The Canon EF 70-200mm f4.0 L USM Lens has to be one of the greatest budget lens you can buy, its so sharp you can cut yourself on the images, every photographer should make this one of their first upgrade in the lens department, the focus ring is smooth to use and the same with the zoom.

The compact RF 70-200mm with f4 and image stabilizer is an expensive but razor-sharp zoom for Canon full-frame cameras.

Small and light, very sharp at all focal lengths, fast autofocus and excellent image stabilization, Weatherproof.

Expensive, can not use stand mount or teleconverter.

While it's a shame that picture and sound quality haven't been upgraded, the iPhone 13 was great in these regards and the iPhone 14 is, too Excellent display Admirable headphone performance Solid build quality No upgrades to picture or sound Familiar design Notch is still present

Apple's latest non-Pro iPhone is superb - it's just that it's strikingly similar to last year's effort.

Still an incredible smartphone, Brilliant battery life gets a bit better, Excellent camera system gets a bit better

Last year’s Pro hardware, Wireless charging slow by modern standards, No USB-C; it’s now well overdue

A major upgrade of Canon’s popular 70-200mm f/4 IS lens, the new Mark II remains relatively compact and lightweight, but packs a heavyweight punch in terms of performance.

Stellar sharpness and contrast, Super-fast autofocus system, 3-mode, 5-stop stabilizer

As pricey as Tamron’s f/2.8 lens, Optional tripod mount ring is expensive

Can the high price be a con too? I did write this as a con and I would leave it if the stabilization was the only difference between the 70-200 f/4L IS and its predecessor. But there is more! The picture resolution is a bit better and the bright light performance is better.

great picture quality in the center and at the edges of the frame, well controlled chromatic aberration, almost absent coma and astigmatism, very small vignetting, small astigmatism, fast, quiet and efficient autofocus, very solid build, high quality build, efficient stabilization

if we try hard to find some flaws, we might say that the performance for f/4.0 and at 70 mm focal length could be a bit better

With built-in image stabilisation and strong image quality, but the widest aperture of f/4 isn’t the best on the market.

The Canon RF 70-200mm F2.8 L IS USM Lens was a game-changer, and the Canon RF 70-200mm F4 L IS USM Lens is the same, taking the game down to a new size and weight low. Those carrying this frequently-needed telephoto zoom lens for extended periods will love this lens's new size and weight.

With the RF 70-200mm f4L, Canon’s once again shown how a new lens can match or exceed the performance of a popular classic while adding something different - in this case a much more compact design, at least when set to 70mm.

Gary Wolstenholme takes a look at how this compact telephoto zoom lens performs. Canon's EF 70-200mm f/4L IS USM costs around £800 and has an Image Stabiliser, silent Ultrasonic focusing with full time manual override and is sealed against dust and moisture.

Excellent optical quality, Superb build quality, Very effective image stabilisation, Fast to focus, Sealed against weather and dust, Light weight

Sometime miss-focuses near minimum focus distance
