Guys, how well does the Lee Seven5 kit work with this lens? Did anyone get the soft and hard ND filters? With the DR range of the a7RII, I am wondering if they are needed.
Works perfectly. Even the Seven5 CPL works without any vignetting.

Well I just dumped the hood. PITA
Put on a 52 to 58mm step up ring than added a empty 58mm filter ring.

Here is the cool part it does NOT stick out past the lens itself so it looks natural

Now maybe you could even sneak in a odd size like 60mm. So go 52 to 60mm and my bet is you could actually add 2 filter rings and have a really nice hood. I think I have a 60mm hood handy lets see if it sticks out

Here is 67mm. So 52 to 67 mm step up than 2 filter rings absolutely no vignetting at all. I think the answer maybe 62mm. One filter still has glass in it. Just a example of what a 67mm setup would look like but folks that want to use 2 filters no issues at all at 67mm. It kind of looks like a wide angle hood. Lets see if I can find a 62mm

So this one is tricky look above the adapter that is a 62mm thread. I think you could easily go 52mm to 62mm step up ring and add 2 empty rings and it does not stick out past the lens itself if it does its very slight. Don't go by the hood as its flared out some. Im going to order some 62mm stuff

Okay so I ordered a 52mm to 62mm step up and two filter rings. I ll get it tomorrow and we will compare again and see what looks best

I was looking at the hood on the 21mm . If you look closely on the lens itself there is a little silver ball and that is what is holding the hood on but the internal bracket in the hood is soft plastic so its bending every time . If it was metal bracket or hard plastic it would stick better . I tried loosening the screws inside the hood and try to make it it a smaller fit, It helped ever so slightly.

If it helps ... I've used a stacked Zeiss UV Filter and Zeiss CPL, both 52mm, without any obvious vignetting on my Loxia 21mm.

I would like a proof of concept image of that setup. That is just nearly impossible. I measured that with two ultra-slim 52mm filters may work if threads are removed from the topmost one.

Measured thickness not including threads is 4.5 mm. They are advertised as being "slim" ...
Edit: here is a link to the photo, taken at f4.0, focus around 1.5 meter, with Zeiss UV + POL filters.

Seems OK, but I will test some more next time the sun comes out ...

All right. If that is not cropped in any way then it really seems to work. This is puzzling. 58mm stepup ring and two ultra slim 58mm filters do hard vignette.

Many step up rings tend to shift forward in the process of going wider. They are bent metal and not machined metal, so the 90 degree turn from the male threads to the flat and then the second 90 degree turn for the female threads and not really 90 degrees and therefore the "flat portion isn't exactly parallel to the film plane. The shift forward is was causes the wider filter to hard vignette.
I have no idea how to tell which brands are OK (closer to 90) and which ones don't. The cheap ones from B&H tend to be bad for vignette. Going all the way to 67mm is more likely to work

Yeah, but I will go straight to 77mm or even 82mm (might look ridiculous) cuz those are my main filter packs.

Yea but you can do that only when you filter. Right now a 52-62 step up and 2 rings gives me a nice hood than just unscrew the whole package and use like 58-82 or whatever step up and use your filters. Or I can use 62mm and just take the rings off and leave the step up ring and use that. The hood just comes off too much and I never use them and just put them in the box for resale. I always adapt a new hood with metal screw ins. I damage them it's a really cheap fix. So you have a lot of options here. BTW this is why I made Choppy 1 and 2 on the VC 15. I have a ton of filter options now with it. I spent 20 dollars on the 62 hood setup today
Bill not sure but never really had a issue with step up rings. They seem to do the job

Bill had a point for sure but those kind of special stepup-rings are not that often available.
Onto other matters. Have a look at this sunstar.

No filters in use. That seems a weird reflection or ghost image. Never seen one with other lenses on A7R2. It is related to camera angle - leveled camera does not cause this. Only when pointing the camera upwards or downwards this appears.
