Fotografie: Canon EF-S 10-22 / 3.5-4.5 - Hands on Review

Copyright by Michael Bockhorst 20 12 09 - 14:53
You love ultrawides? You are in the decision process to buy one? Painful ... but hopefully this article helps you.

Why an Ultra Wide?

In my opinion, the right process to choose a photographic tool is to identify the way you want to take photographs. There is no single all purpose lens with ultra high quality, high aperture and really omnipotent zoom range.

If I look for a lans as photographic tool I have to decide

  • What do I want to express by the use of that tool?
    → Focal length or zoom range? = Perspective control
    → Maximum aperture? = Available light photography
    → Maximum reproduction ratio?
  • Where is optical quality critical?
    → Contrast and color reproduction
    → Sharpness
    → Distortions - software based correction decreases sharpness, not easy in movie mode!
    → Flare resistance - Flares cannod be corrected afterwards!
    → Falloff - software based correction fine if cameras dynamic is good enough
    → Lateral Chromatic Aberretions - software based correction works great
  • Useability considerations
    → Good Focus (resp. zoom controls)
    → Manual AF override possible or not/necessary or not?
  • What weight/size is acceptable?
  • What do I want to pay?
  • Compatibility with other systems - crop or no crop optics?

Decision process

The following listing show my decision criteria for an ultrawide for my EOS 40D Crop systems:

VERY IMPORTANT - IMPORTANT - NOT RELEVANT
♥♥♥ = Very good - ♥♥ = Good - ♥ = O.K./Acceptable

  • What do I want to express by the use of that tool?
    → ♥♥♥ Focal length or zoom range? I want: Exaggerated perspectives/differences / Overview photographs in limited space / large DOF / Range from Ultrawide of ca. 16mm equiv to 35mm equiv
    → ♥ Maximum aperture? = short focal lengths allow for longer shutter speeds, action photography under available light conditions not too important for me (use the 24mm/2.8 for that)
    → ♥♥ Maximum reproduction ratio? = really important for me, should never be above 1:10
  • Where is optical quality critical?
    → ♥♥♥ Contrast and color reproduction = The contrast and colors are great. This is essential for all types of photography - the sharpness is not the most important thing for ultrawides.
    → ♥♥ Sharpness just two hearts! The behaviour of the lens is a little bit weird. Good Focus and F5.6 - F11 guarantee good to very good sharpness. The extreme borders need F11 to be tack sharp.
    → ♥♥♥ Distortions - Near 1 percent, not penetrating just at 10mm! Great for architechture and movies
    → ♥♥ Flare resistance - Flare resistance is great and absolutely necassary - Ultrawides capture a large angle of view and you will capture lightsources like the sun very often.
    → ♥♥ Falloff - = works fine, but very often a fallof helps to attract viewers eye to the main subject. Use falloff artisically and correct it artistically.
    → ♥♥ Lateral Chromatic = moderate, correction via DPP works fine
  • Useability considerations
    → ♥♥ Good Focus = controls are good despite of the plastic dominated appearance
    → ♥♥♥ Manual AF override = YES! its an USM lens
  • ♥♥♥ What weight/size is acceptable? = just 350 grams! / ca. 85 (dia.) x 90 mm
  • ♥♥ What do I want to pay? = not every price, but better have a few really good lenses than a bunch of it with lesser quality
  • Compatibility with other systems - this lens is not suited for full framers, but the great correction of distortions will be a good addon for videos with a crop sensor body because distortion correction for movies is much more tricky and will leed to harsh quality losses.

Conclusion

Except some weaknesses in terms of sharpness the EF-S 10-22 lens is a great tool for architecture, landscape and allround photography. That system is not cheap but the combination of optical properties, zoom range and usability features make it a great tool from ultrawide to the classical 35mm equiv focal length. The close focus capability of 24cm @ 22mm helps to pick up the EF-S 10-22 as a single walk around lens and avoids lens changes.

It's up to you: If you plan to go to full frame in the next months: Wait for it. If you want to make movies by use of ultrawides - gives great effects - wait for a good body in the low price APS-C-Range of Canon. Or buy a EOS 7D.

With it I bought a 77mm B&W UV Filter to protect the front lens and to avoid dust succing by the variable front group.

SAMPLE IMAGES

All images were derived from RAW via Canons DPP. Sharpness: +3 units, Lens correction: CA correction only, moderate changes of contrast, brightness and black/white point. Color adjustment: Daylight or Manual Kelvin Settings.

Distortion was never corrected - it's slightly visible in some architecture photographs but far from that of all the other lenses with that focal length.

All samples are made at 10 mm.
