It is useless for 35mm, full-frame and 1.3x cameras; it won't even mount on them. Specifications top. Intro Specs Performance Recommendations . Name. Canon calls this the CANON ZOOM LENS EF-S 18-135mm f/3.5-5.6 IS STM. EF means "electronic focus," meaning that there is an autofocus motor in the lens itself. All Canon lenses since 1987 have been EF. The Canon EF-S 24mm f/2.8 is compatible with all Canon EF-S mount systems. It even works on newer RF mount cameras like the EOS R, R5, and R6, as long as you have an EF-to-RF lens mount adapter. It’s NOT compatible with EF full-frame cameras like the Canon 5D Mark IV, 6D Mark II, and 1DX Mark III. 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. 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. Here's another extreme example, the 3/4 full moon directly in the image, and there's no problem. Moonlight. Canon 28mm f/1.8 at f/4, 15 seconds at ISO 400, full-frame Canon 5D. The Canon 28m f/1.8's lack of flare and ghosts make it ideal for use in available light where you may be facing a window indoors or have stage lights shining at you. Check which focus mode you are in. Full Time Manual Focus does not work in AI Servo mode. It is probably because the AF is continually active in AI Servo. Here is what I have noticed with all my STM lenses: In One-Shot Auto Focus, the focus can be fine tuned (Full Time Manual focus) anytime the shutter is half pressed. The EF 40mm f/2.8 STM is Canon's first ever EF pancake lens. Featuring a fixed focal length of 40mm and bright f/2.8 aperture, Super Spectra coatings that minimize ghosting and flare, a circular seven-blade aperture, a newly developed stepping motor for smooth and quiet continuous AF while capturing video, and a short minimum focusing distance of only 0.98ft/0.30m, the ultra-slim Canon 40mm f Canon Lens EF-S 24mm 1:2.8 STM 52mm Macro 0.16m/0.52ft, With Caps. $89.95.
