Recently I had the opportunity to purchase a used Canon 50mm f/1.4 USM which is still in perfect condition. I also got a matching lens hood (ES-71 II).
The special feature of this lens is the wide open aperture of 1:1.4 which allows pictures with a quite short depth of field and at low light and the auto focus mechanism using an ultrasonic motor (USM) which allows continuous manual override even then auto focus is turned on.
Another special feature is the fact that this lens was already introduced in 1993 (also see the Canon Camera Museum) and is still being produced since then until today – which means it is now on the market for more than 20 years and can therefore considered to be a classic.
Take an older Canon EOS 40D, take some pictures with a small aperture and bright sky in the background… and then find out that the sensor is obviously forcible dusty. A testshot confirms that…
The Canon EOS 1100D (Rebel T3) is an affordable entry level DSLR which does not provide a dedicated button for the depth of field preview near the lens like the more expensive models, as the 550D. But in fact this function is available and can be configured to be activated with the “SET” button.
