The main question here is if we know if future APS-C mirrorless from Canon (i.e. the upcoming M50 upgrade) will feature an RF mount or continue with the EF-M mount. Canon's made no mention of this. M can use all EF-M, and EF/EF-s with adapter. R can use all RF, and EF/EF-S with adapter. Until Canon says different, I'd expect this to continue. For Canon EF-S Mount: 26mm. Canon EF-M Mount: 18mm. For Canon RF Mount: 20mm Canon EF Vs EF-S Lenses You can use Canon EF lenses on both Canon Full-frame and APS-C DSLR camera bodies. But, you can use Canon EF-S lenses only with Canon APS-C DSLR cameras. It is one of the major differentiating factors. The EF-S 55-250 IS is a nice, light and compact travel zoom. But you also could get the EF 70-200 series or 70-300 IS L lenses instead, they are heavier, but also better and work find on full frame. Anything starting with a focal length of 70mm and higher is EF only anyway, because EF-S would not gain anything. The EF-S 55-250mm f/4-5.6 IS STM lens features one UD lens element that reduces chromatic aberration, helping to achieve excellent image quality with high resolution and contrast. The front element does not rotate, ensuring easy compatibility with accessories like polarizing filters, and full-time manual focus is available even while in AF mode. All Canon EF and EF-S lenses are DSLR lenses so Canon DSLR lenses can be used on mirrorless cameras with an adaptor. Whether a crop factor is applied depends on a number of factors, but if there is a crop factor it is 1.6x for Canon mirrorless cameras. This post focuses on people with Canon DSLRs and EF/ EF-S lenses moving to a new Canon Glassless adapters to Canon EOS (aka the Canon cameras that use modern EF lenses) for many FD and FL lenses that maintain infinity focus are now available from edmika.com, a Canadian company. By using a superduper liquid crystalline engineering polymer instead of metal, Jakub (Ed is his middle name) is able to make really, really thin adapters EF 70-200mm f/2.8L IS II USM vs l. I have an r7 with an ef adapter, wondering is the extra 300 gbp worth it (buying used) Thanks. Seconding this OP, I've got the II, and went for it after a lot of research that it's the sweet-spot of price/performance between the I, II and III. Yes, optically it's a decent improvement over the Mk I version and Although if you were really into portraits, you might want to get the adapter for EF lenses and get a 50 or 85mm. bay-to-the-apple. • 5 yr. ago. The 32mm is sharper but I would still pick the 22mm because I'm always in tight spaces/indoors when using my m50. It's my dream to have the 32mm for use outdoors or large venues at night. 1. jxuc.
