The Canon EF 400mm f/2.8L IS III and EF 600mm f/4L IS III Super Telephoto lenses were announced September 5, 2018. An interview with the developers of the new generation lenses was published by Canon USA. The main improvements of the new lenses are weight reduction, improved IS performance and Image Quality improvement.
The Canon engineers tackled and overcame the following challenges :
- Retooled the lens from the ground up for an overall balanced weight
- Improved mobility and portability, with reduced weight
- A new optical system
- Optical, Mechanical, Electrical and Production difficulties
- Reduce the number of components
- Reduce weight and increase strength
- A new high-strength alloy for the lens barrel
- The latest gyro sensor is employed
- Best in class IS performance
- Lens can handle vibration when using a tripod
- Improved lens focus drive speed when an EF extender is attached
- New, state of the art coating
You can download and read the entire interview here. My readers know me as The Wildlife Ho-tographer and I have used Canon equipment for over three decades. Trying to decide which of these two lenses to add to my inventory. Leaning towards the EF 400mm Series III since it is slightly shorter and lighter.
Throughout the years, I have embarked on many worldwide photo shoots. Size and weight of equipment are major consideration on jeeps and bush planes. You can follow my travels on Facebook, Instagram and Twitter and see my equipment bag and works on MichaelDanielHo.com
