The MTF chart of this new Nikon looks superb at the long end, but still it's 10% heavier than the older Sigma 120-300 /f2.8 (itself no lightweight) and over 3x the price !
The current Sigma 120-300 f2.8 Sport lists with just under 3.4kg, so the Nikon is in the same ball park. Price wise the gap is similar to other Sigma vs Nikon/Canon stuff
In comparison to that Sigma here's how they stack up:
Sigma - 23 elements (2FLD) / 18 groups, 1.5m cf, 2.95kg, 124mm dia × 291mm L
Nikon - 25 elements (2FL) /19 groups, 2m cf, 3.25kg, 128mm dia × 304mm L
It's a heck of a cost to pay (both in terms of $ and weight) for a bit more sharpness across the frame at 300mm, and better CA correction.
If Nikon brought this in at 2.5kg, I think discussion turns to the high image and build quality and commensurate price ......
At ~2kg I think it would've caused a sensation ! :king: o
The weight will be determined by the construction requirements for such a lens, lots of lenses and a lot of them are large diameter. Unless a lighter material for lenses is invented that can deliver the image quality, or fresnel elements are used the weight is not going to be lower.
As it is, I suppose there might be the odd giant ex-NFL /NBA, player turned Pro photographer on some fully funded generous payroll somewhere who might purchase one ........ :cat:
Chosun :gh:
