Optical limits published its full review of the Sony FE 24-70mm f/2.8 GM II which you can read in full here. It sounds like Sony really stepped up the quality of Sony’s new 24-70mm GM lens in addition to lightening the lens quite a bit. Below is an excerpt from the review.

The Sony FE 24-70mm f/2.8 GM II is a positive surprise in this lens class… At less than 700g, it is in the same weight class as your average 24-105mm f/4… great sharpness at most settings. The results are just great at 24mm and 40mm and still quite impressive at 70mm. The vignetting, distortion and CA figures are about typical for a lens in this class… The quality of the bokeh is pretty good for a standard zoom lens – especially when compared to its predecessor. In critical scenes, you may spot some LoCAs but it isn’t overly pronounced at least. The weakest aspect of the Sony lens is flare which can get freaky in difficult scenes thus it’s also a good idea to leave the lens hood attached during shooting.

…Despite using more plastics, the Sony FE 24-70mm f/2.8 GM II still feels like a professional-grade tool… lens is sealed against dust and moisture – and the fluorine-coated front element should help in this respect as well. …Sony has been using XD linear motors for focusing for a while now but this time they incorporated no less than 4 of them …the AF speed is exceedingly fast and, of course, silent. In-lens image stabilization is not provided…

Overall, the Sony FE 24-70mm f/2.8 GM II is an impressive piece of equipment and at least for the time being, it’s back at the top of the food chain. Highly recommended!

Tamron 90mm f/2.8, 60mm f/2 APS-C, 180mm f/3.5, and 150mm f/2.8 Patents Found

By Louis Ferreira | Published: June 21, 2022


Overview

  • [Public number] P2022092339
  • [Release date] 2022-06-22
  • Description: Optical system and image pickup device
  • [Filing date] 2020-12-10
  • [Applicant]
    [Identification number] 000133227
    [Name or name] Tamron Co. , Ltd.
  • PROBLEM TO BE SOLVED: To provide a compact optical system and an image pickup apparatus having high optical performance regardless of an object distance while realizing high-speed focusing.
  • [0002]
    In recent years, small image pickup devices using solid-state image pickup elements such as digital still cameras have become remarkably widespread. Along with this, there is a demand for higher performance and smaller optical systems. In addition, it is possible to suppress aberration fluctuations during focusing, especially deterioration of spherical aberration and curvature of field during focusing from an infinity object to a short-distance object, and maintain high optical performance regardless of the object distance. It has been demanded.
  • [0003]
    For example, in Patent Document 1, the first lens group having a positive refractive power, the second lens group having a negative refractive power, and the positive refractive power arranged in order from the object side are described in Patent Document 1. It consists of a third lens group, a fourth lens group having a positive refractive power, a fifth lens group having a negative refractive power, and a sixth lens group having a positive refractive power. An optical system that focuses by moving the fourth lens group to the object side with different trajectories has been proposed.
  • [0005]
    That is, in the optical system of Patent Document 1, a focusing method based on an inner focus method having a so-called floating mechanism is adopted. The optical system disclosed in Patent Document 1 realizes high-speed focusing and suppresses aberration fluctuations during focusing to obtain high optical performance. However, the diameter of each focusing group is relatively large, and the product The overall miniaturization is not enough.
  • [0006]
    Therefore, an object of the present invention is to provide a compact optical system and an image pickup apparatus having high optical performance regardless of an object distance while realizing high-speed focusing.


Example 1

  • Focal length: 87.300
  • F value: 2.8840
  • Half angle of view: 13.4377

New Profoto Connect Pro For Sony

By Louis Ferreira | Published: June 21, 2022


Profoto announced a new Connect Pro for Canon, Nikon, Sony, Leica, and Fujifilm cameras. The new Profoto Connect Pro is marketed as being more than just a remote trigger – “it’s the central nervous system of the shoot – because everything flows through it“.

Profoto Connect Pro: B&H Photo / Adorama

Features:

  • Intuitive interface on a large display
  • Connect it via your camera’s hot-shoe
  • 100 available channels with six groups for each channel (three groups are for TTL usage, whereas the other three are for manual use)
  • Extended battery life and rechargeable batteries
  • Seamless firmware updates via Profoto AirX
  • Control all groups from the Profoto Control app on your iPad, iPhone, Android smartphone
  • Switch from TTL Mode to Manual Mode with the automated TTL settings intact
  • Sync and remote control 0.5-100 m (1.5-330 ft)
  • Price: $399

Press release:
Profoto Connect Pro – Trigger ultimate connectivity
When you’re on set, shooting off-camera with multiple lights, you need more than just a reliable trigger – you need complete control. It’s why we created the Profoto Connect Pro; it’s more than a remote – it’s the central nervous system of the shoot – because everything flows through it.

The Profoto Connect Pro is remarkably easy to use. Forget the user manual; the large display is intuitive and straightforward, with improved TTL group control. Simply slide it on your camera’s hot-shoe – and you’re ready to create great images.

Yes, in the first instance, it connects your camera with multiple flashes – but beyond that, it allows instant and complete control of each individual flash setting from your shooting position so you can finesse and fine-tune at will.

This ‘over abundance’ of control is thanks to Profoto’s awarded AirX connectivity, which allows you to tailor your workflow to whatever shooting situation you find yourself in.

You can also choose where you receive the information because the group controls on the Connect Pro are easily mirrored in the Profoto Control app on your iPad, iPhone, or Android smartphone. And with up to 100 available channels, there will always be a free channel for your lighting setup, even in the largest commercial studios.

Add to that improved battery life and seamless firmware updates via Profoto AirX, and you have a remote that takes connectivity to new heights.

“Our overarching mission is to make access to great light easy for all professional photographers. And with the introduction of Connect Pro, we take yet another step towards accomplishing our mission,” says Marko Pirc, Product Manager at Profoto.
“The Connect Pro and AirX will be at the very heart of the Profoto system, the keys to the kingdom, so to speak. And our plans for the system don’t stop here. We have great plans for it to grow and develop for years to come.”

Of course, with the Connect Pro, you’ll benefit from Profoto’s typically impeccable build quality alongside minimal and stylish design. And as you’d expect from a Profoto product, it’s utterly reliable, delivering superior consistency flash after flash – so you’ll never miss a shot.

TechArt LM-EA9 For Leica M Mount Lenses is Being Teased

By Louis Ferreira | Published: June 20, 2022

The TechArt LM-EA7 is one of my favorite AF adapters for M-mount lenses on Sony and it is finally being updated with the TechArt LM-EA9. The TechArt LM-EA7 also went by TechArt Pro, and it was compatible with just about all M-mount lenses. It looks like the TechArt LM-EA9 is a bit more compact, which should help it adapt more M-mount glass.

DXO: Yongnuo FE 85mm f/1.8 DF DSM Review

By Louis Ferreira | Published: June 20, 2022


The Yongnuo FE 85mm f/1.8 DF DSM has been out for a while, but DXO just published a review of the lense and it is super sharp. You can read the full review here or check out the summary below:

…the Yongnuo YN 85mm F1.8 S DF DSM get excellent sharpness at the center of the frame but will have to make some compromises, especially in terms of corner softness and chromatic aberrations. Build quality and materials are also not quite on the same level as the comparison lenses from Sony and Zeiss but essentially the Yongnuo offers a high level of quality at a fraction of the price of its competitors…
