Viltrox previously released one of their best character lenses: the 28mm f4.5 pancake. First, it came for Sony E mount. Then it came to Nikon Z mount. This lens is something really unique in that it boasts a built-in lens cap, autofocus, and a very small size. It also has a fixed aperture — which is perfect because I feel like most digital photographers have forgotten how to use the aperture setting on their cameras. Today, it launches for Leica L mount. Therefore, it also comes to one of the most perfect cameras for street photography: the LUMIX S9.
This review will be shorter than all the others and in a completely different format because this lens isn’t about sharpness or any of that other stuff that people like to fixate over way too much. Just like our Nikon Z and Sony E mount variants, this is a lens that’s all about the experience more than anything else.

And just like the other lenses, it’s going to be super affordable at only $99. Mounting this lens to the L-mount is simple and straightforward — or at least it will be for most people. I put a Kolari Vision protective filter over the sensor of my Leica SL2s. The Viltrox 28mm f4.5 goes deeper into the camera body, so it will smash up against the filter. I could take the filter out, but I instead decided to put it on my Lumix bodies.
It’s perfect on the S9 — and it’s much smaller than the LUMIX 40mm f2 and the TTartisan 40mm f2. Like the other variants though, it’s not weather sealed. If you don’t care about that, then good for you. I, on the other hand, think that every product these days should have weather resistance and that there is zero excuse for it in 2026.

Aside from this, Viltrox has to be given a lot of credit here. They’ve created a lens that’s unique instead of trying to copy every other camera brand out there. No one has anything like this. More importantly, Viltrox is part of the L-mount alliance. With that said, this is probably the perfect camera system to have the 28mm f4.5 on.
Otherwise, there isn’t much to say about this lens. So how does it perform? Well, there’s character for sure — a lot of it. You’ll get lens flare, softness, and even some things that traditional photographers and those pretending to be will call imperfections. I call it vibes.

Additionally, LUMIX will ultimately end up being the ox that pulls the Viltrox shaped plow here. Specifically, if you’re using LUMIX and you’re not using the Real Time LUT feature, then what are you even doing? I used it with a Kodacolor 200 render and one that’s designed to look like a Leica look. The Viltrox 28mm f4.5 is quite a contrasty lens for what it’s worth. It can be sharp. It can also be really flare-laden. But overall, I think that the big thing here is the experience. With the lens attached to the Lumix S9, I don’t think that there’s any better combination for street photography that’s compact. Most importantly though, there is no option that’s also full-frame and this small.
So why didn’t I actually use this for street photography? Because I’ve done it in the Sony variant review. The S9 can do it, without question.
We recommend picking this lens up if you’re an L-mount user. Here are some extra image samples.
