Review: Gamechanger! The cheapest anamorphic lens - I have all of Sirui's lenses released so far, the 24mm, 35mm and this 50mm that started it all. All I can say is this was the first anamorphic lens released under £1000 which in itself is a miracle. I have always wanted to have anamorphics since I was a teen and while this is not the full 2x squeeze this is still a unique lens by itself that I still marvel at the image that comes from this . The construction is amazing like the other 2 lenses it is solid metal with no plastic excet the caps. The lens itself is extremely sharp at F1.8 all the way down the aperture and bokeh is unique. But it is the flares that pops out of this lens the 24mm has the least amount of flares but this one can give you that JJ Abrahms look. One thing with all Sirui's lenses is that the coatings are different and this is gives a colour cast that is the coolest of the bunch while the other 2 leans towards a more warm tone so just bare that in mind when matching different lenses. Overall an excellent lens to start with and has changed the anamorphic game forever as new lenses will come out not just from Sirui bit other competitors as well. Sirui have also announced new lenses coming and that it will be a longer lens then this so keep an eye out but for now this is a great lens for close ups or even unique photography.
Review: Amazing lens! - Item arrived safely and in perfect condition, exactly as described. Delivery was quick and packaging was secure—no damage at all. The quality is excellent, and the value for the price is great. Very satisfied with the overall experience. Smooth transaction, great service, and a product that’s totally worth it. Highly recommend and would definitely buy again. Thanks!

### ⭐⭐⭐⭐ 50mm is peculiar but great
*by T***N on 1 May 2026*

The 50mm version is a peculiar Lens for video, it’s easy to use and easy to focus manually, however can look a little warped sometimes but it’s important to use software to do a anamorphic De-squeeze for 1.33x and you can get some amazing professional looking results (see video on this review) I am happy with this Lens but it takes an little getting used to. I found a phone app that does the desqueeze called CineDesqueeze which was reasonable priced and gives good results. I am looking forward to filming events and fireworks with this Len’s and more nature scenes.
