Lens Description: Designed to exceed expectations and ideal for video and still images alike, the new EF-S 18-135mm f/3.5-5.6 IS STM marks a new standard for EF-S lenses. It features a refined Image Stabilization system that delivers up to four equivalent stops of shake correction throughout the zoom range; and offers a maximum magnification of 0.28x at the telephoto end, while remaining even more compact in size. This EF-S lens supports the Canon EOS Rebel T4i DSLR\'s Movie Servo AF feature for smooth and quiet continuous AF during movie shooting by utilizing a new six-group zoom system and the adoption of a stepping motor and focus mechanism. High-speed autofocus is achieved thanks to an Inner focusing system, high-speed CPU, and optimized AF algorithm. Appearing for the first time in a Canon lens is Dynamic IS (Movie Shooting Mode only) that uses a wide image stabilization correction range to help ensure steady video while shooting when walking.Whether shooting movies or stills, image quality is phenomenal, with one UD and one PMo aspheric lens providing high resolution and high contrast images with reduced chromatic aberration throughout the zoom range. A 7 blade, circular aperture ensures beautiful, soft backgrounds and optimized lens coatings ensure excellent color with minimized ghosting and flare. A zoom ring lock even prevents the lens from accidently extending

I initially bought the Tamron 28 – 300 (I think) and sent it back, as, for the first time ever, I thought a Tamron lens was rubbish – I have several Tamrons and love them usually, especially my 70-200mm f2.8 and my 90mm macro lens.
So, I contacted Wex Photographic (where I’d bought it) who were brilliant and allowed me to exchange it for this Canon 18-135 and what a brilliant lens it is. It is sharp across the entire focal range (I shot a photograph of a CD on a bush from about 100ft away and could read every word on it! Clearly!!!
I love this lens and it has now usurped my 28-75 f2.8 Tamron as my new eveeryday favourite!
I shall be trying it out on concert photography this week and know I am going to get great shots. The photos are vivid, sharp and unusually for zooms, there is very little distortion.
