Zeiss Otus 100mm f/1.4 APO-Sonnar Aperture Series: Backyard Trees (Fujifilm GFX100)

This series looks at the the Zeiss Otus 100mm f/1.4 APO-Sonnar at medium distance on the 100-megapixel Fujifilm GFX100, which has a 44 X 33mm medium format sensor.

A key and somewhat disappointing behavior seen here is forward focus shift (centering of the zone of focus moves substantially closer with stopping down). This behavior is discussed and shown on the Zeiss Otus 100mm f/1.4 Focus Shift page as well as in Painted Rock.

To obtain optimal results from the Zeiss Otus 100mm f/1.4 APO-Planar, it is essential to compensate for the focus shift in order to place the zone of sharpness ideally for the subject matter.

Zeiss Otus 100mm f/1.4 APO-Sonnar Aperture Series: Backyard Trees (Fujifilm GFX100)

Includes images up to 100 megapixels.

It was a joy not to have to deal with flaky autofocus and unstable lens focus as with the Fujifilm GF lenses, but I’ve satisfied myself as to the limits of the Otus with this series.

* As per longstanding policy, lens reviews always go into their native publication.
