Canon EF 600 f/4 L IS

[Romy Ocon]

Features:

The world's first 600mm lens with an Image Stabilizer for added steadiness and sharpness when working at slower shutter speeds. It shares the same lightweight, weather-resistant construction as the 300, 400 and 500mm IS Super Telephoto lenses, as well as their improved control layout, improved weight distribution, and mechanical manual focus.

• Flourite & UD elements eliminate secondary spectrum chromatic aberration
• AF speed is the fastest in the world
• Full-time manual focus override
• AF Stop function shuts off autofocus when an obstruction appears
• Dust & moisture resistance made exceptional by magnesium alloy lens barrel and new rear gasket at lens mount
• Two-stage image stabilization; dual-axis camera shake correction or vertical axis only(for panning)
• 3-stage focus limiter
• Focus preset function allows for returning to a specifically set focus by turning a ring in front of the focus ring

Hand held? Wow...... this lens is the ultimate in reach among the current EOS stabilized lenses - 150 mm diameter of the main element vs. 143 mm of the 400 2.8 IS and the 800 5.6 IS.

Yup, that's right, handheld. No time to set-up the tripod. One deep breath each shot. I think this 600 has almost the same weight as the 400 2.8 L IS. The latter a bit heavier if I not mistaken.
