Panasonic Leica 100-400 f/4-6.3: Making it all possible...

Recently, I was fortunate enough to take an adventure that was a life long dream. I packed my trusty F-Stop Kenti pack full of my Olympus micro four thirds (M4/3) gear, and after 15 hours in the air, landed in South Africa. After 3 days in the beautiful mother city of Africa, Cape Town - and believe me, Cape Town was not incredible in owns right - it was time for Safari!

And on Safari, one piece my my kit shined above all others...the Panasonic Leica 100-400 f/4-6.3. Now don't get me wrong, without the truly magical Olympus O-MD E-M1 ii, I would not have had the incredible speed and brilliant focus the E-M1 delivers at my fingertips. But without the Panasonic Leica 100-400, I would have missed incredible opportunities to capture the animals that surrounded me with such creativity.

In the past, I have shot with both super telephoto zooms and primes in multiple mounts. Past lenses with reach beyond 300mm have included:

  • Sigma 50-500mm f/4-6.3 EX DG HSM

  • Sigma 170-500mm F5-6.3 APO

  • Sigma 400mm f/5.6 APO Telemacro

Comparatively, the new 100-400 is in an entirely different league. Packing a 200-800mm equivalent lens in a 2.17 lb package, under 6.75" in length, one may wonder if this lens is too good to be true...

Well after several weeks in hand, I assure you it is not. In fact, it is quite the opposite as this lens not only has excellent optics, but the incredibly compact, weather sealed form factor leave it with little competition on the market today....especially at its price point. Coming in at $1800, the price tag is not modest, but it falls roughly in the middle of the pack when comparing to similar lenses in alternative mounts:

  • Pentax HD PENTAX D FA 150-450mm f/4.5-5.6 DC AW ($2500)

  • Fujifilm XF 100-400mm f/4.5-5.6 R LM OIS WR ($1900)

  • Sigma 150-600mm f/5-6.3 DG OS HSM Sports ($1800)

  • Panasonic Leica 100-400 f/4-6.3 ($1800)

  • Tamron SP 150-600mm f/5-6.3 Di VC USD G2 ($1300)

  • Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary ($1000) - not weather sealed

However, from a form factor standpoint this lens excels:

  • Panasonic Leica 100-400 f/4-6.3 (6.75") (2.17)

  • Fujifilm XF 100-400mm f/4.5-5.6 R LM OIS WR (8.29") (3.03 lbs)

  • Pentax HD PENTAX D FA 150-450mm f/4.5-5.6 DC AW (9.51") (4.41 lbs)

  • Tamron SP 150-600mm f/5-6.3 Di VC USD G2 (10.24") (4.42 lbs)

  • Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary (10.2") (4.3 lbs) - not weather sealed

  • Sigma 150-600mm f/5-6.3 DG OS HSM Sports (11.4") (6.3 lbs)

and when it comes to reach it performs quite well

  • Sigma 150-600mm f/5-6.3 DG OS HSM Sports (240mm - 960mm)

  • Tamron SP 150-600mm f/5-6.3 Di VC USD G2 (240mm - 960mm)

  • Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary (240mm - 960mm) - not weather sealed

  • Panasonic Leica 100-400 f/4-6.3 (200mm - 800mm)

  • Pentax HD PENTAX D FA 150-450mm f/4.5-5.6 DC AW (225mm - 675mm)

  • Fujifilm XF 100-400mm f/4.5-5.6 R LM OIS WR (152mm - 609mm)

Prior to departure for Africa, I spent several hours over a two month span getting to know not only this lens, but the O-MD E-M1ii as well, as I had owned both for a meager 2 1/2 months. Now admittedly I have been passionate about photography for many years, but to understand the way in which a new system works so as to be able to adapt to rapidly changing lighting or dynamic subjects, 2 1/2 months...10 hardly any time at all. Practice makes perfect...

So confident had I come to feel that the Panasonic Leica 100-400 was ready for prime time after a mere 10 weeks, that I rolled the dice and opted to take only one body when assembling my Safari Photography Kit. Typically, most would recommend taking two bodies for several reasons:

  1. Flexibility

  2. Versatility

  3. Speed

  4. Quality

  5. Failure

Simply put, the 100-400 offered flexibility and versatility second to none, while only (potentially) compromising in Speed and Quality to a unnoticeable degree compare to a prime lens. I was more than happy to trade the rapid focal length change offered by this high end telephoto zoom, for a two body, two lens solution.

Examining one photo below taken at 400mm, full size as compared to 100% crops from the center and the edge of the frame you can see that the lens holds up well throughout the frame:

While on Safari, I used the lens extensively throughout its entire range (see captions of images below). The majority of use was evenly split between 250-300mm and 350-400mm, with less use (but still a significant number) coming in between 100-200mm. As a zoom lens, the PanLeica 100-400 allowed for quickly changes to focal length and permitted capturing the same scene in multiple perspectives:

Shooting with full manual control, only minor adjustments in shutter speed or aperture were required when changing perspective on a particular scene. Alternatively, using a two lens solution would have required more drastic changes in camera settings in many instances, as the second body would be set for the previous conditions, and it would introduce a time delay when switching bodies. Switching lenses on one body was also kept to a minimum due to dusty conditions, but most of all due to not wanting to stop pointing the camera at the beautiful animals in front of the lens.

With the excellent zoom range, subjects of variable size and distances were also equally handled with ease.
