Tamron vs Sigma Lens Specs
Focal Length Range
The Tamron 150-500mm offers a massive zoom range. It covers ultra-telephoto distances, ideal for wildlife or sports. On APS-C bodies, this becomes 225-750mm equivalent. The Sigma 30mm is a prime lens. It provides a fixed 30mm focal length. This is a wide-angle view for Sony E-mount cameras. You cannot zoom with the Sigma. You must move your feet. The Tamron allows you to frame shots from far away. The Sigma captures broader scenes in tight spaces. These are opposite tools for different distances.
Maximum Aperture
Aperture controls light intake and depth of field. The Sigma 30mm has a wide f/1.4 maximum aperture. This lets in more light for low-light shooting. It also creates shallow depth of field for blurry backgrounds. The Tamron 150-500mm has a variable f/5-6.7 maximum aperture. This is much smaller. It requires more light for the same exposure. The Sigma wins for low-light performance and background separation. The Tamron is optimized for distance, not light gathering.
Size and Weight
Portability differs greatly between these two lenses. The Sigma 30mm is compact and lightweight. It measures 2.55 inches in diameter and 2.89 inches long. It weighs only 9.35 ounces. You can carry it easily all day. The Tamron 150-500mm is large and heavy. It measures 3.7 inches by 8.3 inches. It weighs six pounds. This is a substantial piece of glass. You likely need a tripod or monopod. The Sigma is far easier to carry for everyday use.
Image Stabilization
Handheld stability matters for telephoto lenses. The Tamron 150-500mm includes VC image stabilization. It helps reduce shake when shooting at 500mm. There are three modes: standard, panning, and framing priority. This makes handheld shots at long distances more possible. The Sigma 30mm data does not list image stabilization. As a prime lens, it relies on your technique or camera body stabilization. The Tamron has a clear advantage here for handheld telephoto work.
Optical Construction
Image quality depends on internal lens elements. The Tamron uses XLD, LD, and GM glass elements. These reduce color fringing and chromatic aberration. This improves clarity across the zoom range. The Sigma features nine rounded aperture blades. This affects bokeh quality, creating smoother background blur. The Sigma also uses a stepping ring motor for autofocus. The Tamron uses a VXD motor. Both aim for sharp images, but use different optical strategies to achieve their results.

Travelers prioritizing portability and weight
The Sigma 30mm lens is significantly lighter. It weighs only 9.35 ounces. The Tamron lens weighs six pounds. The Sigma measures 2.89 inches in length. This makes it easy to carry all day. You can focus on shooting without the burden of heavy gear.
