Ratings and Reviews
Depth of field
When I first switched to digital. All my new lenses lacked any DOF markings. A great handicap and after finding this. I can know what to preset my F stop, for a given DOF. Take the guesswork of of you DOF get this and you won't regret it!
Great tool but Useless unusable sliders
This tool would be perfect if the distance to slider was actually accurate when used in feet & inches. It is virtually impossible to set the exact distance with the slider and therefore, for me unusable. This issue take a potential 5 star use all the time app to a 1 star wish I hadn't bothered rated app. Don't waste your time with this one unless they provide more control to allow EXACT setting of distance to slider in feet and inches. If nearly accurate is good enough for you though then go for it. Not for me thanks
Best of the free DoF tools
Of the free DoF tools, I've tried iDoF Calc, SimpleDoF and FieldTools. I found FieldTools to be the best - versatile, remembers settings (camera, lens, etc.). It does all I need and is free! The main enhancement I'd like to see is the ability to enter focal length, aperture and distance values by a selection wheel or keyboard instead of or as well as sliders - it's very difficult to be precise with sliders.
