Another telephoto macro lens with a maximum magnification of 1x. Life-size close-ups can be taken from a farther distance without disturbing the subject (insects, etc.). The internal floating system minimizes fluctuations in aberrations caused by changes in the focusing distance. Optical performance is outstanding from 1x to infinity.

The Canon EF 180mm f/3.5L Macro USM Autofocus Lens shoots high quality photos throughout the focusing distance range from 1x to infinity. Three UD-glass elements are present in order to correct any residual chromatic aberrations. Operability is further enhanced through a wide manual focus ring. Another advantage of this lens is its internal focusing feature which does not cause the lens length to change or the front element to rotate. This lens incorporates distance information with E-TTL II (body independent) flash units.

• Internal Focusing, Floating Element

• Compatible with EF Extender 1.4x and 2x (manual focus only with Extender 2x).

Canon EF 180mm f/3.5 L USM Macro Lens Review by the-digital-picture.com

The Canon EF 180mm f/3.5 L USM Macro Lens is Canon’s longest macro lens. This lens offers the longest 1:1 macro working distance of any Canon lens and produces a beautifully smooth out of focus background. Another distinction the Canon EF 180mm f/3.5 L USM Macro Lens has is that it is currently the Canon’s longest and heaviest black lens. This is an L lens, so addictingly excellent build quality comes along with this weight.

Though it has Ring USM (Ultrasonic Motor) and focuses quietly, the Canon EF 180mm f/3.5 L USM Macro Lens’ AF is anything but high speed.

Canon’s macro lenses are all very sharp – and the Canon EF 180mm f/3.5 L USM Macro Lens is no exception.

Canon EF 180mm f/3.5 L USM macro – Review by photozone.de

The Canon EF 180mm f/3.5 USM L macro is an interesting lens with a very good optical performance and exceptional mechanical qualities. Nonetheless the lens wasn’t really able to fulfill the high expectations associated with a Canon L grade lens – there’re even some zoom lenses performing better in terms of resolution. Beyond the resolution aspect the lens showed pretty perfect performance figures – minimal vignetting, next to non-existent distortions and marginal chromatic aberration. The bokeh, the quality of the out-of-focus blur is relatively decent although not stellar. The AF performance of the lens is a bit of a mixed bag. If the in-focus point is in a relatively close proximity to the current setting the AF is fast. However, if the camera has no guidance where to go the AF is extremely slow. That said AF speed isn’t really relevant for pure macro photography where you tend to use manual focusing anyway. Macro photographers will certainly appreciate the “true” IF design (constant physical length) as well as the increased working distance compared to the EF 100mm f/2.8 USM macro. If macro capabilities aren’t on your wish list you may prefer to look elsewhere though.
