Fantastic lens for the price and weight.

Autofocus Lens is a compact and portable macro lens meant to introduce novice photographers to close-up image-making. Its cost, design, and overall size all lead the tyro to comfortably accessorize their kit lens, and begin developing a library of optics for their camera.

Worth every penny, chose this instead of 50mm prime. its fully worth of 2K extra money... suggest you to go for this.. it produces stunning pics at f/2.8 compared to 50mm's f/1.5

There was a lot of hype after Canon's release of the 40mm pancake lens & I wondered if it was worth getting this inexpensive prime lens versus saving up for L glass for 10X or even 20X the price & made the leap when the price dropped.

The EF 40mm f/2.8 STM is a fairly unprepossessing little lens, and its tiny size and relatively low price might make you wonder whether significant compromises have been made in its design and construction.

Very good optics; Tiny size; Silent autofocus; Responsive electronic manual focus; Decent construction; Low price

Can be susceptible to flare; No lens hood supplied; AF speed isn't the fastest

The Canon EF 40mm f2.8 STM is the company's first 'pancake' lens, designed to be as small and light as possible. Measuring just 22.8mm thick, it protrudes to roughly the same degree as the grip on many DSLRs, and at 130g you'll hardly notice it when mounted.

Handling and features The Canon EF 40mm f/2.8 STM is a slim, compact pancake type lens, which is compatible with Canon EF and EF-S camera bodies and costs around ￡230. A fast f/2.8 aperture should make this lens ideal for taking pictures in reasonably low light conditions and focusing is powered by...

The Canon EF 40mm f/2.8 STM is an appealingly simple, compact and capable lens that's equally at home on an APS-C or full-frame DSLR camera. It's also very cheap, making it a worthy addition to any EOS user's camera bag.

Good bang for the buck. Works on full frame or C sensor cameras. So small it makes even the biggest camera usable anywhere. Good in low light , no flash situations, and auto focus works quite well.

"This is a fun and sharp little lens. I own the 50mm f1.8 as well, and I prefer the 40mm. Why Better build quality, the 40 is similar construction to my 18-135mm STM, better image quality than the 50, quieter auto focus, and a slimmer profile.
