Canon EF 24-70mm F/4L IS USM Lens

December 4, 2012

Canon updated its EF lens lineup with the Canon EF 24-70mm f/4 L IS USM lens.  This lens will be very popular among amateurs and enthusiast photographers due do its relatively lower price tag compare to the f2.8L version which costs around $2100. This is also the perfect match for the 70-200mm f4L IS lens. Some photographers might still debate between a f/2.8 and f/4 lens,  but no doubt that this lens will be a very popular one in the enthusiast market.  This is also a compact lens that comes with 4-stop image stabilization.

The Canon EF 24-70mm f4L IS USM comes with some very useful functionality, including:

  • Canon’s Hybrid IS optical image stabilization (up to 4-stops)
  • Weather sealing (dist and splash proof)
  • Constant F4
  • 0.7x magnification in Macro mode
  • Ultrasonic Motor for fast and silent auto-focusing system
  • Full time manual focus
  • 9 rounded diaphragm blades
  • Internal focusing mechanism
  • ‘fluorine’ fingerprint-resistant front element
  • Two aspherical and two UD lens elements

On in all, the new 24-70 F4L IS certainly boasts some very attractive features.  This is a type of lenses that every enthusiast would love to have in his camera bag.

As you can see from the above image from camera size lens comparison that this lens is indeed a compact lens. You can see that it beautifully fits the size of the Canon EOS 6D which is mounted on.


For comparison:

24-105mm f/4: 84mm x 107mm
24-70mm f/4: 83mm x 93mm
24-70mm f/2.8 II: 89mm x 113mm

The 24-70mm f/2.8 II doesn’t include an image stabilization feature, and this will certainly come into aid when shooting in low light, as this lens is twice less bright than the f/2.8 model. This is also the same Hybrid IS used with the 100mm f/2.8L IS USM Macro lens. So although not a 1:1 macro lens, this lens has useful macro capabilities and therefore the Hybrid IS is a very useful feature in this regard.

Canon 24-70mm f4L IS USM is optimized for 35mm cameras but of course is compatible with all Canon APS-C and APS-H digital SLR cameras.

Many of you might compare this lens to the popular 24-105mm F4 L IS lens. The 24-70 is more compact, improved on the zooming mechanism, reduces size and weight. The 24-105 offers longer reach and of course it offers a constant f2.8 lens. It’s twice as bright and therefore offers two main advantage: better low-light capabilities, more shallower depth of field.

For Macro shooting, the 24-105 offers 0.23x magnification versus the impressive 0.7x magnification of the 24-70 mm. This makes the 24-70 F4L IS a very versatile lens. Of course if you are into shooting Macro, just get the 100mm F2.8 L IS lens, which will give you 1:1 macro and longer reach, and all in all, a much better lens for macro photography.


Introduction Video from WhatDigitalCamera:


The video makes an important note about how the lens fit to today’s latest digital cameras. The latest generation DSLR cameras are capable of shooting high quality images at very high ISO sensitivity. This means that even with a F4 aperture, you still be able to take sharp and well exposed images in low light. This is also very true to full frame DSLR cameras. So in terms of low light performance, the difference between F4 and F2.8 becomes less of an issue. Of course F2.8 will still provide a better low light performance, but shooting with an F4 lens and higher ISO can give you very good results nevertheless.

The Canon EF 24-70mm F/4L IS USM as a wish come true to enthusiast photographers on a budget. Those of you who cannot afford the F2.8 version, now have a good alternative. I really likes the size of this lens, makes is a perfect lens for the Canon EOS 6D. Some of you who were tempted to get the 6D but don’t have budget for the F2.8, you will be happy to have a lens like the 24-70 F4L IS. It’s small, lightweight and built with very high standards. The performance of this lens in terms of resolution and low distortions will perfectly match high resolution sensors. The nine-bladed aperture will give you soft buttery-smooth Bokeh, which makes this lens also a good portrait lens, but also a good lens for landscape shots when mounted on a  full frame camera like the Canon 6D.

We can clearly see that Canon is working hard to keep the enthusiast crowed satisfied. As more people on the lower-end move to mirrorless cameras, there is more need to give enthusiast photographers exactly what they need.  The 24-70mm will compliment the 70-200mm F4 L IS both in terms of focal length range and optical performance.  No doubt that this lens should be on top of your list, especially if you are into buying the Canon EOS 6D DSLR.
