Tamron 17-50mm f/4 VC Patent Found

By Louis Ferreira | Published: July 4, 2023


A patent for a full-frame Tamron 17-50mm f/4 VC lens was found on IP Force.

  • Applicant: Tamron Co., Ltd.
    Publication number: P2023092730
    Application number: P 2021207918
    Publication date: 2023-07-04Title
    of invention: Optical system and imaging device
  • Kind Code: A1 A zoom lens and an imaging device are provided which are compact and lightweight and have high imaging performance over the entire zoom range.
  • There is a demand for a high-resolution, compact zoom lens capable of covering a wide imaging angle of view. Further, in such a zoom lens, realization of high-speed and high-precision autofocus is also required.
  • If the angle of view fluctuates greatly due to wobbling, a sense of discomfort may occur in the captured image or the like. In order to alleviate this discomfort, it is conceivable to use the lens group behind the diaphragm as the focus lens group. Further miniaturization and weight reduction of the focus lens group are desired in order to drive the focus group continuously at high speed during moving image pickup.
  • Patent Document 1 proposes a wide-angle zoom lens consisting of six groups of negative, positive, negative, positive, negative, and positive, with the fifth lens group being the focus lens group, but the size and weight of the focus lens group are also insufficient. .
  • SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a zoom lens and an imaging apparatus that are compact and lightweight and have high imaging performance over the entire zoom range.
  • Example 1 (17-50mm F4) Zoom ratio 2.767
    Focal length 17.520 29.114 48.483
    F number 4.120 4.120 4.120
    Angle of view 110.747 71.937 47.366 Image
    height 21.633 21.633 21.633
    Optical length 134.4 56 133.533 134.456
    Back focus 18.462 27.816 50.815
  • Even when the zoom lens is provided with an anti-vibration function, it is possible to keep the zoom lens compact and lightweight while maintaining good imaging performance during anti-vibration.

OL: Sony FE 100-400mm f/4.5-5.6 GM OSS Review

By Louis Ferreira | Published: June 30, 2023


The Sony FE 100-400mm f/4.5-5.6 GM OSS has been around for a while and Optical Limits just published their full review of the lens here. Below is an excerpt from the review:

The Sony FE 100-400mm f/4.5-5.6 GM OSS delivered decent, albeit not exceptional results during our testing. At 100mm, it is certainly very sharp. There’s a slight, continuous downturn in quality the more you zoom out. The image center is still very good to excellent at 400mm, whereas the outer image field softens somewhat more. Lateral CAs are relatively low, but they are auto-corrected anyway. The same applies to image distortions. RAW images reveal some vignetting at wide-open aperture, but, once again, that’s mostly hidden from you as an end user. A positive aspect is the quality of the bokeh. Some may frown upon the slow max aperture, but the technical out-of-focus rendering is much better than usual for a long tele zoom lens.

In terms of build quality, the lens remains true to its GM designation – meaning that it is aligned to professional use. The metal construction feels tough and the dust- and moisture-sealing makes it suitable for more difficult outdoor conditions. The extending zoom mechanism may not be ideal, but it allows for a compact size during transport. The AF speed is very high. The image stabilizer is pretty efficient as well. A specialty of the lens is its close-focus capability. The Sony lens features a floating focusing system that optimizes the optics according to the focus distance. While this doesn’t put it into the same league as a dedicated macro lens, you can expect better results than from most other lenses in its class here.
