Panasonic S1 with the Sigma MC-21 - autofocus test with 12 of my EF lenses

EDIT: Note the title text at the beginning of the video and the thumbnail says 15 lenses, it is in fact only 12, apologies. I have both the Panasonic S1 and Sigma MC-21 on loan for a couple of weeks. One of the tests I wanted to perform was to see how many of the EF lenses that I personally own would work with this combo. Officially the MC-21 is only meant to work with Sigma lenses. But it turns out every one of my EF lenses works with the S1 and MC-21. That is, to be clear, the camera is able to control the aperture of all the lenses, which is the most important element, as all the EF lenses I own have electronic aperture control. So in practice this means at the very least all the lenses are able to used for both video and stills in manual focus, and the camera is able to control the aperture whether in Manual, Aperture or Shutter priority modes. When it comes to autofocus the MC-21 is only able to work in AF-S (single) mode, and cannot work in a AF-C (continuous) mode. So for video this is really a non-starter in practice, and therefore you have to accept that when filming you really need to use it with manual focus - which is fine by me as I only ever film in manual focus. With stills however, autofocus is the norm, and so this test is to see how well each lens performs. Note: I performed the test in the P (program) mode to demonstrate the camera being able to control the aperture of each lens. The reality is that although all of them work in autofocus (except the Sigma 105mm macro), the speed of autofocus is much slower than the native lenses. This is fine for landscapes perhaps, or even portraits, but not really good enough for sports I'd say. Although as it happens the Sigma 150-600 Sport lens is probably the fastest to autofocus amongst all my EF lenses when on the S1. This is the list of lenses I test in this video (in this order): FULL FRAME LENSES: Tamron 15-30mm VC f2.8 Sigma Art 20mm f1.4 Canon 24mm IS f2.8 Sigma Art 24-105mm f4 Canon 35mm IS f2 Tamron VC 45mm f1.8 Tamron VC 85mm f1.8 Sigma Macro OS 105mm f2.8 Canon L 70-200mm IS f2.8 (mk1) Sigma Sport 150-600mm f5-6.3 APS-C LENSES Tamron VC 10-24 f3.5-5.6 Canon EF-S 17-55 IS f2.8 Note the APS-C lenses are mainly good for filming in 4K50/60p as that mode crops to APS-C. The Tamron however is also good for stills from 15mm onwards.
