  1. What is micro four thirds format? • It differs from your DSLR in 2 main ways • Mirrorless • Smaller sensor • What is the goal?

  2. Smaller, lighter 802 grams 1400 grams 1755 grams

  3. Entry level size comparison

  4. What is micro four thirds format? • It differs from your DSLR in 2 main ways • Mirrorless • Smaller sensor • What are the trade-offs?

  5. Mirrorless formats Not unique to m4/3 • All sensor sizes • Compact point and shoots have used it for years • Full frame in Sony Alpha 7 • APS-c in Nex, Fuji etc • Canon EOS M • 4/3 in Olympus and Panasonic • 1 inch in Nikon 1 and Sony RX 100

  6. Mirrorless vs SLR • Getting cheaper to manufacture • Less mechanical complexity • CDAF vs PDAF • Hybrid AF

  7. Life without a mirror • No mirror – no OVF (except “rangefinder”) • Composition on LCD – “Live View” works well for • Inconspicuous shooting, e.g. “street” • Ground level macro • Eye level shots of children • Video • Not so good for most everything else – esp long lenses, action • Electronic (eye level) viewfinder or EVF • Much improved past few yrs • Advantages and disadvantages in use – some prefer EVF

  8. EVF advantage examples • More information presented • Effects of EC visible in real time • Live “blinkies” or histogram • Larger! • OVF size relates to physical size of sensor and of pentaprism • EVF size independent of sensor size

  9. Viewfinder sizes

  10. Mirrorless summary • Advantages and disadvantages in use • Permits smaller body regardless of sensor size. • Necessary but not sufficient to produce significantly smaller system.

  11. What is micro four thirds format? • It differs from your DSLR in 2 main ways • Mirrorless • Smaller sensor • What are the trade-offs?

  12. We cannot change the physics of lens optics • We can only shrink the size of the lenses by shrinking the sensor size

  13. Sensor size - a trade-off • Bigger sensor equals better image quality • Better low light performance • Better DOF control • Smaller sensor allows smaller lenses • m4/3 lenses smaller than EF-S or Dx • Low light good enough? • DOF shallow enough? • Micro 4/3 is a compromise in sensor size not greatly different from crop sensor DSLR

  14. Sensor size comparison

  15. Sensor size comparison

  16. M 4/3 summary Hits a sweet spot for balancing image quality against portability for some photography. Travel Hiking Candids

  17. Hands on opportunity • Viewfinder • AF speed • Lens size and selection • Let me swap lenses • Feel free to snap away • Your SD card or mine • Auto ISO set to 1600 max on all cameras • Image stabilization is ON for all

  18. Special features of E-M1 • Incredible IBIS • Weatherproof • Touch screen shutter • MF magnify and focus peaking • Live bulb • Wi-Fi (“remote shutter release on steroids”) • In camera time lapse • HDR auto bracketing • 10 fps (50 frame buffer), 1/8000 • Hybrid AF (CDAF + PDAF)

He gives fairly non-technical reviews and is a very talented photographer. Ming Theinblog.mingthein.com • Ming is much more technically inclined but also produces great images. He compares many different formats.
