6.1
2018-09-26
This is a wee update to bring support for iOS 12 and the various new iPhone X models.
Don't forget the key Version 6.0 updates:
*The interface gets an even cleaner, more spacious look. Simply slide the pointers on the distance scale to set distances (the old slider “thumbs” are now gone). Note that you do not need to keep your finger on a pointer as you slide it — you can move your finger to the side as you slide, all the better to see where the pointer is pointing.
*The pointers themselves can be set to display numerical readouts of distance. Or, if you prefer, you can have a readout of image blur for the objects at your selected distances. Or, if you would like fewer numbers on your display, just leave the pointers blank (that’s the default setting). Go to the settings screen to select your preference.

There are all manner of minor changes, including a more punchy colour scheme.

Support for iPhone X
5.1
2017-01-22
A more pleasant colour scheme, plus several small interface tweaks.
Of course, all the new features of the last major upgrade are still there:
• Numerical readouts for optimum focus distance and aperture have been added as a complement to 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 now 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.
• A marker can be placed on the blur spot diameter scale as a reminder of what you consider acceptable blur sizes.
• Distance units are changed directly on the main screen by tapping the m / ft button.
• An optional "distance snap" function has been added, to make the distance slider even easier to use.
• The Settings screen has been simplified (but presents more options).
• The option for displaying image sharpness in line pairs per mm (a concept more familiar to physicists than photographers) has been removed in favour of simply showing blur spot diameter (circle of confusion).
• The distance scale selection buttons now give a visual indication of their intended use.
• The wavelength selection button on the main screen gives a visual indication of the spectral range in which you are working (visible, IR or UV).
• Labels can be hidden, for a cleaner interface.
• Several info (help) buttons have been added.
And there are lots of other, smaller improvements.
Enjoy!

Completely rewritten, with a cleaner, more up-to-date look, and a more interactive feel.
The list of improvements is a long one:
• Numerical readouts for optimum focus distance and aperture have been added as a complement to 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 now 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.

Oh, and there's a new icon, and the file size is much smaller.
Enjoy!

4.1
2013-10-17
Numerous subtle (and sometimes not-so-subtle) aesthetic changes throughout the app for a more elegant look. Plus, a completely new “Settings” screen with no clutter (the “set once and forget” buttons being hidden from view unless needed), similar to the concept recently introduced on TrueDoF-Pro.
Bug fix - corrects a small error in the calculation of blur diameter in infrared photography.
4.0
2013-09-19
Added the facility to set wavelength, a feature for those shooting in the infrared or ultraviolet part of the spectrum.
Changed the action of the focal length scroll wheel:
- The scroll wheel now responds much faster when you tap the focal length “Up” and “Down” buttons.
- Scrolling now results in real-time updating of output (rather than having to wait till the wheel settles on your final choice of focal length).
- The wheel no longer free rotates after you stop pushing it.
Changes required for iOS 7 compatibility.
3.0.1
2013-09-03
Small changes to the User Guide.
3.0
2013-07-29
Longer sliders on the iPhone 5’s screen make for easier input.
A link to the new FocusStacker app - now, for the first time, you can use focus stacking in landscape and architectural photography with predictable, high quality results.
A link to an index page of feature articles.
Improvements to the user guide (’tis a remarkably easy app to use, but so flexible that a good user guide comes in handy… and it makes great bed-time reading).
Numerous small tweaks.
2.0
2012-06-08
* User-definable focal length presets, for lightning-fast focal length selection
* Distance scales switchable from the main screen
* An improved, easier to use, more elegant settings screen
* A new, expanded “Links” screen
* Instructions on using OptimumCS-Pro 2 with tilt-shift lenses
* A new look and numerous other improvements
All the other “pro” features, including blur diameter data display and the focus shift scale for use with view cameras, remain.

IMPORTANT NOTE: If updating, a "clean install" is recommended. This avoids potential issues caused by the substantial differences between OptimumCS-Pro 2 and the previous version. Simply delete your current version and then download the new one - it is still a free upgrade.
