Adapters used to be a big deal... with camcorders there were wide-angle adapters. Then for smaller sensors there were speed boosters to try and get shallower DOF and make more use of vintage photo lenses. Anamorphic adapters were always an option / confusing dream. Then "everyone" went FF to get that shallow DOF, and Chinese manufacturing started giving us good quality affordable fast primes and now there seems to be an avalanche of anamorphic lenses (with recent additions including anamorphic zooms, and some even have AF now!). Why are they "back"? Not only can adapters take MFT cameras to beyond FF, or take S35 to FF and beyond, but they can also take FF to Medium Format and beyond as well. The key to this is the emergence of high-quality single-focus anamorphic front adapters, and especially combining them with the new anamorphic glass or with speed boosters or with super-fast native lenses. I realised this when I shot with the GH7 + Voigtlander 42.5mm F0.95 + Sirui 1.25x combination and realised it's the horizontal FF equivalent of a 68mm F1.5. That's not impossible in FF terms, as there are 75mm F1.4 lenses and 85mm F1.2 lenses available, but this was only with the Sirui 1.25x adapter. There are 1.33x, 1.35x, 1.5x, 1.7x, and even 1.8x front adapters available. There is even a PL-to-PL 1.33x rear anamorphic adapter available. Combining the 1.33x PL-to-PL rear adapter with the 1.8x front adapter would be a 2.4x adapter. Not a lot of anamorphic glass over 2x! The combinations are practically endless, and compatibility will definitely be an issue with some combinations, but the thing about adapters is they multiply your lens collection..... If you buy an extra lens then you have an extra lens but if you buy an adapter you multiply your whole lens collection by a factor somewhere between 1-2x, depending on compatibility. Here are couple of worked examples. Just to get the juices going, and as a completely manufacturer supported Full Frame option, Sirui has the Venus anamorphic set, which are 1.6x anamorphics with T2.9 aperture from 35mm to 135mm, with the 1.6x giving them a horizontal crop factor of 0.625, so they're the horizontal equivalent of 22mm to 84mm T1.8 lenses. Add the Sirui 1.25x anamorphic adapter, which is officially part of the set, and they become 2x anamorphics horizontally equivalent to 17.5mm to 68mm T1.45 lenses. This isn't completely beyond normal spherical FF glass, but it's an adapter that can be used across a range of lenses and quickly change the crop-factor of these and many other lenses. Let's go bigger.. Rokinon / Samyang have a 1.7x front anamorphic adapter specifically designed for their Cine V-AF line, which includes 35mm to 100mm T1.9 Full Frame lenses (and a 24mm T1.9 APSC lens) but with the adapter they'll be 21mm to 59mm T1.1. Once again, these aren't impossible to find in spherical versions, but we're getting into more rarified territory. Also remember you now have two lens sets, not one lens set with an extra lens. Would the 1.7x adapter work on other lenses? Not easily - it seems to have a strange proprietary mount to attach to the lenses, which have a 58mm front thread diameter. The Sirui 1.25x adapter is huge and has an 82mm rear thread diameter, so would work on lots more lenses. The Blazar Nero 1.5x has a smaller 52mm rear thread diameter, and the SLR Magic Anamorphot-40 1.33x has an even smaller 40mm rear thread. However, the SLR Magic Anamorphot-65 1.33x has a 82mm rear thread and the Anamorphot-50 1.33x has a 62mm rear thread. I think the BLAZAR LENS 1.35x has a 77 rear thread (not sure), and the Venus Optics 1.33x definitely has a 77mm rear thread. But, if you have the funds and really want coverage, then the Letus35 AnamorphX-PRO series (1.33x and 1.8x) seem to clamp to the outside of 114mm lenses. Of course, they're USD2500 and up! Let's go faster... The Sirui 1.25x adapter claims it's T2.8, but on my MFT 42.5mm F0.95 lens it didn't soften the lens even when shot at F0.95. Maybe it wouldn't be so good if paired with a lens faster than F2.8 on a FF sensor - not sure. If you took an 85mm F1.4 and attached the Sirui 1.25x adapter you'd get a 68mm T1.12 - and an 85mm F1.2 would become an 85mm F0.96! But take the 85mm F1.2 and attach the Anamorphot-65 1.33x instead and now we're down to 68mm F0.90!! My impression was that the FF 50mm F0.95 lenses were pretty mushy at F0.95, but with a 1.33x attached they'd be 38mm F0.71 (and probably like a drug-fuelled haze). You could find out what an F0.71 lens looks like for only USD800 - completely doable if you're crazy enough. If we ignore the compatibility issues, and zoom out, then here's how I think of it - front anamorphic adapters are horizontal speed-boosters you mount to the front of the lens. 1.25x is a 0.8x horizontal speedbooster 1.33x is a 0.75x horizontal speedbooster 1.5x is a 0.67x horizontal speedbooster 1.7x is a 0.59x horizontal speedbooster 1.8x is a 0.56x horizontal speedbooster On FF, you can take a lens and use an adapter to boost your lenses from FF to Medium Format and beyond. The Alexa 65 has a crop factor of 0.67 - which is within reach of these adapters. On S35, you can use an 1.5x anamorphic adapter to get you to FF, but you can combine that 1.5x with a 0.71 speed booster to boost non-mirrorless glass to a crop-factor of 0.71, which is about 6% smaller than the Alexa 65! On MFT, you can use the 1.33x adapter to get you to S35, or combine a 0.71x speed booster with the 1.5x adapter to get you to 0.95 - just bigger than FF! BUT maybe you can push harder than that. No idea! Any discussion that puts S35 closer to the Alexa 65 than FF, or MFT larger than FF would have been unthinkable even a few years ago. Are there caveats? Sure. Compatibility for one thing. The stronger squeeze-factor adapters likely have limits with how fast you can push the aperture and perhaps on sensor size too. I suspect that my Sirui 1.25x T2.8 adapter might only be sharp with my F0.95 lenses wide open because they're MFT lenses on an MFT sensor. I could be wrong though. The smaller rear diameter of some of the other options might cause vignetting on larger sensors, and maybe softer corners at larger apertures. But lens sharpness and shallow DOF are only useful to impress paying customers and for bragging to your friends, and that's not what anamorphic is really for.. so if you're willing to stop acting like you live in a hospital, these things can open up a whole new world. -
I get the appeal. Full frame makes that look easy. The medium format comparison is flattering, not literal. M43 can still do it, but only by design, not by accident. -

Good choice. I think that film-making is about compromises and the more you understand what you're trying to achieve then the more specific you can be with your equipment selection. The "I'll being everything just in case" shooter does so because they don't know what they want and therefore can't make any decisions. The more I shoot the more I understand what I want, how I work, what challenges I face, and what is available, and the clearer I get on what equipment I should use and why. It's sort of incredible that even with todays offerings of 8K video and 240p slow-motion and 14+ stops of DR and RAW and all the lenses available, even if you had infinite money, infinite strength to carry and operate heavy equipment, there are still serious compromises that have to be made. The does-everything camera is still a wild fantasy, even for gym bros in the billionaire class.
