Canon EF 100mm F2.8 L IS USM Macro Review

 Returning in Sept, Concept took the incredibly uncommon phase of disclosing a new specific development definitely in comfort from any items. The topic was a novel 'Hybrid' visual picture assistance program designed to create up for two unique types of trembling online camera. Analysis more about it here, but generally the assistance is different from existing methods, which only identify and appropriate for changes in the position the relationships is directing, by also investing for straight and smooth in a trench changes in the position of the relationships due to handshake. This has little benefits at lengthy concentrate differs, but as the topic gets nearer it becomes gradually more essential, and in concept provides obtain the most for macro getting.

In Sept the organization successfully provided the first relationships to function this new specific progression, and to no excellent shock it became a 100mm macro. The EF 100mm F2.8 L IS USM Macro connects The rule eos eos amazing short-telephoto choice as a complement to (rather than a alternative for) the existing EF 100mm F2.8 USM Macro, and at a considerably excellent cost. Together with specific progression IS specific progression it income all the regular benefits associated with the top excellent 'L' banner, such as powerful, weathersealed create and the use of unique cup for the difference in aberrations. The visual development is of 15 components in 12 categories, along with just one ultra-low distribution cup element, and the 1:1 highest possible possible magnifier is obtained at a tiniest concentrate wide range of 0.3m.

Canon creates some quite particular statements for the durability of its new IS program, and it's value looking at these in details. The assistance is predicted to provide a 4 stop benefits at more time concentrate differs, losing to 3 prevents at 0.5x magnifier and 2 prevents at complete 1x magnifier. The first of these specifications is quite much par for the course for The rule eos eos existing IS relationships, but even with the Several program it's apparent that the stage of assistance at near differs is predicted to be relatively low (this despite The rule eos eos marketing content stating that it 'enables camcorders lovers to catch amazing close-up injections without the need for a tripod'). So the question audiences will definitely be asking is whether the combination of features provided by the new relationships is definitely impressive to rationalize buying it over the older, but well-regarded non-stabilized 100mm macro.
