Canon EF-S 10-22mm f/3.5-4.5 USM Lens

Canon EF-S 10-22mm f/3.5-4.5 USM Lens



Excellent super-wide solution for EF-S mount

This lens was created to fill the hole in Canon's range for a super wide angle lens for their range of EF-S mount DSLR's.

Fortunately, since it inhabits a unique position in the range, it is a superb lens and there is no real alternative (from Canon anyway) that covers the same focal lengths.

It's not an L lens so don't expect weather sealing and and lens pouches/lens hoods in the box. Do expect a very well built lens with excellent image quality.

The lens has a very close minimum focusing distance of 24 cm which can be useful for odd effects at the wide end of things. The zoom and focusing rings are smooth and well placed. The lens takes huge filters (77mm) which can add a lot to the purchase price but should be considered essential as the front element is very convex and should be protected. A useful tip - get the slimmest filters you can for this lens as the lens is so wide angle standard filters will cut off the corners a fraction in the frame.

Image quality is excellent. DOF is almost a non issue with this lens as even at minimum aperture and focusing distances greater than close range everything seems to be in focus. There is no appreciable increase in sharpness when stopping down either like you get with some lenses. I leave mine at around f5.6 all the time because I read somewhere that this is the sweet spot for the lens (it's all sweet but apparently this is marginally sweeter). There is a little bit of colour fringing that can creep in for backlit subjects but nothing that can't be edited out and it's par for the course for a lens of this type. What is probably better than normal in terms of performance is the lens' control of flare which is very good. I haven't had flare in my shots even with the sun in the frame. There is no noticeable pincusion/barrel effect either. Solid performance all round.

So if you have an EF-S mount Canon there really are not many choices out there for a super wide lens. It's not the cheapest but it probably is the best out there right now

50Mm 1.8 Canon Lens - Frequently Asked Questions From Potential Buyers

 
By John C. Carter

If you are looking to buy the 50mm 1.8 Canon lens, you may be like many other potential buyers and have many questions in mind. This article will hopefully answer some or all of your questions so you can make an informed decision before buying. You will also learn where to find good deals if you decide to buy this lens.

1. Would this lens be compatible with a Nikon D5000?
No, this lens would not be compatible with your Nikon, both physically and electronically. You would need to get the Nikon 50mm 1.8D AF Nikkor lens for Nikon DSLRs. However, mounting such a lens on a D5000 would limit you to manual focus only.

2. Would it work with Canon Rebel 2000?
Yes, all EF lens will be compatible with your Canon Rebel 2000. However, stay away from the EF-S series lenses, as the Rebel 2000 mirror may hit the rear element or it may result in certain degree of vignetting. Also, the EF-S lenses will not work on many EOS cameras, except on the Canon Digital Rebel line and the 30D through 60D.

In addition, all EF lens will work on Canon's EOS line of cameras. In fact, the EF series lenses were designed particularly for the EOS series of cameras.

3. Does it work with the Canon Rebel XTI?
Yes, the 50mm 1.8 Canon lens makes a great low light or portrait lens for the Rebel XTi. Also, the Canon Rebel XSi uses both EF and EF-S lenses, so this will work with the XSi and you will love the image quality you get from it. Note that the EF mounts are compatible with EF-S but not the other way around.

4. Can I use it with Canon Pro S3 IS?
No, as mentioned above, this lens has an EF mount, and it is compatible with Canon EOS line of cameras.

5. Is this a good lens for night-time shooting?
This lens is fantastic working under low-light conditions. It is excellent for capturing a band performing or musical performances, although it may not be suitable for fireworks or storms.
In general, the Auto Focus will have some difficulty under dark situations, such as lightning and fireworks. You can try manual focus if you really need to capture a picture when the light lasts very briefly. Another alternative is to auto- focus on something else that is about the same distance away as your subject. Then, shift the focus to manual and leave the dial alone. Stop down the aperture will also help.
