  • Excellent anamorphic lens
Size: L Mount
My background: I’ve been a full time commercial stills photographer and director of photography for almost 20 years and am used to working with really high end lenses and camera systems. That being said I had low expectations for a lens at this price point. My expectations were exceeded. I’m pretty impressed with this lens. It’s sharp in the perfect ‘cinema lens not too sharp’ kind of way. It’s well built and the focus and aperture rings are silky smooth and perfectly dampened. The color rendition and contrast are pleasant and natural. The flare control is well corrected and when it does flare it’s got that nice anamorphic look that isn’t overkill. I have zero issues with this lens. It’s so nice for the price that I’ll likely pick up the 35mm and 75mm versions. My only gripe is I received a previously returned item that had been opened and used. Packaging was cut open with scissors and lens cap was all scuffed up. I did not order a used lens. Since the lens itself is mint and in perfect working order I didn’t bother to send it back for exchange. ... show more

  • Amazing
Size: E Mount
I was debating to either grab the smaller Saturn version for my FX3 or to go with this Venus version for a few bucks more. Man, I am happy with this lens. Compared it to my buddies Saturn version and the Saturn feels a tad bit sharper but more soap opera looking. This Venus version makes literally every, and I mean every, scene and thing I filmed, look like a dang movie. It's amazing. Shipping wise I wish Amazon would have at least padded the smaller box in the bigger box they send it in. Sirui on the other hand did a terrific job padding this bad boy. They even vacuum sealed this bad boy and it was super gratifying opening this package. The lens performance is astonishing, nice and smooth towards the edging, amazing low light performance and silky oval bokeh. Even in broad daylight the T stops allow to film in very bright conditions without killing the subjects details too much, of course a mat box with ND Filters will be better, but for what it does, its amazing. Focal Ring and T Ring are tight and smooth. I am running this on my RS3 with the lidar for follow focus and it's amazing how it keeps focus with the subject. All in all, I love that I bought this lens. Future Videos will be uploaded on my YT channel. You can find my under 808statehawaii (808-Stat3) . ... show more

  • May The Force Be With You... Prepare for amazing Bokeh, and Light Flares
Size: RF Mount
Sirui has done an amazing job creating this budget-friendly anamorphic lens. The heavy metal build quality, creamy bokeh, and flares that hit just right and are not overdone make this lens a go-to in my kit. The consistent gearing across the range is super helpful as I am always able to leave my follow focus in place. To top it all off it's at a price point you can't beat. If you are looking for a great anamorphic lens at a great price, it is definitely worth a shot. ... show more

  • Surprisingly soft.
Size: E Mount
Surprisingly soft. I experienced a situation that was unlike normal sirui products; my image quality was muddy and soft. I run a Sony fx3, a9iii, and a7rv, so I was truly able to test its sharpness across multiple specialities. I look forward to using other sirui products, but this one was unfortunate. ... show more
