I'm a Zoomer, I hate fixed lens from the film era: Why I bought Viltrox 20mm, 14mm, 9mm !!

Z30 + Zf >>> Zooms range cover 15mmE-1260mmE

For the interiors shot like a museum, historical buildings, I've used Z30 & 10-20DX + Zf & 24-200Z

But what I sometimes miss is a wider lens + aperture.
10-20DX starts a 3.5 and goes to 4 very soon.
24-200 on Zf is fantastic even in the dark ... but starts at F4 and 24mm is not enough in some situations

Let me test if I'm comfortable using fixed lenses, with a 20mm F/2.8 that will be dedicated to Zf,
... and the duplicate range 14mm f4 / 9mm f2.8> 13.5mmE to have that range on both cameras @20Mp.
Note: the 14mm is F4, so I'm wondering if there will be enough light, but if I use the 9mm on the Zf, it gives me 13mmE, at only 10Mp.

Testings will begin in two weeks, when the lenses arrive!

Expected:
wide range @20mp, better Light for darker situations
Bonus + 14mmm become a 21mmE on Z30, so both camera can cover 14mm + 20mm

( 20mm 130€ + 14mm 149€ + 9mm 149€ - not bad I suppose )

If it is available for your camera lens mount or is adaptable, the Sigma 17-50mm with it's constant f/2.8 might suit you.

Thanks.

All three Viltrox are Z mount, and they will sit alongside, not replacing the AF-P10-20DX I already own.

I also checked and tested a 450€ used copy of the Tamron AF 15-30 G1 FF W O W , but it weighs 1.2Kg.
It would have been a "special use" lens only, kept waiting in a special bag, like the 180-600Z does.

Under 450€, if I find ALL of them useful, the three Viltrox will fit in my actual bag, adding a weight below 0.5Kg!
