What is a Canon EF 24-105mm f/4L IS II USM?
When Canon announced a EOS 5D Mark IV final year, it arrived on a stage during a same time as dual new full-frame optics: a EF 16-35mm f/2.8L III USM, and a revamped EF 24-105mm f/4L IS II USM.
Both lenses play a pivotal purpose in Canon’s EF full-frame lineup. However, it’s a EF 24-105mm f/4L IS USM that’s some-more versatile and is expected to be a bigger seller formed on a fact that a lens it replaces has been one of Canon’s best-selling full-frame optics for a past 10 years.
The strange EF 24-105mm f/4L USM has been a renouned lens with Canon users for many opposite reasons. For those creation a burst from an APS-C DSLR to full frame, it’s seen as one of a best multi-purpose lenses we can buy, and there’s mostly an inducement to buy it with a new DSLR as partial of a pack and save a substantial sum of income in a process.
What’s more, when we take a L-series standing into consideration, we know that it’s been engineered to Canon’s high standards and advantages from a form of build peculiarity that will see it tarry visit and perfectionist use over many years.

Canon EF 24-105mm f/4L IS II USM – Features
Favoured by those wanting to lift a singular lens on location, a EF 24-105mm f/4L IS II USM falls into a customary wizz stay of reward lenses and differs from a strange EF 24-105mm f/4L IS USM in a series of ways.
I’ll hold on a approach it’s built to withstand a final of veteran use, with extended insurgency to startle and quivering shortly, though let’s initial outline what else is new.
The lens facilities a revised visual pattern compared to a predecessor, that Canon claims improves fortitude and edge-to-edge sharpness around a frame. Where a strange lens featured an visual pattern of 18 elements in 13 groups with 8 orifice blades, this newer lens incorporates 17 elements in 12 groups with 10 orifice blades.
You’d consider that this would revoke a weight of a lens a little, though it’s indeed somewhat incomparable and heavier than a predecessor.
Modifying a visual construction has seen a limit magnification boost somewhat from 0.23x (at 105mm) to 0.24x (at 105mm). However, there’s no change to a smallest focusing distance, that stays during 0.45m.
Elsewhere, a lens facilities Canon’s latest visual picture stabilizer, that is privately designed to negate fuzz effects that are ordinarily compared with camera shake. The good news here is that a picture stabilizer is now effective to 4 stops rather than 2.5, creation it probable to grasp crook handheld shots during slower shutters speeds.
Unlike many cheaper customary zooms, a limit orifice stays during a consistent f/4 right by a wizz range, though can be stopped down to a smallest of f/22.
In customary Canon fashion, a lens uses an ultrasonic engine to safeguard autofocus is both quick and quiet. The full-time manual-focusing ring allows users to make excellent focusing adjustments on a fly, though carrying to switch to primer mode first.
Canon has also ensured a lens provides smoother orifice changes during film capture, by implementing a new electronic orifice diaphragm complement (EDM).
As you’d pattern for a lens that’s set to turn a customary go-to choice for many veteran and fan photographers, it includes continue sealing to forestall users carrying to reserve it divided in inauspicious continue conditions.
At a back of a lens there’s a rubber ring that compresses and effectively seals it opposite a camera’s steel lens mount.
Towards a front of a lens you’ll notice a famous red ring that’s synonymous with Canon’s reward L-series optics, and it accepts filters and adapter rings around a 77mm thread usually like a precursor.
Canon EF 24-105mm f/4L IS II USM – Build and handling
As already quickly mentioned, a EF 24-105mm f/4L IS II USM is heavier than a lens it sets out to replace. Not usually does it import 125g more, it’s physically larger.
The disproportion in length is many apparent when it’s noticed side by side with a original, and by being that tiny bit longer (11mm to be precise) it has authorised Canon to make a wizz and concentration rings larger.
I didn’t confront any difficultly locating or differentiating one ring from another from behind a camera on a comparison lens, though with this newer ocular we do get somewhat improved squeeze of them both.
The wizz ring operates opposite a focal operation with a consistently well-spoken motion, and it never feels like you’re compulsory to put some-more force into rotating it during one indicate than another.
When it’s used during a telephoto end, a front of a lens extends by approximately 40mm, though continues to feel good offset with full support DSLRs such as a EOS 5D Mark IV with that we tested it.
There’s zero to forestall it being joined to a Canon APS-C DSLR (equivalent to a 38-168mm lens). However, on smaller bodies such as a EOS 77D, it does make a camera feel utterly nose-heavy and not as good balanced.
During a revamping process, Canon has updated a outmost pattern of a lens to compare a demeanour of other stream L-series zooms such as a EF 24-70mm f/2.8L II USM. In a past, it’s always been sincerely easy to tell a strange 24-105mm lens detached from Canon’s latest 24-70mm quick orifice zoom; they now demeanour really similar.
When it’s compared directly with a predecessor, you’ll notice utterly a few tiny differences such as a focal length markings being closer to a physique of a lens, bolder white lettering, and a dismissal of a name of a lens during a front of a barrel, that is now printed beside a front element.
The pattern and position of a AF/MF and stabilizer switches stays most a same during a side, though given a stabilizer switch was somewhat recessed on a comparison version, it isn’t on this newer version.
The primer concentration ring provides a really liquid and appreciative feel in use, and altogether a lens meets a flawless build peculiarity that one would pattern from Canon and a lens that breaks a four-figure cost barrier. You even get a close switch to forestall a wizz fluctuating over 24mm – though we frequency used it, given there was no pointer of a wizz wanting to climb when it was indicating down.
Although a lens is concordant with a comparison EW-83H lens hood, users are suggested to use a granted EW-83M hood, that now thatch into place to forestall it from being incidentally knocked off; it requires we to subdue a tiny symbol to recover it. Within a boxed essence we also get Canon’s latest character of lens top and a compress lens pouch.
Canon EF 24-105mm f/4L IS II USM – Autofocus
Testing this new lens alongside a aged suggested that it’s incompletely quieter when it goes about a business of focusing – however, it isn’t wordless to a indicate that it manners out operational focusing noises being picked adult by a built-in microphone during film recording.
As for autofocus speed, we didn’t knowledge an apparent alleviation between new and old, with any lens clearly focusing as quick as a other between nearby and distant subjects.
However, what is an alleviation is a approach a orifice can now be practiced silently during film recording, statute out a annoying clicking sound we used to get on a comparison lens as a orifice blades moved.
