New Sigmas are coming ...
Gonna send in some drones. DJI has one with a Hasselblad camera, hope this will find a way through the dustclouds which a 5000 mm could not penetrate. Same goes for photographing Lions. Or make eye to eye portrait of a giraffe.
New "leaks" (in three days or so Sigma will just confirm...):

2.7 kg for the 60-600
1.2 kg for the 40/1.4  Confused
You were not interested in the 40 anyway ;-)
Chief Editor -

Doing all things Canon, MFT, Sony and Fuji
I'm not sure if it's cheaper than a membership in a gym...
1.2 kg for 40mm f1.4 is a bit... daft. Their 50mm f1.4 weighs 815 grams and their 24mm f1.4 weighs 665 grams. Their design process seems to make wrong turns at times?
The MTF implies that the 40/1.4 is insanely good. Not sure how it'd compare to an Otus but it may be close (focal length differences notwithstanding).

And get the whole equivalence thing splashed in your face? Smile

Of course you do need to understand equivalence, to understand what the 3.8-247.0mm on the front of the Canon SX70 HS means (example of a superzoom compact). Without any reference, no one can make out what the meaning is of that 3.8-247.0mm. But with a 135 format reference... it is equivalent to a 21-1365mm FF lens.
See, you do need the equivalence thing splashed in your face.
40mm f1.4 weighs 1.2kg
Is this for real?
Wait, that is real? I thought people were joking.
16 elements in 12 groups, 82mm filter (roughy the front element diameter) vs 13 elements in 8 groups, 77mm filter for the 50mm f/1.4

The 50 is 0.8kg so with a bigger front element and more glass ...

The 40 is also much longer (131mm vs 100mm).

BTW, the MTFs are clearly substantially superior compared to the 50 ...
