35mm format verses 4 x 5 conversions
Today, the subject of lens conversions and equalities came up during Ms. Harkins' demo. According, to my research the 90mm 4 x 5 camera lens is equal to the 28mm lens of a 35mm camera format, in angle of views. So, that being said we now have to look at the 35mm you have. If it has a cropped sensor there is another conversion you must make. The chart in the upper left corner, has the conversion factor for cropped lens. In other words if you have a 1.6 cropped camera sensor you will need about an 17-18mm lens on your 35mm to test shoot a room at the same angle of view as the 4 x 5 camera 90 mm lens. Questions, ask away. You can get your own copy of the conversion chart by clicking here or simply click on the graphic in this article.DOFMaster for iPhone and iPod touch

Look what I found. All you "I" people might find this helpful. A DOF Calculator for the Iphone and Itouch. You can use the DOFMaster to calculate the depth of field in your photographs. You'll be able to select the lens and f/stop combination that provides the zone of sharpness you need. Use it to calculate the hyperfocal distance for landscape photography.
