   To be honest, the 75mm focal length as a portrait lens is actually a relatively small existence in the field of full-frame. Among the mainstream digital imaging manufacturers we are familiar with, 85mm is the standard focal length of the portrait lens. But in fact, users who have experienced the digital partial-frame era should be familiar with this focal length. In the early APS-C era, 50mm fixed focal length lenses were often used as portrait lenses and the equivalent focal length was exactly 75mm. In other words, this focal length is actually the most familiar stranger.

   The Seven Craftsman 75mm/F1.25 lens we are talking about today It is a Leica M mount lens. In fact, 75mm is not an unfamiliar focal length in Leica M series cameras. There are currently three original lenses in service, SUMMARIT-M75mm/f2.4, APO-Summicron-M 75mm f/2.0ASPH, and NOCTILUX-M 75mm f/1.25 ASPH.

   In addition to the choice of the original factory, I have been serving Leica for a long time Voigtlander also has a similar focal length-NOKTON Vintage Line 75mm F1.5 VM and VM 75 1.8 Voigtlander 75mm F/1.8. But in comparison, the Seven Craftsman 75mm/F1.25 is the most cost-effective for less than three thousand yuan. Of course, many users buy this lens not for M-series cameras, but more likely to consider full-frame mirrorless cameras such as Sony, Nikon, Canon and Panasonic. In my actual experience, I do feel that perhaps this kind of full-frame mirrorless camera with more convenient electronic focusing performance would be more suitable for this large aperture portrait lens.

   From the overall appearance, this 75mm/ The 1.25 lens weighs 600g, and the all-metal lens body material gives people a solid and dropped feeling. The excessive sharpness of the aperture dial and the damping effect of the focus ring are also obvious. Overall, the workmanship of this lens infinitely close to Leica style is satisfactory. It is undeniable that with the continuous improvement of domestic manufacturing processes, the texture of the lens appearance is commendable, and what is needed in the future may be the stage from Chinese manufacturing to Chinese creation.

   Finally, I will summarize the experience of this lens, the workmanship of the lens All can be ordered. The blurring ability brought by F1.25mm aperture is what many portrait photographers need. The resolution is the relatively weak point of this lens, and there is also a relatively obvious purple fringing. But considering the market price of less than three thousand yuan. Obviously, we shouldn’t make a comparison with tens of thousands of original factory lenses. From my personal experience, this lens is more fun and malleable. For M users, you can experience the fun of portrait shooting at 75mm focal length and consider whether you are at this focal length. For non-M users, you can buy a cost-effective lens and install it on your own full-frame mirrorless lens of about 10,000 yuan to experience the blur and low-light shooting capabilities brought by a large aperture. It was mentioned earlier that this lens is actually more suitable for Japanese full-frame mirrorless cameras with more advanced electronic analog focus. After all, due to the lens focal length and aperture, the accuracy of this lens in the M series macular focus is not high. The digital peak focus is relatively speaking, this lens is more suitable for this lens focusing method.
