Tamron 17- vs Tamron 35-

Overview of the Tamron 17-70mm f/2.8 and 35-150mm F/2-2.8 Lenses

The Tamron 17-70mm f/2.8 Di III-A VC RXD Lens for Sony E APS-C and the Tamron 35-150mm F/2-2.8 Di III VXD for Sony E-Mount offer distinct capabilities for photographers. The 17-70mm lens is priced at $599.00, making it about 60% cheaper than the 35-150mm lens, which retails for $1,499.00. Understanding their features will help you determine which lens best suits your photography needs.

Optical Performance

Both lenses boast outstanding optical performance, but they serve different purposes. The 17-70mm lens features 16 elements in 12 groups, including two GM (Glass Molded Aspherical) lens elements, which enhance its image quality across its zoom range. In contrast, the 35-150mm utilizes advanced optical engineering to deliver exceptional performance throughout its focal length, catering to both travel and portrait photography. This means if you prioritize versatility and high-quality images, both lenses deliver, but their optimal uses differ.

Focal Length and Versatility

The two lenses offer different focal length ranges that influence their versatility. The 17-70mm lens provides a 4.1x zoom ratio, covering a focal length equivalent to 25.5-105mm in full-frame terms. This range is ideal for everyday shooting. On the other hand, the 35-150mm lens covers a wider range from 35mm to 150mm, offering even greater versatility for various photography scenarios, including portraits and landscapes. If you're looking for a lens that can handle a broader range of subjects, the 35-150mm is the more flexible option.

Build Quality and Design

In terms of build quality, both lenses are designed to withstand various shooting conditions. The 17-70mm lens features moisture-resistant construction and a fluorine coating, ensuring durability in challenging environments. The 35-150mm lens also emphasizes durability with its robust design, measuring 6.2 inches in length and weighing 41.1 oz. While both lenses are built to last, the compact size and lightweight nature of the 17-70mm make it a more practical choice for travel and everyday use.

Close Focusing Capability

Close focusing capability is another area where these lenses differ. The 17-70mm lens offers a minimum object distance (MOD) of just 7.5 inches at 17mm and 15.4 inches at 70mm, making it suitable for macro-style shots. In contrast, the 35-150mm has a MOD of 13 inches at the wide end, which is still commendable but falls short of the 17-70mm's close-up abilities. If macro photography or detailed close-ups are essential to your work, the 17-70mm lens is the stronger contender.

Autofocus Mechanism

Autofocus performance is crucial for capturing fast-moving subjects. The 17-70mm lens features upgraded VC (Vibration Compensation) that works effectively with Sony APS-C mirrorless cameras, significantly improving video shooting. Meanwhile, the 35-150mm lens is equipped with a fast, quiet VXD linear motor, ensuring high-speed and precise autofocus. This makes it particularly advantageous for event and portrait photography, where timing is everything. Depending on your shooting style, either lens could excel in autofocus, but the 35-150mm may have the edge for speed.

Target Audience

The target audience for these lenses differs significantly. The 17-70mm lens is ideal for everyday photographers, especially those using APS-C cameras, who need a reliable standard zoom lens. It supports many features that Sony cameras offer, including Fast Hybrid AF and Eye AF. Conversely, the 35-150mm lens is designed for more serious photographers, such as enthusiasts and professionals, looking for a versatile lens that covers a wide range of focal lengths without the need to change lenses frequently. If you're a more casual shooter, the 17-70mm might be the better fit.

Which should you buy?

Choosing between the Tamron 17-70mm f/2.8 and the 35-150mm F/2-2.8 ultimately depends on your specific photography needs and budget. The 17-70mm lens is about 60% cheaper and offers great versatility for everyday use, making it ideal for casual and travel photographers. However, the 35-150mm lens is a powerhouse for serious enthusiasts and professionals, providing a wider focal range and superior low-light performance. If you prioritize versatility and can invest more, the 35-150mm is a fantastic choice. Conversely, for those seeking a reliable, high-quality zoom lens without breaking the bank, the 17-70mm is hard to beat.
