Canon 4D. Standard lens, 17-85mm. Adjust M file, and the maximum aperture can only be adjusted to 4 ... Excuse me, is the standard lens aperture only adjusted to 4?

the maximum aperture of 17-85 is not constant. Only the 17 wide-angle end can be opened to the maximum, and then the aperture will gradually decrease. Your m is only up to 4, so the lens should be selected in the middle focal length. Cosco zoom, the cheapest one is 55-25.

I think if the requirements are average and the price is low, choose 7-3 (of course, not Little Green, another one. There are only two models. )

if you want better picture quality and more vivid colors, Then we can consider Canon's four famous giants-

7-2 F4L RMB 67

7-2 F4L IS 85

7. -2f2.8l95

7-2f2.8lIS168 The higher the price, the better the performance. In the photography circle, if this is the focus of truth

, 5 F1.8 is good and the price is not high. But it's the same as your 17-85 focal length, and everything else is quite expensive.
