How Fares the Battle?

Well, a few wrinkles have tossed themselves into the fray. As usually happens! 

A great feature for Nikon: Z bodies can upload 2Mpx images to the cloud. Does Lumix club do that as well? Hmm.. 

A quirk of the S1: note in the image that the LCD screen on top is active when power is off. That small drain (and perhaps others) will kill the camera battery in about three weeks of inactivity. Removing the battery will drain the small battery that keeps the clock and other settings working - and that battery is miserable to replace! Bummer..

One L-mount bummer is the lack of a sub-600-gram telephoto zoom. But since I now have primes at 200/4, 300/5.6, 400/6.3 & 500/8, how badly do I really need a zoom? 

And a Z-mount bummer is the lack of a 20-anything lens. They have Tamron's 70-300 (575g), sorta bulky but sufficient to fill the long end. 

Update! In searching for specs on the Vivitar (Kino) 2x converter, I found a Kiron 1.5x multiplier that would yield a 105-225mm f/5.2 - that would be nice! Since Kiron made the lens, it could prove to be a very good match.. and the 35-200 can move on. 

Curious that MY proposed kits each fail for lack of a zoom at one end or the other. Canon is just now adding its basic 70-300 and Sony hasn't - so it isn't just one mirrorless mount that lacks a lighter slower long zoom. Ya'd think that tiny Alphas and the S9 would make this a priority; clearly not, or at least ..not yet? 

So the full range S1 kit would be 20-60 + 70-150 + either a multiplier or an appropriate prime or two. The 2x matched adapter, but it makes for a slow 140-300/7.6 lens¹ - I feel less troubled by the 1.5x that stops at 225mm f/5.2ish. And we cannot forget that in either case the Nik-L adapter must be included! 

The Z6 would be the bulky [ftz plus 24-85G/vr] plus 70-300, and an 18-20mm prime placeholder. Sounds nice, and a prime or two.

So who wins this skirmish?

Z6, 24-300 + ftz = 1,860g

S1, 20-150, no 2x: 1870g

A Draw. 

Variations: One could use the 70-150 on both to open the weight gap, but then it's 80g vs 20-24mm. Or add the 2x adapter (weight unclear) and the S1 becomes 1/2 stop slower at 300mm (and manual focus vs Z native) for the added weight of the converter.

Round 3: video quick check

This was simply checking 4k30 rolling shutter, and settings were really different. I had to reshoot the Z6 after capping the iso at 8000, for unclear reasons its iso max was 16000! In the end it shot at 640, but the S1 chose 2500? I wasn't checking sharpness and color anyway - and for rolling shutter effect I preferred the S1. I believe the readout speed on the two sensors is pretty close .. (checking) .. they match. Another draw. But my tests suggest a slight advantage to the Lumix.
