CanonEFS 10-22mm f/3.5-4.5 USM Lens Bundle Value Kit with Filter

The lense came in great condition: nothing was missing, nothing was broken. The lense for photography of architecture is absolutely on point considering the price of the lense.

The ultra wide zoom has been a mainstay of pros, especially photojournalists, since the early 1990s. Sweeping landscapes, operation in tight quarters and ease of hand holding are hallmarks of this range. The EF-s 10-22 3.5-4.5 USM is the first lens to bring this range to APS-C (1.6X crop) cameras like the 7D, 60D, 70D and Rebel.CONSTRUCTION: My initial impression was it's a little plasticy and zoom and focus rings are slightly coarse and stiff. After a year, it loosened up nicely but is still a notch below the smoothness of my EF-s 15-85 3.5-5.6 IS USM. However, it's light and petite: easy to slip in a coat pocket and ideal for travel or hiking. The metal mount and polycarbonate barrel make it durable yet lightweight. The front element moves slightly during operation so a UV filter is needed to seal the front from dust.AUTO FOCUS: Ring-type USM drives an internal lens group and, thus, AF blazes and is silent to human ears. The front element doesn't rotate during focus and zoom operations. It has FTM, allowing manual focus without switching out of AF mode. This AF design is optimized for stills and not ideal for video: the built-in mics on my 60D and 70D picked up a high pitched stutter from the motor and contrast focus is jerky during video recording. The workaround is to use an external mic and/or focus manually. If video is your main thing, buy the Canon EF-S 10-18mm f/4.5-5.6 IS STM instead as the STM drive is stepless and silent to the camera mic.OPTICAL PERFORMANCE: Basically, this lens features optical quality of an L series wide zoom in a prosumer barrel. Wide open, this zoom is sharp and contrasty in the middle of the frame with slight softening towards edges. The wide side is the sharpest with slight degradation as you zoom towards 22mm. Sharpness across the frame improves as you stop down. By F8 it is pin sharp from edge to edge. I'm going for increased depth of field for landscapes and cityscapes, so I leave this lens at F8 most of the time. I only shoot wide open for occasional low light snaps.Distortion is well corrected. There is a wee bit of barreling at the wide end and slight pincushion ate the long end. But less distortion than my EF-s 15-85 3.5-5.6 IS USM and a little better than the 17-40 4L USM. Like any wide angle optic, you need to compose carefully to avoid perspective distortion, e.g., noses appearing too large or buildings falling over.Chromatic aberration is a reality with zooms and this one is not exempt, with magenta fringing along high contrast edges. e.g., tree branches against a bright sky. However, it is mild and easy to remove in DPP, LR or Aperture. In normal light you will never notice magenta fringing.Flare is well controlled for a zoom: no problems with sunsets or streetlights. Nevertheless, a lens hood is recommended for protection and to shade the front element from glare. Speaking of hoods...HOOD NOT INCLUDED: The recommended EW-83E hood is bulky and (looks like a dish) and costs $32. Worse of all, it's so shallow it offers little protection. I have an EW-83H that came with an EF 24-105 4L IS USM. The bayonet mount is the same size as the EW-83E but the hood is longer and narrower, offering increased protection. I thought the longer length might vignette but, amazingly, it doesn't vignette at any focal length, has better protection from glare and less bulk than the EW-83E. If you're going to spend money on an expensive hood for the 10-22 3.5-4.5, get the EW-83H instead of the EW-83E. If you're on tight budget, check out the Vello EW-83H clone/knockoff.LAST BLURB: This zoom is a specially lens and a bit wide for casual use. After all, 10mm covers 107 degrees! Nevertheless, I reach for this lens to shoot cityscapes, landscapes or in tight quarters. If you need an ultra wide zoom on APS-C, this is among the best in terms of image quality: sharp, fast to focus and easy on the shoulder.

Only fits my lower end camera. Does not mount on my new Canon 6D, only on my older T7.

I tested this lens with a T3i body and B+W polarizer. Results were unbelievably phenomenal. Too bad Canon has not come up with its EF equivalent yet. You will love this for landscape photography if you have a T3i.

This is a nice wide angle lens but the edges of the picture do warp a little.Overall given that there are very few wide angle lens out there for canon, this is quite a good lens.
