7Artisians 28mm f1.4 ASPH FE Plus is designed for Sony A7 to improve edge image quality

After the full frame mirrorless camera Sony A7 was launched, many manufacturers replaced the Leica M port lens with the E slot and sold it to Sony users. 7Artisians's new 28mm f v1.4 ASPH E + is not only as simple as replacing the slot, it adjusts the lens optical design and optimizes the edge image quality for the different microlenses of Sony and Leica sensors

Earlier, the 7Artisians introduced the 28mm f1.4 lens used by Leica M, which costs just over 3000 yuan, an order of magnitude cheaper than the original lens, and attracted a lot of consumer attention. According to the conventional operation, as long as the 7Artisians replace the card port, they can launch Sony E, or Canon RF, Nikon Z version, one mirror to sell more. The 7Artisians took a different approach to the 28mm f1.4 FE Plus, fine-tuning the optical structure, but retaining the M card lens, which makes the picture better when transferred to the Sony A7 series.

 

We know that in order to improve the edge image quality of the lens in the digital age, especially the edge image quality of the wide-angle lens, the CMOS sensor performance is covered with a layer of microlens. The Radian of Leica M microlens is higher, which can effectively improve the angle of light incident into the edge photodiode of the sensor, the edge resolution is higher and the dispersion is smaller. The Radian of Sony A7 microlens is obviously lower than that of Leica.

 

According to the different A7 microlens, the 7Artisians fine-tune the 28mm f 1.4 ASPH E + optical design, change the light wide angle incident angle, improve the image quality, and no longer collapse the edge. It is important to note that the edge image quality of 28mm f 1. 4 ASPH E + used on Leica M is lower than that of 28mm f 1. 4.
