Operational differences between Arri SR3 and Arri 435 cameras for steadicam work
20 years old. Gear and prices may have changed since.
DisputedParticipants disagreed and reached no conclusion. Read the findings as positions, not as an answer.
What the thread found
- The 435 is heavier and significantly louder than the SR3.
- The 435 requires dedicated 24-volt power supplied through the sled or battery belt, whereas the SR3 typically uses onboard batteries.
- Focus requires greater precision and attention with 35mm film than with 16mm.
- Magazine capacity is shorter on 35mm than 16mm cameras.
- The 435 demands substantial electrical current, and high-speed ramping or overcranking may exceed what a Master Series converter can supply.
- Powering a 435 at maximum frame rates consumes batteries rapidly, potentially requiring six batteries instead of four to allow adequate recharge time between uses.
- Steadicam-specific accessories are essential for 435 operation in low mode, including steadicam magazines and a 100% video tap.
- The 435 performs significantly better as a steadicam camera when equipped with appropriate accessories.
- Start-stop control uses a 3-pin Fischer connector on the 435; using the 11-pin connector for this function can interfere with camera electronics and video assist systems.
Depends on
- Participants disagreed on whether the 435 start-stop control uses the 3-pin or 11-pin connector; some reported the 11-pin as standard on all 435s while others stated the 3-pin should be used.
- Some inverters cannot reliably power a 435 at high frame rates, though certain models have proven capable.
- The advice assumes typical commercial production setups with Master Series converters; power availability may vary with different equipment configurations.
- Discussion focused on 435 operation with steadicam rigs; sled setup specifics were not fully explored.
