Focus demands Resolution and Contrast

What determines sharpness and blurring in an image? Bertram Hönlinger, optics expert at ZEISS, talks about the performance of modern camera lenses and the limits of what is technically feasible.

Mr. Hönlinger, in photography the topic of “sharpness” is touched upon time and again. What exactly does it mean?

Bertram Hönlinger: One of my colleagues once put it like this: “Focus is an out-of-focus term.” By that he meant that there is no clear-cut definition of focus in photography. We see the concept much more on the subjective level.

But you are an optics expert. So I am sure you have a very specific image in your mind of what focus means.

Focus is closely related to depth of field. As soon as I focus on a point within a shot, say the eyes of a model when I am taking a portrait, a focal plane is created that ideally runs parallel to the camera’s sensor. One point on this focal plane will appear as a single point on the sensor – or almost will. It is a different story with the details in my motive points which lie either in front of or behind this focal plane: the rays of light reflected by them do not meet at a point in the camera sensor, but are in fact spread across an area around the target point.

This is known as the circle of confusion …

“The camera’s resolution capacity and the reproduction of micro contrasts makes all the difference when it comes to image definition.”

Wide-Angle Zooms

Play the angles and get the big picture with an ultra-wide zoom lens.
With zoom ranges starting at just 8mm for APS-C format lenses, and 11mm for full-frame, you can shoehorn vast areas into the image frame. They’re great for shooting sweeping landscapes or architecture, and arguably even more useful when shooting indoors, where space is limited – but that’s just the start of the fun.

A key attraction of ultra-wide lenses is that you can create images with extraordinary perspective effects. Get in close to the main subject in a scene and you can massively exaggerate its relative size, against a shrunken, receding background. Parallel lines appear to converge at alarming rates and shots generally have a proper wow factor. Another bonus is that short focal lengths equate to huge depths of feld. Unlike portraiture, where it’s often favourable to blur the background, wide-angle lenses enable you to keep very close subjects and the distant horizon simultaneously sharp.

Barrel distortion can also add to the creative effect, especially when using wide-angle zooms at or near their shortest focal length. That said, all of the lenses in this test group are ‘rectilinear’, aiming to keep distortions to a minimum. The alternative is a fsheye or ‘curvilinear’ lens, which give even greater viewing angles but with more barrel distortion.

Super-Telephoto Zooms: Canon vs Fujifilm vs Nikon vs Pentax vs Sigma vs Sony vs Tamron

Whether you’re shooting sports, wildlife or something else altogether, sometimes a standard telephoto zoom lens just can’t get you close enough to the action. A supertelephoto zoom lens will extend your reach signifcantly – and there are plenty to choose from.

A zoom range of around 100-400mm has long been a popular option to include in lens ranges (there are four included here), but some manufacturers have been pushing the envelope, super-sizing focal lengths to as much as 600mm.

Apart from the Fujiflm X-mount lens, all of the contenders in this group are fully compatible with both full-frame and cropsensor cameras. Naturally if you fit them to an APS-C format camera, you can extend your effective reach even further, with a 1.5x multiplication effect (1.6x for Canon cameras). Typical attractions include fast autofocus systems and optical image stabilisation, but there can be notable differences in features and performance. Let’s take a look at what’s on offer…
