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.

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.

"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.

NWPhil, basic pointers to creating your own profiles can be found here

Hope this helps.

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?

Wait...  I have an idea.

Why don't you tell your wife about all this stuff you are buying?  She will put a stop to it!

WARNING : your wife may hit you over the head with one of your bigger lenses if you heed my advice :D

I guess I can't be of any help to you right now. I'm ordering a 300 2.8 II today ...

The only way to cure the "GAS" is go bigger and faster or STOP visit CR site ;D

I'm getting a battery grip for one of my 5D III, since I can't afford 1D X.

Congrats JR

It's a beautiful day in California, I'm going to test drive my 300mm f2.8 IS II at local zoo today.

No more visit local Sony Store until Jan 2014 ;D

Thanks Dylan and all the best with the new lens. Waiting for the pics.

Cheers...  J. R.

Not arguing, but thinking aloud that 300 should be enough with planning for a smaller package.

Sure, depending what and how you shoot. However, IMHO,  more buyers than not will buy the A7/A7R and end up shooting zero.  I suspect it will be bought by wealthy hobbyists, most of whom don't shoot much anyway.

I believe that if one a person is taking more than 300 photos on a vacation while walking around is being trigger happy.


Not really when on a vacation with kids.  I recently shot over 300 while my kids were having a great time at the beach.  Maybe if you are travelling alone one would shoot less.

In the net result probably I didn't have 300 great shots but I got a few very good ones,  some of which are framed and put in my living room. 

I don't care how many I shoot, so long as I get some shots that I want.  Landscapes...  Yes I plan for it and get them right in a few attempts.

I have both for the time being.  I got the 600mm first because I thought everything was shifting to full frame and was looking to replace an 800mm.  Like others have said, for birding, I think the 600mm II + 1.4x III is the best option.  If the birds are stationary, then the 600mm II + 2x III will also work nicely (super sharp). This is not a lens you want to travel that far with though, since it is big volume wise.   Also hiking around with it is cumbersome at least for me.  So that is something to consider.  I mainly use the 600mm II on a sturdy tripod and a full gimbal head. 

The 500mm is lighter on paper, but in my hands it does not feel that much lighter.  It is however, much smaller in volume.  So would be much easier to take on a plain or even to hike around with.  Still not sure I want to hike around with it much.  If you think you might be sticking with a crop sensor body (7D, 70D and maybe the next 1.6x body) then I might suggest you strongly consider the 500mm.  If not for the slight weight savings and size differences, then for the price difference.  The 500mm + 1.4x on a 7D is more than enough focal length for birding. 

I also have the 300mm f/2.8L IS II and would choose to use that, if I am going to be hiking around looking for subjects to photograph.  I'd use it without hesitation with the 2x III.  It is much lighter than either the 500mm and 600mm and it is super sharp even with the 2x III on it.

Don't know, if that helps you any.  You might even consider a nice used 800mm f/5.6L IS that can be had for around $8500 these days.

Best of luck with your decision.  If you decide on a 500mm II, I might have one for you :-).

Kind regards,
Jason S.

Thanks Jason, I would readily buy a used lens but given the fact that I'm in India,  it is not an option.  The superteles don't come up for resale all that many times. Buying from the US isn't such a great idea because imports attract a customs duty of 30%. A new super tell lens, in India, turns out to be the same if not cheaper.

Carrying the lens in the wild...  I'd take a couple of sherpas for that instead of breaking my back with either supertele.

I'll go for the 600 next.  The 300 should be here within a week.
