Published: September 16th, 2024

Pros

  • Suction power is strong, comparable to or better than other brands tested
  • Rarely requires manual intervention, runs multiple times a day smoothly
  • Rubber brush rollers are superior for pet hair and agitating carpet
  • Support for future software updates like Keep Out Zones
  • Not necessary to empty the bin frequently due to the dirt disposal system
  • Responsive and custom cleaning via Alexa integration
  • Works well in dimly lit conditions (with initial training runs)
  • Excellent navigation and persistent mapping for efficient cleaning

Cons

  • Not capable of operating in complete darkness without smart lights
  • Shorter battery life compared to some competitors, requiring strategic scheduling
  • Old components used in the design and features
  • Lacks the Dual Pixel CMOS autofocus found in other models in the lineup
  • Minimal updates beyond the sensor upgrade
  • Autofocus and metering systems date back to 2009

Bottom Line

The Sigma 105mm f/2.8 EX DG OS HSM Macro lens is a solid choice for photographers looking for strong performance and efficient operation, particularly in well-lit environments. However, it does come with some outdated components and lacks advanced features like Dual Pixel CMOS autofocus, making it less ideal for cutting-edge photography. For those needing better performance in low-light conditions or more updated technology, considering alternative macro lenses might be beneficial.
