comment:I spent about a year with the A-mount 135mm STF. It seemed like a lens I would love as I like taking pictures of flowers, but I didn't like the amount of color fringing wide-open or the extending manual focus. This mirrorless lens doesn't seem that closely related to the older STF prime. To start it has AF and internal focus, and it is designed for digital mirrorless bodies instead of film SLRs.

This is the first GM branded lens I've used. I am not sure why I've avoided them other than that they are not inexpensive. This was the most I've ever spent so far on a single used lens--more than I paid for the new 20mm F1.8 G. It does seem to be about the cheapest used GM prime. Brand new it is currently $200 more than the 24 mm and 35 mm GM primes on sale. "Made in Thailand"

It is a rather large lens. It is considerably bigger than the 100 mm F2 primes on their AF adapters. It is slightly lighter than the manual A-mount STF, but it handles much nicer on the camera.

The choice of two partially overlapping AF ranges is unique. It is oddly implemented as a rotating ring with a lock button that doesn't really lock. I suppose this at least avoids adding another cheap looking two position switch to the left side of the barrel. Unfortunately there are AF/MF and Steady Shot override switches there.

The aperture control on the lens is nicer than the ones on the G primes, but the action is still not quite as solid as the ones on the little Sigma primes. The A position is fairly solid. The aperture control direction is opposite of that of the A-mount STF lens. The third step detents between 8 and 5.6 are three times further apart than the others. A small printed STF and some lines seem to indicate that this is the only STF zone, but the STF effect is still visibly effective outside that range.

I appreciate that the transmission values are used exclusively in place of f numbers. There is a T printed on the aperture scale, but in camera and the exif data treats these as F numbers. The 100 mm F2 primes are darker in the center when stopped down to F5.6, but they have less corner shading.

The aperture itself is not very symmetrical when fully stopped down to f/22, but it is fairly smooth otherwise. This may not be a lens for fans of diffraction spikes.

While it is not as well corrected in the focal plane as the old F2 primes at similar brightness, it is more corrected than the A-mount STF. The F2s are definitely sharper for document reproduction, but it is unlikely anyone is buying this lens for that task.

Autofocus works well despite using a simpler piezo linear motor (DDSSM in Sony acronym,) Piezo motors are inherently fragile, but the alternative linear motors probably are too. It has less breathing than the A-mount STF, but it still reduces its angle of view with closer focus.

ownership:I own this lens
compared to:Minolta 135 STF
(+ various other lenses)
price paid:1 444,15 € (used)
positive:+ very smooth bokeh
+ has autofocus (unlike other STF lenses)
+ quite useful focal length
negative:- focus range limiter has no option for whole range
- would be nice to have better magnification
- aperture wise bit on the slow side
- not the cheapest lens
comment:If the 135STF was already nice lens, providing similar STF effect to little shorter focal length with modern AF makes this lens even more useful. T5.6 is bit disappointing, but not the end of the world.

compared to:Sony - FE 90 F2.8 Macro G OSS
Sony Carl Zeiss - 135 F1.8 ZA Sonnar T* (My previous sharpest lens.)
Minolta - AF 100 F2.8 Macro D
price paid:$2018 New
positive:Bokeh amazingly smooth up to about f8 and good beyond.
AF on a STF!!!
Extremely sharp at f2.8 all over except the extreme corners where it’s only very sharp.
AF is accurate, fast and very silent.
One can choose whether to adjust the aperture on the lens or on the camera or auto .
Focus hold button can be set as eye-focus in camera.
OSS really woks great.
Weight only 700g for this big lens is impressive. Internal focusing keeps the balance of the set.
Close focus option.
Works great with the Kenko extension tubes for FE.
negative:Non really, well, a T-stop at 5.6 is a tad low but I believe it would become a monster-big lens if brighter as it is quite big already compared to the Sony/Minolta 100mm f.2.8 Macro.
Expensive, but hey it's a GM lens.
comment:Love this new lens that is going to be my no 1 lens for E-mount.
Will compare it with my previous favourite, the Sony - FE 90 F2.8 Macro G OSS when time and wheater permits it.
More on weight: Only 200g more than the A 100/2.8 Macro and 100g more than the FE 90/2.8 macro and 300g less than the ZA 135/1.8. Time will tell how it will withstand wear and tear in the long run as it’s not an all metal lens but feels very solid.
It’s expensive but the GM really shows what it stands for.

I believe for sure that Sony made a winner here!

Discoverd yesterday that in some circumstances one can indeed get some hard to fix fringe. Water agains the sun and the reflections gets purple/magenta and even some green on tings sticking into the water. Also at min close shots some subjects will give some too but not severe..

Edit: Discoverd 3 days ago that certain small patterns creates moire that is hard to fix, same pattern with other lenses doesn't give this effect :-(

compared to:Sony 135STF, Minolta 100/2, Tamron 90/2.8
price paid:
missing
positive:Bokeh, the rendering of out of focus areas is just stunning
Sharp wide open
Good AF
negative:Slow, it´s a T5.6 and needs lots of light or bump the iso up. Not a big problem with the a7rii, but still an issue in darker situations.
comment:For me this is a dream come true! I love the old 135STF, but it´s slow working since it´s manual focus. I like 100mm focal length better then 135mm. Eyefocus works great and the "focus hold" button on the lens can be assigned for this, neat!
On an e-mount camera the old 135STF with adapter is a few mm longer and it extends when focusing. The 100STF is internal focus and lens body is little wider then the 135STF, still 72mm filters. So a big lens compared to the 100/2.
Build quality and feel is great, even MF feel good. Aperture ring is de-clickeble with a small switch.
Balance feel good on the a7rii.
It´s still a matter of taste, some people don´t like the STF look/rendering others love it. I´m one of those who love it!
I dare to say that Sony might reach a bigger group of buyers with this lens than the old 135STF did due to being native E-mount and autofocus.
