A flexible wide-angle zoom in a compact form factor, the EF-S 10-18mm f/4.5-5.6 IS STM from Canon is a 16-28.8mm equivalent lens designed for EF-S-mount DSLRs. Helping to reduce the overall size while maintaining high optical quality, a four-group zoom design is employed along with one ultra-low dispersion element, one aspherical element, and one large-diameter element to produce sharp, clear imagery void of chromatic and spherical aberrations. A Super Spectra coating has also been applied to suppress flare and ghosting for increased contrast and color neutrality. Benefitting both photo and video applications, an STM stepping AF motor is used to realize quick and near-silent autofocus performance along with full-time manual focus override. Additionally, a four-stop-effective Image Stabilizer system is also featured and minimizes the appearance of camera shake for sharper handheld shooting.

EF-S-Mount Lens/APS-C Format    16-28.8mm (35mm Equivalent)    Aperture Range: f/4.5 to f/29    One UD Element & One Aspherical Element    Super Spectra Coating    STM Stepping AF Motor    Optical Image Stabilizer    Rounded 7-Blade Diaphragm

Wide-angle zoom is designed for APS-C-format Canon EF-S-mount DSLRs and provides a 16-28.8mm equivalent focal length range.

One ultra-low dispersion glass element noticeably reduces color fringing and chromatic aberrations for high clarity and color fidelity.

One aspherical element limits distortion and spherical aberration in order to realize greater sharpness and accurate rendering.

Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions.

An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to four shutter speed stops to better enable working in low-light conditions and with slower shutter speeds.

An STM stepping AF motor realizes smooth, near-silent autofocus that is complemented by a rear focus system, advanced AF algorithms, and a high-speed CPU for fast AF performance. Additionally, full-time manual focus override is also available.

Rounded seven-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.

Q: 1. Will this lens work with 5d mark iv?

A: even if you manage to fit it with an extension tube the result will be crappy, have a look at this link: https://youtu.be/7XG5YcG3sxM

Q: 2. Is this lense compatible with a Canon EOS Rebel T3?

A: Yes, this lens is fully compatible with the Rebel T3 camera.

Q: 3. Would you recommend this for video with a 7D camera? If not, what would you recommend?

A: It's really a great little lens. I have never tried it on the 7D for video though. We did try it on a T2i for video and it did what we needed. I guess it depends on how wide you need. For the $$$, it has been a fun lens.

Q: 4. will this lens work for my eos T3i?

A: Canon's ef-s lenses fit all aps-c sensored eos cameras. this is a great lens for landscape photography.

Q: 5. will this lens work with the rebel eos xsi?

A: Yes. In fact I bought this lens for my wife's XSi and she is very happy with it and has taken some very good pictures with it.

Q: 6. I have a rebel t1i and would like a nice wide angle lens for landscape and for a trip to Europe. I'm debating whether I should get the 10-18mm or 10-22mm with no IS. The 10-18 is significantly cheaper which is a huge plus but I'm not necessarily set on that. Any suggestions or better recommendations?

A: IS is less important with ultra wide lenses and landscape photography often involves a tripod. Although I like this lens for the price, I cannot honestly say that I am amazed with the results. I say this because some lenses have a nice, contrasty pop to them. The adage you get what you pay for is often true with photo gear. Often times when I went cheap I have regretted it. Again, this seems to be a fine lens with a not so great build quality. I used to have the Sigma equivalent (10-20) with a Nikon camera and the images were a good stretch better, but the lens was twice the price and twice the build quality. No IS though. Bottom line, I think it is a good, all around cheap lens. If you are serious I would try renting different lenses form Lensrentals or Borrowlenses and compare them before buying.

Q: 7. Hi can I use this lens on my canon 750d? Thanks

A: Yes. It's a wonderful lens even for a budget wide angle.

Q: 8. Hi I am considering buying either the EF-S 10-18mm f/4.5-5.6 IS STM or the EF-S 24mm f/2.8 STM which will you recommend? I can only buy one.

A: I have both. The answer depends on your need. I use the 10-18 for wide angle shots. It is light weight and I find it sharp. Much cheaper than the 10-22 and very easy to carry in a bag. Has a plastic feel to it but works great. I don't use the 24 as much b/c I have the 40. The 24 is also sharp and I use it to shoot video from a tripod at family events. The 24 & 40 are easy to carry and great for general photography as long as you are not looking for tight shots. I like the flexibility of the 10-22 although like all wide angle lens you probably shouldn't use it for close ups. I use it for landscape and beach shots.

Q: 9. Will this lens work with 5d mark ii?

A: YES! This lens will work on a full-frame camera with just a bit of work, just like Kambiz says. I took a cut off wheel to mine and it works perfectly with a 5D 2 and 3. I can't express how beautiful it looks recording 3k raw video with Magic Lantern and this lens. Wouldn't advise moving the mirror at under 12mm though ;)

Q: 10. Hi, I'm using Canon SL1 with the bundled 18-55 lens. How significantly wider would be this lens?

A: The human stereoscopic angle of view (in focus) approximates 120deg. With one eye only, it approximates 100deg. The Canon 10-18mm angle of view is 107 to 74deg. This may be a dumb comparison but it does give us an idea of how wide this lens is. The important thing is, facing for example the huge Sagrada Familia in Barcelona, that the human eye (even with one eye only) can take the whole frame, the Canon 10-18 does it also, whereas the 18-55 won't do it.
