The impossible comparison: New $5100 Sony RX1rIII vs the $2700 Sigma BF+lens size comparison

Sony recently unveiled the new RX1rIII, currently the most compact full-frame camera with a fixed lens on the market. And because of its price tag of $5,100, it’s causing quite a stir on the internet. Before you yell at me: I am aware that this is like comparing apples and oranges. But I found one aspect interesting: the Sony RX1rIII is not that much smaller than the Sigma BF with a Panasonic 18-40mm lens:

Yes, I know, folks, Sony has a built-in EVF (even if it only has 2.36 million pixels), which would be very handy on the Sigma BF. But both cameras have things in common, such as the lack of IBIS and no tiltable screen. And yes, in this picture, the Sigma is using the $500 Panasonic 18-40mm lens, but maybe one day Sigma could release a lens like the Nikon 40mm f/2.0, which is basically the same size as the Lumix zoom lens:

What I’m trying to say is that the BF could come very close to the Sony RX1rIII, which costs twice as much, with a beautiful f/2.0 pancake lens. In the future, a Sigma BF2 could even be equipped with an integrated EVF, which would certainly make us photographers very happy!
