Focal Length 20mm
The focal length of 20mm was always my favorite as it is not so wide to distort objects, and on the same time is wide enough to capture all the necesary elements in the frame.
Back at 2019 when I was looking for a new mirrorless camera after I sold the Sony A7RmkII due to its strange color science, I always kept in mind that the new camera must support this lens no matter what.
After checking online that an E to Z Mount electronic adapter will be available for the Nikon Z cameras, I decided that this was probably the perfect choice at the time, as I would be able to use this fantastic lens with the great (for my liking) colors of Nikon cameras.
And now, after 1.5 years since buying the Z6, I can honestly tell you that this combination is marvelous!
The focal length of 20mm is very versatile and super creative as with the right use, it can be used for almost every photography/videography genre like astrophotography, landscape, real estate, travel, vlogging, wedding and timelapse!
With its constant F2 aperture, and its superb sharpness across the frame even wide open, this lens is possibly one of the best lenses that I have ever used.
Now that Sony color science is improved and for sure it came more close to my personal likings, a new Sony A7 (Siii) will very soon join my FiRIN 20mm F2 AF lens as my go-to combo.
