REVIEW – CANON RF 100-400 LENS

RF 100-400 f5.6-8 IS USM ❤️❤️❤️❤️❤️
Canon 100-400

The Canon RF 100-400 f5.6-8 IS USM lens , is a lightweight , full function RF mount zoom lens aimed primarily at hobbyists and enthusiasts and promises to deliver stunning images of wildlife. As well as being affordable and compact which should make for a portable easy to use option suited to both close-up and distance photography. Compared to it’s big brother the L series 100-500 it certainly delivers on portability , weighing in at 635g compare to 1530g so obviously a massive saving in weight. Add in 5.5 stop optical image stabilisation and you have a lens you can comfortably hand hold all day.

The lens uses a Nano USM motor delivering near silent and fast auto focus together with the now standard Lens Control Ring giving you more control over camera functions when on the move. I have been using this lens on my second body and it certainly is quick and very easy to use , plus at only 165mm long , it’s also compact enough to fit into my camera bag with two bodies and two lenses , a real bonus.

The lens controls are well laid out and configured, as well as the Lens Control Ring there’s a selection switch for manual and and focus , control switch to select image stabilisation and finally a lens lock switch , always hand when transporting the lens to stop lens creep. One noticeable absence is a tripod thread , probably not a deal breaker because I’m guessing most users will hand hold , however at the price point I would have expected the lens to have one.

As with most of Canons RF STM lenses the hood isn’t included and if you opt to add this from Canon it comes at a considerable extra cost . However I’m splitting hairs here a little bit because for the money this is a cracking good lens. In the time I have been testing the lens it has outperformed my expectations and the quality of images is pretty good . Despite it’s lightweight construction the lens has proved to be a robust and well manufactured piece of equipment, even surviving a tumble down a flight of concrete stairs with only a few minor scuff marks to the lens hood !

If you love to photograph animals, it’s an ideal lens. I noticed how the minimum focus distance of 88 centimeters at 400mm works perfectly for semi-macro. It allows a maximum magnification of 0.41x, ideal for flowers and insects

So the million dollar question , should you buy one ? If you want a portable lightweight small lens with 400mm reach for wildlife photography then this is definitely the right solution. Easy to use , super responsive auto focus, economically priced , robust construction and delivering surprisingly good results the answer is a definitive yes and it’s now a staple part of my kitbag.

  1. I have this lens. Love the weight and picture quality. The only thing that can be problematic is noise when I have to use a higher ISO at 400mm however Topaz noise does a good job of dealing with it
