Is there a big difference between Nikon's lens 5mm1.4D and 5mm1.8D imaging

the difference between p>1.8D and 1.4D imaging is relatively small.

the advantage of p>1.4D is that Jiao Wai feels better than 1.8 except that it has a larger aperture. Jiao Wai of 1.8 is somewhat hard. 1.4 is better.

the workmanship is also 1.4, which is better. Big eyes, too After all, where is the price?

but in the case of infinite focal distance, it is what we generally call a distant view, a small aperture. The resolution of 1.8 is better than 1.4.

actually, I think 1.8 is basically enough for the header. Even the blurring of 1.4 will not be very good. After all, it's only 5 mm. Moreover, when people usually use it, they also close one or two apertures, which makes the picture sharper.

generally speaking, there are two kinds, one is to buy 1.8D or the new af-s 5mm1.4G If it is a DX fuselage, you can also consider the DX 35mm f1.8G, which will be on the market soon, and the price will not be too expensive. The DX has a header vision. MTF is also excellent now, better than the old 5mm1.8D d.
