Olympus E-M1X vs full frame at 600mm

Introduction

Brief summary

  • the Olympus kit is FAR more affordable ($US5500 - almost a QUARTER of the price), far lighter and smaller (2.3kg vs around 9kg), does not require a tripod, has far more features (such as Pro-Capture mode, hand held 50mp HiRes mode), in-camera focus limiter settings, much closer focus, better weathersealing, is far more travel-friendly and much less conspicuous, gives far better hand held video stabilisation and an incredible 7.5EV Dual IS, has built-in GPS and sensors, lots of unique AF functionality to ignore backgrounds and foregrounds and the new AI tracking, AF works to much lower light levels and has a lovely articulating, swivel rear screen, and in-camera USB charging.
  • the dSLRs have the advantage of the optical viewfinder and thus much better battery life and much deeper buffer for longer burst modes at full burst and the best pro support systems.
  • the Sony has the best viewfinder, subject AF tracking and AF frame coverage but is severely lacking in lens choice, burst rate with mechanical shutter, extremely slow buffer clearance especially in extra large jpeg mode, is slowest to power on and get the shots, has the slowest shutter lag except when AF is already locked via half-press shutter release and, like the Olympus, RAW files in burst mode are only 12bit not 14bit.
  • BUT the compromise with the smaller sensor of the Micro Four Thirds Olympus means:
    • poorer image quality in low light when high ISO levels are needed to stop the action
    • less tolerance of poor exposure or cropping
    • less ability to achieve shallow depth of field (DOF) although this could be addressed through post-processing

At the end of the day, image quality is not as important as getting the shot, and the Olympus has everything one needs to get to the shoot location without being burdened, and without the need for a tripod allows far more creative shooting.

If you don't get the shot, then talking about pixel peeping image quality comparisons becomes totally irrelevant.

The Olympus gives you confidence you can take it almost anywhere and it is sufficiently responsive and versatile to handle most situations - as long as you don't mind a little more image noise.
