Sony's full-frame E-mount now has only two macro lenses, one is the FE 90mm F2.8 Macro G OSS (SEL90M28G) positioned in the high-end G series, and the other is the entry-level FE 50mm F2.8 Macro (SEL50M28). ), Sony lenses that want a native E-mount can only be selected in these two models.
The official difference between the two shots is about 3,000 yuan (if there is a discount for a Sony gold member or a silver member, I'm a silver member, so the price of 90 2.8 is 6400, 50 2.8 is 3919). Considering that I already have a FE55 1.8ZA, in order not to repeat the focal segment, I chose FE90 2.8 in the end, but I have to eat again.

Sony/Sony SEL50M28 FE 50mm F2.8 Full Frame Standard Macro Lens 3999 yuan Tmall Select Direct Links Why is it the cheapest G lens? Look at this picture.
However, although it is the cheapest G lens, FE90 2.8 has a very good score in the DXO test. In all Sony's FE lens mounts, it ranked third in overall performance and ranked first in sharpness. (FE55 overall ranking is actually higher than FE90, incredible)
(Talk about it in advance: I don't have the power to take the camera after I finish the box. I get charged elsewhere, so only the first few are shot on the background.)
The package main color of FE90 2.8 is still Sony's usual orange color with some lens parameters.
The sign of the G lens virtually increased the forcing, but the background is black, and the orange without the GM looks so obvious.
The size of the entire lens is very large, with only two-thirds of the FE55 1.8ZA. The hood is not a lotus but an entire cylinder.
Comes with a leather storage bag, which is also much larger than the FE55.
The lens side is the focus lock button, focusing distance lever, anti-shake switch. When shooting macros, it is best to set the focus distance at 0.5-0.28m, so that the focus speed will be slightly faster.
Switching manual/autofocus is done by pushing and pulling the focus ring, but I personally prefer to have a separate lever.
The focus ring is made of metal. The lower three rows of numbers represent the magnification (maximum 1:1), focusing distance (feet), and focusing distance (meters). The focusing position can be adjusted according to the magnification only when manual focusing is in progress. The FE90 2.8 is internal focus and uses an ultrasonic motor.
FE90 2.8 was installed on my A7M2. The micro-single became a cannon with more than 600 grams of lens and only 400 grams of A7M2, so it was top-heavy.
Take a few shots to see the effect.

FE90 2.8 is the most criticized place is its focus, and compared to the aperture greater FE55 1.8, the focus is indeed weaker, only sharp knife, no milk.

However, due to the long focal length, the moon can finally see a little crater (this one was cut off).

The strange thing is that after a period of time, FE90 2.8 interface will have a feeling of heat, and the battery power consumption is much higher than the FE55 1.8, probably because of the long focusing stroke.
to sum upThe selection of 90 2.8 and 50 2.8 is very simple. When the funds are sufficient, it will be selected as 90 2.8. If the funds are insufficient, but the quality of the 50 2.8 is too low, then the old frog's 60 micro will be selected, and the 2:1 magnification may be taken. It was used as a microscope, but although it has an E-mount, it is not designed for a full-frame body, and it is a full manual lens.
advantage:
High sharpness
.
All-metal material, support splash-proof.
Can be used as a macro lens, 90mm focal length can also guest portrait lens.
Disadvantages:
Too big and too heavy, with A7 series micro single heads.
Extra-focus quality.
