canon 180 macro test

The 180/3.5 is optical and mechanical perfection for use as a telephoto, portrait, nature and landscape lens, as well as being Canon's best macro lens ever.Autofocus isn't very good; because of the huge range of focus distances covered by this lens, if you're not already in about the same range of focus, your camera may simply give up and not autofocus until you manually move the lens into the correct region.

If I set f/22 on this Canon lens and focus more closely, it can be a stop or more underexposed, while with Nikon cameras and lenses, they compensate and give the same exposure.Don't let me scare you away from this lens since most of you always shoot in automatic — or with TTL flash, but if used with everything set manually and you need to change distances significantly, you will have to change your aperture setting to get the same effective exposure at each distance.You can ignore this with auto and manual TTL exposure, but it must be heeded when used with manual studio strobes or external exposure meters.Engraved into bottom rear of barrel near the mount, and filled with white paint.I've covered this above: the 180mm f/3.5 is Canon's sharpest lens, essentially diffraction limited even wide-open.If you can't get an ultrasharp image from this lens, you're Here's Canon's MTF curve, which shows engineers just how nearly perfect it is:Spherochromatism, sometimes called "color bokeh" by laymen, is a minor aberration which can add slight color fringes to out-of focus highlights.There is slight spherochromatism at 1:1, which goes away by f/5.6.With its straight 8-bladed diaphragm, this Canon 180mm f/3.5 makes 8-pointed More importantly, the 1.4x converter lets you get to 1.4x life size. Used on a tripod for indoor flower shots - stack focus. The working distance at 1x is very small. Another distinction the 180 L has is that it is currently the … magnification of 1:1 Serious macro is shot with flash or studio strobes, so Image Stabilization serves no purpose.However at half or one-third the price of the other lenses, it's an excellent choice on a budget. The Sigma 180mm is just too large and too heavy for an every day macro lens.

Canon suggests not using autofocus with extension tubes.In other words, the EF12 is a waste of time unless you really need to get just 10% closer than you can without the tube.It lets you focus from 0.48~1.501 meters, with magnifications of 1.21x ~ 0.15x.

Center crop at 100% magnification view below. The sharpness of this lens wide open is impressive. Most importantly its longer focal length allows us to stand back for better perspective and more room so we don't block our lighting.100mm is too short to get the best perspective rendering.

Click for the camera-original JPG:Canon makes a very high quality dual-element close-up lens, the It lets you get magnifications from 0.36x to 1.48x.It lets you do this with no loss of light as you get with Canon suggests not using autofocus with the close-up lens.It's sharp right out to the corners, even at f/3.5.There is no measurable distortion at all normal distances, and only the slightest invisible pincushion distortion at macro distances.For more critical use in the macro range, use these values in Ergonomics are great for normal use. Based on my own testing as well as Canon's MTF curves, it's sharper than every Canon ultrawide, sharper than every Canon normal and sharper than every Canon zoom lens of any range.It's sharper than every Canon lens less than 300mm.This lens is ultra sharp at every distance, even wide-open.The only Canon lenses as sharp or marginally better are some of Canon's five-digit price tag ultra-telephoto fixed lenses like the If you can't get a sharp photo with this lens, you're Better than optical perfection (almost all lenses are imperfect and more than good enough to Just move the focus ring at any time for instant manual-focus override.This is a full-frame lens, so it works on all formats. The Tamron SP AF 180mm f/3.5 Di LD (IF) Macro is a well-designed lens that's impresses on both APS-C and full-frame bodies Type: Macro lens Focal length: 180mm at infinity Aperture: 9 blades Its primary application is, obviously, macro photography but naturally it's not limited to that. a 252mm f/4.5 (180mm + 1.4x) or 360mm f/7 (180mm + EF 2x) combination.

This is no problem for shooting in any automatic mode as most people do at normal distances, but will result in different exposures as you change distance once you set a fixed exposure manually as pros often do in macro or studio settings.This is why I prefer to shoot the Nikon in my studio, since Nikon cameras and lenses compensate for this automatically — even in manual exposure. Due to the complexity introduced by the macro feature the lens is somewhat An internal focusing feature keeps the lens portable and the autofocus is quick, quiet, and precise. You’ll struggle to capture bug photos without scaring off your subject. More affordable than the above version with image stabilization.

The problem here is that chromatic aberration is not a problem at f/2.8 but they increase as you stop down.

The sharpness is not the greatest at f/2.8 and f/4, and stopping down doesn't help.
