我想問吓如果支Canon 135L加左1.4X teleconvertor
1) 最近對焦距離仍是0.9m or 0.9x1.4=1.26?
2) 最大放大培數仍是0.19 or 0.19x1.4=2.66?
Thx a lot

after adding a 1.4x, 135L's minium focusing distance remains at 0.9m, but the max magnification will increase from 0.19x to 0.27x.

Thanks for your information ar
By the way, how about the image qualiyt after adding 1.4X teleconvetor.
Will the image quality drop a lot??
Will the auto focus speed drop a lot??
Thanks a lot again!!

AF speed drops by 6x%
no significant degradation of image quality

我仲想問吓Kenko支1.4X teleconvertor 同canon 原廠1.4X o既 image quality分別大嗎??
