As it is with Sony tradition, they have announced their new set of ergonomic standards with their most recent lens, which happens to be a 100mm STF G Master.

 

Unlike other GM series primes, you now have the AF/MF switch from the 70-200GM  on the lens barrel. Unlike that lens however, you also end up with a focus range limiting ring you get a focus range selector which adjusts he optics so you get close focusing capability but you can't focus on infinity anymore.

If you want a focus ring with distance scales on it, you can buy the 90mm Macro. If all you want is the focus button but not the other features, you can have a look at the also newly released 85/1.8, which has that button whereas the more expensive 55/1.8 and similarly priced 28/2 lack it.

An STF cream machine with OSS ... I am impressed. It could be a little faster though.

The AF/MF switch is also present on the 85GM.

 

But yes, ergonomics on the Sony E lens range is a big mess :(

 

Still, I'm quite happy to see that they listened to all the people asking for an affordable 85/1.8 and a STF lens with AF. And the "macro" (1:4) mode on the 100 STF should be quite useful too.

 

Now let's hope that 35/2 and 135/1.8 are coming next :)

I wonder how this 85mm unit compares with the Batis...

I'm happy this is a 100mm lens and not a 135mm (like the old STF) or 85mm (Like Fuji APD) as I find that the focal length more favorable compared to either but  yeah, I'd wish this were an f/2 lens without OSS. All the bodies have IBIS in them anyway, are they trying to say that IBIS is only good for lenses shorter than 85mm? How is that a good compromise for having a significantly heavier and larger body?

50GM does not have it though, again, why then? :). Also, I'd really like a sensible, resonably priced and sized 100/2 for best compromise instead of all the specialist lenses that we ended up with.

Same here. Had loved the handling and overall feel with Batis and almost bought it a few weeks ago where a store had both 25mm and 85mm in used but pristine condition. Walked out with the 25mm instead.

100mm f2.8 STF the opposite of the Nikkor 105mm f1.4? Both designed for smooth bokeh, they went a tad overboard with the aperture size, resulting in a strong swirl and quite heavy vignetting wide open for the focal length. 

With this Sony, puzzled why they did not go for a f2 design. The T5.6 shows it could have made good use of an extra stop...

The Nikkor without VR for a platform without IBIS, the Sony with OSS for a platform with IBIS.

 

The 85mm f1.8 is a nice addition to the platform. Although the basic specs are like the Zeiss Battis 85mm f1.8, the list price is less than half and the weight is kept a bit in check.

Wish I had the STF mode from Minolta 7 were implemented on newer cameras, preferably in single exposure mode.

 

For those who don't know, Minolta's one of the last film cameras (from year 2000) had a STF mode where it would do consecutive exposures on a single frame with different apertures to simulate the STF effect. It would calculate the necessary exposure time for each of the shots by itself and do everything automatically. The results were pretty comparable to a real STF lens and worked with every Minolta (and later Sony) AF lens. Downside is that even under bright light it takes a few seconds to complete the multiple exposure run so it was pretty useless on moving subjects.

 

This could've been implemented in today's digital cameras by moving the aperture during a single exposure or by doing a multiple exposure into a single RAW file. Shame it never happened.

The 100/2.8 STF is quite large for a 100/2.8. Same like the 135/2.8 STF was large for a 135/2.8.

Maybe the 100 STF will be as good wide open: zero vignetting and no cat eyes.

 

Supposedly, the 100 is T/5.6 instead of T/4.5 (like the 135 was) because of a thicker Apodization glass for smoother bokeh.

The example pictures in the review gives you really a feeling that you are there. I think it would be a good lens for documentations.

Could this be done on sensor level too? Too my understanding its the less orthogonal rays which are filtered. To my understanding digital sensors already do that a little but if there cold be a kind of gradient you could have the effect for every lens.

No, there is no way to do anything of the kind on sensor level.

Any point of the sensor receives the light from a multitude of directions through the optics, you can't choose what to get and not to get.

 

What you are proposing in your logic would just amount to heavy vignetting.
