ỐNG KÍNH CANON 24-105

Note: The Canon EF 24-105mm f/4L IS USM Lens has been replaced by the Canon EF 24-105mm f/4L IS II USM Lens.

Boasting the superb build, mechanical và optical chất lượng found in the Canon L-Series Lenses& a widely used range of focal lengths, the Canon EF 24-105milimet f/4L IS USM Lens is one of the best & most popular Canon general purpose lenses made.The 24-105 L Lens quickly became one of my favorite and most-used lenses.If I had only one lens, this would be the one.

One of the most important features in a lens is the focal length or focal length range - get it wrong and you might not be able khổng lồ take the shots you want.And the use for a particular focal length or focal length range varies, of course, depending on theFOVCF of the body being used.That said, this lens gives us a very nice general purpose focal range lớn work with.On a full frame toàn thân, 24mm is very wide.On a 1.6x toàn thân, 24milimet is only moderately wide (equivalent of 38.4mm).And the advantage or disadvantage - whichever it is for you personally - is the opposite on the other kết thúc as well.

Use the mouseover liên kết under the above sầu picture lớn compare the field of view at various focal lengths.The 24-105 L was used on a full frame toàn thân for these shots.A focal length comparison was not on my mind when shooting these pictures, but when reviewing them, I decided you might like lớn see them in this way.The composition jumps around some, but the mountain top can be seen in all of the frames và used as a reference.A B+W MRC Slyên Circular Polarizer Filter was used in these shots.As you can see, the difference between 24mm & 105 is quite large.

When you care about the pictures, you want a well-built lens with great optical quality.The 24-105 L delivers in both of these regards.

As you would expect from an L-Series Lens, the 24-105 L is solidly built.The zoom & focus rings are smooth & the entire lens feels nice & handles even better.I really like the form size và weight of this lens in the field.

Weather sealing seals the khuyễn mãi giảm giá if you are going afield - note that Canon recommends a UV filter for complete weather sealing on this lens.I can"t tell you how much "weather" this lens can take, and don"t condone the practice, but I"ve cleaned my 24-105 L under a gently-flowing kitchen faucet.Do note that this is not a "waterproof" lens.

Looking at the numbers ...The 24-105 is not the lightest/smallest or the heaviest/longest lens in this general purpose zoom lens class.But it is lighter than the 24-70milimet L lens by a noticeable amount.

I find the 77milimet filter size lớn be an asphối.This is not the least expensive sầu filter size, but many of Canon"s better lenses use this size.This makes sharing filters between lenses possible - which has various benefits including cost và travel size/space considerations.

How does this size compare visually?

Pictured above sầu from left to right are theCanon EF 28-135mm f/3.5-5.6 IS USM Lens,Canon EF 17-40mm f/4L USM Lens,Canon EF 24-105milimet f/4L IS USM Lens andCanon EF 24-70milimet f/2.8L USM Lens.The same lenses are pictured below in their fully extended kích cỡ.

Of note is that the 24-70mm L reverse extends - it becomes longest at 24milimet as shown above sầu.Most lenses including the 24-105 L become fully extended at their longest focal length setting and their lens hoods travel along with this extension.

The 24-105 L"s autofocus is driven by Canon"s excellent Ring USM (Ultrasonic Motor).It is internal, fast, quiet - and accurate.The 24-105 L is deemed a parfocal lens -"There"s a cam inside the 24-105milimet lens that is designed khổng lồ maintain an accurate focus when the lens is zoomed from tele towards wide." Though the image remains mostly in focus during focal length change, it is best lớn focus at the desired focal length.

The 24-105 does not extover with focusing và the barrel does not rotate -which makes using circular polarizing & similar rotation-dependant filters much easier.FTM (Full Time Manual) focusing is available.

Good build and mechanical unique does not mean much to lớn a lens without good optical unique to go along with it.In this regard, the Canon EF 24-105milimet f/4L IS USM Lens ranks at the top.

The Canon EF 24-105milimet f/4L IS USM Lens is quite sharp wide open và shows only very slight improvement when stopped down.Corner sharpness is very good - Full frame DSLR users will see some softness in the far corners at the wider focal lengths until stopped down.

As with most lenses, full frame users will also see some light fall-off with the 24-105 L wide open - especially at the far corners at the widest focal lengths.The light fall-off quickly improves as the lens is stopped down.Reduced field of view Digital SLRs will avoid most of this effect.I see varying amounts of physical vignetting at 24milimet when using a standard thickness circular polarizer filter -I recommover using a sllặng circular polarizer filter for this lens.

Also comtháng with lenses in this focal length range is distortion.The 24-105 L shows noticeable barrel distortion from 24mm until disappearing near 40mm.Pincushion distortion begins at 80mm và becomes mild at 105milimet.As usual, this distortion is most noticeable of a full-frame body.

