Canon Canada has announced image stabilized 500 mm and 600 mm super-telephotos, saying the lenses are sharper and lighter than the standards they replace.
The EF 600mm f/4L IS II USM and EF 500mm f/4L IS II USM use two fluorite elements — the previous lenses used one fluorite and two Ultra-low Dispersion (UD) elements. Canon says the elements weigh less overall but perform better. Weight has also been shaving by using more magnesium alloy and titanium, plus the lenses use a smaller and lighter image stabilizer module.
In addition, a third stabilization mode, called IS mode 3 is available. This activates IS only when the shutter is pressed for exposure. Canon says this makes it easier to track a subject.
The EF 500 shows an 18 percent weight reduction compared to the lens it replaces, from 136.5 oz to 112.5 oz. The EF 600 shows a 27 percent weight reduction from 189.1 oz to 138.3 oz.
The Canon EF 500mm f/4L IS II USM lens is scheduled to show up in May, with an estimated retail price of around $10,000. You’ll have until June to save the roughly $12,600 needed to pick up the Canon EF 600mm f/4L IS II USM.
