If you own the Nikon NIKKOR Z 180-600mm f/5.6-6.3 VR lens and shoot in cold weather, firmware version 1.01 is a critical update you need to install immediately.
Nikon released firmware 1.01 for the NIKKOR Z 180-600mm f/5.6-6.3 VR lens to fix focus inaccuracy issues at infinity when shooting at 400-600mm focal lengths in low temperatures, ensuring sharp focus performance for wildlife and outdoor photographers.
This isn’t just a minor tweak—it’s a fundamental fix for a problem that can ruin your shots when you need them most. Imagine tracking a bald eagle at sunset in winter, only to find your images soft at the 600mm end. That’s exactly the scenario this firmware addresses.
Having worked with telephoto lenses for over 15 years, I’ve seen how temperature affects optical equipment. Cold weather can cause metal components to contract and lubricants to thicken, leading to precision focus issues. Nikon’s quick response with this update shows their commitment to professional photographers working in challenging conditions.
In this guide, I’ll walk you through everything you need to know about this update, from understanding the issue to verifying successful installation.
What Problem Does Firmware 1.01 Fix?
The core issue addressed in firmware 1.01 is focus inaccuracy at infinity distances when using focal lengths between 400-600mm in temperatures below 50°F (10°C). This isn’t a slight misfocus—it’s a significant deviation that can render your telephoto shots unusable.
Infinity Focus: The point at which light rays from infinitely distant objects converge to form a sharp image. For telephoto lenses like the 180-600mm, precise infinity focus is crucial for wildlife, landscape, and astronomical photography.
Here’s what was happening: As temperatures dropped, the lens’s internal focusing mechanism would lose its calibration at the telephoto end. Photographers reported focus points shifting 2-5 feet behind their subjects, even when using autofocus systems. This issue was most pronounced in:
- Wildlife Photography: Missing critical focus on distant animals
- Bird Photography: Soft images even when AF confirmations show success
- Sports Photography: Out-of-focus action shots from the sidelines
- Landscape Photography: Distant mountains and features appearing soft
The problem wasn’t affecting all users equally. Photographers in warmer climates might never notice the issue, while those shooting in winter conditions experienced consistent problems. This regional variation explains why Nikon took time to identify and address the specific environmental trigger.
⚠️ Critical Note: If you’ve been experiencing soft focus at 400-600mm focal lengths, especially in cold weather, this firmware update will likely resolve your issues. However, if your images are soft across all focal lengths and temperatures, you may have a different problem requiring service.
Pre-Update Preparation Checklist (2025)
Before diving into the installation process, proper preparation prevents common issues. I’ve seen countless firmware updates fail due to simple oversights. Don’t skip these steps—they’ll save you time and prevent potential problems.
1. Battery Preparation
Firmware updates require stable power. A dying battery during the update can brick your lens. Ensure your Nikon Z camera battery is fully charged—at least 90% or higher. If possible, use a fresh battery or one you know holds a full charge. Do not attempt this update with a partially charged battery, even if it shows 70%.
2. Memory Card Requirements
Use a formatted memory card with sufficient space. While firmware files are small (typically 2-5 MB), formatting ensures a clean file system without corruption. Format the card in your camera, not on a computer, to ensure proper file structure. Remove all other files from the card to avoid confusion.
3. Camera Settings
Before starting, set your camera to manual mode and disable auto power off. You don’t want the camera shutting down mid-update. Remove any accessories that might disconnect during the process, including battery grips (unless they’re integral to your camera body).
✅ Pro Tip: Take a test shot before updating. Focus on a distant object at 600mm. This gives you a baseline to compare against after the update. Keep the RAW file for reference.
Step-by-Step Firmware Installation
Installing firmware for Nikon lenses is straightforward but requires attention to detail. Unlike camera firmware updates, lens firmware updates are handled through the camera body. Follow these steps exactly—deviating can cause update failures.
