I said it before: aperture rings on lenses are useless. I do not understand why it is dedicated to aperture. If it was a control ring I could set to any parameter, I would understand, but a dedicated aperture ring? Why? I do not need it. I do not want it. There is a reason Minolta and Canon moved towards the modern interface with everything under your index finger and thumb.

I think it is major design error that you cannot turn it off. That to me would be a reason not to buy that lens.

Well, I am not all that surprised that users on the Dyxum forum seems concerned only about stills and fails to see the need for video aperture control.

Cinema lenses do have (click less) aperture rings for a reason. Remember that E-mount is also a video camera mount. GM lenses should be fully featured for both stills and video.

I wouldn't make my lens choice based on the right but I find it easier to use than dials.

Mainly because dyxum is a still photography based forum. They've been pretty clear about that and hence you don't see many of the concerns from a video perspective discussed, aired or appreciated here.

I shoot video mostly in auto mode so the aperture ring makes no difference for me but I can see why videographers would appreciate this. Especially the clickless option. Even more reason to add it to constant aperture zooms. Though GM zooms are not parfocals, so I guess serious videographers wouldn't use this zoom.

No GAS here. I still regret buying my ZA 135/1.8.

I know that videographers use aperture rings. But do you know why?

They prefer manual focus with the possibility to use focusing rigs to have predictable focus throws. Focus by wire is a no go for videographers.

Furthermore, a videographers wants T-stop control, not f-stop control, to have reliable lighting.

This aperture ring does not make sense for videographers either.

This clearly is a stills lens first. If you want cine lenses, take a look at the Canon EOS Cine lenses. The Sony 135mm f/1.8 is not a cine lens.

I understand that some people like to have some control on the lens, but why that has to be aperture and not, say, ISO, I do not understand. Same goes for the dedicated ev dial on modern cameras.

And yes, Dyxum is stills oriented. We could use a video sub forum imho.

Circling back to comment on this lens after reviewing specs of the lens and looking at sample images. Between this and the 24 1.4 fe sony has really taken their lens manufacturing to the next level. Maybe top of the game tbh

I couldn't disagree more ;-)
- I guess the T-stop is consistently close to the F-stop on this lens.
- The ring is de-clickable.

You "guess" it is close to T-stops? And yes, the focus by wire is linear, but how do you use focus rigs? So, your only argument is it is de-clickable?

And even if you would be right, it is still annoying for me and others that you cannot turn the thing off. I do not understand why it has to be a dedicated ring

while it would nice to have t-stops, it wouldn't serve the purpose of a dual video+stills lens. The declicking aperture is aimed at videographers and as with anything serving multiple purposes i.e. in this case still+video its a compromise and a good one at that for those who are not interested in spending ££££ on video centric lenses.

Because it can't have clicks and even if it did wouldn't be marked like aperture. I can't set the lens to any aperture without looking at the screen/EVF. You could argue why that's important perhaps its not important but I like it none the less lol. I liked the aperture ring on old lenses and its nice to have them back.

Now I look at a scene or a shot I want to take and I already know what aperture I need before moving the camera to my eye. Quickly turn the ring and shoot. I like the way that works
Plus I am more likely (and have done in the past) to accidentally change the aperture by turning the dial than the aperture ring. So if anything I have the same problem you guys have with aperture ring but with dials instead

Agree with you on the EV dial though mostly because I don't use it much.

Agreed.

Everyone satisfied by rings and dials that can be repurposed for anything. The Canon style lens ring, with Batis style LCD readout, with Samsung NX-1 style lens ring engagement button, with Sony de-click option would address all concerns.

But all of that still wouldn't equal a99II silent multi control (with top side LCD)... Because the a99II makes it work with any lens.

That's handy for cameras without top side LCD's.

Used to be a lot of complaints about that around here. Had the problem myself on a900. Can't say why a99II doesn't plague me with the same. I really can't say why.
