Crop zoom

Excellent. Does it also work with the TTA 40/2?

No. It may be that the TT needs a f/w upgrade to enable that because the crop zoom is grayed out in the menu. I should clarify that crop zoom is available but you just can't assign the focus ring to adjust the zoom for the TT 40mm, currently.

Many thanks for letting us know.

I'm a recent S9 buyer and just added the 50/1.8 to my 18-40mm. This is probably not news to experienced panasonic users, but I've discovered with the 50mm that if I have crop zoom turned on and assign the zoom function to the focus ring (whilst in AF mode), this effectively turns the prime into a zoom lens, the zooming achieved by turning the focus ring. Very clever indeed.

All this talk about too many megapixels!! This is why we need sensors with more density. Love the versatility, you just taught me a new trick.

Indeed, that‘s a nice feature. My Viltrox 16mm f1.8 acts like a 16-33mm zoom

I wonder if this would work with a zoom lens whereas you could use the optical zoom and then crop at different focal lengths?

The menu option called hybrid zoom does something similar with Panasonic zoom lenses. Whether it works with £rd party lenses I could not say.

I was thinking to use them independently, not that it’s necessarily practical or needed, but when I do hybrid zoom, I assume my resolution is decreasing all across the range incrementally.
So I guess I could use a 24-105 and maintain resolution then use crop zoom,…you know, it just occurred to me

Why would I use crop zoom at any focal length under 105. I suppose crop zoom would be sufficient to work at 105.

Now I’m curious. Does hybrid zoom reduce resolution before maximum optical focal length is selected?

I would enable it and try it. I used hybrid zoom with the Lumix 18-40 and the zooming was very seamless. I think the resolution is normal up to the maximum optical focal length and then it gradually reduces as you zoom past the max optical focal length.

From my understanding that's how it works - by reducing the resolution.
Using a zoom lens in my opinion it makes sense to hybrid zoom when the max. focal is reached.
