What's New in OptimumCS

6.1

September 26, 2018

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.

User reviews

Ever wondered why the mountains in your photos look out of focus at f22?

This app will help you with the calculations required to minimize the diffraction effect on your photographs. I use it for landscapes, but you can do the calculations starting at 0.3 meters. This is a must if you want to do the mentioned calculations fast while on location, especially if you already invested in a good camera an lens and want to get the best out of your system.

A must have for landscape photographers!

Where should I focus, what aperture value should I use? Using an arbitrary aperture value is not going to give you the sharpest image, do to defocus-blur and diffraction. Somebody has already figured this all out and has put it in very easy use app :)

Terrible interface

Great app but the new interface colours are terrible. Please put it back to the old colours.

Excellent!

Excellent work George! New interface is awesome! Please keep it up. I didn't like icon colours though.

Nice rewrite. Great UI

Great UI in the new version
