EF-S 24mm f/2.8 STM

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.

5I was hoping for something more compact that would be great to throw in a rucksack for a day out ...
By Stuart
I currently shoot mostly with the canon 50mm 1.4. I was hoping for something more compact that would be great to throw in a rucksack for a day out hiking, or at least just something less bulky. I figured with a 180$ lens, if it was only OK I wouldn't be too depressed about it. I have been continuously impressed with this thing, and I foresee this being as vital a cog in my photo arsenal as has been my 50mm. Yes, it is compact, it actually fits in a zipper pouch in my daypack that I previously had to separate the lens from the camera in order to be able to accommodate it all. It's wide, and can really capture the scenery as I have included in the pics I took, and has the same great bokeh effect with a fast 2.8 aperture that my 50mm has (well not AS much, but good nonetheless), which I love and need. One surprise I didn't realize was that it has such great macro capabilities, I mean I am like 2 inches from the subject and it focuses right in on it, bam. I can't tell you how thrilled I am to have such a multitasker for my adventures, I can take a picture of a weird bug, pretty flower, and capture the sunset nice and wide, or a portrait of a person. I crave, no NEED multitaskers in my gear, I am not a professional, and I like my dollar to stretch as far and wide as it can. I am very happy with it so far. The image quality appears to me to be really good. The autofocus is fast, works really well even in lower light situations. Yeah, there are a few things I would defer to my 50mm 1.4, but these two together make me a very happy photographer.

5A must have lens for Canon T5i, T6i, 70D or 7D!!
By Tech Geek Reviews
[[VIDEOID:bb68e22529be8deac725648c7efcafd3]]Attention pancake lovers: while not making as splashy an entrance as Canon EF 40mm f/2.8 STM Lens, the 24mm EF-S is a terrific addition to your lens arsenal. In a nutshell, the 24mm STM pancake provides excellent optics at a highly usable focal length, encased in a quality compact chassis making this an ideal walk-around prime for crop sensors. Here is a break-down of the reasons why I think you should own this:

-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. What good is a bulky DSLR that you don't carry? Trim the space to this incredible size and you are more likely to carry it with you!

-OPTICAL CHARACTERISTICS: Quality optics, Canon does not disappoint here: Excellent sharpness, minimal chromatic abberation, no significant vignetting. You are getting a very nice lens!

-FOCUS MECHANISM: Uses an STM stepping motor, while not as fast or quiet as several of the other lenses of the STM class, it is still an improvement over non-STM lenses. Also has full-time manual focus.

-MINIMUM FOCUS DISTANCE: Minimum focus distance is 6" so it can be used as a semi-macro lens. (See my video for close ups)

-BUILD QUALITY: Excellent construction. Has the exact same high quality, durable frame, metal mount and solid feel as the 40mm pancake. No doubt the lens will last a long time.

-FILTER SIZE: Small filter diameter 52mm, allows you to purchase better filters for less money.

-COST: At $150, it's an incredible bargain. (Note: there are several sellers charging far greater than the retail price. If the Amazon price is high, wait a day or two to order as the typical sellers replenish their stocks.)

-IMAGE STABILIZATION: This lens lacks IS. Fortunately at the shorter focal length, you can get by with a faster shutter speed to achieve good hand-held results.

-FORM FACTOR: This is an EF-S lens (note the WHITE square) means it is only for crop sensor Canons (t5i, 70D, 7D and their predecessors) and will not work on full-frame sensors Canons (1D, 5D, 6D). Therefore the lens will not "cross-over" if you decide to upgrade in the future. The 40mm pancake will as it is an EF lens (note the RED dot).

-FOCUS MECHANISM: Not a huge deal but, because it's "focus by wire", it requires power to use the focus ring

-MANUAL INDICATORS: No distance indicators for focusing. Frankly not a big deal.

5 Stars. You won't be disappointed with this lens!

5Works well for astrophotography.
By Okieplainsdrifter
It's just a great little lens as others have said. Works well for astrophotography. A small amount of coma wide open but stopped down to f4 it's great.
