Tokina Opera 50mm f/1.4 FF Review - Performance

Tokina Opera 50mm f/1.4 FF Performance

Looking first at sharpness, the centre is very good from f/1.4 to f/2 and excellent from f/2.8 to f/11, remaining very good at f/16. The edges are very good throughout the range, from f/1.4 right through to f/16. A very commendable performance approaching that of the Zeiss Otus 55mm f/1.4.

The blue column represents readings from the centre of the picture frame at the various apertures and the green is from the edges.

The scale on the left side is an indication of actual image resolution as LW/PH and is described in detail above. The taller the column, the better the lens performance.

For this review, the lens was tested on a Nikon D810 using Imatest.

 

CA (Chromatic Aberration) is very well controlled, the centre especially so. CA will not be a problem, even in the most demanding situations.

How to read our CA charts

Chromatic aberration (CA) is the lens' inability to focus on the sensor or film all colours of visible light at the same point. Severe chromatic aberration gives a noticeable fringing or a halo effect around sharp edges within the picture. It can be cured in software.

Apochromatic lenses have special lens elements (aspheric, extra-low dispersion etc) to minimize the problem, hence they usually cost more.

For this review, the lens was tested on a Nikon D810 using Imatest.

 

Distortion is virtually zero. It measures at -0.05% barrel, but that is as close to rectilinear as we could hope for in any lens, even a macro lens.

Bokeh is gorgeous, ultra smooth and providing a lovely backdrop to portraits and other selective focus subjects.

Flare resistance is very impressive and in fact, no evidence of flare can be found.

Vignetting at f/1.4 is a modest -1.2 stops, reducing to around 0.75 stops for the whole aperture range. This could be corrected if desired, but often a slight degree of corner darkening can actually enhance a subject.

I would like to see a test with both this and a comparable Canon Model of your choice with this lens because I like this color rendering better than most after market Nikon lens and also on adapters with the new mounts from Nikon and Canon which are 55 and 54 mm if I remember correctly. Thanks for the review.
