Tamron: "35-150mm F/2-2.8 DI III VXD (Model A058)" [CP+2022 Exhibition Report] -PRONEWS: Digital video production Web magazine

Achieved open F2 at the wide -angle end.A portrait zoom lens "35-150mm F/2-2-2-2-2-2-2-2-2-2" that covers 150mm in telephoto from a quasi wide-angle 35mm.8 DI III VXD (Model A058) "

We talked to Tamron staff about the products scheduled to be exhibited at the CP + 2022 online and the real exhibition hall.

――Please tell us about the highlights of CP + 2022 (product/service/solution).8 DI III VXD (Model A058) for Sony e -mount.

―― Please tell me the main features and appeal points are the following four main features.

（1）Eマウントレンズとして世界初^※のF2-2.8 ( * In the Sony e -mount zoom lens for full -size mirrorless, Tamron as of August 2021) (2) High image quality, high -resolution (zoom ratio 4).Realizes high optical performance in 3 times

(3) Equipped with a linear motor focus mechanism VXD (VOICE-COILEXTREME-TORQUE DRIVE) that realizes high-speed and high-precision AF (4) new lens design.By reviewing each part that makes up the lens in detail, the texture is improved along with the operability (28-75mm F2).8 G2 (Model A063) Zoom ring focus ring is added to the inside to achieve more smooth operability.Realizes a grip that fits your hand with a sharp lens body.Adoption of new paint that is less noticeable in scratches and fingerprints

――What kind of sites and scenes do you recommend or assume?It is ideal for portrait shooting, mainly 85mm in medium telephoto, from shooting the whole body, including the surrounding scenery, to shooting a bust -up that emphasizes facial expressions and gaze at 150mm.Especially in portrait shooting, which is particularly important for rhythm, the advantage is that you can shoot seamlessly without lens replacement, and it is possible to create works that do not miss the instant expression of the model.

―― Please tell me the development concept of the product. Full size Mirrorless SLR compatible Sony E -mount Zoom lens for the first time open F2 at the wide -angle end, high -resolution portrait zoom that covers from semi -wide -angle 35mm to 150mm telephoto.Lens.It can cover the whole body, bust -up of the person who is the subject, and a photo of the expression, etc., without lens replacement, and achieves a clear depiction that makes the subject stand out in the whole zoom and a soft bokeh.Furthermore, by renewing the lens design, the grip and operability are greatly improved.

――Please tell us about the difficulties that you struggled during planning and development, the points you were particular about, etc. In the optical performance, the F value in the original product plan is 2..It was eight, but F2.35-150mm F2-2, because it is possible to shoot in a darker environment that cannot be expressed in 8, and that it can be stored in the current size even at the beginning of F2..It will be commercialized with the specifications of 8.Since it is a portrait zoom lens at the beginning of F2, we took a lot of time about blur taste.In particular, the number of aspherical lenses is reduced as much as possible in order to prevent the rings of the rinseed lens (the phenomenon in which a muddy pattern appears in the bokeh statue).By reducing the non -spherical lens, the number of lenses increases, but by reducing the mechanical parts, it is included in the current product size.In order to maintain high optical performance, I had a hard time in the design.The total weight of one lens frame on one lens frame is larger than the previous model, and the design of the lens holding structure is much elaborate.In addition, F2.The zoom ratio, which is brighter than 8 and is the largest class in the entire zoom.In order to achieve high optical performance like a single focus in three times, instead of simply increasing the number of lenses and the moving lens, the design that secures the performance in the product and designs the "manufacturing error" as much as possible. doing.

In addition, the operation feeling has been improved.The major impact on the operability of the zoom is how to set the largest and heavy first group zoom movement.This lens configuration uses a configuration that can reduce the amount of movement of this first group, contributing to the smoothing of zoom torque.At the same time, in order to achieve overall rigidity and smooth operation, the metal member used is minimal and the weight is reduced to the minimum.
