From Hasselblad CFi&CFE Manual:
The CFi and CFE lenses feature a list of improvements on the basic CF lenses that together produce an increase in image quality, reliability and convenience in operation. They include:
* new internal design and new anti-reflection materials reducing stray light and enhancing the image contrast
* improved design and a new main spring extending life expectancy and increasing precision
* PC-socket with positive lock
* redesigned focusing mechnism
* reinforced rear bayonet
* front bayonet in durable non-metallic material
* new external design for comfort and style
Filmcapture,
Excellent.
I will add a few items.
CFi the “i” signifies improved
1. Easier to read scales (numbers are larger)
2. The main spring is made of "Nivarox”
3. Improved grip controls on the focusing ring, shutter speed ring and on the FLE ring on the 40mm and 50mm lenses.
CFE The “E” signifies electronic. In addition to the improvements above, E lenses have 4 data bus contacts on the lens mount that allow the lens to communicate with the 200 series cameras metering system. CFE lens offer all the improvements found in the CFi lenses.
Occassionally you will come across CB lenses.
CB the B signifies basic. Some features have been removed from the lens.
1. The “F” function (leaf shutter lock up) has been removed.
2. Has a 1-year warranty instead of 3-year warranty.
3. Has one color of paint. All white vs. CFi, which has orange on the EV scale.
4. Reduced price.
