"Vintage Look" seems to be the opposite of "Sterile Look".
I tend to use "Classic Design".
Digital sensors require that light fall much more directly on the sensor, requiring changes to optimize a lens. This is similar to changes in lens design for SLRs for shorter focal lengths. Wide-angle lenses are retro-focus design, to clear the mirror. Side-Effect, light falls directly on a digital sensor. Expand the concept to change the optical design of lenses for Digital cameras to a long/drawn-out optical path, and use all the extra elements to eliminate aberrations.
Rangefinder film cameras allow use of classic lenses. Leica digital cameras have special sensors designed for classic lenses, optimized for accepting light coming in at sharp angles. SO- if you want the "vintage Look", no camera better to use the lenses than your Canon P.
Interchangeable lens 35mm rangefinder cameras made their debut over 90 years ago when Leitz introduced the Leica II and Zeiss debuted the Contax I. The first lenses for these cameras were Tessar formula lenses of modest speed. The 5cm F3.5 Tessar was produced in Contax RF mount in 1931, and was...

This is with my 1936 Carl Zeiss Jena Sonnar 5cm F1.5, one of the first lenses with coated optics. From the test batch.
The Sonnar design is "Asymmetric", rear element sits close to the image plane. Light comes in at steep angles to the sensor. This is on the Leica M9, CCD sensor optimized for lenses like this.
On film, Canon 50mm F1.5 at F2. This is Canon's Sonnar formula lens.
Center Sharp, low astigmatism, high Coma, high field curvature. Higher contrast as there are less optical surfaces.
