First time in ages i got away for a few days and did a road trip out to a little country town i like to visit.
Full discloser, never really considered myself, much of a cleanliness or sterility freak 🙃. However i am liking the sirui 1.33 24mm. Probably mostly for the convenience it brings. Its not 1.5, 1.6 or 2x, and i think the anamorphic effects are kinda tame compared to those other stretches i mention.
I liken it to stepping stones i think, little bit different to what you'd normally see but not as jarring as 2x ( although jarring might be too strong an adjective). It will flare and do the blue streaks as well but i find the blue streaks to be less intrusive compared to what you see on youtube. I suspect the first prototypes steaked quite a lot in youtube videos, no idea if they toned them down. My experiences has been their abit more subdued.
The anamorphics guy Tito Ferradans has a vid on using oval cutouts in sirui lenses. I'd probably try something like that next. If i wanted a look that was closer to 2x Its taken a while to figure this lens out and i expect i still need to do more with it to realize its potential.
The whole sterility / cleanliness thing, is of course subjective. What you may like, i may not and vice versa. I personally don't find cleanliness and or sharpness objectional in a lens and i recently bought a lens with a whole lot of yellowing going on that most wouldn't buy.
I think the sirui and the other modern anamorphic lenses bring convenience to anamorphics. Buying a vintage anamorphic is much like travelling down a rabbit hole. Theres lots of things to add on and sometimes that can take a while to sort out.
Its my understanding that 1.33 are geared towards crop sensors and the bigger stretches for full frame ? of course you can mix and match, if you so desire.
i'm on mft format and i think 1.33 stretch adds enough of a difference for me. i also suspect a 1.33 stretch is a good start, if your looking to dip your toes in anamorphics and have a crop sensor camera, but dont want to travel down a rabbit hole.
