6D autofocus is a revolution
Feb 10, 2013

I was out in the garden taking photos , it was a dismal day, and the birds weren't cooperative. Still the low-light performace and especially autofocus was amazing. Luckily the squirrels were happy to pose:

Squirrel at ISO 5000, doesn't look very noisy to me.

ISO12800

The above photo isn't special, but the autofocus was. It didn't focus on the tree like my 40D invariably did, well to be honest the 40D wouldn't focus at all in this poor light. 

ISO 2500

Heres something I going to have to learn on FF, the depth of focus is so shallow that the squirrels face is out of focus.

This Great tit is a poor shot, but I included it to show what the amazing autofocus of the 6D can do

this is at ISO6400, with the 400/5.6 and 2X teleconverter, and it still did autofocus! Not even

the twigs in front of the bird stopped it. The 40D could never do that.



This ones a little better, it's the 400/5.6 and 1.4 TC , like I usually use, this combination focuses really fast with little dithering on the 6D. It's what I'll be using , but it's nice to know the 2X TC actually works too.

For me the autofocus capabilty of this camera is revolutionary, with the poor light we often have up here in the frozen North, the low light autofocus and image quality of the 6D is much more valuable than 63 focus points or 8fps, not that I wouldn't like that too, but I can't afford a 5D3, and the 7D isn't full frame. And the lighter weight of the 6D is going to be a boon on long hikes.

That squirrel looks like fight promoter Don King. Never seen ears like that on a squirrel in NJ...

Oh, and glad you're happy with the AF on the 6D. Believe it or not, I've been getting by with the AF on my 5DII for nearly 3 years now. Could be better of course, but for what I do, it works OK.

It was a guy standing beside me with a 5D (the original) at an airshow a couple of years ago, who got me interested in full frame.  He told me it focused fine , which got me thinking that theres more to a good camera than a perfect spec. Since then the full frame bug has been gnawing me. And like you say, which one isn't such a big deal.

Amazing!
In reply to Spad16, Feb 10, 2013

Eally cute pics, especially the squirrels. I would have dialled in underexposure a bit, according to my experience, the Canons tend to overexpose (although this can be very tricky with the bright snow).

Truly, if the camera focusses on the bird and not on the twigs, then this is really amazing. I had to switch AF off and  focus manually on my 40D for a shot like this, and due to lack of split prism, it is not very sharp:

This is typical for the Eurasian red squirrel (Sciurus vulgaris) which is the squirrel species found in continental Europe including Sweden, where the poster resides. It does not occur in North America; indeed, where the North American grey squirrel has been introduced in Europe (Britain, Northern Italy) it is in rapid decline - although it looks like a fight promoter:-), it is loosing "the fight" there...:-(

I am not saying that the 6D AF is bad, but those shots are not low light by any means. The camera does not care whether the ISO is 5000 or 100; only the intensity of the light (and the contrast) matter.

Nice shots!
In reply to Spad16, Feb 10, 2013

It's tough to get detailed shots in flat light like that, but you did a fantastic job.  The grain is nice and uniform in the higher ISO shots too.  The ISO 12800 shot shows how little DR is left but looks pretty good.

It's the same story here Christoph, more and more grey in our squirrels too.

Thanks Christoph, I was pretty amazed too, and it didn't just do it once , but seemed to ba able to do it all the time. Like you say the 40D just wouldn't do that, I'd always have to go over to manual focus in this kind of situation, and the teleconverters make things worse.

Your bird photo is typical of a lot of mine with the 40D, if a bird was in a bush or flying against a dark background, I wouldn't bother trying, looks like I can start trying again. To me this really is a revolution.

Is that a Crimson-breasted shrike?  East Africa? Nice one, a lot of my African birds are a lot worse!

Yes, thats true, but the second photo of the far off squirrel was really dark amongst the trees, thats why the camera went to ISO12800. The other squirrel photos I could have taken with the 40D, I have lots of better squirrel photos taken with the 40D. The ones that really impress me are the birds amongst the twigs, thats difficult, especially with a teleconverter slowing down the lens.

Thanks Allan, I noticed the same thing with your photos of Bearded tits, the 6D does a really good job of sorting out the subject from the background.

Quite worrying, so the grey squirrel is already in Sweden? I thought it is only present in the UK and Northern Italy so far...

Here in Darmstadt, Germany, I sometimes see red squirrels, no greys, fortunately so far...

However I had read that also red squirrels can have a greyish fur, the distinctive trait are the tufts on the ears...

Yes, it is, taken on a campsite in the Etosha National Park, Namibia. Quite close, I could not let it go without trying...

You'll find more of my Namibia pics in my gallery here.

I actually have to apologize, I took all those pics with my EOS 20D; at that time in 2007, I did not yet have my EOS 40D...

Thats good news, they all have tufted ears, so the grey is just a colour variation. Thanks for clarifying that.

Glad to hear that. For comparison see here a (not very good) shot of a "true" Grey Squirrel I took in Aberdeen, Scotland
