By Louis Ferreira | Published: July 27, 2024


The Viltrox AF40mm f/2.5 FE has finally shown up on B&H Photo.

A compact prime lens designed for Sony E-mount mirrorless cameras, the Viltrox AF 40mm f/2.5 E Lens pairs a unique focal length with a fairly bright aperture. The incorporated STM stepping motor allows for quick and quiet autofocusing performance. This lightweight lens is ideal for everyday photography and is viable for portraiture as well. The optical design includes multiple high-quality lens elements to reduce optical aberrations and improve overall image quality.

  • One ED element, one aspherical element, and three HR elements contribute to improved image clarity and reduced optical aberations
  • Ten lens elements in six groups
  • Supports Exif data transmission
  • Minimum focusing distance: 1.1′
  • 52mm filter thread
  • Seven-bladed aperture

Viltrox Lenses can be found at B&H Photo and Amazon

Tamron BIG ZOOM Patents Found

By Louis Ferreira | Published: July 26, 2024


A few days ago we shared a rumor of an upcoming big Tamron zoom lens and now we have some leaked patents that may be related.

Tamron 400-1000mm F10-11.5 and 250-700mm F6.5-13 Patents

overview

  • [Publication number] P2024100570
  • [Release date] 2024-07-26
  • [Name of invention] Zoom lens and imaging device
  • [Application date] 2023-01-16
  • [Applicant]
    [Identification number] 000133227
    [Name or company name] Tamron Co., Ltd.
  • [Background Art]
    [0002]
    In recent years, imaging devices using solid-state imaging elements such as digital still cameras have become widespread. Accordingly, the focal length of optical systems has become longer, and so-called telephoto zoom lenses or imaging device systems including telephoto zoom lenses, which have a focal length of more than 80 mm in 35 mm equivalent, have rapidly become widespread. Lenses that are small and lightweight while maintaining high resolution by having a diffractive optical element (hereinafter also referred to as “DOE”) in the zoom range of the zoom lens have been considered.
  • [0007]
    However, in the zoom lens described in Patent Document 1, the weight of the first lens group is large, and weight reduction is required. In addition, the zoom lens described in Patent Document 1 has a problem that the balance with the weight on the image side is poor, and image shaking such as hand shake is likely to occur when shooting on the telephoto side. In addition, in the zoom lens described in Patent Document 2, although the DOE is arranged on the image side in the first lens group, the first lens group is very thin, and the diffractive surface of the DOE is located at a position close to the lens surface of the first lens group closest to the object side with respect to the total optical length. In the zoom lens described in Patent Document 3, the diffractive surface of the DOE is arranged on the object side in the first lens group. Therefore, the zoom lens described in Patent Document 2 and the optical system described in Patent Document 3 have a problem that measures against stray light flare are insufficient.
  • An object
    of one aspect of the present invention is to provide a zoom lens and an imaging apparatus that are small, lightweight, and have high optical performance with reduced stray light flare.


Example 1

  • Focal length: 411.754-970.006
  • F value: 10.342-11.490
  • Half angle of view: 2.925-1.243
  • Image height: 21.633


Example 3

  • Focal length: 250.000-710.730
  • F-score: 6.579-12.917
  • Half angle of view: 4.992-1.738
  • Image height: 21.633

Unconfirmed Sony a7V Rumor

By Louis Ferreira | Published: July 24, 2024


Photorumors received a plausible Sony a7V rumor from a reader:

  • The build quality of the parts has been significantly improved, including a great EVF, the same grip as the , and the same screen as the .
  • The biggest surprise is the 42MP back-illuminated sensor, which bumps the pixel count up to the level of the . It doesn’t have the same number of focus points as the , but it appears to be a brand-new sensor that still uses a low-pass filter. Test shots with the show very little false color in the image, which is not consistent with the test results of the lens on the . This is due to the low-pass filter.
  • The new software’s AI focus detection is more accurate and also allows high frame rate AE/AF, more sensitive to moving objects, and you can feel that the focus performance is better than the and ZV-E1, but still not as good as the .
  • The high ISO performance is more in line with the , very strong and significantly better than the .
  • No improvement in continuous shooting. Sony has stagnated in this area for too long. The electronic shutter doesn’t slow down continuous shooting, and the readout speeds are similar to those of full-frame video, but the electronic shutter is limited to 12-bit RAW and offers flash sync at 1/40s (FF), 1/60s (APS-C).
  • Unfortunately for the vast majority of videographers, the A7 V uses a higher resolution sensor and shares the video cropping modes of the , with only the differences: 4K/60p is supported in Super 35mm mode, 4K/60p full-frame crop mode and 4K/30p full frame mod are oversampled, and there is no crop for 8K video recording.
  • The new A7 V camera has a completely different logic to the , , and , with no pixel merging and no line-skipping sampling for 4K video. There is no crop-free full-frame 4K/60p.
  • The dynamic video range is by far the best on the Sony Alpha, and it is very close to the Sony BURANO’s noise level in XAVC.

Sometimes details like these leak very early so we will see.
