Sigma claims the new zoom will deliver the same optical performance as a prime lens.

Definitely an interesting lens but it weighs 3,985g (8.79lbs), at least you could save on gym membership!

hurts my biceps just thinking about such a heavy lens!

 

[RogerSmith]

there was a time when I would have been keenly interested, but the weight is a consideration plus limit to 15FPS and no TCs will work (unless that has changed but I doubt it, its Sony's brand protection backstop)

I won’t be buying this, but the young and fit may find this an interesting option, especially at f/4 throughout.

A 600mm prime is typically f/4, and the Sony and Canon RF 600mm f/4 primes are a bit over 3kg, while the Nikon is something like 3.8kg. This lens is heavier than those, but it’s a zoom. To be honest, for a zoom, that’s surprisingly close to the prime.

It would be interesting to try out ... would be good for field sports (track, American football, "European kickball" , cricket) ...

a lens for the mono pod tripod brigade,shame it has sonys limitations be ok for me and my photo hide shooting or motor sports ,but can not see me carrying it up cad west ,or walking with it on the big reserves casual shooting ,and the sony 400-800mm has taken the shine of it a bit ,being half the cost 1.5kg lighter and no limitations ,but you are not using a t/c with sony 99.9 % of the time ,sort of great lenses but both have big drawbacks ,to be honest a second version of the 200-600mm makes a lot sense maybe make it 5.6 at the long end and with xd linear motors and a true 600mm not a 570mm or what ever it is on existing lens

Can they make it a true 600mm? I thought the shortness at MFD was due to it being an internal zoom?

yes when reviewers compare the 200-600mm against the 400-800mm you can see the difference ,the 400-800 changes aperture at around 588 from 7.1 to f8 duade patton compared 600mm of the 200-600mm at 6,3 against the 400-800mm at 588mm 7.1 the new 400-800mm showed a longer reach also the 200-600mm with a 1,4tc which should be a 840mm was still short of the 400-800mm at the 800mm ,this is around the minimum focus distance though ,where as my sigma 500mm 5.6 almost matches my 200-600mm at mfd ,it annoys me manufacturers do not explain this ,so in turn the 200-600 has focus shrinking close up ,not a true 600mm more like 570mm .

Lens names are generally around the actual focal length. These are only e-mount patents but all the other mounts have the same type stuff.
The 70-200GM 2 is actually 72.14-193.95
Tamron has a patent for a 200-800 that would actually be 205.426-774.302
Sigma has a patent for a 500 f/5.6 that is actually 485
Sony 135mm is actually 131

Good point.

Apertures are rounded, too - f/1.4 should be f/1.4142... (square root of 2) - all the full stops between the powers of 2 are rounded (f/2, f/4, f/8 etc are not). f/5.6 is really 5.65685 - should really be f/5.7, and f/22 should be f/22.6, so it's really f/23.

I thought it was interesting to see several reviews coming from Australia - guess we have the light to make f/8 work well? It's still summer here (well, nominally it changed to autumn today, but I think it's more accurate to say summer covers December to March).
