EOS Bodies / Re: 6D is amazing... Review UPDATED (practical usage)
« on: January 19, 2013, 11:13:22 PM »
The 6D should be compared cameras in the same range, not something higher..


If it's about price range, then the Canon competition is the 5d2, which is indeed the real successor to the 5d2 - for the some of the advantages of the http://www.canonrumors.com/forum/index.php?topic=11309.45

As for the real competition it'd be the Nikon d600, but we wouldn't want to compare that to the 6d w/o becoming suicidal :-p

But imho a comparison to the 5d3 is still interesting because it for example what current Canon firmware can offer and what has been cut from the 6d for no reason at all other than marketing / product differentiation, also for example the double-button layout of the 5d2 vs. the one function per button of 60d/6d.

So it's a good thing the outer points are not cross type because it's very hard to move th points using the thumb wheel thing...


Um, you're mixing that up - the outer points not being cross-type is about their precision, not about the physical method to select them. However imho for 9-11 af points a joystick is not necessary and it can also be done with a multicontroller.

EOS Bodies / Re: 6D's Wifi Drain on Battery (?)
« on: January 19, 2013, 11:01:17 PM »
The direction the device is pointing usually comes from sensing the direction of the earth's magnetic field and gives you a direction based on magnetic north.

I know, but since Canon's external gps unit contains an electronic compass I don't think it would have been impossible to also put it into the 6d camera - they managed to squeeze in gps and wifi after all... just the location information simply is underwhelming to me since imho an external logger is better for this.

Anyway, the camera failed to reduce the shutter to the camera's max sync speed (1/180) like you expect it to do.  As a result, the flash was clearly out of sync with the shutter. 

I take it you didn't enable hss?

Also, the metadata says "flash did not fire".  But obviously it did fire.

Might really be like a broken camera shutter-sync or firmware problem, maybe Canon didn't test all combinations that extensively if they are very desperate to release the gear to counter the competition (In Germany this is called a "banana product", ripens when with the customer).

Maybe you should post this on the official US Canon forum, there are Canon mods around that might give you some mode inside advice, esp. if the problem is reproducible. When in doubt replace the camera body if it's easily done and still possible.

I'd never measure myself against anybody's photos and would never ever challenge someone on taking photos.

Me neither, and the reason I'm never posting any "good" shots in discussion threads is that imho if someone has taken a couple of good pictures it doesn't make his/her reasoning any better or his/her opinion more valid, it just muddies the water. A good reason to post shots is to demonstrate problems or show the effect of some lens/lighting/... gear though.

The horizontal and vertical only AF points really only matter to things such as architecture, or where there are clearly defined lines.

I don't think so, it also matters on low-contrast surfaces - and often non-architectural scenes also have clearly defined lines, I know because I've shot for a long time with the non-crosstype sensors in the analog days.

GPS is super useful when going bushwalking, exploring with the family, or on an epic overseas journey.

... but a dedicated tracker uses much less battery esp. at faster update intervals than 5min, is most probably more precise and keeps on logging in your breast pocket even if the camera is safely buried in the case.

Wifi is super useful!

Wifi is useful for remote control as you wrote as well for shooting shy animals, but for picture viewing I never found it too inconvenient to put the sd card into my computer :-p

And! For all the above features, you save a wad of cash! Yay!

There's a famous saying of the former mayor of my hometown Berlin (Germany, that is): "You cannot save by not spending money you don't have" (rough translation).

The 6d is a ~2000€ camera body, I'd not expect some nice features from it but top performance - and here Canon unfortunately disappoints. Which won't hinder me from buying one if the price drops further, but I'm not going to sugarcoat it.

85L at 7.1. What a waste!!!

I never understood why portrait and extremely shallow dof seem to be synonymous for some - it's certainly nice to have the *option* for subject isolation and extreme background blur esp. if the bg is crappy, but if either the eye *or* the nose is in focus it's not necessarily the most pleasing look to me and probably non-photogs that don't get high when looking at a super-creamy bokeh (if they know the word) :-o

EOS Bodies - For Stills / Re: ISO 50
« on: January 19, 2013, 08:05:10 PM »
Thanks for the further explanation, I have to admit I didn't think this far :-o

Btw I always try to get around using hdr for focus stacking because using more than 100 shutter cycles for one resulting pictures is really something I only like to do if I know the shot will be stellar.

If you're going to the trouble of focus stacking...well, first, with macro work, there's often all sorts of specular highlights
Agreed, but there are also some low contrast scenes esp. in evening hours, I've shot enough stacks to be able to tell by now.

I don't know if ACR / Lightroom does that, but most tools based off DCRAW do. I'd especially recommend Raw Photo Processor

I'm afraid I'm running good ol' Windows so that tool would be only available in a MacOSX vm and I doubt it'd be worth the hassle, esp. since I'd end up having a demosaiced 100mb tif instead of a 20mb raw dng.

