Introduction

If I think about one lens solution or general purpose lens, this lens is an obvious candidate, with the Canon 24-105 is usm. This lens with it’s f2.8 aperture is an obvious candidate for internal photography such as weddings, parties, concerts, etc. The lens’s strong point is consistent results, versatility, build quality, silent focus. The Usm autofocus is silent, but not the quickest compare to lenses such as 135 f/2L or 200/ f2.8L. Compare to a Tamron 17 50 the lens is huge in both dimension and weigth as well. The lens sharpness and contrast are not mind blowing, but consistent through the focal lengths and has nice colours. The lens has not constant physical length, the lens’s shortest state is the longest focal length, see picture above, when is extended that is the widest focal length. In usage point of view the opposite would be logical – zooming from wide to long focal lengths, but perhaps this helps the optical qualities.

Canon 24-70 for weddings

I very much interested about this lens as a potential candidate for a wedding photography. The lens is designed for a Full frame camera, with a sensor size of 36x24mm. I intend to use it on an Aps-C camera where the field of view is 39-112 mm. On a native situation on FF camera this lens has quite wide-moderate telephoto focal length. On APS-C the focal length is not very wide-short telephoto. The longer end of the lens is good for portraits. Let’s check: Portrait at f3.2 with the Canon 24 70 f2.8L USM no post processing, just cropping.


I would say I am very much satisfied with the result. The 70mm is the weakest focal length of the lens, end at f3.2 the portrait is perfect to my eyes. I also made a portrait at f2.8 but the picture were softer either because of focus problem or lens sharpness/contrast capability.

Canon 24-70 sweet spot sharpest aperture

The lens’s sweet spot/sharpest aperture is f5.6 at both end of the focal length.

Canon 24-70 bokeh

The lens’s f2.8 constant aperture helps to create a nice background blur. The below picture are made with an Aps-C camera body (Canon 30D) perhaps the blur is not the same on the FF camera because of different focal length/sensor size situation.

Canon 24-70 f2.8 price/performance

If you can earn money with this lens it has an excellent price/performance ratio, if you cannot the new price of the lens is very high.

Canon 24-70 f2.8 alternatives:

The older 28-70 f2.8, Canon 24-105 f4, the new galactic Canon 24-70 f2.8 II, the Tamron 24-70 Vc. There are many other options. The first two are little worse than the Canon 24-70 Mk I optically, the two at the end much better, but if someone shoot many action perhaps Canon’s af more reliable than Tamron’s.

Canon 24-70 f2.8 Strengths:

F/2.8 bright aperture, decent optical performance at all focal length and apertures, nice bookeh, nice equality, a good lens, but not exceptionally good. Better than the 24-105 though.

Canon 24-70 f2.8 Weeknesses

High price, big and heavy for fun shooting, no stabilizer, zoom ring rotates from tele to wide angle. Autofocus slow compare to it is USM, very slow compare to 24-105.
