Canon 24-70mm f/4 IS USM 'L' lens review with samples (Full-frame & APS-C)


I’ve been holding off covering this particular lens, because before I even tested at it I thought it was overpriced, and I /hate/ overpriced equipment. But, I’ve had a lot of comments from people wanting me to cover it, so I caved in to the pressure and…well, you’ll see what I thought of its quality.

This video includes my new test chart, as I’ve moved to a new place far away from all my old shooting locations. I’ve tried to make it a colourful one.

My Canon 70D had to be sold as I was saving up for my wedding/ honeymoon, so I’m still using my old Canon 60D. It’s kind of falling to pieces by now! All pictures and footage shot by me on Canon 6D and 60D cameras.

  1. My only regret so far with this lens is that I didn't buy it before my last holiday. It's that good compared to all the old second hand gear I've been using. It also works remarkably well with an original EOS650. It is big however. Bigger than the 28-80mm USM it replaces, or the 50mm F1.4 that normally lives in my bag. Balances well on the old beast, mind. Tested it on a 100D for sheds and giggles and it was out-resolving the sensor

    It could read the text on a license plate from 100 metres away in 50mm, which the kit lens with the 100D just rendered as a white.

  2. Hi Christopher, great review – what would you say for price tag of 500 euros.. still bad option for APS-c. or ?

  3. Do you think it is better then the 18-135? The zoom range and price doesn't bother me. ( I can't try both so I need someone's opinion)

  4. Hi Christopher. I bought tamron 24-70 f2.8 . But I gave back. Because of some af issue. And I decided to buy a canon lens. And my budget is not enough for canon 24-70 f2.8. I m thinking about these two lens, 24-70 f4 and 24-105 version 2. The most important thing is sharpness at f4 for me. I watched your 24-105 review and it was really bad about sharpness. even version 2. So what can you say to me about these?I will use it for wedding photography and also "image stabilization" is important for me. Thanks.

  5. If you have to choose between Sigma Art 18-35 f1.8 DC HSM and Canon EF 24-70mm f/4.0L IS USM Lens for Canon 80D, what would you choose and why?
    mainly for portrait, landscape, buildings and just everyday-stuffs.

  6. I have this lens, i love it, but I'm looking for something lighter to replace it. which lens is a good candidate?

  7. Disagree the 24-85 is a horrible lens! Lots of CA, awkward sun-stars but first and foremost very soft corners wider than f11

  8. You didn’t mention the focus shift. Would have been nice to watch a good explanation of this problem not only reading stuff elsewhere I don’t quite understand….

  9. Thanks for the review Chris. I just bought this lens for the 5dIV and paid only 400 pounds for a new one on gray import. I think that is not a bad price for the lens like this. The lens is though not the sharpest but the Light Transmission is better than 24-105 F4 II and I which helps it keep a bit faster shutter speed at the same focal length upto 70mm

  10. Hello Chris, i have a aps c canon760d with sigma comtemporary 17-70mm.
    Wath zoom can i have to get more sharp ?
    Maybe canon 17-40 f4 L ?
    Maybe canon 24-70 L ?
    Or maybe canon 24-105 L ?

  11. It would be nice to see a comprehensive comparison with the 24-105. I was going to buy this lens, but my only concerns are the not super smooth zoom ring and the autofocus noise in video mode. Are those two better or worse on the 24-105?

  12. Good technical review. One thing though: on this and several other reviews comments were made about short focal range. The range actually is perfect for those who own either of the 70-200 mm L lenses. The macro mode also allows one to leave their 100 mm f2.8 L macro at home thus reducing the weight of one's kit. Cheers from Chicago!

  13. I’m looking to invest in a good lens – a multipurpose one. Would you recommend this or something like the 24-105 f4, or perhaps a good one that isn’t an L lens?

  14. Hello Chris. I had this lens for a while and liked it but (like yourself) found myself wanting more. I changed it for the Sigma 24-105mm f4 Art earlier this year and I much prefer the Sigma – I have more fun using it and prefer it's build quality over the Canon, plus I seem to get more consistent results from the Sigma. Great video, like your other lens videos, and all the best!
