I just got this from a completely new source. So there is a VERY big chance it might be wrong and complete BS. But I am posting it nevertheless because I am curious to learn from you if actually an E-mount to E-mount Speed booster would be even technically possible to make! Here is what that message contained:

APS-C will be pushed BIG in the near term.  Better high-end APS-C glass, and higher resolution sensors.  FX-30 is recent proof of this.  Will Sony release a A6800 or A8000 ??  I don’t know, but the next rumor is ‘quasi’ related to the APS-C rumor.

Second:
Sony will release a 500/4 lens, and a speed booster in 2023.
The new FE lens is coming as the global chip shortage is almost gone. (Chip bloat is coming)
It won’t quite be 500mm, but actually 485, but sold as a 500mm.  F-stop will be 4.12, and not a 4.0, but this new GM lens will be sold as a 500/4.  I have no idea on pricing, but probably between €7k and €9k.

Speed Booster will concentrate Full-Frame FE down to APS-C E-size.  Speed booster is intended to boost the APS-C camera market.  Hopefully the E-Mount speed booster will work for ALL FE lenses, not just GM lenses.

Like I said, E-mount to E-mount Speedbooster really sounds a lot like BS…but if it would be technically possible I actually think this would be a great product to make!

The images as well as MTF charts of the upcoming Sigma 60-600mm F4.5-6.3 DG DN OS Sports have now been leaked by Nokishita (via digicame-info).

We already reported about specs and pricing in this article.

The Sigma 60-600mm lens for Nikon F and Canon EF is available for about 2000 Dollars/Euro here on Amazon.

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.

Rumored Sony 20-70mm f/4.0 specs:

• sharper than the first generation 24-70mm GM
• very little distortion
• Price 1.599 Euro
• Announcement on January 17

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!
