I got some good news about the upcoming Sony 20-70mm f/4.0 lens. First of all I can now confirm it has constant f/4.0 aperture and that lens will be announced next week on Jan 17. I also have been told the lens is optically superb with very little distortion (good news considering the 20mm at the wide end) and sharpness that beats the performance of the first generation 24-70mm GM.
Sigma confirmed it will announce “new products” on January 12th. Of course we already know that they will announce the new 60-500mm f/4.5-6.3 sports lens for Sony E and Leica L mount. Here are the specs:
60-600mm F4.5-6.3 DG DN OS | Sports
Lens construction: 27 elements in 19 groups
Minimum Focus Distance: 45-260cm
Maximum magnification: 1:2.4
Number of aperture blades: 9 (circular aperture)
Filter diameter: 105mm
Size: φ119.4mm x 279.2mm (281.2mm for E-mount version)
I got word form one source that Sony will announce the new 20-70mm f/4.0 G lens on January 17. The price should be around 1600 Euro/Dollars. This is nearly twice the price of the Zeiss 24-70mm f/4.0 lens. But the new Sony lens will be the world’s first standard zoom with 20mm at the wide end. For some photographers this lens could be enough wide to replace the classic duo: 16-35mm and 24-70mm zooms. Moreover I have been told the Image Quality on this lens is very high and definitely a big step forward compared to the Zeiss.
I got no info about other new products but there is a fair chance the new 16-35mm f/2.8 II GM and maybe a new camera will be announced soon after sometimes in February!
