Canon EF 100mm F2.8 USM Macro Specifications Review

The EF 100mm F2.8 L IS USM Macro connects The canon eos amazing short-telephoto collection as a complement to (rather than a alternative for) the current EF 100mm F2.8 USM Macro, and at a lot high price. Together with technical innovation IS technical innovation it benefits all the typical benefits associated with the top quality ‘L’ logo, such as effective, weathersealed build and the use of unique cup for the modification of aberrations. The visual growth is of 15 components in 12 categories, along with a single ultra-low distribution cup factor, and the 1:1 highest possible zoom is obtained at a lowest concentrate range of 0.3m.

Canon makes some quite specific statements for the efficiency of its new IS program, and it’s worth looking at these in details. The backing is predicted to give a 4 stop advantage at longer concentrate ranges, losing to 3 prevents at 0.5x zoom and 2 prevents at complete 1x zoom. The first of these specifications is pretty much par for the course for The canon eos current IS contact contacts, but even with the Multiple program it’s clear that the level of stabilizing at near ranges is predicted to be relatively low (this despite The canon eos advertising content declaring that it ‘enables photography lovers to catch amazing close-up photos without the need for a tripod’). So the question audience will certainly be asking is whether the combination of functions provided by the new lens is completely powerful to warrant buying it over the older, but well-regarded non-stabilized 100mm macro.

Headline features

  • 100mm set central length; F2.8 highest possible aperture
  • Macro focusing: 1:1 highest possible magnification
  • ‘Hybrid’ picture stabilizing program for improved efficiency at near concentrate distances
  • Canon EF install for full-frame and APS-C DSLRs

Canon EF 100mm F2.8 L IS USM Macro Body And Design

The 100mm macro is a reasonably large lens, and its development and styles will look immediately acquainted to anyone qualified in The canon eos latest ‘L’ sequence styles. The outside of the gun barrel is made from top quality nasty, which will help maintain weight down, and the install is of course metal; there’s also wetness and mud closing (with a safety closure around the lens mount). All-in-all it seems completely well-built, with no creaks or ‘give’ to the construction; but in fact little different from its non-L unstabilized brother (aside from the closing of course).

The manages are well laid-out and obvious – the three control changes on the side are beneficial yet difficult to affect unintentionally, and the concentrate band is wide and sleek operating. The simply round area close to the install is the connection point for the optionally available Tripod Mount Ring D.

Lens body elements

  • The lens uses Canon all-electronic EF install. This implies it will fit all of The canon eos DSLRs regardless of indicator structure, APS-C, APS-H or Negatives full-frame. It can also be used with The canon eos expansion pipes for even higher zoom. A rubberized closure around the outside of the install defends dirt and water ingress.
  • The narrow line is 67mm (as used on the 70-200mm F4 L models), and does not move on concentrating.
  • The provided ET-73 lens bonnet is seriously wide – a complete 83mm in detail, to be accurate. This is so deep that, at 1:1 zoom, it’s just 5cm from the topic. As always from Canon it’s made of dense black plastic material, and covered with experienced to reduce the representation of wander light into the lens. It turns around for storage, but in the process prevents the main concentrate band and all of the management changes.

  • This can make accomplishing really accurate guide concentrate the ‘portrait range’ (ca. 1 – 3m) just a little challenging.

Canon EF 100mm F2.8 L IS USM Macro Test Results


The lens is very distinct start up, with just a small fall off towards the sides. Best answers are seen in the F4 – F5.6 variety, at which factor the calculated sharpness is likely to be restricted mainly by the 50D’s relatively competitive visual low-pass narrow. Diffraction gradually decreases sharpness on avoiding down further, with apertures more compact compared to F16 providing incredibly smooth outcomes.


We consider falloff to start becoming recognizable when the area lighting drops to more than 1 quit below the middle. As always for a full-frame lens on APS-C, falloff is minimal.

Macro Focus

The 100mm gives real 1:1 macro, which shows a lot of information on a higher quality APS-C indicator. Main sharpness is very great even at F2.8, with the sides just a little behind. Maximum outcomes are seen around F8; apertures of F16 and more compact certainly begin to experience poorly from diffraction, and should probably be ignored unless excessive details of area is needed (F32 is very smooth indeed). There’s a minor sign of red/cyan fringing from horizontal chromatic aberration towards the sides, but you’re unlikely to see it outside of doing duplicate work.


Like many contacts with a relatively filter position of perspective, the 100mm Macro isn’t at all satisfied when shiny mild resources are straight in taken – then again you will not find that many images you’d want to take with it where this happens (sunsets maybe). The answers are not fairly at any aperture, but as regular various colored surface styles become ever more noticeable the further you quit down.

Shoot with the sun just a little bit out of the structure and although surface can continue to persist, it’s much less challenging. Overall though, given the complexness of the lens’s development and the revealed characteristics of the top side factor, we’d suggest (even more than usual) using the bonnet in shiny mild as just a few course.

Bokeh Quality

One truly suitable, but hard to evaluate part of a lens’s efficiency is the capability to provide efficiently blurry out-of-focus areas when trying to separate a topic from the qualifications, usually when using a lengthy central duration and huge aperture. The 100mm F2.8 macro is able to provide significant qualifications cloud, although image photographers should observe that officially it merely can’t coordinate its brief telephoto stablemates, the EF 85mm F1.2 L II USM and 135mm F2 L USM.

In common, bokeh is incredibly pleasant; at macro ranges it is, as we might anticipate, incredibly sleek and ‘creamy’. It’s not quite the best you’ll ever see, but it’s very awesome indeed.
