PP: Sony a7RV vs Nikon Z8 – Spoiler Sony Wins

Chirs and Jordan compared the Sony a7RV and Nikon Z8 in the lengthy comparison above. While the Nikon Z8 is a great camera the Sony a7RV is just that much better so it is the clear winner for most photographers. From AF to Lens Selection to Ergonomics to Image Quality, Sony wins hands down for photography. So what does Nikon win? Burst Shooting, Video, and according to Jordan the Nikon Z8 is one of the best video cameras ever made.

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


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.

Sigma 50-140mm F/2.8 DC DN and Sigma 70-200mm f/2.8 DG DN Patents Found


overview

  • [Publication number] P2023090116
  • [Release date] 2023-06-29
  • [Title of Invention] Imaging Optical System
  • [Application date] 2021-12-17
  • [Applicant]
    [Identification number] 000131326
    [Name] Sigma Corporation
  • Kind Code: A1 A compact image forming optical system having a small open F value over the entire zoom range is provided.
  • 2. Description of the Related Art
    In recent years, a so-called mirrorless camera, which eliminates a quick-return mirror that is arranged between an imaging optical system and an imaging device and guides light rays to a finder optical system, has become popular. Since the body of the mirrorless camera has been downsized by eliminating the mirror, downsizing of the imaging optical system is required accordingly. Also, there is a demand for a large aperture zoom lens with a small open F-number over the entire zoom range.
  • [0004]
    Patent Document 1 discloses a positive lead type zoom lens having a bright open F number of about 2.8 and having a lens group closest to the object side fixed with respect to an image plane during zooming. Since the optical total length does not change, convenience and robustness are high, but there is a problem that the size of the imaging optical system is large. Patent Document 2 discloses a positive lead type zoom lens having a bright open F number of about 2.8 and a shortened total optical length at the wide-angle end. However, since many lens groups with large diameters that move during zooming are arranged on the image side of the aperture stop, the mechanism required for zooming is large, and the size of the lens barrel in the radial direction is large. .
  • SUMMARY OF THE INVENTION It is an object of the present invention to provide a compact image forming optical system with a small open F value over the entire zoom range .


Example 1

  • Focal length: 50.50-136.50
  • F-value: 2.92
  • Half angle of view: 30.62-11.40
  • Image height: 14.20
  • Total length: 125.00-145.00


Example 2

  • Focal length: 72.00-194.10
  • F-value: 2.92
  • Half angle of view: 32.92-12.12
  • Image height: 21.63
  • Total length: 168.00-203.60
