Available in either a Canon EF or Nikon F mount, the Zeiss Otus 100mm f/1.4 lens is a manual focus optic which is aimed at portrait photographers. Although primarily designed for DSLR cameras, you could also use it with mirrorless cameras such as the Nikon Z 7 or the Canon EOS R via an adapter.

When it was launched, Zeiss claimed that the lens was one of the best in its class, capable of producing extremely sharp images and boasting outstanding build quality. Zeiss goes so far as to say that medium-format quality images are capable of being produced by the lens.

Like the vast majority of Zeiss lenses, the Otus 100mm f/1.4 is very expensive. At the time of writing, it costs around £3,499. When you compare it to other similar models, such as the Nikon 105mm f/1.4E ED AF-S lens, which is currently on sale for around £2,000 or the Sigma 105mm f/1.4 Art lens, which retails for around £1,500 (and are both autofocus lenses), it’s a costly proposition – but is it worth the extra outlay?