Flare? Well, flare is very well controlled with one exception.In very early models of this lens, a very bright point-light source positioned precisely in the corner of a full frame viewfinder with the lens phối to 24milimet and not stopped down muchwill result in often beautiful but generally not wanted rays of flare.The rays gets smaller as the lens is stopped down.The rays fade away as the focal length is increased until completely disappearing at 35milimet or so.

Canon has posted a Service Notice acknowledging the flare problem & will repair any affected lenses (a Canon date code/control number less than UT1000) at no charge (including shipping).Be aware of this issue if buying an old used lens as it may or may not have been repaired.

The above sầu picture attempts to show the maximum rays-of-light flare I could produce at the tested focal lengths và apertures.I was shooting inkhổng lồ a very bright spot light positioned just inlớn the frame.The rays disappear by 35mm.I eventually sent my 24-105 L to lớn Canon for repair - they promptly replaced the lens with a new one.The new copy does not exhibit the rays-of-light flare issue & works excellently.

The 24-105 L"s color and contrast are excellent.The rectangular baffle (above) over the rear of the lens is purposed khổng lồ increase contrast and reduce flare/ghosting.CA (Chromatic Aberration) is overall well controlled, but expect khổng lồ see some CA in areas of harsh contrast toward full-frame borders at both ends of the focal length range.

The 24-105 L features a reasonably fast widest aperture setting of f/4 which remains constant throughout the zoom range.This lens rounds out Canon"s f/4 zoom lens line - Up to 200mm at least(many of us would lượt thích to see a Canon"s f/4 zoom lens line extended to lớn include an EF 200-400mm f/4L IS USM Lens).

Eight circular aperture blades provide excellent quality defocused image unique (bokeh - foreground/background blur).While f/4 in this focal length range is not the best at creating diffusely blurred backgrounds,cchiến bại subjects at 105mm can have pleasingly blurred backgrounds.

Canon"s lakiểm tra generation Image Stabilizer (IS) provides an additional 3-stops of handholdability in the 24-105 L.This is definitely one of my favorite features of the 24-105 L.The 24-105 L"s IS is very quiet và very well behaved (does not jump when starting, ...).IS does not stop subject motion blur, but it is excellent for stopping camera shake.IS allows use of narrower aperture settings khổng lồ increase DOF (Depth of Field) in handheld shots with non-moving subjects(landscapes, sculptures, art ...).IS allows use of longer shutter speeds lớn create motion blurs - such as moving water.Or simply shoot handheld in low light levels with the lens wide open using IS khổng lồ steady the shot.

Theoretically, IS enables this lens can be shot handheld at shutter speeds as low as 1/3 second at 24mm on a full frame body toàn thân.Your results will depover on how steady you are, but I am seeing sharp shots at 1/3 second (& many longer) at 24mm& 1/6 second (and longer) at 105milimet.Very nice.A tripod was not used for most of the 24-105milimet sample pictures (liên kết below) with shutter speeds below 1 second.I would unscientifically rate this lens as delivering a keeper rate as high or higher than any lens I own or have sầu owned.And most of my throw-aways are the fault the person behind the lens.

Also very nice are the recessed switches for IS (on/off) & AF/MF (Autofocus/Manual Focus) as shown above sầu.Canon"s previous switches are nice, but raised và susceptible khổng lồ being accidentally changed lớn a different setting.I have sầu missed shots on occasion because I inadvertently turned IS off on other lenses.Although still easy lớn use, the recessed switches should eliminate this problem.

The Canon EF 24-105milimet f/4L IS USM Lens" short MFD (Minimum Focus Distance) provides for a very reasonable MM (Maximum Magnification).While not cđại bại to a 1:1 macro lens, the 24-105 L can take nice flower shots, hàng hóa pictures ...Although it is not compatible with Canon"s extenders,extension tubes will extover the 24-105 L"s macro capabilities.Canon makes a 12milimet extension tube and a 25milimet extension tube.The Canon 500D is a close-up lens that attaches lớn the filter threads - it also allows closer focusing distances.

The 24-105 L ships with a Canon EW-83H lens hood và a Canon Lens Soft Pouch.If you want a more-protective case, the Lowepro Lens Case 4S is a good choice.It will hold the 24-105 L with its hood in place.

Prior to lớn the introduction of the 24-105 L, the Canon EF 24-70milimet f/2.8L Lenswas unquestionably (in my mind at least) the best general purpose Canon zoom lens available.The 24-105 L now shares this designation.Both lenses are excellent - và they complement each other well.

