Hey everyone! I recently made the jump to the L-mount system with a Panasonic Lumix S5II, and while I’m absolutely loving the camera body, I’m feeling a bit overwhelmed by the lens options. I’ve always been a huge fan of the Sigma Art series for their clinical sharpness and beautiful rendering, but I know the lineup is currently split between the older adapted DSLR glass and the newer 'DG DN' lenses designed specifically for mirrorless systems.
I'm trying to figure out which ones truly shine on this mount in terms of both optical performance and autofocus reliability. I've heard incredible things about the 85mm f/1.4 DG DN Art being a total game-changer for portraits, but I'm also curious about how the 35mm f/1.4 compares to the various 50mm options currently available. Since I do a mix of street photography and occasional paid event work, fast and accurate AF is a huge priority for me. I’m a bit worried about buying into a lens that might feel sluggish or overly bulky if there’s a better mirrorless-native alternative available.
For those of you who have been shooting L-mount for a while, which Sigma Art lenses do you consider the absolute 'must-haves' for the system? Are there specific models that offer the best balance of weight and performance, or any older ones I should avoid? I'd love to hear your real-world experiences!

In my experience, basically:
- Sigma 85mm f/1.4 DG DN Art for L-Mount: reallyyy sharp portraits. - Sigma 35mm f/1.4 DG DN Art for L-Mount: satisfied with street AF. gonna love these! peace

Sooo I just found this thread and honestly i feel u on the lens confusion! Basically, the most important thing to know is that for the S5II, you really want the 'DG DN' badge. It's the 'safe' choice because those lenses are built specifically for the newer phase-detect AF system, whereas the older DSLR glass can sometimes feel a bit sluggish or hunt during paid gigs, which is basically a nightmare... right? I've been super satisfied with the Sigma 50mm f/1.4 DG DN Art for L-Mount lately. Compared to the Sigma 35mm f/1.4 DG DN Art for L-Mount, the 50mm is a bit of a beast but it's literally so clinical and reliable for event work. The 35mm is definitely more 'street friendly' because it's slightly more compact and handles better for long days of walking around. I mean, i guess the 35mm is a bit more versatile if you're only picking one for now? Anyway, sticking with the native mirrorless versions is the best way to ensure your AF doesn't flake out on you. Good luck with the new kit! peace

Honestly, just stick with any newer Sigma mirrorless-native glass:
- Faster AF
- Better weight
They're AMAZING, so youll literally love them on ur S5II!! Any fav focal lengths??

Jumping in here to second the recommendation above!! honestly, if you're coming from DSLR land, you might be tempted by the older lenses because they're cheaper on the used market, but i've been there and it's a total trap. On the S5II, the native glass is where the magic happens for that phase detect AF. Unfortunately, i had issues with the older adapted EF lenses being way too front-heavy. It totally ruins the balance of the camera. Plus, the AF-C just isn't as good as expected compared to the DG DN stuff. Here is a breakdown of the best value vs performance for the L-mount: - **The Portrait King**: You mentioned the Sigma 85mm f/1.4 DG DN Art for L-Mount. It is literally the best lens in the system tbh. It goes for about $1,099 new, but keep an eye out for used copies around $850. It's super sharp and the AF is snappy enough for paid event work.
- **The 35mm vs 50mm debate**: I've used both and well actually... the Sigma 50mm f/1.4 DG DN Art for L-Mount (around $949) feels a bit more refined than the 35mm. But if you're doing street, the Sigma 35mm f/1.4 DG DN Art for L-Mount is about $799 and offers way better value than the huge f/1.2 version which is like double the weight.
- **A Budget Curveball**: Since you do street photography, look at the Sigma 35mm f/2 DG DN Contemporary for L-Mount. It's not an Art lens, but it's all metal, tiny, and costs only $639. Sometimes the f/1.4 Art glass is just too bulky for a casual walk and you wont even notice the difference in rendering if you're stopping down a bit. Basically, dont waste money on adapted glass cuz you'll just end up selling it in 3 months anyway. Stick to the mirrorless designs and you'll be golden. gl! peace

@Reply #4 - good point! honestly i went through a similar phase where i tried to save a few bucks by using an adapter with my old glass from a different brand. it worked okay-ish for a while but man, the moment i finally swapped it out for a native one designed specifically for mirrorless, it was like night and day. my current setup feels so much more balanced now. i used to get a bit of a workout just holding the camera for a two-hour shoot because the old stuff was so front-heavy. i actually ended up selling my old kit to a friend who still shoots dslr because i just couldnt go back. being able to trust the focus during a fast-moving event without worrying if the adapter is gonna flake out is such a relief. totally satisfied with how things are working now, even if my wallet was a little grumpy at first... definitely worth it for the peace of mind.
