☺️ Thank you for viewing from among many items. #Haruki's Camera Room ∞ See the Hidden Gems → ✏️ A great item that extends the focal length of a lens by 2x, a teleconverter ✅ KENKO C-AF 2X TELEPLUS MC7 ❤ Set Contents ・Teleconverter body, front and rear caps ❤ Condition ＜Appearance＞ Good ◎ ＜Optics＞ Good ◎ ＜Operation＞ Good ◎ ❤ Description By attaching it between the camera body and the lens, for example, a 300mm telephoto lens will have a focal length equivalent to about 600mm. However, by using a teleconverter, the effective aperture becomes smaller, so the f-stop value becomes two stops darker. If the original lens had an F-value of 4, the F-value will be 8 after attaching the teleconverter, and caution is required when shooting telephoto in dark places. ※ This is a camera accessory exclusively for EF lenses. (Not compatible with EF-S lenses) Also, generally, when used with lenses brighter than F2.8, autofocus (AF) will function, and manual focus is recommended for lenses darker than F2.8. By the way, I tried using it with a Canon EF 35-135mm 1:4-5.6 USM, and the AF function worked. There is a slight AF hesitation, but I was able to take pictures without any problems. This may be due to the fact that there was enough light during the daytime shooting and the performance of the USM lens.
