## 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 However, it does come with some outdated components and lacks advanced features like Dual Pixel CMOS autofocus, making it less ideal for cutting-edge photography.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.
