointing out the flaws just because I decided I can make do with it and work around the problems (with the help of constructive threads like this to find workarounds, not praise or bash the af system or each other for that matter).

Because if I wouldn't where would we end up - other people say you cannot criticize something you *don't* own because you don't have the proper experience. So if I cannot criticize something I own nor something I don't own, should apply for a job in Canon marketing :-> ?

I'd like to see Canon's apparently reverse-engineered system become the de facto standard so a camera can communicate intelligently with studio lights, meters, the whole shooting match.

I don't see any reason why Yongnuo wouldn't want to release triggers for rt older Speedlites and studio flashes, though it's duplicating their non-rt radio trigger/flash line, but if the demand is there...

What still puzzles me is Canon, they must have seen this coming, or someone just got fired for not properly encrypting their rt protocol. So I wouldn't exclude the possibility that something new is in the queue like the 430ex2 successor once the Yongnuo flash clones are actually on the market in sufficient quantities.

The other possibility might be that Canon indeed doesn't care which might be backed by the fact that the rt protocol is not very innovative other than the group mode which fixes the completely outdated/quirky ratio system - no second curtain remote, no remote zoom.

2143
Is it weather-sealed?

Meaning will they add some cent worth of rubber seals :-> ... probably yes, as Yongnuo doesn't use sealing as a marketing instrument.

2144
Thanks for that...in that case I will take 2 ;)

You just voiced my only fear about this - the specs are so good that the demand might make Yongnuo price this near to Canon's original even though both probably contain only $10 electronics parts... this will be the Yongnuo's equivalent of Tamron's 24-70VC which made them a respectable manufacturer and not just a 3rd party budget option.

2145
Only 1/2 stop increments........ A bit of a bummer!!

You seem to have misread (or the flashhavoc site got it wrong) - it's *1/3* stop only which is what I always use anyway.
