What does PZD mean on Tamron lens?

The “PZD” designation in the name refers to Tamron’s “Piezo Drive”. What it is, is an auto focus drive that uses a small piezoelectric motor (or ultrasonic) to control the focusing mechanism with a gear system.

What does Di VC USD mean?

The SP 24-70mm F/2.8 Di VC USD is one of Tamron’s Di (Digitally Integrated) designs. The Di Series is the mark of Tamron lenses that are format-versatile since they can be used on digital APS-C, full-frame and 35mm SLR cameras.

What is USD on Tamron lens?

USD – Ultrasonic Silent Drive. This is a silent motor for auto-focusing. VC – Vibration Compensation. This is the stabilization, allowing you to handhold the camera while reducing camera shake.

What is DI on Tamron lens?

Di (Digitally Integrated Design) lenses are designed for full-frame and APS-C format digital SLR cameras and feature an optical design tailored to the characteristics of digital cameras.

Which lens is better Sigma or Tamron?

The results for both the Tamron and Sigma models are very similar, with the Sigma only very slightly better than the Tamron over the entire focal range. Of greater note is that both lenses are exceptionally good when compared to the Nikon 17-55mm and the Canon 17-55mm f/2.8, which are twice as expensive!

What Does VC mean on a camera lens?

This lens is equipped with a tri-axial image stabilizer called vibration Compensation (VC), a Tamron proprietary development. The VC feature minimizes the effects of camera vibrations and shake of hand-held photography.

Where are Tamron lenses made?

In other words, Tamron has lens-producing plants in the three countries of Japan, China and Vietnam, which assemble and ship the products. In Japan, Tamron’s main plants are situated in three locations in Aomori Prefecture.

What does G2 mean on Tamron lens?

The ‘G2’ stands for second generation, reflecting several improvements to the design. These improvements include more effective image stabilization (to a claimed 4.5 stops of benefit), faster AF speed and compatibility with Tamron’s ‘TAP-in’ Console, for lens firmware updates and customization.

What does Tamron Di II mean?

A Tamron “Di” (Digitally Integrated) lens is a lens optimized for digital cameras including those with 36x24mm ‘full frame’ sensors. A Tamron “Di II” (Digitally Integrated II) lens is a lens optimized for digital cameras with an APS-C sized sensor.

What is Tamron 18-270mm PZD?

The acclaimed Tamron 18-270mm VC ultra zoom for APS-C format DSLRs has reached an astonishing new level of compactness, performance, and speed with the addition of PZD (Piezo Drive), an innovative ultrasonic autofocus motor based on an advanced piezoelectric design.

Is the Tamron 18-270mm a Pentax-fit lens?

Tamron doesn’t make a Pentax-fit model, but the recently-announced Pentax smc DA 18-270mm F3.5-6.3 ED SDM is in all probability essentially the same lens, again without the VC module. The Tamron 18-270mm’s closest competitor is the Sigma 18-250mm f/3.5-5.6 DC Macro OS HSM, a very similarly spec’ed lens that we reviewed recently.

Why Tamron aspherical lenses?

Tamron uses several hybrid Aspherical lens elements in many lenses bearing the Aspherical designation. These innovative optics allow us to achieve the ultimate in image quality, and at the same time produce lenses that offer remarkable zoom ranges in extraordinarily compact packages.

What is a 270mm lens used for?

These lenses are not designed for conventional cameras and digital cameras with image sensors larger than 24mm x 16mm. This lens covers an extremely broad range of focal lengths, from an extra-wide 18mm length to a telephoto 270mm length (the 35mm equivalent of 28mm to 419mm).