But I'm hopeful that in LR's raw processing adjusting the exposure doesn't collide with tone curves either applied manually or via picture styles.

If your tool of choice doesn't do exposure adjustments in linear raw space, then you're best off nailing exposure in camera, and ISO 50 therefore becomes (in that situation) a better bet than ETTR.

At least with the 60d I'm usually doing ettr and highlight recovery in Lightroom to get more shadow resolution. Since I haven't got a 6d with iso50 (yet) I'm unable to do a test the difference, but if I understand you correctly you're saying that if the postprocessing software is capable of operating in raw space iso50 should be equal to ettr @iso100?

EOS Bodies / Re: 5D3 vs 6D AF in low light
« on: January 19, 2013, 07:45:58 PM »
The definition of "low light" is critical to these conversations

Furthermore "achieving focus" needs definition, because in problematic lighting conditions the camera will take more time to focus - I hope the detailed dpreview.com 6d review will tell us at last if the -3lv rated 6d is getting a focus lock faster @-2lv than the 5d3 which is maxed out in this level.

so regarding of the subject (motive with no high lights = motive with a small DR) you can overexpose and get a benefit of the over exposure in the shadows

That's great information, thanks! I'll certainly use that once I've got a 6d and am doing tripod macro focus stacks with low dr objects.

Canon General / Re: After CES Whats Next for Canon?
« on: January 19, 2013, 06:12:43 PM »
14-24. Just curious about the pricetag ;-) Anyway, the 16-35 "will do". Planning on it for maybe later this year.

Personally, because of the expected €2500+ pricetag of the 14-24L I just bought a 17-40L which is as good as a 16-35L for my macro/landscape requirements and as an occasional ultrawide when a 24-70 would be too long.

I for one hope that the 450EX-RT (or whatever the 430EX II successor will get called) gets announced. That would be really nice!

... it would be even nicer if the 450rt (or whatever the number) wouldn't be €400+ but as I understand Canon's early adopter's premium policy it'll probably closer to the 600rt price than the 430ex2 ... and I'd like to see some rt tiggers for legacy speedlites and studio flashes please.

Pricewatch Deals / Re: Canon 6D - Meike grip on ebay for under $40
« on: January 19, 2013, 05:38:18 PM »
Still waiting.. 21 days and nothing...  :-\

Well, on ebay you often can see how the delivery times to be expected from China, to the US it seems to be a bit faster, but personally whenever I order to Germany I'm pleasantly surprised if it takes less then a month.

Just got mine today.  Attaches very well to the body.  There's no movement once it's locked down.

So you're convinced it won't loose contact once it's bent in an awkward position as described above? If it's really that sturdy then there really doesn't seem to be any reason to get the original Canon grip and I'd order mine from Asia so it arrives before I buy my 6d...

well there are a benefit with Canon sensors= less noise in the shadows=richer exposed but you lose 1stop DR


Interesting, though for the 6d at least dpreview cannot see any advantage except for skipping a nd filter: http://www.dpreview.com/previews/canon-eos-6d/7

The EOS 6D's lowest standard ISO is 100 but it can offer ISO 50 as an extended mode. Essentially this is doing the opposite of Highlight Tone priority mode - it's increasing the exposure by a stop, then using a different tone curve to pull the image brightness down to compensate. However, whereas HTP mode attempts to protect the image from highlight clipping, switching to ISO 50 makes it far more likely.

Because it's all-but impossible to recover over-exposed highlights, we'd recommend not using the camera's ISO 50 unless you have a specific reason - in everyday shooting you'd generally be better off using a neutral density filter if you need the longer shutter speeds. That's not to say that it's useless though; if you're shooting under controlled lighting and can be confident of retaining highlights, it should give the best quality.

This doorknob is important to me

Nice doorknob :-) and interesting story, actually I have some shots like this myself - it's just my point that you don't need a 63 point af system to take it or an expensive L prime for this resolution (a 50/1.8 would do).

I think we have plumbed the bottom of the Ken Rockwell topic.... perhaps we can stop now? :)

All KR topics end this way, but it's like like a train wreck, hard to look away :-p

If you're talking accurate camera-shot line-ups- GPS ain't gonna get you there without survey-grade enhancement.

That's correct, 10m (or less on signal reflection/occlusion) is about the precision of my gps unit and it's certainly not usable for professional surveys - but my point is that I can move 10m in 5 minutes, so the low battery drain in this scenario wouldn't be realistic for me since I'd have to set a faster update interval.

EOS Bodies / Re: New Rebel T4i vs 60d/7D
« on: January 19, 2013, 12:06:37 PM »
If you need ruggedness and 8fps, go for the 7D. If you need video AF and user-friendly interface, I recommend the T4i. Don't sell this camera short. It's a great piece of equipment.

I don't doubt that, but as personal advice to a friend I'd also recommend to have a look at the now very cheap 60D if you don't need the 650d video af/touchscreen or the 7d fps or af spread - the 60d has a good mix of usability and features.
