Weather sealing is incredibly important not only for inclement conditions, but dust-resistance. What’s more, it helps your camera gear work for a longer period of time. Lots of brands say their cameras have weather resistance. But only one really makes the best full frame camera gear with weather sealing. It’s Leica! And you’ll be surprised to see the reasons why!
Understanding LEica LEns Nomenclature

Some things about Leica SL lenses might not be very clear. So here are a few things worth quickly explaining:
- Summicron: Leica’s designation for a lens being an f2 maximum aperture
- SL: Meaning the lens is designed for full-frame L-mount cameras
- ASPH: Aspherical lens elements
- APO: Apochromatic design
- M: Designed for full-frame M-mount cameras
- Noctilux: Faster than f1.4
- Summilux: f1.4 through f1.7
- Summarit: f2.4 and f2.5
- Elmarit: f2.8
- Elmar: Around f3.4 to f4
- Summaron: f5.6
- Telyt: Long telephoto focal length
Understanding the Best Full Frame Camera Gear with Weather Sealing

Here’s what you need to know about the best full frame camera gear with weather sealing:
- You’re probably looking at this article and wondering why there are tons of wet cameras and lenses. That’s because we hold manufacturers to their marketing claims. Leica SL products have an IP durability rating most other camera manufacturers don’t offer. To that end, we need to ensure that the products can work according to their marketing claims. With that said, these are genuinely the best. The full frame camera gear with weather sealing presented here will be incredibly reliable.
- We’re specifically recommending Leica SL lenses in this roundup. Those lenses are for L Mount. They work with any Leica L-Mount camera and any Leica TL camera.
- Why are these the best full frame camera gear with weather sealing? Well, besides the IP durability, we’ve actually used this stuff in rough conditions and they’ve never failed us.
- All the best full frame camera gear with weather sealing are made by Leica. And they’ve done a great job with that too!
- These lenses have a metal exterior, so they’re durable enough to handle lots of abuse.
- Leica SL lenses are all autofocus. You can zone focus with them, but they’re not going to work the same as Leica M-mount lenses. Granted, there are some positively wonderful Leica M-mount lenses that you’ll be happy to adapt to the SL system. But you’ll lose autofocus, the IP-rated durability, and the overall feel of the package.
- On the Leica SL2, the Leica SL Prime Lenses will render their sharpest images because of the resolution of the sensor. Keep this in mind when doing things like printing photos of products for clients or retouching.
- On the Leica SL2-S, the Leica SL Prime Lenses will focus faster and help passionate photographers in low-light situations better. Our Editor in Chief uses the Leica SL2-S as his main camera for most situations.

In our review, we state:
