Default Freebies for Mac users

DOF and crop factor calculators - free widgets for Mac users .



For the DOF widget select APS and either feet or meters, then "done" from the back panel; for the Crop widget select Pentax for FF to APS-C and then "done" from the back panel; click "i" in the lower right corner of the front panel of each to get to the rear one.

For the DOF calculator - After entering the marked focal length being used (it calculates the crop factor for you), the aperture being used, and the lens-to subject distance ("focus") in the appropriate windows, you have to click on a blank area of the panel to activate the calculation. A graphic display shows both near and far focus - the only shortcoming is that, even though a mountain icon is used, there is no provision to enter "infinity", so you have to enter a figure for a long distance. A minor shortcoming for an otherwise very useful piece of software. Before using it, check the back panel to make sure it hasn't defaulted to Canon!

Ooooh - very nice! The only problem is that my dashboard is getting a bit crowded now.

Thanks for the links!
