Such old optical constructions as the tested Canon 135L often have problems with work against bright light. To tell you the truth I didn’t expect fantastic results here and I wasn’t surprised they are indeed far from fantastic. Light artifacts appear during the work on both types of sensor and no matter what aperture value is used. Fortunately they are visible only when the source of bright light is situated very close to the frame corner or directly inside the frame; such situations rarely happen when you work with a 135 mm lens. Apart from that you can always use a hood which is a part of the accessory kit.
