It's unfortunately very difficult to find native autofocus lenses in this price bracket. The market's quite limited. If you can manage manual focus, the 7Artisans 15mm f/4.0 ASPH Full Frame Lens for L-mount is a decent budget solution. It avoids the autofocus hunting issues you'd see with cheap adapters, though it lacks electronics entirely. It isn't as convenient as native glass, but it fits your budget for Zion.

I would suggest looking at these two options. Finding native wide glass under 450 is difficult, so you might want to consider used equipment or manual glass.

• Panasonic Lumix S 18mm f/1.8: Best native autofocus, tho it requires buying used to stay in budget.
• Venus Optics Laowa 14mm f/4 Zero-D: Extremely wide and within budget, but be careful since its manual focus. Make sure to practice before Zion so things dont go wrong.

^ This. Also, been thinking about your Zion trip and honestly, you gotta be careful with the adapted glass route if you're doing any video. I tried an old Canon setup with a cheap adapter once for a hike and the focus hunting basically ruined my footage... it kept pulsing right when the light was perfect. If you're really stuck on the $450 limit, I'd suggests checking out the Samyang AF 14mm f/2.8 L. It's a native lens so the autofocus actually communicates with your S5 properly. It's usually a bit over your budget brand new, but I've seen them go for around $400 on the used market or during big sales. Just make sure to check the corners if you buy used because quality control can be a bit hit or miss with Samyang sometimes. Another weird but fun option is the TTArtisan 11mm f/2.8 Fisheye L-mount. It's manual focus, but since it's so wide, almost everything is in focus anyway. I used it for some canyon shots and it's surprisingly sharp for the price, tho you'll get that fisheye distortion. Just make sure you're comfortable with that look before you commit because it's not for everyone but it definitely fits the budget.

Just saw this thread. Like someone mentioned, finding native glass for the L-mount under $450 is a bit of a challenge since the system is still maturing. I have shot with the S5 for quite a while now, and Zion is exactly the kind of place where you want every millimeter of width you can get. Before I point you toward a specific lens, I gotta ask... are you mostly doing handheld video or vlogging where you need the autofocus to track you, or is this more for tripod-based landscape stuff? In my experience, for wide landscapes, you can usually get away with manual focus because the depth of field is so deep anyway. If you can handle manual, it opens up a lot of doors. If you really need to stay under that $450 cap, here is what I would look at:

• Sigma 20mm f/2 DG DN Contemporary L-Mount
• If you buy used, you can definitely find this for around $425-$450. It is sharp as a tack and the build quality is way better than the kit lens.
• 7Artisans 12mm f/2.8 II L-Mount
• This is a manual lens, but it is super wide and very budget-friendly. It is great for those massive canyon walls where 20mm still feels tight. I have tried many setups over the years and honestly, the Sigma 17mm f/4 DG DN Contemporary L-Mount is the one I would personally save up for, but you might find a deal on a used one if you check the forums today. It is tiny and perfect for those long hikes up to Angels Landing tho...

> I read about some adapted EF glass too but the autofocus sounds like a total nightmare for video and I'm worried it'll just hunt the whole time. I totally agree with Michael about the AF situation on a budget... its a huge gamble for video. I remember hiking through the Narrows a few years back with an older adapter and the internal communication lag made it basically unusable for tracking shots. You really gotta be careful with non-native electronics in those dusty canyon environments. If the 10-pin contacts get even a little grit, your aperture control can just lock up on you. I would suggest looking into a rental for the week instead. It keeps you under that 450 limit but gives you the weather sealing and reliability you actually need for Zion. It really isnt worth the risk if the gear fails halfway through the trail.
