EF-S 24mm f/2.8 STM
Incredibly lightweight, the EF-S 24mm f/2.8 STM is a fast and versatile lens with advanced AF and superior optics. With a 35mm equivalent focal length of 38mm, it's appropriate for a variety of purposes. The lens features optimized lens element placement and includes an aspheric element for high image quality from the center of the composition to the corners, and has specialized coatings on the lens elements to reduce ghosting and flare. To ensure excellent color balance, a 7-blade circular aperture provides superb out-of-focus detail. The EF-S 24mm f/2.8 STM excels during movie shooting thanks to its STM motor that enables silent and smooth focus tracking (on EOS cameras with Movie Servo AF), plus a micro-stepping drive that keeps aperture changes quiet. The lens also offers full-time manual focus, manual AF adjustment (one-shot AF), and can focus down to a minimum distance of 0.5 ft. (0.16m). Delivering optical brilliance in a lightweight and unobtrusive construction, the EF-S 24mm f/2.8 STM is a great fixed-optical length lens for photographers looking to add a travel-friendly option to their collection.

-FOCAL LENGTH: At 24mm on crop sensor(Canon t4i, t5i, t6i, t6s, 70D, 7D), the effective focal length is 38mm, which is an excellent frame size for general all around shooting. (Hence I believe this lens will do for crop sensors what the 40mm did for full frame.). The 40mm pancake is just too narrow on the crop sensor as a general purpose lens making it difficult to take indoor photos (you will back up into walls).
-APERTURE: Aperture is f2.8 which is a full stop larger than the f-stop on kit lens 18-55mm at the equivalent 24mm (recall the kit lens minimum of f3.5 is only available on at 18mm and increases as you increase focal length). This means the 24mm pancake delivers better bokeh thru smaller depth of field to separate your subject from the background. It will also let in greater light for better indoor pictures without flash. Of note, while the f2.8 is the same on both the 24mm and 40mm pancakes, the DIFFERENCE of aperture size compared with the kit lens is much greater on the 40mm (f5.0 on kit lens at 40mm and f3.5 at 24mm). This makes the relative improvement greater on the 40mm than on the 24mm, but still a good improvement over kit lens.
-SIZE: SMALL! Yes, this is probably the number #1 reason this lens is of interest.Read more ›
BUILD: This lens is only a little larger than a body cap, hence the pancake moniker. Although compact, it is robust in construction: metal mount, sturdy plastics and black matte finish. The EF-s mount only fits APS-C (1.6x crop) cameras like the Rebel and 70D (not for full frame). There is no distance scale and it uses 52mm filters.
IMAGE QUALITY: Field of view is equivalent to 38mm on full-frame and, coupled with its fast F2.8 aperture, is ideal for candid and low light photography. Wide open it's tack sharp center frame with smooth bokeh in defocused areas. Corners are a little softer and darker than center but equalize by stopping down to F4 or higher. In short, image quality is excellent open wide and a little better stopped down.
AUTO FOCUS is peppy and faster than the EF 40 2.8 STM. Minimum focus distance is six-inches, allowing for quasi-macro shots. Most significantly, AF is accurate and rarely misses on my SL1 and 70D. Focus is buttery smooth and great for touchscreen pulls during video. The focus motor is very quiet--a pianissimo "sheeek"--but may be picked up by built-in camera mics during video recording. Workarounds include using an external mic or focusing before recording.
MANUAL FOCUS is "focus-by-wire"; i.e., the MF ring activates the focus motor but isn’t mechanically coupled to the lens. The tiny nested barrel moves during focus, growing slightly longer at close focus. Full-Time Manual (FTM) allows AF override without flipping a switch: simply turn the MF ring.Read more ›
