FILMCITY HS-2 Follow Focus With Hard Stops
The HS-2 model uses a 0.8 pitch drive gear to deliver crisp focus adjustments for both cinema and still lenses. It features a durable CNC aluminum construction and a full-featured design with a flippable gearbox for left or right-handed operation. Best for shooters who require reliable, precise focus pulling in demanding environments and who favor a robust build for daily use on 15mm rigs. A potential limitation is that some users may prefer lighter gear for ultra-compact setups.
SmallRig Mini Follow Focus 3010C
This compact follow focus is designed for easy control on lightweight rigs. It weighs about 204g (7.2oz) and supports lenses up to about 114mm in diameter. It offers adjustable A/B stops, with a switch to lock AB stops for quick transitions. Best for mobile filmmakers and run-and-gun shooters who need a portable solution without sacrificing stop accuracy. Limitation: may feel underpowered for larger cinema lenses on heavier rigs.
Hersmay A/B Hard Stops Kit
This kit focuses on metal hard stops with scale pillar screws, designed to fit into various follow focus setups. It’s compatible with multiple rigs and provides stable A/B stop support. Best for users who want a simple, install-and-go solution to add or replace hard stops. Caution: compatibility with other brands may vary, so verify rod spacing before purchase.
SmallRig F50 Follow Focus
SmallRig F50 emphasizes a stepless dynamic damping lever and AB stops, built around a 15mm rod system with a rod clamp and gear ring belt. It supports 360-degree pulling and aims to minimize focus backlash with adjustable damping. Best for shooters who want precise, repeatable focus with a broad range of lenses and a smooth, controllable feel. Limitation: AB stops require complete locking to avoid friction noise.
SmallRig F60 Modular Follow Focus
The F60 offers wide-range, stepless damping adjustment from 0.6kgf to 1.8kgf, along with AB stops and a 15mm rod clamp with a snap-on gear ring belt. It’s designed for DSLR and mirrorless setups that demand refined damping and smooth focus transitions. Best for professionals who frequently switch lens types or use high-damping lenses. Caution: AB stops need to be fully locked to avoid friction noise during operation.
Nitze MF15D Follow Focus Kit
The Nitze MF15D kit includes multiple drive gears (0.8 Mod with 38, 43, and 65 teeth), A/B hard stops, and 360° infinity zoom capability. It features an adjustable rail above the 15mm rod clamp to fit various lens lengths. Best for versatile rigs that require gear reversibility and a complete set of A/B stops. Limitation: assembly may be more involved due to multiple components.
Buying Guide
What should you consider when choosing a follow focus with hard stops?
- Rig compatibility: Confirm 15mm rod compatibility and whether the unit clamps to your shoulder rig or cage.
- Gear pitch and teeth: 0.8 pitch is common; ensure the gear matches your lens gears for accurate engagement.
- Hard stops: Decide between fixed A/B stops or adjustable stops, and whether you need 360° infinite focusing capability.
- Damping: Consider whether you want adjustable damping with a wide range or a fixed feel for predictable pulls.
- Weight and portability: Lighter options suit compact setups; heavier builds may suit pro-level cinema rigs.
- Ease of use: Quick-release mechanisms and flip gears can affect how fast you set up and adapt on set.
- Maintenance: Metal construction generally offers durability; check for wear on clamps and gears after frequent use.
FAQ
What is the main purpose of a follow focus with hard stops?
To provide repeatable, precise focus adjustments by presetting exact focal lengths, reducing guesswork during pulls.
Do all these follow focuses support 360-degree focus rotation?
Many do, especially models marketed for cinema work; verify the product details if 360-degree rotation is essential.
Are AB stops adjustable on these systems?
Yes, several models offer adjustable AB stops for custom focal lengths, while others include fixed stops.
Is damping important for focus pulling?

Which kit is best for a travel filmmaker?
Compact options like the SmallRig Mini 3010C are ideal for travel, offering light weight and convenient AB stop controls.
Can these be used with both DSLRs and cinema cameras?
Most models are designed for 15mm rod systems used on both DSLRs and cinema cameras, but always check compatibility with your gear.
