Sony FE 600mm f/4 GM OSS test by Ole J Liodden:

My overall impression of this new telephoto lens is that it is extremely well made, fast, reliable and light-weighted. It is difficult to find anything to improve, maybe except the pricing. Hopefully I will have another chance soon to use the lens on an expedition to test it in different situations.

I made an attempt to make a size comparison between the new Sigma 35mm f/1.2 lens and other FE lenses. The leaked image actually shows the L-mount version. That’s why I matched the size the “A” logo between the leaked image and the current Sigma 35mm f/1.4 FE. It’s not 100% accurate but it should be very close…

What’s clear is that the new f/1.2 lens is both longer and wider than current FE lenses. You cannot cheat on physics :)

Next we have the size comparison between the Sony 16-35mm GM, the new Sigma 14-24mm FE (L-mount version on this image) and the Tamron 17-28mm FE:

Finally the size comparison between the compact Sigma 45mm f/2.8 FE (L-mount version on this image) and the Zeiss 35mm f/2.8 FE:

The new Sigma FE lenses will be unveiled tomorrow (July 11) at 9am London time! Stay tuned on SAR!
