Trolleys and River shots with EF-M primes

Yes, I've shot AMT 203 on the e/b Sunset Limited. The Yellow/Black livery should be interesting.

And I remember when TECO was yellow without the wraps....I'm really old !

I managed to get on the bike yesterday and do some shooting in the city. I got a few TECO trolleys and some river shots.

My goal was to see if the native EF-M prime lenses do better than the Canon zooms. I have found that the EF-M zooms have a lot of CA at the edges of the frame, which tend to blur and frizz out the detail, kind of spoiling the shots, and wondered if the primes do better.

Here are some of my images:

Full-spectrum Canon ,M200, Rokinon 12mm f2 lens, f4, BG3 dual-band filter, 15 degree hue shift

Full-spectrum Canon ,M200, Rokinon 12mm f2 lens, f4, BG3 dual-band filter, 15 degree hue shift

Full-spectrum Canon ,M200, Rokinon 12mm f2 lens, f4, Spencer 590 nm filter

(Unconverted) Canon M6ii, EF-M 18-150mm lens, f5.6

Full-spectrum Canon ,M200, Rokinon 12mm f2 lens, f4, Spencer 590 nm filter

Full-spectrum Canon ,M200, Rokinon 12mm f2 lens, f4, BG3 dual-band filter, 15 degree hue shift

Full-spectrum Canon ,M200, Sigma 16mm f1.4 lens, f1.4, BG3 dual-band filter, 15 degree hue shift

Full-spectrum Canon ,M200, Canon EF-M 22mm f2 lens, f4, BG3 dual-band filter, 15 degree hue shift

Full-spectrum Canon ,M200, Canon EF-M 32mm f1.4 lens, f1.4, BG3 dual-band filter, 15 degree hue shift

Interestingly, I found that using the BG3 dual-band filter resulted in less chromatic aberration and sharper images with the Sigma 16mm f1.4 lens at f4 than using the Spencer Camera 590 nm filter. This seems counterintuitive.... I'd expect the filter passing blue and IR to have more CA than the 590 nm longpass filter. Perhaps the 590 nm filter is allowing a lot more deep IR closer to 900 nm.
