Verified Purchase(What is this?)
This review is from: Sigma 18-250mm f/3.5-6.3 DC Macro OS HSM Lens for Canon (Electronics)
I was previously using the Canon 18- 135 lens which was good but I am a believer in technology, new models and new designs usually are better than older ones. Lens manufacturers are constantly trying to improve their products. I decided to give this lens a test, and I am glad I did. It is light but feels exceedingly well made (in Japan). I have been testing it on a Canon 550D. My copy has no lens creep so I don't need the lock button engaged. Perhaps Sigma have addressed this. What is outstanding is the image quality, which for most purposes is nearly perfect. Good contrast, good colour, little distortion even at wide angle and a great range of focal lengths. The autofocus is very fast indeed. The macro facility is excellent I bought the lens from Amazon, and for this type of universal lens I don't believe at the current time there is a better competitor, and it balances beautifully on the 550D. I am exceedingly pleased with it.
