Review: إذا كنت من محبين التصوير السينمائي فالعدسة دي لك تركيبها سهل و وزنها خفيف وصورتها في التصوير رائعة
Review: 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.
