Let's be clear, the ONLY thing about E-M1 that matters is...

Completely right! For anything else my EM5 is sufficient. (Well, even my G1 focused fast enough for static objects.)

If it can do reliable 9+ fps tracking with 90-20/2.8, it competes with $6,700 1Dx (+ $13K 200-400/4 1.4 Extender to replace that $6,000 90-250).

If it can only do 4 fps or not reliable, it competes with $1,500 6D or even cheaper 70D/D7100 (and loses to the latter for the sports, and there are other cameras like E-M5 which are perfectly good if you don't need sports).

Even if it can reliably autofocus 9fps tracking with the 90-250, it would still compete to a €1,000 Nikon D7100 + €3,000 Sigma 120-300mm f2.8.


The D7100 does 7fps with 15mp in 4/3 sensor mode with the excellent D4 AF hardware, and in my own experience that works very well for sports.

Well, 7 fps cropped (which of course lowers resolution) or 6 fps full frame is still not 9 (or better yet 10). But it is a competition, and that is why $1,500 cost in uncompetitive unless E-M1 can significantly beat that.

From what I can read and see, the new Sigma 120-300 seems to be great value for money. Sharp optics, fast AF. (I have not yet tried one myself.)

So you don't know how fast it can actually focus?

IAC, it's not an easy market where the EM1 will have to compete. I sincerely hope it succeeds!

Be it more reasonably priced, say at $800 for a kit, it would have competed with much less tough crowd (NEX-6 etc), and could have sold well even without 10 fps tracking. At $1,500, it is no more than a niche the size of E-5 replacement market or less even if it focuses 4/3 lenses as fast as E-5.