Since many people cannot afford both of these great lenses, a decision needs khổng lồ be made between them.And requests for help with this decision may perhaps be the greathử nghiệm single reason for gmail khổng lồ be sent khổng lồ me.I"ve given my request to lớn Canon (not saying I have any leverage) for a 24-70mm f/2.8L IS USM Lens, but until they introduce such a lens, this decision will continue khổng lồ be made.So, let me see if I can help.

The 24-70mm f/2.8L Lens" big advantage is its wider constant aperture.Going from f/4 to lớn f/2.8 makes a big difference.This 1 stop change in aperture is equal to allowing twice as much light through the lens.And this of course yields a shutter tốc độ that is twice as fast at the same ISO setting.When you need to stop action (people are rarely motionless) - especially in low light, the 24-70 L holds a big advantage.

The wider aperture also creates a more diffusely blurred background at similar focal lengths due to shallower DOF (Depth of Field).However, the longer focal length on the 24-105 L creates more background blur at 105mm & f/4 (from compression) than at 70milimet & f/2.8 - so there is some leveling in this differentiator.Possibly more important is the ability of some camera bodies to lớn focus more accurately with f/2.8 and wider aperture lenses.A somewhat brighter viewfinder accompanies wider aperture lenses.

The Canon EF 24-105milimet f/4L IS USM Lens" big advantage is the 3-stop IS.IS will dramatically help reduce camera shake-caused blur when shooting handheld at slow shutter speeds.The 24-105 can be handheld in about 1/4 the light levels required for the 24-70 to lớn be handheld in as long as the subject is still.IS cannot stop subject motion.

The extra 35mm of focal length on the long over of the range is a nice advantage of the 24-105 L.You can get an idea of what this difference looks like in the focal length comparison above sầu.This additional focal length is especially nice for portraits on a full-frame toàn thân.At short distances, the 24-105 L at 24milimet is wider than the 24-70 L at 24mm (lenses are rated at infinity but subject framing can vary at cthua kém focus distances).

The Canon EF 24-105mm f/4L IS USM Lens, as you likely saw earlier in this Review, has a nice kích cỡ và weight advantage over the 24-70 L - .7" (16.5 mm) shorter và .6 lb (280g) lighter.And the 24-105 L lens hood is much smaller as can be seen in the picture below.

Pictured above from left to right with their respective lens hoods in place are theCanon EF 17-40milimet f/4L USM Lens,Canon EF 24-105milimet f/4L IS USM Lens andCanon EF 24-70mm f/2.8L USM Lens.As mentioned before, the 24-105 L"s hood extends with the lens (most lenses behave this way) while the much larger 24-70 L hood stays in one place.The 24-70 L extends inside the hood - the overall kích thước of the 24-105 with the hood in place changes while the 24-70 L stays the same length.Because the 24-70 L lens hood is in a fixed position (it does not extend/retract), the objective sầu lens retracts deeper inlớn the hood as the focal length is increased.In other words, the 24-70 L lens hood extends much farther from the objective element of the lens at 70mm than at 24milimet.The 24-70 L is using an appropriate-for-the-selected-focal-length lens hood at all focal lengths while the 24-105 is using a made-for-24milimet hood at all focal lengths (like most lenses).

As you saw in the chart above sầu, the 24-70 L focuses closer (1.25"/0.38 m vs. 1.7"/0.45 m) and yields a higher maximum magnification (.29x vs. .23x).

Price, build chất lượng and image unique differences will likely not affect the purchase decision of many.Both lenses are very sharp.Both lenses have sầu good color và contrast.The 24-105 L has less light fall-off wide open than does the 24-70 L wide open, but the 24-70 has a slight advantage at comparable apertures.The 24-105 L has slightly less CA than the 24-70 L.Both are very good in this regard only showing CA in harsh situations at their widest focal lengths.

The 24-105 L is shown above mounted on a Canon EOS 5D Mark II.

I am sure that many Canon EF 24-70mm f/2.8L Lens owners will also have a 24-105mm L in their kit.Indoor event photographers will *probably* select the 24-70 L while landscape/outdoor, travel and portrait photographers might prefer the 24-105 L.

Since this Đánh Giá was written, Canon has introduced two additional lenses very deserving of your consideration - theCanon EF 24-70milimet f/2.8L II USM Lens và theCanon EF 24-70milimet f/4L IS USM Lens.Chechồng out those đánh giá to get the complete picture.

For my personal uses in this focal length range, the Canon EF 24-105milimet f/4L IS USM Lens is on my camera more than the 24-70 L (now 24-70 L II).If your needs are for wider focal lengths & you are using a 1.6x FOVCF body toàn thân, you should also consider theCanon EF-S 17-55milimet f/2.8 IS USM Lens.It is another excellent choice.
