Canon announced the RF 10-20mm f/4 L IS STM lens, a groundbreaking full-frame ultra-wide-angle lens that expands upon the legacy of the popular EF 11-24mm f/4 L thanks to optical advancements and The Canon EF-S 24mm f/2.8 STM is the sharp, compact, and inexpensive lens that every Canon shooter should own. its field of view is just a little bit wider than the 40mm on a full-frame body Když objektiv Canon EF-S 24mm f/2.8 poprvé vezmete do ruky, možná se podivíte tomu, že toto může vůbec fotografovat. Je totiž opravdu mrňavý. Tloušťka objektivu je pouhých 22,8 mm a šířka jen 68,2 mm. S hmotností 125 g se jedná o vůbec nejmenší objektiv, který firma Canon vyrábí. RF – designed for Canon’s R-series mirrorless cameras. EF – designed for all of Canon’s EOS cameras, including full-frame digital, APS-C digital, and 35mm film. The EF stands for electro-focus. It was introduced back in 1987. EF-S – designed specifically for EOS cameras with APS-C cameras. In some cameras, putting an EF-S lens on a Canon EF-S 10-18mm f/4.5-5.6 IS STM; I personally like the 20 to 24mm (full frame equivalent 35 to 40 mm) focal length for non-astro landscape. For dramatic Milky 40mm is a very useful focal length on full-frame, which is why just about all the film compact cameras of the 1960s to 1980s had lenses with focal length between 38mm and 45mm. The half-frame (near enough digital APS-C format) cameras tended to have 28mm lenses though, for a similar field of view. Specifications: Canon EF 50mm f/1.8 STM Lens : Year Introduced: 2015: Mounts On: Full-Frame, APS-C: Lenses / Groups: 6/5: Angle of View: Diagonal: 46º: Angle of View Much better served by a Tamron 17-50 f/2.8 or Sigma. On full frame, it's a nice option, but again, I think even the 24-105 f/4 would be a better pick on vacation (though it's much heftier). 24mm has a field of view (on full frame) that is wide, but doesn't immediately scream wide angle like lenses wider than 20mm. oih9vl.
