OptimumCS-Pro is the unique Optimum Camera Settings tool for imaging professionals — for photographers, cinematographers and videographers. As a professional, you spend a fortune on quality optics — OptimumCS-Pro helps you use that expensive gear to its full potential.
In all imaging work where you require the sharpest possible image across a depth range, OptimumCS-Pro is far superior to any depth of field calculator. You know that stopping down decreases image blur caused by defocus, but you also know that, on the other hand, it increases blur caused by diffraction. So you dont want to stop down too far. What, then, is the optimum aperture? And what is the optimum focus distance? OptimumCS-Pro is designed to answer precisely those questions.
And it alone gets the workflow right:
• Decide what are the nearest and furthest objects in your scene that need to be sharp.
• Set their distances in OptimumCS-Pro, and set the focal length of your lens.
• The app instantly displays the focus distance and aperture that minimise the combined effects of defocus blur and diffraction.
Yes, youll have the sharpest image across the desired depth that the laws of physics will allow (and therefore, in all cases, sharper than what youll get via traditional practice). But whats also great is that it couldnt be any easier, simpler and faster! OptimumCS-Pros instant results are perfect for creative professionals who don’t want their tools to get in the way of their work or their art.
In addition to the basic outputs, OptimumCS-Pro displays image sharpness information, so youll know if your shot will be sharp enough to meet your needs. Also included is data on shooting at other than optimal settings. Can’t shoot at the optimum aperture, because, for example, you need a faster shutter speed afforded by a wider aperture? You’ll know exactly what the effect of your decisions will be.
A few words on the "pro" version:
OptimumCS-Pro retains the elegant, uncluttered look of OptimumCS, adds expanded functionality and adds options to configure functionality to better meet your individual needs:
• User-definable focal length presets allow lightning-fast focal length selection.
• Numerical readouts for distances and aperture complement the analog scales.
• The optimum aperture snaps to your choice of the nearest 1/3 stop or the nearest 1/2 stop.
• The aperture scale shows 1/3 stop or 1/2 stop markers (user selectable).
• The aperture scale can be set to display apertures to f/22 or f/64.
• Several different distance scales, emphasising near or far distances, are available, as is one for use with Hansma’s focus shift method in large format photography.
• An optional "distance snap" function makes the distance slider even easier to use.
• The facility to set wavelength is available for those working in the infrared or ultraviolet part of the spectrum.
• The wavelength selection button gives a visual indication of the spectral range in which you are working (visible, IR or UV).
• A marker can be placed on the blur spot diameter scale as a reminder of what you consider acceptable blur sizes.

Latest reviews of OptimumCS-Pro app for iPhone and iPad
Doesnt work. Needs to be updated.
Excellent work George! New interface is awesome! Please keep it up. I didnt like icon colours though.
Great UI in the new version
Of all of the applications on my phone, this is by far the most useful. As a professional photographer of 17 years, I personally recommend this app to any budding professional.
No more calculations, charts, this app brings all the variables into play. Very easy to use, and I always have it with me. My Landscape photography has improved sense I started using this app. My old Ais lenses are getting a good working out.
