Got it. I was reading it as 43... like 43mm or something. Just dumb on my part. I ordered an adapter and the lens. I have always been fascinated by ultra wide angle lenses and wondered hold folks could produce some of the very close ultra-wide images of like a bug or butterfly large (super close) and everything around it in good focus. I will check it out. Thanks.

The Laowa 15mm f/4 Wide Angle Macro is supposed to be excellent for ultra-wide macro with the background in focus. Does anyone have experience with that lens?

People tend to forget, and might I say with good help from the advertising, that depth of field becomes largely independent of focal length when you get into the close-up region. Thus we should NOT think of a 'macro' image with background in focus, as this is not possible (except using camera/lens movements, but then the issue is with the objects taller or lower than the intersection of the focal plane to the subject).

Instead it's about the illusion created by a background blur with smaller circles of confusion. Thus the background with a short focal length lens  will not look as a pure wash of colours, there will be unevenness to it and in some cases the eye 'resolves' enough of the blur to identify some part of the background. However, by no stretch of imagination the background will become 'in focus'.

I see no contradictions to my general statement here. 'Recognisable' and 'sharp' are different concepts.

Of course you (Birna) are correct. Maybe we should just call the background of a wide angle macro shot "less unsharp".

That would go a long way towards clarifying any issue, definitively.

The image circle won't be bigger.
