Sirui 75mm f/1.8

• Anamorphic Lens by Sirui
• Single Focus : Synchro Focus
• Mount: E, MFT, X, EF-M, RF, L, Z

Gotta say, I was hoping for this one, but it’s a surprise to a lot of people! Everyone wanted to go wider, but not everyone thought how good anamorphic would look on a longer lens!

Alright, what else is there to say about Sirui lenses? These folks are fast at putting out lenses and they hardly ever disappoint! Construction is solid and mechanics feel decent. We’ll see how that holds up in a future video when I need to go in and put an oval insert in there.

In every way, this 75mm follows the lead of its predecessors.

It’s lightweight at 800g on average through the different mounts, and compact, perfect for a mirrorless rig. On the risk of repeating myself, this lens is only compatible with mirrorless cameras, and you can pick from five different mounts: MFT, X, E, Z or EF-M (not the same as EF).

It features 67mm front threads for filters, which I recommend stepping up to 77mm as a standard across the set. Aperture is impressive at f/1.8 again like the 50 and 35mm, and the focus ring has just over 180 degrees of throw.

Minimum focus is slightly further on this lens compared to the other ones, at 1.2m, or 4ft, which is pretty decent for a longer lens. This reflects on a stronger squeeze factor at minimum focus. The variation on this lens goes from 1.33X at infinity to 1.3X at mins.

I’d still just get diopters for closer subjects and keep the focus ring set more towards infinity to avoid these changes!

No issues with sharpness. It’s crazy to get a sharp long lens in anamorphic. A lot of DIY setups can’t handle fast apertures or longer focal lengths due to non-optimized focusing optics, but that’s far from the reality here. Get eyes pin-sharp. A great deal of the sharpness we see in the Sirui lenses comes from the lesser squeeze factor, by the way. Less curved glass helps with keeping aberrations in check. Good on them!

Flares are the same. Not as hardcore as the 24mm was, though. Which is good. The subtle and larger flares created by the 75mm give an organic vibe to the images.

For coverage, this lens is, again, designed for S35 or APS-C.

Bokeh is more noticeable thanks to the longer focal length, but 1.33x is still subtle. I plan to mod this lens as well for squeezier bokeh, especially because we can afford to lose some light in exchange for better ovals! In any case, 75mm is awesome to create stronger background separation and have your subject pop - especially considering how sharp the lens is!

My current guess is this rounds up Sirui’s original set, which also establishes them on the consumer anamorphic market, promoting a big change on the landscape in terms of affordability. I bet we’ll see them move to more challenging designs tackling either the all-time popular EF mount, stronger squeeze factors, or full frame coverage. Any of these advances would promote another wave of awe from the users dissatisfied with the current offerings.
