With a "II" in the product name, it is only logical that a version "I" of this lens existed and in this case, that lens is the Canon EF 70-300mm f/4-5.6 IS USM Lens . Interesting is that the version "I" lens was itself a replacement of a very similar lens, the Canon EF 75-300mm f/4-5.6 IS USM Lens...

The Canon EF 70-300mm f/4-5.6 IS II USM is a mid-range telephoto zoom lens for Canon's DSLR cameras, incorporating both optical image stabilisation and a new, fast and silent Nano USM motor for autofocus.

Fast autofocus; Up-rated image stabilisation; Build quality; Offers great balance between portability and image quality

Hood costs £75 extra; Lacks a weather seal around lens mount; Highlights can look hard-edged towards the long end of the zoom

Took delivery of this lens today and after a couple of hours wandering along the local canal these are my initial thoughts. Good bits: On my 760D, AF is blisteringly fast and really accurate even in poor light. Much, much faster than the old version and probably faster than my L lenses!

Consistent Output; Easily Interchangeable; Lightweight; Quick Focus; Sharp Focus

"I just bought this lens yesterday and haven't been able to play with it much, but last night I took some pictures of a near full moon without a tripod. When I framed the moon in the lens I could see a lot of movement and shake since I did not support the camera.

I wish I could give the lens 5 stars, unfortunately there was a quality control issue with Canon on the EF 70-300 II IS, there is an internal metallic flake that you can see when the zoom is retracted. I will be returning this lens for a third time, all previous lens have the same issue.

The Canon EF 70–300 mm f/4–5.6 IS II USM, presented in September 2016, is an official successor of the EF 70–300 mm f/4–5.6 IS USM model, launched in 2005. The new lens's optical construction is more complex than that of its predecessor; it also features a bigger filter diameter, a better autofocus,...

Very good image quality in the frame centre; Good image quality on the edge of the APS-C sensor apart from the 70 mm focal length; Slight longitudinal chromatic aberration; Low lateral chromatic aberration; Lack of any serious distortion problems; Low astigmatism; Not bothersome coma; Moderate...

Weak image quality on the edge of the frame at 70 mm; Average performance against bright light; A bit too high vignetting level on full frame

Here we have Canon's new, updated version of their moderately priced 70-300mm full frame lens. It offers improved AF, improved optical quality and a new electronic display. We coupled this to the Canon EOS 5DS R body, so let's see how the lens performs and handles.

The shown price is higher than the MRP.

Despite the fact that the Canon EF 70-300mm f/4.5-5.6 IS II USM lens is not an "L" series lens, it is still capable of producing excellent images. Thanks to its relatively small size and light weight, it would make an ideal companion for photographers who want to have a long telephoto length in...

Another great lens, excellent zoom range on the APS-C camera I have, plus very quiet, and so far nice focusing. Recommended.
