Mount: Canon | Construction: 13 elements in 10 groups, 8 diaphragm blades | Closest focus distance: 25cm | Filter thread: 77mm | Autofocus: ring-type ultrasonic | Dimensions: 80 x 87mm, 650g This is the mark II edition of this lens and isn't just a minor tweak but represents a complete redesign.

This is the mark II edition of this lens and isn't just a minor tweak but represents a complete redesign. It boasts an extra two elements, taking the total number from 11 to 13, and its more rounded aperture is based on eight rather than seven diaphragm blades.

Quality metal construction; Ring-type autofocus; Wide maximum aperture

Disappointing sharpness; Expensive; Vignetting (corner shading) at maximum aperture

Amazing piece of glass, sharp and light. I have canon 24-70mm and it's defiantly a great replacement.

This here is the BEST 24mm you will find in the world. Having a maximum aperture of 1.4 is VERY useful in low light and great for subject isolation. My only problem is that it had a bit of a front focus problem but I sent that to Canon for recalibration free of charge.

Durable; Fast / accurate auto-focus; Nice Bokeh; Strong Construction

It is great price and its small and light so can easily fit in my camera case for portability.

Its a good lens; fast focus with 50mm; inexpensive and produces sharp pictures

Feels a bit plastic and cheap

I bought this for indoor ambient light shooting and it's a great lens for that.

When I first picked up photography, I have always wondered on the viability of spending large amounts of money for a fixed focal prime lens such as this. However, having cycled through quite a few Canon lenses and 'L' series lenses ranging from zoom lenses and other primes, I have arrived in front...

Very wide aperture for taking indoor photos without a flash - Paper thin depth of field at F1.4 provides capability to produce dramatic shots while still capturing much of the background to 'tell the story' - Good quality construction - Price range defini

- Focusing speed a tad slow (but not enough to affect me on wedding photography

Gary Wolstenholme reviews the premium fast wide-angle Canon EF 24mm f/1.4L II USM lens.

Excellent optical performance; Build quality; Fast focusing; Bright maximum aperture; Resistance to flare and loss of contrast

May be a little pricey for some; Quality towards the edges at maximum aperture could be better (although this is a minor concern for a wide aperture lens like this)

The two large-diameter, glass-moulded aspherical elements correct aberrations like curvature of field and distortion, both common in wide-angle lenses. In addition, two UD elements are used to minimise chromatic aberrations.
