Re: Thinking of going back to Canon for birds/wildlife!

It seems to me that BIF is probably the most demanding use-case for AF there is. The truth is that mirrorless cameras in general still lag DSLRs. The very best mirrorless (think A6500, X-T2, E-M1ii) are now reaching levels of mid-tier DSLRs - which is great news. But... they still lag the best-in-class DSLRs in subject tracking and CAF.

Seriously, if BIF is an important thing for you, then go and get a Nikon D500 or a Canon 7Dii (Nikon probably the best). I love my Oly gear, but it's not (yet) the ideal tool for BIF.

Re: Thinking of going back to Canon for birds/wildlife!

I use a Canon 400/5.6 on my E-M1 (Metabones adapter) almost exclusively. C-AF you can forget, but S-AF is very accurate and quite fast.
Some samples here:
https://www.flickr.com/photos/421620...57659863679710
and here:
https://www.flickr.com/photos/421620...57673719653075

If I were to depend on fast C-AF, I would lean first toward a Nikon D500 + 200-500, or as a second choice, a 7DII+ 100-400 II. The 400 prime is sharper on the long end, but the zoom has some obvious BIG advantages.
That all said, I am waiting for the O-M1 II. For me, the advantages of the Oly-Canon setup outweigh the C-AF advantage of the DSL-Rs, and there seem to be real improvements in the OLY C-AF in the Mark II.

Re: Thinking of going back to Canon for birds/wildlife!

Just face up to the fact that there are some things MFT excels at and some it does not. Go for the 7d2 or better still an 80D plus 400/5.6L and you will wonder why you ever bothered with MFT for birding. Even my oldish Canon 60D plus 400/5.6L does the job with no frustration at all. It is a straight forward case of horses for courses. I have just one lens for my Canon body, everything else is done with the Oly M1 because I much prefer using it to the Canon.

Re: Thinking of going back to Canon for birds/wildlife!

After reading the responses here I feel I must refine my birding technique with this system before I jump ship.
Thanks for the replies.

Re: Thinking of going back to Canon for birds/wildlife!

In my experience, the E-M1 is OK if the background doesn't compete with the subject, like a bird against a clear sky. But if the background is detailed then there is going to be trouble. Acquiring focus in the first place is the real challenge and that takes skill.

Agree with Ian on that point! Practice is also very important.

Wouldn't that also apply to the much vaunted Canons?

Re: Thinking of going back to Canon for birds/wildlife!

As I understand it, the Canons and Nikons look for objects that are nearer first, and Olympus looks for further away. They may have changed that with the E-M1 Mark II. I remember one of the Oly people in Japan saying that the new camera looks for nearer objects first. I am no expert here, but it stands to reason.

Re: Thinking of going back to Canon for birds/wildlife!

Hi I read a review the other day on the em1 mk2 it compared the em1 mk 2 against the Nikon D3 which they reckoned to be the standard bench mark of this type of photography.
In a field test in all these modes, CAF in particular the EM 1mk2 had 60% - 70% Hit rate The D3 managed 70% - 80% hit rate, granted they said it was the pre production model, and that some improvements could be possible with a system update, either before it's hits the market or soon after.
Wish I could remember the review that I saw.
He did not that the continues frame rate was higher on the em1 mk2.
He noted if he reduced the frame rate to 6 per second he did get almost 100%.

When my M1 is pointed at a flying bird, it first goes as far away out of focus as it can and then returns back to look for focus, by which time the bird is no longer in the finder. By contrast the Canon seems to go from initial out of focus in the correct direction for focus. There is no frustration at all, it just works. What I fail to understand is why anyone would pay for instance 2000 or more for an Oly 300mm, when the same cash would buy a Canon 7d2 and a 400 f/5.6L (HDEW Cameras prices) and just get the job done. Life is too short to battle uphill all the time.

Re: Thinking of going back to Canon for birds/wildlife!

Well... here is one reason:
31337797225_b617a15555_b.jpg
Neighbors chimney just before dark, 559mm, hand held, (no monopod, tripod, window sill... nothing).
The Olympus IBIS has been a true life saver on MANY occasions! . With the Sigma 150-600, the IBIS is far superior to the Sigma OS.
It is true that in good light IS becomes less of an issue and if there is really good light, I prefer to turn it off all together. There have been many occasions though where the IBIS has been absolutely necessary fir BiF. I don't mind a little motion blur like in the wings, but the head and especially the eye should be clear. So that means that a 7D2 + a 100-400 II would be a better choice, albeit a tad pricier. A D7200 + 200-500 would fall in roughly that category.

Posting a very unsharp image of a static chimney pot is a proof of something, but if I expanded on that, I am sure that my post would be deleted.

Why? I seem to be missing something!

As I understand it, CD-AF will tend to focus on the majority of contrast content, apparently starting from infinity & if the subject in the foreground is the intended target but does not fill the majority of the AF area (box), then it will focus on the majority, which could well be the background. With PD-AF of DSLRs, I understand it will focus on nearest objects.

Also, as I understand it, the new E-M1 Mk II uses PD-AF & CD-AF with their Dual FAST AF system, as seen on Olympus Australia's website in the screen snip & should behave very much like a DSLR when focussing, only better (I hope), because of the accuracy of CD-AF.


EDIT: For more on the limitations of CD-AF with regard to the majority of contrast detail in the AF area, see my new thread here.

Thanks, Ross! That looks promising....

A hand held picture of our neighbors chimney just before dark through a dirty double glass window at 1/15 second with a focal length of 559mm is proof that the Olympus IBIS is a life saver, something you will not have on your 7D2-400/5.6 combo. Simple as that.
