One of the most agonizing lens decisions that Canon users often face is the choice between the 24-70mm f/2.8L and the 24-105mm f/4L IS. Those who have to choose between these two lenses usually waiver back and forth between the benefits of the IS and extra reach of the 24-105mm versus the f/2.8 aperture of the 24-70mm and many find it hard to come to a final decision. If you are faced with this choice then this article will definitely help you with your decision.

Canon 24-70mm f/2.8L vs Canon 24-105mm f/4L IS
Both the 24-70mm and the 24-105mm are L-series lenses that produce very high quality pictures, so the primary deciding factor in this case is what you intend using the lens for and to a lesser extent what type of kit you already have. So let’s take a look at some of the important things to consider in this debate.
Canon 24-105mm IS vs Canon 24-70mm f/2.8 Aperture
This is certainly one of the most debated points when it comes to these two lenses. The IS adds up to 3 stops advantage and is great for reducing camera shake in low light, but it won’t freeze motion. To do that you need fast shutter speed and to get fast shutter speed in low light conditions you need wide aperture. This is an important consideration if you plan to shoot at events like weddings where you frequently want to freeze the action to capture moments like the toast, throwing of the boquet etc. The f/2.8 aperture of the Canon 24-70mm allows you to shoot at shutter speeds where you shouldn’t have to worry too much about camera shake, which is probably one of the reasons why this lens is not equiped with IS. So in the IS versus f/2.8 debate, my vote goes to the 24-70mm f/2.8L .
The Extra Reach of the Canon 24-105mm f/4L Lens
When looking at focal length it is important to consider other lenses you plan to purchase or already have. Canon’s 70-200mm L lenses for example are incredibly popular and if you already own or plan to purchase any of the four 70-200mm models in the future, the 24-70mm will be the perfect compliment to complete your set. This will give you L-series quality all the way from 24mm to 200mm and if you have the 70-200mm f/2.8 you will have wide aperture across this entire range of focal lengths. In general, if you plan to buy any mid-range zoom lens, the 24-70mm is probably a better option than the 24-105mm.
On the other hand, if you don’t plan to get additional zoom lenses, the 24-105mm could be a better choice because of the extra range it provides. Many people don’t like switching between lenses and just want one L-series lens that provides a lot of versatility with someĀ zoom and the benefit of Image Stabilization . In this case the 24-105mm offers great value.
Conclusion – The 24-70mm f/2.8L vs the 24-105mm f/4L IS
If you plan to own just one L-series lens and you are looking for the ultimate walkabout lens that takes professional quality photos, with a fairly wide zoom range and the added benefit of Imaze Stabilization, then the 24-105mm is the way to go. However, if you plan to own multiple lenses (especially mid range zoom lenses like the 70-200mm range) or if you plan to shoot indoor events like weddings in low light conditions, the 24-70mm f/2.8L is definitely the way to go. Never underestimate the benefit of the wide aperture, it is one of the most important features that professionals look for in a lens.
