Olympus EM5 Mark II continuous AF performance.
Olympus EM5 Mark II continuous AF performance.
Has anyone done any testing on the actual performance of the OMD EM5 Mark II's continuous AF? I'm particularly interested in tracking pets, wildlife and children coming towards the camera.
I'd be interested to see any comparisons with the EM1.
I keep reading that the CD AF is improved, but haven't come across any specific examples or direct comparisons.
Thanks.

Re: Olympus EM5 Mark II continuous AF performance.
I'm curious also the only thing I came across was a video review that did a casual test of the CAF. The test starts at 6:50..He does say that the CAF is much improved over the EM5 MK1.

The E-M5 II should perform the same as the E-M5 when it comes to tracking, it's the same sensor with 3D tracking technology that gives it a marginal at best 1fps advantage over the E-M10 and PEN series cameras. Expect about 4.5 frames per second. The 3D tracking is accurate its just not fast. If you need fast AF tracking then you need the E-M1.
You're better off shooting using either the single point, or 9 point focusing system (press one of the arrow button, then info, then up arrow through the different focus modes) which will give you a less random focusing area than with the 80 odd other tracking points, and predicting where the action is at the end of the day though when it comes to tracking with the E-M5. You'll get better results.
Alternatively you can set your camera to manual focus and just use zone focusing which is quite easy once you set up where your plain of focus is going to be.

I don't agree. The reviewer actually tested the camera not just speculated. I'll go with his conclusion as to the improvement over the EM5. The sensor is only one part of the equation. The hardware and algorithms have a huge impact on AF performance. The AF performance of the Panasonic GH4 is very good and it doesn't use phase detection so I don't see why the EM5 MKII has to be limited.

That's some messed up logic
I wouldn't rate Darren Miles opinion as far as I could throw it. He's not a credible reviewer, not even in the slightest.
The GH4 uses a completely different sensor and focus system to the OM-D. Lets just start by saying the GH4 uses a Panasonic sensor and the only Olympus camera that uses a Panasonic sensor is the E-M1. The E-M5 II uses the same Sony sensor as in the OM-D E-M5 MKI. This is before you get into the other details, the firmware is completely different and all the electronics in the GH4 are completely different again to anything Olympus has ever released.
There are no tricks here, the OM-D E-M5 II has the same focusing system as the MKI version.

its 5fps as opposed to 4.5fps as rated by Olympus anyway, 3.5fps as rated by dpreview, there is nothing miraculous here.

I think Darren's reviews are excellent you are free to think what you want. I didn't say it was miraculous just that it's better than the model it's replacing.

I was surprised the contrubuting shooter on this DPR article had a few positive comments re: E-M5 II C-AF, compared not only to older bodies but even the E-M1. The video is ok, there's some extra info within the comments section IIRC.

Re: Olympus EM5 Mark II continuous AF performance.
Thanks for the replies. It seems that there aren't any direct comparisons btween the EM1 and EM5 II on CAF.
I realise that these comparisons are pretty hard to make at the best of times with the performance more than usually affected by the specific settings used and by their nature the situation can be pretty hard to replicate.
However, it looks like the fact that I'll mostly be using the 12-40mm (which uses CD AF) then the performances ought to be similar on the two cameras.

Contrary to what even some reviews state tho, the E-M1 does seem to employ PDAF + CDAF with m4/3 lenses under certain C-AF modes...

Interesting, hadn't seen that one, good link and breakdown of when and how PDAF is used. Despite some of the comments in the DPR article I liked (by the contributing photog himself), I can't imagine how the E-M5 II could top the E-M1 at C-AF while lacking the hybrid PDAF system... The fact that this isn't present was my biggest disappointment over the E-M5 II.

Then why do DPR say "The E-M5 II features the 81-point AF system that first appeared in the E-M1, allowing greater precision of focus point selection. There are more than 800 points on which the camera can focus if you use the rear touchscreen to specify a target. Furthermore the camera offers eye-focus if it detects a face in the scene, with the option to focus on the left, right or closest eye."?

You state that the mark 2 uses the same sensor as the mark 1. That is speculation. Olympus never said the sensor was the same. That sony sensor banded with the 20mm 1.7, the em5 mark 2 sensor does not. nobody really knows if it is the same outside of olympus employees.

If you are talking about C-AF not C-AF+Tracking, non-EM1 OMD cameras handle fairly well, starting from EM5, see the discussions:

If this is your reasoning, it makes no sense to me. Even if it is all CDAF, then still there can be a (huge) development in that area like Panny shows. From what I have heard, Oly's CDAF for tracking has become much better too...

He makes more sense than you do. CDAF is not sensorrelated (unless readout is too slow). It is an algorithm. Which is why Panny GX7 which uses the same sensor as GH4 is no good for tracking and GH4 is: the CDAF is much better.

Yes, EPL5 did fairly well too. GH4 does vaslty better, so does EM1. And I think EM5 MarkII also. Note that AFAIk EM1 does not use PDAF for its m43 lenses

Re: Olympus EM5 Mark II continuous AF performance.
My understanding is that the E-M1 does use a hybrid including PDAF for C-AF with mFT lenses. Just not for S-AF.
