p.4 #1 · Prices of the Z 600mm f/6.3 PF and Z 400mm f/4.5 after Sony's announcement.
My first long lens was Nikon 600mm f/5.6. That lens weighed 6.2LB without AF and VR. Now look at Sony 300/2.8 (600/5.6 With 2x). I remember a 12 or 13 LB 400/2.8 AF lens in 2000's. So newer design and materials made lenses lighter for sure. But usually same generation lenses from all manufacturers had similar weight so far. Look at current 400/2.8 from Nikon/Sony/Canon. They share same weight and size (Nikon’s built-in TC added few ounces). Nikon’s 400/4.5 (which I have) came out in 2022 I think. So I kind of believe Sony could shave off few ounces from 400/4.5 (I have it in pre-order). However I too have some doubts about their 600 especially without PF elements. I'm wondering if they took 400 design and made some changes to make it 600. Need to see independent reviews (No the sponsored ones).

Never heard anyone grunble about the weight of the 600PF it's still a crazy light 600mm prime. I'd still pick the 600PF over the Sony 600 6.3GM. why? Look at the number of elements between them, physics still apply. The Sony has far less elements seated closer together, meaning it will not have internal corrections that the Nikon has, I'm betting it's not as sharp, worse bokeh (I see it in all samples I've reviewed), distortion and chromatic aberration exist. I wanted something lighter than the 180-600 , with very high IQ. The 600pf is exactly that. I don't understand how some people suddenly find a light lens "heavy" after another competitor releases one a few hundred grams lighter. At the end of the day they're both light so it doesn't matter, unless you have some serious physical issue, where I would then say you should start some weight training! We aren't talking about super heavy F4 tele primes here, these are featherweight primes. The Nikon 600pf was light before the Sony announcement and is still light today lol ...Show more →
