On November 11, 2023, Monster Adapter 魔环 announced its development plan for 「LA-FE2」.
As an extension of the previous 「LA-FE1」 product, support for Nikon (Nikkor) AF lenses without built-in motors.
Using the motor included in this adapter, torque can be output for these lenses to drive autofocus.

The LA-FE2 can be seen as a complete upgrade to the LA-FE1, supporting NIKKOR AF lenses without focus motors, or third-party F-mount lenses that fall into this category.
Externally, because the adapter ring has two built-in motors for focus and aperture, it is partially raised and may not fit because of physical interference with some products.
Already known such as Nikon's Pronea series of lens products developed for APS film, etc.,
Functionality covers the group of lenses supported by the LA-FE1 in addition to the F-mount AF type lenses without motors.
Looking forward to more results.
Due to the iterative nature of Sony's focusing algorithms, three generations and newer are recommended, which is roughly the bodies introduced in 2017 and after.
This type of body will have features such as eye focus on it, all of which can technically benefit the adapter lens.
Info can refer to G Drive支持 (Chinese) .
Stay tuned for related tests.
Most likely because these lenses were manufactured in an earlier period and were not designed for high resolution digital sensors.
Looking forward to more results.
The Z mount has two of the manufacturer's more unusual adapter rings:
However, it is known from inquiries that Monster Adapter has not reached an agreement with any of them at this time.
Nikon made an attempt at AF on a DSLR in 1983, with the model F3 AF, and accompanying lenses:
Time came in 1986, after Minolta introduced its Minolta AF system, Nikon introduced new AF lenses based on the physical foundation of the F-mount.
These lenses utilize a body-mounted focusing motor with a screw-drive mechanism at the interface of the mounting bayonet;
The wave of production of these lenses continued into the 2000-2010 generation, after which they coexisted with AF-S/AF-P lenses with built-in motors.
There is a discussion of Nikon lenses by Mr. Ken Rockwell, can be used as a reference.
Third-party manufacturers at this time, because they had to produce Canon EF-compatible lenses, the technology of the built-in focusing motor advanced, and gradually lenses without a focusing module became rare.

▲Difference with LA-FE1
[Question] How does the LA-FE2 compare to the previous LA-FE1?The LA-FE2 can be seen as a complete upgrade to the LA-FE1, supporting NIKKOR AF lenses without focus motors, or third-party F-mount lenses that fall into this category.
Externally, because the adapter ring has two built-in motors for focus and aperture, it is partially raised and may not fit because of physical interference with some products.
Already known such as Nikon's Pronea series of lens products developed for APS film, etc.,
were found by K.I.M tests.
なお、私の所有するFマウントAFレンズ/アダプターで、F3AF用AFテレコンバーターTC-16とIXニッコールレンズの物理的な取り付け不可を確認しています。

TC-16は互いの外装の一部が干渉するため、IXニッコールは既存のニコン製35mm一眼レフとほぼ同じ形でレンズ基部が衝突するためです。 pic.twitter.com/NX2uZTeIkw
Functionality covers the group of lenses supported by the LA-FE1 in addition to the F-mount AF type lenses without motors.
▲G-lens focusing speed
[Question] LA-FE2 when using a Nikon AF-S lens (or G-type lens) with a built-in focus motor.Is there a difference in focusing speed compared to the LA-FE1?
When driving a lens with a built-in focus motor, the FE2 uses the same microcode as this part of the FE1;
As long as the body and lens are identical, their focusing performance should be the same.
Looking forward to more results.
▲Recommended Camera
[Question] Is there recommended cameras for the LA-FE2?Due to the iterative nature of Sony's focusing algorithms, three generations and newer are recommended, which is roughly the bodies introduced in 2017 and after.
This type of body will have features such as eye focus on it, all of which can technically benefit the adapter lens.
Info can refer to G Drive支持 (Chinese) .
▲Heavy-duty focusing lenses push
[Question] Is it possible to push a type of lens such as the 80-200mm F2.8, which seems to have a heavier focus lens?[Asked designer]
Although the LA-FE2 motor looks small in size, it should have no problem pushing the AF 80-200/2.8.
Stay tuned for related tests.
◇100%画面不够清晰
[Question] The shot was taken and found to be not sharp enough and not in solid focus.Most likely because these lenses were manufactured in an earlier period and were not designed for high resolution digital sensors.
This occurs on the 61MP A7R5 model (lens is AF 85mm F1.4 D),
found by Asobinet in testing.
撮影後にフォーカス位置のチェック（等倍）すると「あれ？AF外したかな？」と思ったものの、帰宅してパソコンで確認すると問題なし。6100万画素の等倍には耐えきれないだけだったのかなと。

フィルム用レンズも約30年後に6100万画素CMOSで等倍チェックされるとは思っていなかっただろうなぁ。 pic.twitter.com/CR2NBJ9BWO
This is most likely not an isolated case, i.e. the lens design resolution is lower than today's top sensor resolution;
You can consider downsizing in post-production, or choosing models such as 24MP or 33MP.
Looking forward to more results.
◇Adapter by adapter, to the Z-mount
[Question] Is it possible to set up the LA-FE2 as a Z-mount application with the associated adapter ring for E-Z?The Z mount has two of the manufacturer's more unusual adapter rings:
- 天工 Techart「TZE-01」「TZE-02」
- 迦百列 Megadap「ETZ11」「ETZ21」「ETZ21 Pro」
both of which use E-mount lenses adapted to the Z-mount.
So as soon as the LA-FE2 appeared, there were cries of speculation.
However, it is known from inquiries that Monster Adapter has not reached an agreement with any of them at this time.
But judging from personal experience there is an 80% chance that it won't work and a 10% chance that it will result in a burnout;
Looking forward to the results tests though.
If you are going to test, please be sure to be safe. neither Monster Adapter nor this unofficial blog can be held responsible for this.

Incidentally, currently trying to use an AF D-mount lens with autofocus on a Nikon Z mount body,
the practiced solution is to use the TZM, with the F-M adapter, to achieve focus by moving the lens as a whole.
About Nikon AF Lenses
Nikon made an attempt at AF on a DSLR in 1983, with the model F3 AF, and accompanying lenses:
- Nikkor AI AF 80mm F2.8 S
- Nikkor AI AF ED 200mm F3.5 S
Time came in 1986, after Minolta introduced its Minolta AF system, Nikon introduced new AF lenses based on the physical foundation of the F-mount.
These lenses utilize a body-mounted focusing motor with a screw-drive mechanism at the interface of the mounting bayonet;
The auto iris mechanism is selected on the lens by mechanical action transmitted through the body bayonet, as is the case with the auto iris mechanism.
The wave of production of these lenses continued into the 2000-2010 generation, after which they coexisted with AF-S/AF-P lenses with built-in motors.
There is a discussion of Nikon lenses by Mr. Ken Rockwell, can be used as a reference.
Third-party manufacturers at this time, because they had to produce Canon EF-compatible lenses, the technology of the built-in focusing motor advanced, and gradually lenses without a focusing module became rare.
