Canon EF lenses are the best. This particular lens has great stability, lets in so much light and is light weight compared to the previous version.

I have owned a number of large tele lenses, but the 100-400 stands alone in its combination of outstanding optics whilst staying super light. I know a lot of seasoned wildlife photographers who swear by this lens. Its great value, super sharp and very wieldy.

"I cannot give you a technical review of this lens but from the first moment I used it I could notice an amazing difference. I have owned a series of telephoto lens, the most recent was the Canon EF 70-300mm f/4.5-5.6 DO IS USM.

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

The Canon EF 100-400mm f/4.5-5.6L IS II USM Lens offers professional grade build quality, fast, accurate and quiet AF, very effective image stabilization and very impressive wide open image quality over the entire and very useful 100-400mm telephoto focal length range. Downsides?

For Canon lens fans, the wait finally ended when the company took the wraps off the new EF 100-400mm f/4.5-5.6L IS II USM, a relatively compact super-telephoto zoom that has been hotly anticipated and frequently rumored about for years.

This eagerly awaited telephoto zoom lens replaces the old 100-400mm lens in Canon's lineup of professional lenses. Its predecessor was popular due to its relative compact size, light weight and good value for money.

Is this the best telephoto zoom on the market? Find out in our testing team's Canon EF 100-400mm Mark II review. A 100-400mm lens is a versatile option for shooting faraway sport or wildlife.

I made a series of interferometric measurements showing the lens being diffraction limited at all focal lengths, AND with Kanko 1,4x TC. I am astrophotographer and point light sources are any lenses nightmare. This lens performs up to the fullframe corner.

inredibly sharp at all focal lengths, very good color correction; The best lens I ever saw

a little heavy to carry all day
