My equipment:
Canon EOS 60D
Canon EOS 1D Mark II
Canon 4.0 / 70-200L IS; Canon 4.0 / 24-105L IS; Canon 1.8 / 50; Tokina 2.8 / 11-16 DX
After I only with relatively light equipment'm traveling for 3 years, I had to reduce health vigorously the weight of my equipment, I am now landed exclusively at Canon 2011.
No compiled equipment weighs no more like 2 - 3kg.
Take as little as possible, for high-quality equipment, and to work, so I deserve my money now times, optimally design and hold the post on the PC as minimal as possible.
The above 4 lenses guarantee for all shooting situations best results - all used on Canon 60D and 1D Mark II, therefore rated at these cameras.
Focal length of Canon APSC 17.6 to 25.6 / APS-H from 14.3 to 20.8
Ideal combination for Canon 4.0 / 24-105L IS
Plus points
+ Sharply Aperture 2.8 in the image center to the outer edge, extremely wide angle typical, weaker but not really disturbing, beautiful art work possible
+ From Aperture 4.0 very sharp over the entire image area of Canon 550D
+ 5.6 aperture to shutter 16 are the ideal conditions for this lens, extremely good sharpness and detail reproduction
+ Excellent color representation over the entire image area
+ Vignettierungskorektur for this Tokina lens is already stored in the camera Canon 550D
+ Internal focusing, therefore ideal for use for polarizing filter suitable (77mm)
Included + lens hood supplied
+ Heavy, stable built lens, acts and is also very high
+ AF sits perfectly and fast enough, you can be in such an extreme focal length eh more time for art work
+ AF / Manual switch solved by pre-push back the front focus ring, I personally feel this is good
+ Except aperture 11 (minimal shading in the corners), this lens also works fully in the EOS 1D Mark II (aperture without shadowing 12-16!)
Conclusion
# Price - performance for this objective very well
# The sharpest and fastest lens in this wide angle
# Absolute buy recommendation from me
