How to Read an MTF Chart
|
MTF charts (short for Modulation Transfer Function) provide a graph analyzing a lens' ability to resolve sharp details in very fine sets of parallel lines, and a lens' contrast or ability to provide a sharp transfer between light and dark areas in sets of thicker parallel lines. Fine repeating line sets are created parallel to a diagonal line running from corner to corner of the 35mm frame, directly through the exact center of the image area. These are called sagittal lines, sometimes designated "S" on Canon's MTF charts.

Definition of Permissible Circle of Confusion
|
Permissible circle of confusion The range of sharpness of an image (picture) is determined by taking the resolving power of the human eye into consideration. A circle of confusion within the limit where the image is actually perceived as sharp is called the permissible circle of confusion (equal to or similar to the minimum circle of confusion).

TS-E90mm f/2.8 : How to set Exposure Compensation
|
When using a TS-E lens without tilting or shifting, all AR modes can be used as with normal lenses. Tilting or shifting, however, causes a metering error of up to one stop. since the slight exposure variation caused by this error depends on the tilt and/or shift amount, compensate the exposure as necessary.

How to set Exposure Compensation when using the TS-E17mm f/4L
|
The use of AE is not recommended when the lens is tilted or shifted as exposure errors may result. It is recommended that you use the exposure values when the tilt shift scale are set to the "0" position as a guide and then take the shot with as many exposure settings as possible
