    • Well made and useful
Style: X-mount
Very well made lens. It has a very nice look to it and supplements my photo lenses well for video projects.

    • Sirui 50mm anamorphic, what a beautiful!
Style: E-Mount
Review Image by bronwin October bronwin October
The media could not be loaded. What there more to say. Running this beauty on my Sony fx6 and must say, the quality this lens gives off is beautiful and clean. The lens build quality is solid, Aluminum housing cold to the touch which I love. All in all, it’s worth the price.

    • A Great Lens, but...
Style: E-Mount
I tried this with the Sony a6600. It's a great lens, needs a little work in Final cut pro.. but the downsize that had to return this lens is the how far the focus lens travels. It has a small diameter, thus to focus from one point to another would take almost half of a circle or more..cuzing camera shake. If you can live with that, than it's a great lens. Otherwise, I can see this becomes more of a toy than a tool.. an expensive toy that is for $700. ... show more

    • Great entry to Anamorphic Filming
Style: E-Mount
The media could not be loaded. This is a great, incredibly low-priced entry into Anamorphic Filming. I use this on a Sony Full-frame A7III by using clear-zoom to crop into 1.3x (a bit less than shooting crop mode which punches in 1.5x). Sharp lens and has the characteristic anamorphic look and flairs; not as pronounced as a 1.5 or above Anamorphic - but again, a great entry into the process. ... show more

    • Anamorp-AMAZING!!!
Style: E-Mount
This lens is absolutely amazing. The build quality is tough focus is smooth everything on it is easy to use and read it takes some of the most beautiful footage that I've ever seen come out of my camera. I use it with a Sony NEX vg10 camcorder which is outdated but the footage comes out looking incredibly beautiful. I would highly recommend this lends to someone who is looking to shoot anamorphic footage. Buying anamorphic filters and trying to adapt them to other lenses is a headache and this lens is already purpose-built. Truly my favorite lens and all of my lens collection. ... show more

    • Great value! Great craftsmanship
Style: MFT-mount
The Sirui lens is reliable, impressive & a huge discount in price versus other anamorphic lens manufacturers. You can’t beat the price. It makes shooting in cinema style widescreen within the lay person’s reach.

    • In all fairness...
Style: MFT-mount
...I purchased the entire set of Sirui Anamorphic lenses, so this review goes for all the lenses. It's sharp. It's Anamorphic at a very affordable price. And it's not too heavy. Sure, Potato Jet pointed out some flaws, but I'm willing to look over them. Awesome set of lenses.

    • Not the Best
Style: X-mount
In my tests I found it didn’t look much different than simply doing a 2:35 matte with a 50 mm lens. All you’re really paying for is all the blue flares. Something you can easily re-create in resolve.
