In the blink of an eye, Zhang Aunt was nearly two years old. After several intermittent renewals, he finally signed for 296 days, and he was approaching 300 days!

Thanks to Zhang Da Ma, during the time of more than a year, nothing else was learned. The blood of the wallet was quite a few...
In early February of last year, the D7100's 18-140 machine was introduced into the Nikon. At that time, it took a total of 6,500 oceans. As a result... Nikon, who was born one day after I bought the camera, released the D7200.
As the saying goes, “Fixed focus has no dog's head†(I know someone would say: “Obviously it's 'fixed focus and no underdog'.†I’d like to say that it's a dog's head and I’m not obedient to you to come and bite me!), since the beginning of last February After Nikon's D7100's 18-140 machine, my heart has always been resentful of the maximum aperture of 3.5. After spending the summer vacation home, I consulted with my father and finally approved me to buy a fixed focus head.
Since the D7100 is an APS-C format body, relatively speaking, in the 7100 above, using a fixed focal length of 35mm focal length would be more appropriate (equivalent focal length 52.5mm), however, it may be expected to change the full width later (although I also I don't know when it was... ), plus the DX 35mm f/1.8G lens that you used to look at in the photos of Aunt Zhang, and you've always felt sorry for the moving purple edges.
Thinking again and again, eventually decided to start with 50.
Well, I admit it is fake out of the box.
Enter (pseudo) unpacking time below
In fact, these photos could have been filled with flash light...but my lights were in my school... I didn’t say it...it was tears... You’re going to look at them...
With D7100 fit!
Wait... It looks like something is wrong...
Okay...the hood is back...
To compare with the set of head 18-140MM ~~
Okay... it's really short (jing) small (han).
Because I had used classmates at school (AF 50mm f/1.8D), I took these two shots to briefly explain the differences between them.
Because there is only a 1.8G lens around, the figure will only be attached to the 1.8G lens.
First on the map!
Compared with the previous generation of the "human optics essence" AF NIKKOR 50mm f/1.8D, AF-S NIKKOR 50mm f/1.8G has a great change from the previous generation, the first change is the structure of the lens, from The previous generation of 5 groups of 6 tablets evolved into a new generation of 6 groups of 7 tablets, and it also contains an aspherical lens. On the Internet, this aspherical lens has a very important correction effect on the lens path (though I do not come out ......). The second is the lens more contacts. In addition, the most direct change in the structure is the change in lens quality. 1.8G is about 30 grams heavier than 1.8D, but because G head is larger than D head, it is compared with D head. Instead, it feels lighter.
As for the coating of lenses, the 1.8D coating is the oldest (after all, it is for film machines), but the coating of amber and purple is indeed very beautiful and extremely beautiful. The 1.8G is naturally equipped with a digitally optimized coating. The color of the coating is only green and purple. However, with regard to the new and old models, the optimization of the 1.8G coating for imaging should be even more powerful.
There is only one aperture lock lever on the 1.8D lens, and there is no aperture adjustment ring on the 1.8G. Instead, it is a focus mode switch lever.
Most of Nikon's lenses have a focus distance prompt design, 1.8D and 1.8G are certainly not exceptional, and the G-type lens has an independent focus prompt window, more professional.
As for the actual comparison chart between the two, and I will return to school when I start school, I will be able to talk about it again.
Write this, this article is almost over.
I don’t think there is anything to say about this lens. As I said at the beginning of this article, “Fixed focus is not a problemâ€. Therefore, if your camera is a full-frame camera, then I highly recommend this lens (after all, a few hundred 1.8D is also not worthy of your tens of thousands of fuselage Yeah), of course, we can afford to buy 58/1.4G ... ... when I did not say a few words in front of ... ...
As for the friends who are still using the width of the fuselage, like me, I think the performance of this lens is still very worthy of its price. Well, don't buy old electronics, buy 1.8G, don't buy 1.8D, and you'll have hundreds of pieces. (Don't look at me, I certainly don't smoke!)
As compared with the 35mm f/1.8G, the first is that its equivalent focal length is 75, so the photograph will be relatively larger, more suitable for portrait shooting, and 35mm lens shot out and the human eye See almost the size, sweeping the street, indoor are more suitable.
However, if you are a major portrait shooter , believe me, buy 50 , no mistake!
For the first time, Auntie Zhang made original and bad writing.
