Ive been using the S5II since launch and native glass makes a huge difference with that phase detect. These are the two I'm most satisfied with for wedding work:

• Panasonic LUMIX S 24-105mm f4 Macro O.I.S. has awesome range. The stabilization works well and it stays sharp.
• Sigma 24-70mm f2.8 DG DN Art L-Mount is my choice for low light. Its snappy and reliable. Native glass is way faster than adapted glass tho.

To add to the point above: in my experience, the native communication is what makes the S5II actually sing. I spent years fighting with adapter lag before finally switching.

• The Panasonic Lumix S PRO 24-70mm f2.8 is a beast for Seattle weather because of that sealing.
• Native linear motors handle phase detect way smoother than older motors in adapted glass. Seriously, skipping the hunt during the first kiss is worth every penny.

Quick reply while I have a sec... are you shooting this wedding solo or with a second body? If youre solo, your range needs are gonna be totally different than if you have a 70-200 on a second strap. Seattle venues can get pretty tight too. Since you're worried about AF hunting, you might want to consider these specifically for the motor tech:

• Sigma 24-70mm f2.8 DG DN II Art
• Be careful to get the Mark II. It uses the newer HLA motors. The phase detect on the S5II really needs that high-speed communication to lock on instantly during the ceremony, and the older Mark I just isnt as snappy.
• Panasonic LUMIX S 28-200mm f4-7.1 MACRO O.I.S.
• I would suggest this if you want one lens for the whole day and plan to use flash for the reception. It covers everything. The reason I'm focusing on the motors is that some older native zooms still use stepping motors. Those were fine for the old contrast-detect systems, but with the S5II, they can lag behind the phase detect sensors. That usually causes that weird micro-jitter or hunting you're seeing with the adapted glass. Native linear motors are basically a requirement if you want it to feel fast.

^ This. Also, if you're doing a wedding in Seattle next month, weather is probably gonna be a factor, so sealing matters just as much as the AF speed. Before jumping into a specific purchase tho, I have a couple questions to help narrow down the options:

• Are you mostly shooting the ceremony from a distance or do you need something that handles tight indoor reception spaces?
• Whats your actual budget for this lens since wedding gear costs add up so fast? Honestly, for weddings, weight is usually the real killer by the end of the night. If youre doing a 10-hour day, a massive zoom might wreck your wrist regardless of how good the phase detect is. It might be worth thinking about whether you really need that extra stop of light or if you can lean on the high ISO performance of the body to keep things lighter.

Gonna try this over the weekend. Will report back if it works!

Just caught this thread and wanted to chime in... Ive been through the ringer with the S5II since it dropped and honestly, the brand choice within the alliance makes a huge difference in how the AF behavior actually feels in your hands. I remember a rainy shoot last year where I swapped between a bunch of different native options and even though they all use the same mount, the way the stepping motors in some brands translate that phase detect data is just different from the high-end linear stuff. Some glass feels a bit more clinical while others have that micro-contrast that makes a wedding dress pop. In my experience, even within native L-mount, some brands communicate with the body slightly faster for burst shooting than others. Since youre heading to Seattle and clearly care about that hunting issue, are you more worried about the absolute weight on your gimbal or wrist for an 8-hour day, or is the edge-to-edge sharpness for those big group shots your main priority? Also, do you find yourself needing to jump to manual focus frequently during the ceremony or are you hoping to just let the eye-tracking do 100% of the heavy lifting?

> My old primes are great but the phase detect AF on this body feels weird with my adapted glass and it keeps hunting. Ive been shooting with the L-mount system for a long time and I have to disagree with the consensus that any native zoom will solve your issues. While native glass is superior to adapted glass, you need to be very careful about which specific motor technology is inside the lens. Honestly, my biggest caution for a Seattle wedding is the environmental sealing. Many popular zooms are telescoping, which basically acts like a vacuum for moisture when you are zooming in and out in the rain. I would personally prioritize a lens with internal zooming or a more modern linear motor. People usually recommend the fast f/2.8 glass, but in my experience, the f/4 constant zooms often provide a more stable autofocus experience with the S5II phase detect system. The heavier elements in the f/2.8 lenses can sometimes lead to slight overshooting in high-pressure situations. Just something to think about before you drop the cash.
