Sigma is showing off a massive 200-500mm, F/2.8 zoom lens that weighs 88 pounds.
The modest update to last year's WX300 offers an easier way to connect to Android devices and a more powerful processor, but little else.
When it ships, the new lens will offer long-range sports and wildlife shooters some new competition, but it's not as fast a supertele as some rivals.
The third-party lensmaker's new supertelephoto won't cost much more than an earlier 200-500mm model with no image stabilization.
A built-in 1.4x extender pushes Canon's forthcoming 200-400mm zoom to a maximum of 560mm. Also: higher prices but lower weights for new 500mm and 600mm supertelephotos.
Sometimes size matters, and bigger telephoto lenses make photos of distant animals possible. Nikon's 800mm f5.6 lens will doubtless have a big price tag, too.
A mammoth pro lens with a built-in 1.4x focal-length extender is set for a 2012 debut, but Canon isn't promising anything yet.
If you crave a compact megazoom that gives you a lot of control over your results, look no further than the Fujifilm FinePix F900EXR.
Pricing not available
You get you what you pay for with the Canon EF 200-400mm f/4L IS USM Extender 1.4X: superlative performance and flexibility.
Just one feature differentiates Sony's two 20x compact megazooms.
