Vintage glass is enjoying great popularity among filmmakers - those who find the high-resolution digital image too sharp can achieve a softer look with older lenses. Some manufacturers are even releasing current lenses in retro versions, with different coatings for less optimized light scattering. ;) Petzval lenses with focus-coupled bokeh control Many years ago, the Lomographic Society discovered and reissued a very special lens - the Petzval with its typical swirl bokeh. Now it appears in a newly calculated series, designed especially for video recording. The "Joseph Petzval Focus-coupled Bokeh Control Art Lens Series" is a handmade series of cine-style lenses (35 mm f/2, 55 mm f/1.7 and 80.5 mm f/1.9) for full-frame mirrorless cameras (E / RF / Z), which, as a special innovation compared to the Petzvals released so far, brings a mechanical coupling of focus and bokeh control.
;) While the special bokeh adjustment ring, with which the aesthetics of the image can be changed in 7 steps during filming, already existed on some lenses, here the focus should no longer shift when the bokeh ring is turned. (We haven&t been able to find out exactly what happens in the lens when the bokeh ring is turned to change the strength of the distortion; the aperture obviously doesn&t change.) If, on the other hand, the focus is shifted during a recording, the coupling should make the wandering of the depth of field behave more naturally than before; although "natural" may not be the right word here. With 180° focus travel, follow-focus compatibility (MOD 0.8), standardized ring spacing, and de-clicked aperture, the new Petzvals also offer video-friendly features. The Petzval lens is considered the first portrait lens in the history of photography; it was designed by Josef Maximilian Petzval in Austria in 1840 and initially manufactured by Voigtländer. It was calculated - a novelty at the time - on the basis of optical laws and was brighter than previous lenses. It enabled portraits with exposure times of less than a minute for the first time (which makes you smile today, but was a sensation at the time). A characteristic of the Petzval lens, however, is also a strong drop in sharpness at the edges of the image; what later lens designs (successfully) sought to correct is now the typical, sometimes sought-after look. Price and availabilityThe new Joseph Petzval Focus-Coupled Art Lenses series from Lomography will include a total of five focal lengths and will be available for Sony E, Canon RF and Nikon Z cameras. The 35 mm f/2, 55 mm f/1.7 and 80.5 mm f/1.9 are available for order now, while the 27 mm and 135 mm are still in development. Individually they should cost 499 euros, the 3-piece set costs 1,272 euros. Bild zur Newsmeldung:
