What are the best compact prime lenses for L-mount street photography?

Question

I’ve recently made the switch to the L-mount system with a Lumix S5II, and while I’m absolutely loving the sensor performance, my current 24-105mm zoom is just too bulky and conspicuous for the kind of street photography I enjoy. I find that when I’m out in crowded areas, the large lens makes me feel a bit too 'obvious,' and I’m really looking to move toward a more discrete, minimalist setup.

I’ve been doing some research and the Sigma ‘I series’ primes, like the 35mm f/2 or the 45mm f/2.8, seem like they might be the perfect size. However, I’m also curious about the Panasonic 1.8 series—are they actually small enough to feel 'compact' in the field? I’m looking for something that balances well, has snappy autofocus for quick snapshots, and ideally fits into a small sling bag without a struggle.

I’m a bit torn between sticking with autofocus or looking into some manual M-mount glass with an adapter to keep the profile even smaller. For those of you who regularly shoot street with L-mount bodies, which specific compact primes have become your go-to favorites for staying low-profile while maintaining great image quality?

bulky gear kills the street vibe. basically, for discrete shooting: - Sigma 45mm f/2.8 DG DN Contemporary tbh, it's way more compact than those lumix 1.8 primes. gl! 👍

yo, i feel u on this. the Panasonic Lumix S 24-105mm f/4 Macro O.I.S. is a killer lens but it basically screams 'I AM A PHOTOGRAPHER' when ur out on the street lol. after shooting L-mount for years, i think the move is definitely the Sigma I-series if you want that discrete vibe.

basically, the Sigma 45mm f/2.8 DG DN Contemporary is your best bet for a budget-friendly setup. you can actually find them used for around $250-$300, and it's tiny enough to fit in literally any sling. the AF is snappy enough for street, tho maybe not as fast as the native Lumix glass... well actually, on the Panasonic Lumix S5II with phase detect, you wont even notice a difference.

the Panasonic Lumix S 50mm f/1.8 is also a fantastic value at about $350, but it’s actually a bit longer than the sigmas. it’s light, but not necessarily 'compact' compact. for a low-profile setup, that sigma 45mm is reallyyy hard to beat. gl!

Yo, late to the party but I totally get the struggle with that big zoom... it literally screams 'expensive camera here' which isn't great for safety or being discrete. Honestly, when I'm out in busy spots, I've found that having a smaller profile keeps people from getting defensive or, worse, eyeing my gear for the wrong reasons. Staying low-profile is lowkey the best security measure you can have.

Check out **CameraSize.com** if you haven't yet—it's a great resource to visualize how these setups actually look on the S5II body before you spend any cash. Also, the **L-mount Alliance** site has a huge list of every compatible lens which is super helpful for finding those hidden gems from smaller manufacturers.

Basically, I'd say just get any of the **Sigma** compact primes. They're built like tanks and look way more 'old school' and less 'paparazzi.' If you really want to go tiny, definitely look into adapting **Leica M-mount** glass or even some of those **third-party manual lenses** from brands like TTArtisan. Since there's no AF motor, they're basically pancake-sized and make the camera feel so much more balanced in a small sling. I've been shooting with a tiny manual setup lately and I'm so satisfied with how it handles... it's just way less stressful than lugging around a huge zoom. Plus, you get that tactile feel which makes the whole experience way more fun. Anyway, hope that helps! gl!
