Sirui’s 35mm full-frame anamorphic lens is a really attention-grabbing piece of kit. Whereas anamorphic lenses have been as soon as the area of cinema lenses, Sirui’s Venus sequence blurs the road between cinema and nonetheless images, partly because of the massive choice of suitable mounts. Is it price utilizing an anamorphic in your mirrorless digital camera? How can the Sirui 35mm t/2.9 maintain as much as 45 megapixels and 8K footage? That is what I’ll cowl on this assessment.
Why Anamorphic?
Crucial factor to know when contemplating an anamorphic lens, for nonetheless or video seize, is that there are inherent tradeoffs in lens design. I’ve written a whole information to what anamorphic lenses can do, however the important thing level is that anamorphic lenses have a “compression issue”. They permit you to seize pictures with a special facet ratio from the digital camera sensor itself.
On the Sirui 35mm t/2.8 (and on all lenses within the Venus vary), the compression issue is 1.6x. After decompressing the photograph in post-production, your pictures and movies could have extra of a panoramic facet ratio. For instance, with a regular full-frame sensor with a facet ratio of three:2, your decompressed pictures could have a facet ratio of two.4:1. (In the meantime, capturing 16:9 video offers you a 2.8:1 facet ratio.) It additionally means this lens captures a wider horizontal discipline of view than a typical 35mm lens, as for those who had a 22mm lens as a substitute.
Anamorphic lenses subsequently have nice benefits. For one factor, lenses permit you to seize distinctive facet ratios with out cropping the shot, retaining extra of your pixels, each in stills and videography. Past that, anamorphic lenses have distinctive bokeh and flare results that look very cinematic. Lastly, they’re simply plain enjoyable to make use of for those who’re used to conventional lenses and might increase your creativity.

It may be troublesome to find out the place all the things will likely be in your closing composition. Some exterior screens assist shrinking this view, however in any other case it is a matter of apply.
One other drawback with anamorphic lenses is that you must take the time to decompress your pictures or movies afterwards. It is simple in Photoshop and nearly any video editor, however it does add a bit of labor earlier than you’ll be able to see your footage correctly.
Lastly, for picture high quality, anamorphic lenses have distinctive traits equivalent to totally different reflections and bokeh. These traits are sometimes fascinating for video work, however they aren’t for everybody. By way of sharpness, the 35mm Sirui delivers wonderful outcomes, in order that’s not likely a problem.

This impression is additional confirmed by the truth that the main focus and aperture marks are all on the edges of the lens!

Optical traits
Whereas at first look a 35mm t/2.9 won’t seem to be a very troublesome optic to design, that modifications when you make it anamorphic and get picture high quality excessive sufficient to make use of on an 8K digital camera. Fortunately, Sirui rose to the problem, and the 35mm delivers wonderful ends in each stills and high-res video.
The middle of the body may be very sharp, resolving loads of element on a 45MP physique, with surprisingly few aberration points. Sharpness is nice extensive open, however stopping at f/5.6 brings a bit extra chunk to the middle of the body. Outcomes from the center of the body are good even extensive open, whereas solely the acute corners are a bit softer.
It is laborious to guage pattern variation from a single lens, however my copy was centered fairly effectively. The highest proper nook was barely decrease than the opposite corners, however it did not rise to the extent of being a problem. Provided that uncompressed photographs from a 45MP sensor push over 65MP, it is necessary that the lens performs effectively, and the Sirui 35mm T2.9 definitely does.
Not like many lenses, customers of anamorphic lenses are sometimes for flares fairly than attempting to keep away from them! Many anamorphic lenses promote their particular coloration vibrancy as a advertising and marketing characteristic. The Sirui Venus 35mm T2.9 has blue flares, which aren’t troublesome to impress, however not often turn into overwhelming. Even capturing in vivid daylight and emphasizing shadows produced solely a slight lack of sharpness, which is near the perfect end result for an anamorphic lens.
Though the Sirui Venus 35mm T2.9 will not be absolutely optimized for photo voltaic stars, the 10-blade aperture can nonetheless produce stunning 10-point stars round gentle sources. Together with the anamorphic flares, this positively makes the footage look strongly cinematic proper out of the digital camera. Shutting down actually causes these solar stars, nearly to a distracting extent – for those who’re working with a variety of level gentle sources, limiting your aperture to f/5.6 or larger can hold the look extra understated.
General, the optical efficiency is sort of good for this lens. Protecting a full-frame picture circle with an anamorphic look, whereas nonetheless with the ability to monitor 45MP stills and 8K video, is spectacular. Whether or not you take pictures or movies, this lens will not damage your picture high quality.

Cinema-quality anamorphs can value as a lot as a brand new automotive, so a price ticket of round $1,500 is a game-changer for smaller productions. I’d extremely advocate this lens to any videographer on a funds who needs the traits of an anamorphic lens.
For nonetheless photographers, this can be a much less apparent worth. From the physique design to the scale and usefulness, this lens is meant for cinematic use, though it additionally works very effectively for stills images. The anamorphic look is unquestionably underexplored for nonetheless images, and it provides a singular really feel harking back to XPan movie footage. Should you’re in search of one thing new to attempt, it would nonetheless be price a shot, however I would not advocate photographers purchase it on a whim. At $1500, that is positively not a elaborate/enjoyable Holga lens.
