p.1 #1 · Alternative Voigtländer Hoods for Filter Setup
Folks, recently I've been enjoying shooting my raft of excellent Voigtländer (Sony) lenses. With that said, I've encountered a bit of a friction point: dealing with filters. As a Sony A7CR user, I want to shoot my Noktons during the day occasionally with a wider aperture, but I don't love what the EFCS shutter type does to the bokeh, thus I would like to keep the shutter speed lower. I have a suitable neutral density filter for accomplishing this in most cases, but the threaded hoods on most of my lenses create a cumbersome process to utilize the filter.
With that said, I do respect and appreciate how the stock hoods on the lenses protect the front element from damage and shield it from the sun. I had a thought to invest in magnetic filters and use a protective filter as a "base," in the hopes that some shading would be provided by the filter(s). However, proceeding down this route for all my lenses would be costly, so I wouldn't want to rush into it and discover that it's not an ideal solution in its own right.
I was wondering if any other FMers have some clever ideas to address this kind of situation. Is there an option I'm not considering? 3d printed hoods with a filter thread? Rubber hoods + threaded filters? I'm also thinking in parallel about how to bridge between the different filter thread sizes on my lenses: 58 and 62 being most common, though not forgetting the 49mm of the 28mm ƒ/1.5.
Perhaps there's a practical solution that addresses all of these challenges.
STC marks A7CR fit specifically, but the Kase's probably fit too (ask them first though in case).
Interesting suggestion, I really appreciate your bringing it to my attention! I have vague memories of a similar system from Kolari a while ago, but there might have been some compatibility issue with the "C" models. It's my understanding that rear filters such as that could potentially affect infinity focus, do you know if that's the case on this one?

The sensor idea seems like more delicate work than just threading on an ND when needed. It talks about scratches possibly happening internally on the product page but interesting that it exists.
The magnetic adaptor ring from Urth is $19 - I haven't tried it but will probably go this route, or similar.
Would try to find info on the quality of the ND/CPL and then the cost of the adaptor rings to cover them. Nice that it will likely all slot into the voigtlander lens hoods. Should be okay on the lens filter in terms of weight but it might add up.
Protective filter (I use those for peace of mind too) and hood seem to be fine, don't think the adaptor will add much to that.
I probably won't leave on the magnetic nd the whole time. I'm also not sure how strong it is, you'd think it'd be okay but that is a thin width on those adaptors ... the hood should cover you for accidentally knocking it though.
Might still be a hassle picking it off, but should be easier than threading it on.
I'm picturing the noktons when I'm typing this, with the focus on protecting bokeh, the 50mm APO has a much longer hood right.
The nokton hoods are already really short so unless there's a screw on hood that flares out significantly, the magnets might be your best bet.

Yes, the more I research into the clip-in filter option the more it seems like it comes with trade-offs of its own that make it awkward.
I have had magnetic lens filters and caps in the past and had the unfortunate experience of sliding them on or off incorrectly in some way and scratching a lens — let's just say it wasn't a good time, hence why I'm reticent to blithely go that route. I would like some protection for the front element, and unfortunately (or fortunately) the threaded hoods that come with (most) of the lenses do an excellent job at both protection and hooding, albeit not with filters.
To be honest, I don't even know why the hoods come with threads at all, I couldn't seem to get my fingers in there to screw in a filter, and I dislike the whole interchange of removing the hood, finding a pocket to put it in, and then screwing on a filter and maybe re-attaching the hood.
If there were such a thing as a magnetic hood, it would be easy to simply attach it to a magnetic ring if needed. Maybe something shaped like a sun visor on a hat that you could use to direct the shielding to one side or another.
Returning to the point; it seems like some sort of magnetic system would technically work, however I would probably also need magnetic UV filters of some kind to ensure I'm not accidentally scratching the lens with the metal cap(s), thus raising the cost tremendously.

You can definitely screw in a protective filter into the hood, it's a little fiddly but you only need to do it once. Place the filter in roughly the right spot, just gently rotate it in place using two fingers spaced out, resting on the outer thread.
The protective filters do add some not insignificant cost and yes it only really makes sense this way if you get one for each. I already bite the bullet and get them for new CV glass (hoya HD mk ii protective) mostly for peace of mind and not having to faff about with this.
So I would plan to screw in the magnetic attachment adaptor to the protective filter, screw the filter into the hood and the hood into the lens.
--- If the lenses are the same filter size, you might only need one though, and can just unscrew the hood from one and screw onto the other when you swap lenses, with everything attached to the hood. Quite a bit of extra hassle added onto the faff with changing lens out and about already...avoiding it with the cost of a protective filter+magnetic attachment adaptor per lens if these are your go-tos.
Drop a magnetic ND filter when needed (would be the plan) but I've not tried it yet, though seems like a good solution.
Hopefully someone else has and can confirm for us both with regards to dropping it on there with the hood still on as well as taking it off. Looking down at them now though, I don't think it would be that difficult. It shouldn't brush up against the hood either, they do flare out a little. Should be pinchable.
When the weather isn't miserable here I'll take a look and see if I can find any reviews on the quality of the NDs with companies offerring magnetic ones.

I would also point out that once you have the protective filter in and then have to go and add an ND filter or CPL, or heaven forbid, both, it's going to very quickly start getting into physical vignette territory unless you go through the fiddly process to take it out.
Unfortunately the lenses are not all the same filter thread size, being 58mm, 62mm, and 49mm.

Why don't you just use the fully electronic shutter then?

The sensor has a pretty strong Jell-O effect with moving subjects when reading out at full bit depth in stills, so I'd prefer not to opt for that unless absolutely necessary.

I use rubber hoods most of the time with my Voigtlander lenses. They all have threads and I have enough that I only need two filter sizes with any set of lenses I take. A rubber hood costs less than five dollars, is light, and makes filter use a breeze.

Any robust recs, or are generics sufficient?

I get the cheap Sensei ones at B & H and they are a surprisingly good quality.
