With a disc with a diameter of 90 microns and 20cm, you have to be close to 1m to shoot it all (although it is not necessary to shoot it all, it is also very common). In this case, what macro is needed? It is enough to use the 70 end of 2470 ... Of course, it is also hard to carry it all day.

You can't shoot small things like bugs. 1: 1 The macro head with a long working distance is completely useless, but it is troublesome to shoot food. After all, the color and shape of food will change greatly after serving for 5- 10 minutes, not to mention the taste.
In the lens, it is best to use a flash to solve the performance problem. The fuselage is always an accessory of the lens, but the lens should have good light no matter how good it is, especially when playing macro. Therefore, getting an sb29s or a group of sbr200 is an inevitable choice for N families to play macros. And you don't consider the price factor, a lamp in front of 2470 is a fraction of the price.
Well, I looked at it again and found the remaining one. Do you use both? In that case, which one is convenient to choose ... If you buy it, you'd better make good use of the dx head. N dx heads will do. Think about it: 1755 is a mythical mtf curve of 2470, 85 microns and so on. ...
