Universal Lens Kit

No lens is perfect…

 

…but every one can be

Capture One Complete has developed the Universal Lens Calibrator to overcome many of the common problems inherent in all camera lenses.

Please note Capture One Pro software is required to use the Universal Lens Calibrator and is not included in the kit.

Inspired by Phase One’s own Lens Cast Calibration Tool (designed to remove colour casts and light fall-off when using technical camera lenses with medium format digital backs), Capture One Complete has taken the concept a stage further and developed the Universal Lens Calibrator to resolve these and other problems with today’s lenses for all formats, from 35mm DSLRs through to technical cameras.

In addition the Universal Lens Calibrator can also be used as a white balance reference card and a dust removal tool!

Capture One Complete’s Universal Lens Calibrator works in conjunction with Phase One’s Capture One Pro software 6,7,8,9,10 & 11. Please note that both products are required.

Why produce a Universal Lens Calibrator?

Every lens has built-in flaws that affect the final image quality. This can be true of any lens regardless of focal length. Whilst issues of chromatic aberration and vignetting are usually associated with wide-angle lenses, at Capture One Complete we have discovered that most, if not all, lenses suffer from problems to a greater or lesser degree. We have also discovered that in the majority of cases we are not even aware of the extent to which image quality is compromised until we see a corrected image after using the Universal Lens Calibrator.

Furthermore, the Universal Lens Calibrator , working in conjunction with Capture One Pro software, creates a unique correction for an individual lens used with an individual camera's sensor.

Here are some examples using Canon's 24-105mm f4L IS USM lens on a 5D Mk II body. This is arguably one of the most popular 35mm DSLR combinations, and the 24-105mm lens is considered to be a very capable performer. However, you can see from these plain grey images exactly where the lens problems are, and in the corrected files you can easily see how the Universal Lens Calibrator and Capture One Pro are able to fix all of these issues.

All the images were correctly white balanced. You can see the image files before any lens calibration is applied, and the same image after calibration. All images are shot at ISO 100 and f8.

With the lens set at the wide-angle 24mm setting, you can clearly see light fall-off at the corners in the uncorrected image. There is also a slight bias towards cyan at the right side, although that is difficult to see in these web images. Again, using the Universal Lens Calibrator and Capture One Pro removes that cast and fully neutralises the image.

With the lens set to 35mm there is still noticeable light fall-off towards the corners. With the lens at this zoom setting the colour shifts slightly from the neutral centre in all directions. Once again, using the Universal lens Calibrator and Capture One Pro solves all these issues.

You can see some real world examples from the Canon 24-105mm zoom lens, and the 17-40mm zoom, from photographer Paul Gill here.


Untreated RAW file with no ULC correction

Lens set to 50mm, no correction applied


RAW file after ULC correction

Lens set to 50mm, correction applied

At a 50mm zoom setting it is surprising that we still see some light fall-off and there are still some small fluctuations in colour towards the edges. Once again all is fixed after applying the lens corrections from the Universal Lens Calibrator.

You can see some real world examples from the Canon 16-35mm f2.8L USM zoom lens from photographer Steve Todd here.


Untreated RAW file with no ULC correction

Lens set to 70mm, no correction applied

Lens set to 70mm, correction applied

Even at 70mm there is still a clear difference in density from the centre to the corners. This is not caused by the manner in which the shot was taken - it is daylight lit on a cloudy day so the light is as even and flat as it possibly can be! Once again you can clearly see how the image is improved after correction.

Lens set to 105mm, no correction applied

With the zoom setting at the telephoto end it is clear that correcting the image using the Universal lens Calibrator and Capture One Pro improves the evenness of light and colour across the image.

These examples show how images taken with a Canon 24-105mm lens have inherent problems that remain with normal RAW conversion. Every photograph shot with this camera and lens and processed without any lens correction applied will exhibit these flaws. However, having created these reference files at each zoom setting at an aperture of f8, every image subsequently shot at f8 can be fixed instantly by simply applying the relevant correction before processing the RAW file.

In another example, photographer Stephen Ashton used the Universal Lens Calibrator with his 70-200mm f2.8 Nikkor lens. This is not a lens that we normally associate with any "lens issues", but the results are surprising nonetheless. You can read Stephen's full comments here.

Photographer John Robinson has also been using the Universal Lens Calibrator and has provided an in-depth report here.

Using the Universal Lens Calibrator in conjunction with Capture One Pro software, you are able to remove virtually all lens-related issues from all your images. Capture One Pro enables you to save your own Lens Presets that you can apply instantly to any selected images with a simple mouse-click.

Unlike off-the-shelf software fixes for lenses, the reference images that you create with the Universal Lens Calibrator are individually tailored to your own lens and camera sensor, ensuring a perfect correction every time. As no two lenses are the same, generic lens correction software packages deliver an “average” fix for a particular lens type. The Universal Lens Calibrator delivers an exact fix for your sensor with your own optics ensuring a better result.

How does it work?

The Universal Lens Calibrator includes everything you need to create reference images from your own lenses using Capture One Pro software (required). Capture One Pro software then uses these reference images to fix all your images quickly and efficiently.

What can the Universal Lens Calibrator fix?

The Universal Lens Calibrator, used in conjunction with Capture One Pro, can fix colour casts and light fall-off caused by the lens, and can even remove dust spots from your images caused by dust on the camera sensor! When you add the additional tools in Capture One Pro to remove chromatic aberration, purple fringing, and other lens artefacts, by using the two products together you have an extremely powerful set of tools to solve virtually every lens issue.

What is included in the Universal Lens Calibrator?

The Universal Lens Calibrator includes lens calibration boards in 100mm x 100mm and 150mm x 150mm sizes, to suit virtually all lenses including those with a large front element, such as fast telephoto lenses, and to fit most universal lens hood and filter holders.

As an introductory offer, worldwide delivery is included free of charge to any regular postal address. All orders are posted from UK so please allow sufficient time for the goods to arrive.

Please note Capture One Pro software is required to use the Universal Lens Calibrator and is not included in the kit.
