Canon EF 100mm is The Best Combination Macro and Medium Telephoto Lens
The Canon EF 100mm f28L Macro IS USM lens is the 1st medium-telephoto macro lens to integrate Hybrid IS, a new Image Stabilizer technology that will optimally compensates for both perspective camera tremble and also shift digicam shake. In addition to a dust and water proof structure for capturing even beneath extreme conditions, the newest lens offers a nine-blade circular aperture for gorgeous, out of focus blurring results for points of light, even during near range capturing.
EF 100mm f 2.8 Macro USM features superb diaphragm:
- Canon finally obtained it right along with NINE blades.
- Round to f/5.6, nonagonal from f/8 on.
- Stops down to f/32.
- Just like al SLR lens, the particular diaphragm is never completely symmetrical at smaller apertures. This really is normal; this is not the LEICA rangefinder lens, which might be about the only lens in whose diaphragms are usually perfectly symmetrical at all apertures.
- The EOS technique doesn't show the truth f/stop as focused more closely. If using a additional light source meter - that isn't really likely - you will need to compensate manually for any natural light reduction as focused more closely.
Canon calls this the CANON MACRO LENS EF 100mm f/2.8L IS USM.
- EF implies "electronic focus," meaning that it has an autofocus motor in the lens itself. All Canon lens since 1987 are already EF.
- L means as expensive as L.
- IS implies Image Stabilization.
- USM indicates Ultra-Sonic Motor, indicating AF is almost silent.
For picture high quality, it definitely significant & very helpful to get the IS for a macro lense. This IS made the big difference between Canon EF 100 f28 Macro with this new Canon EF100mm f28L Macro IS USM lens:
- At the same aperture (let say 3.2); the brand new 100mm 2.8L IS produced better bokeh and much better contrast, colour.
- At low speed (below 1/60) - the brand new 100mm 2.8L IS definitely beat the non-IS.
- A photo at 1/20s using IS enable will be clearer as compared with 1/100s of the older lense (without IS).
It weighs in at about lower than you'd probably earliest expect, that often is a good factor. it's well suited for apply just like a normal purpose telephoto, specifically if you would like close up focus flexibleness. This Canon EF 100 is really a compromise. It's a lens best managed from the area just like a combination macro and as well moderate telephoto.
