E-M1 Mk III - CAF + Tracking ?
1

Hi All,

Is the CAF + Tracking on the E-M1.3 much better than the E-M1.2? Along with other changes in the E-M1.3, that is a deciding feature for my possible upgrade. Latest E-M1.2 firmware upgrades improved the camera a lot, but what does the E-M1.3 offer that I do not have?

Or the E-M1X?

As far as I could tell the C-AF + Tr is identical between the E-M1ii and E-M1iii. The only improvement that we've seen in this area from Olympus are the AI Tracking modes in the E-M1X.

Using the Olympus 12-100mm F4 lens I don’t see any appreciable difference between the Mark II and the Mark III

Same with adapted Olympus 4/3 lenses.

I don’t find CAF+Tr mode to be very reliable with either camera. CAF works better for me.

I have tried the tracking on both the E-M1 II and III and found no appreciable advantage with the Mark III

I actually don’t use the tracking because I have found that using C-AF with all 121 focus points hot is super reliable, more so than using a smaller grid pattern with tracking.

This image is one from a multi shot burst, C-AF with all focal points, and the Mark III picked it pretty clean from the background, I think. This is what I have come to expect.

According to the reviews I saw:

-C-AF keeper rate increased with 10-15% for E-M1 MK III compared to MK II;

-the tracking is the same for all : E-M1 MK II, E-M1X, E-M1 MK III.

Although he tracking works in some cases, is not very reliable.

I recomand you to use always C-AF .

Re: E-M1 Mk III - CAF + Tracking ?

That is one area Olympus really should work on. I am quite (very?) disappointed with the tracking and subject detection of the em5.3 It is one thing to be able to move the lens focusing accurately when the subject moves (thanks to phase detection), but it is another to be able to follow and detect the subject in the frame.

For example, compared to the G9, yes, focusing feels more sure footed thanks to the absence of flutter in the evf, but the G9 follows the subject much better when it moves within the frame, certainly when it is a person or an animal, resulting in a higher hit rate most of the time.

And let's not even mention Sony's latest cameras, which are miles ahead in that regard.

Olympus focusing system reminds me that of a 2010 SLR. Quick and accurate, but not very "smart".

Maybe we will get AF-C+TR algorithm update until this Winter for the 1X at least? Since the E-M1X intro there has not been any sustantial AF-C update, right? Olympus by JIP has chance to fix it. They signed the deal with Oly.

Nice shot! Do you have situations however where using the whole matrix ends up in the camera missing entirely the first shot? I have had a lot of that with birds in the sky and I use a smaller grid in the centre

No...

Actually, I too had been using the 3x3 grid or the 5x5 grid and now find that by using the entire 121 point focusing points and letting the camera do the job, I have almost an instant lock on the bird. Maybe that says something about me lacking the ability to sometimes get a smaller grid over the bird for the first shot.

What matters is that you are getting the shot!

I think CAF Tracking is useful when subject moves straight towards camera.

Big difference between Mk II and Mk II for me.  I cannot comment on tracking however since I never use it.

I can  now use the 2.0X TC with the 300mm.  With the E-M1 Mk II, it was useless.  Focus was extremely soft in S-AF, a little better in C-AF but still soft and and unreliable.  With the Mk III, it works well in both S-AF and C-AF and it is quite usable.  I can even use the TC for BIF.

Also, I find that my photos are sharper with the E-M1 Mk III.

Big difference for me, worth every penny.

That is an interesting observation. I don't use tracking either om my MKII, but I've been wondering about C-AF improvement on the MKIII especially with regards to consistency and use with the converters for BIF. Thanks for sharing your experience with those.

two specific cases where I would say its better, one supported by very similar experiences by a friend who shoots the same subject / locations as me (I still have both bodies so its a pretty good comparison)

Shooting windsurf action off our local beaches using sequential low with CAF+Tr produces many images and one way of "junking" the numbers down was to reject all out of focus shots.

We have both complained that this option is now gone with the Mk3, we just don't seem to get a useful number of OOF images any more, so now have to examine each sequence more closely looking at content and match to objective (coaching, publicity shots, mates wiping out etc) which takes a lot more time

The other, specific to me, is shooting sequences of bees and butterflies in flight, using pro capture low this time. It seems to more consistently track the subject, butterflies in particular, as the fly between and in front of flowers and foliage

As I say, specific examples and I can't comment more generally but for these subjects its always the EM-1 mk3 I reach for. (the 2 is now used for flowers, portraits and the like, so good division of labour )

So much to learn, so little time left to do it!
