How about a handheld shot indoors in a dark room at 300mm and f/5.6 (with the 70-300L), for .8 seconds at ISO 10,000?  Is that not low light?  If a 5D3 can autofocus in that amount of light, I'll go buy 10 of them tomorrow...

Those settings would result in close to EV +1. The AF working range of the 5D3 is between EV (-) 2 to (+) 18 so yeah ... it will autofocus.

Correct, because I wanted the image to look like the lights were on, even though they were off.  So I used positive exposure compensation.

I'm not sure I understand your post.

I can easily imagine a salesman in photo store babbling something like:

"Yes, this is a new Sigma 24-105! It's a great and mighty lens, just released! But... Look at this display for a second -- this is original Canon 24-105! See this red ring here? It's L-lens! Feel how small and light it is! IQ is just is as good. Do you like it? It's usual price is 3 hundreds more than Sigma. But today only for you, I can sell it for the same price as this 3rd party Sigma! And I even will add a filter and this Lowepro case for free!!! Because I see you are real 'pro' who need a lens like that!"

 ;D

Sure if the salesman spotted a noob contemplating this lens. 

People with commonsense will be better off buying the Canon 24-105 used on CL

What is your point?

Only that even in other parts of the world, the Canon lens is available for substantially lower than the MRSP when it is purchased as part of a kit.  So even in other parts of the world, the Canon lens is available for much less cash, as part of a kit, or used as the case may be.

I live in India and the Canon 24-105 can be purchased for local currency that is about equivalent to $ 900 - A used lens can be had for as less as $ 650. So what I was implying was that the Canon lens is available in other countries as a cheaper price too. Sigma will be priced above the Canon lens (when it is released here) - I doubt too many will buy it over the Canon lens.

I guess it is pretty much the same all over. but then, maybe in your country it may be different.

PS: Photography gear in India attracts customs duty of 30%, so @ $ 900 the lens is a bargain.

PPS: English is not my native language and I sometimes have difficulty getting my point across.  :(

Regarding profiles, I found Adobe's free DNG Profile Editor to be a nicer program than the X-Rite one.

As for the question why do we need them? Well if we think about it, the out of the can ones do not make any allowance for the lenses used, they can't possibly be neutral for all lenses, the only way you can normalise your output is if you normalise your input.
Hi, how would the workflow look with this? I am using LR4 today, will upgrade to LR5 soon. Will I have to convert my RAW-files to DNG ang applying this filter before importing to LR?
Thanks!

All the information you need, is available here -

Check out the documentation available on the DNG Profile Editor.

Yeah, it only undercuts the Canon because DxO still has the 24-105 costing 1250, which is far above its current street price.  It may be a slightly better than Canon's 24-105, but with the Canon version selling at 600-700, the Sigma isn't quite the bargain as when the Canon sold at 1250.

Canon's MSRP for the lens is $1149.

That is somewhat irrelevant since that is not what people are paying for it.  The question would be what is the actual street cost of the two lenses.
That is somewhat relevant since not the entire world is living in the countries where the street price is the mentioned above.

As a corollary, Sigma lenses aren't available in the entire world  ;)

Even in other countries, the Canon 24-150 as part of the kit will be available for roughly equal to or less than the Sigma.

BTW, from personal experience, Sigma's after sales support in other countries sucks big time!

EOS Bodies - For Stills / Re: The Unthinkable: Swapped out 5D3 for 6D
« on: December 18, 2013, 05:18:21 AM »
Consider this, you are shooting a subject at a distance of 5 feet with an 85mm lens at f/1.2.

To be fair, the f1.2 dof is a challenge for any existing Canon af system because even the 5d3/1dx af points aren't spread far enough so there is no need to recompose, and this thin dof beats any phase af precision... learning to manually focus on the lens or moving the camera is a good idea, at least with macro shots I know it beats trying to phase af.

I've owned the 85L for a grand 3 days now and so far, I've found it to work pretty accurately on the 5D3. I'd guess the focusing would be even better on the 1DX.

 It's a challenge on the 6D though and I'd like to use a tripod and live view for shooting with this lens.

I'll do some test shots with both bodies and post the results.

The 6D works fine with Focus-Recompose if you are shooting stopped down and you have sufficient DOF. When you want to use fast primes wide open, it turns into a serious enough problem.

Consider this, you are shooting a subject at a distance of 5 feet with an 85mm lens at f/1.2. The DOF is 0.54 inches. The same shot taken at f/4 will give you a DOF of 1.81 inches.

So basically you will get by with the slower lenses on a 6D using focus-recompose, shooting wide open won't be so forgiving and the shots will be rendered OOF.

BTW, phase detect AF happens with the lenses wide open so focus shift when shooting wide open is a non-issue really.

"My aplogies to come off the thread for a minute:

- How and/or where can I get that profile? I mean, can I find one made one already to use as a guidance?
is that to load to the camear or just to LR/PS?

Thanks"

No, not off the shelf. The best way is to get an X-Rite ColorChecker Passport, or any standard 24 patch card, and Adobes free DNG Profile Editor. Take a little time and make a good solid dual illuminant colour profile and apply that to your files on import to Lightroom and you should be happy.

It doesn't go in the camera, it is for Lightroom and PS to read.

What I really like about this site is that it allows to edit the user posts indefinitely and delete them if wanted. Just one idea: It would be nice to extend the time a bit until the "Last Edit:" marker appears.

The reason is that at least for me as a non-native speaker I often find myself editing the post somewhat because after reading it again after a 1-2 minutes or so I think "Hey, that doesn't sound right". Because I'm not editing the actual content I then sometimes delete the post and re-post it to prevent it marked as "edited" - I don't know if I'm the only one doing that. Yes, I admit I could carefully use the "Preview" option, but it usually only dawns on me after reading it in the whole context after "Post".

Funny you didn't edit this post  :P

I run into the same problem being another non-native English user here on CR. It seems silly that a post is edited within a few minutes of making it and others are bound to suspect what one's motives are for doing so. Nevertheless, I end up doing it quite often for almost exactly the same reasons as cited by you above.

A minimum time frame before the "Last Edit" appears with the post would be a nice idea!

Edited this post just for kicks ...

Cheers ... J.R.

<li>Teleconference insertion</li>


I like the idea of being able to insert a Teleconference. If we all get one, then we could confer over each shot.

+1  I teleconference when shooting with my 600 II, but I have to use my iPhone and BT headset for that - having a built in option means one less accessory to carry.   ;)

Yeah what an awesome feature...  And people say canon isn't innovating...  Take that Sony!  :D

Well all this talk about the 6D AF in extreme low light...  What the hell are you guys shooting that requires AF?
