How to choose Canon SLR lens?

The image quality of 18-200 lens is really weak, which is much worse than that of 24- 105 lens. If you are keen on image quality, you can see the difference at a glance.

However, it cannot be said that 18-200 cannot be used. This head-on consumer group is ordinary people, and the purpose of shooting is ordinary photography, not professional photography lens. Therefore, if you are not so strict about the picture quality and the purpose of taking pictures is not to attend the awards, then this lens can still be used.

24- 105 is not suitable for 50D, even if it requires high quality. Because 50D is a non-full-frame camera, the lens will be installed with a coefficient of 1.6 times, and then 24- 105 times 1.6 becomes 38-168 mm. The telephoto end looks cheap, but the wide-angle end is seriously lost, and there is almost no wide angle.

Therefore, this lens is not suitable for use on non-Quan Huafu machines. It was originally used as the head of a full-frame machine such as 5D2. Some people say that they can make up for it by taking pictures. This method is feasible, but the specific operation is more troublesome. It's ok to take a few photos after the trip, but if you need to take a bunch of wide-area scenery photos, you will faint.

Canon (Canon? ), a leading comprehensive group in Japan that produces video and information products, has been globalized and extended to various fields after years of unremitting efforts since the establishment of 1937.
