Yes, I did this to compare the MFD properties of the 50Z/1 nokton, 50Z/2 apo and the new 28Z/1.5 nokton. The 50Z/1 & 50Z/2 has precisely the same MFD (~36cm from lens filter) and the 28Z/1.5 frames to match them, but at a distance of 19cm from the nose of the lens. Also, all have about the same depth of field at MFD - about 1mm.
Results: let's just say noktons, are not ideal archival copy stand lenses wide open.
The VF/short MFD are 2 of the reasons I use to convince myself that I don't need a Leica.

Does anyone have a suggestion for a more compact hood/lens cap solution for this lens than the standard one that comes with it?
You might try a step-down ring combination of 49-46 and 46-40.5mm. (Sony makes a nice 40.5mm lens cap.) I haven't seen vignetting with that combination even when I've added a 49mm filter to the 50mm lens, as I did today. For convenience, I use those rings on both the 35 and 50mm APO lenses (although the 35 does add very slight vignetting in the corners with the 35 at infinity when a filter is used.)
Other thoughts:
A "micro" Op/Tech Hood Hat slips easily but snugly over the rings and lens if you want a bit of protection or wish to use it in lieu of the lens cap.
When I checked coverage from various oblique angles, the step-down rings seemed to provide protection from stray light comparable to that provided by the stock hood.
I recall that a 49-46 plus 46-39mm combination also worked without vignetting on the 50mm lens, but I never checked it with the addition of a filter.

The step up ring suggestion is good - thank you. After thinking about this more, I realized the 49 mm metal screw in lens hood and push cap from my Pentax 43/1.9 would work well on my 50/2 APO and be more compact so I’m going that route for now. Sorry, I should have thought of this before I posted.
Has anyone swapped the Voigtlander 50mm f/2 APO-Lanthar for the f/3.5 version? I did, and I’m starting to regret it. Both lenses are equally well corrected and outstanding, but I do miss that extra blur now and then....Plus, the 50mm f/2 APO pairs really nicely with the new 28mm f/2 APO.
Really? For me the 50mm 2.0 Apo was always too perfect and with no character or charme in the bokeh. Not so the new 28mm Apo. It is not this clinical or steril perfect. I love it. Only the bad MFD is a thing…

Hey, I have noticed you often describe lenses in broad terms, so I'm curious how you define certain things. You mentioned the 50/2 APO is clinical and sterile with no charm... What does that mean to you? I usually think of clinical as modern in performance, well-corrected, neutral, and with an undistracting rendering.. That's a signature I see in all 3 APO-Lanthar lenses, which makes sense given their similar optical design. Their design isn't aiming for character or imperfection in the rendering...if anything, it's intentionally the opposite.
You said the 28/2 APO isn't clinical or sterile, but to me it's just as well-corrected, if not more so, and its rendering feels even more refined than the 35 and the 50. The focus transition is especially smooth into the corners, and the specular highlights look more rounded, likely due to lower optical vignetting and very flat curvature.
Maybe the wider angle gives your compositions more energy, and that's what you're responding to comparing to a more normal 50mm view. I'm not trying to debate, just curious how you're seeing it, since I interpret it a bit differently based on tests and samples.

I was always too busy marveling at how much the subject jumps off the screen at f/2 with the 50 APO to think about the background. That to me is the best bokeh, when it takes a supporting role and serves only to amplify the subject.
But that aside, the rendering of the 35 and 50 Voigtlander APOs at f/2 with close subjects – the backgrounds remind me of the f/2 Zeiss Classic lenses (ZE/ZF) and the subject separation reminds me of the Otus lenses. A great combo, IMO.

I agree with your description.
I'm hoping Cosina updates the CV 50/2 APO with a cleaner look, dropping the chrome nose so it matches the CV 28/2 APO. For the CV 35/2 APO, I'd love to see a redesign that cuts the size down by about 30% while keeping the same image quality.
It would also be great if Cosina released special editions of these lenses in black paint and chrome.

Agreed. Just because they're APO lenses doesn't mean they have to be so serious and only come in regular black.
But the Voigtlander 50 and 35 APOs need a bit of a redesign, IMO. Leica has an extraordinary MFD and compact size with their 35 APO-M, and there's no reason that Cosina shouldn't try and improve both. I'm sure the next Leica 50 APO will have a close MFD as well, while retaining the smaller size.

Leica APO-SUMMICRON-M 35 F/2 ASPH's optical design is particularly difficult to manufacture.
From their optical diagram, the third group from the front is a cemented triplet triplet, which is really difficult to manufacture. Vast majority of modern lens only uses cemented doublet design.
I think I saw somewhere that every single piece of glass in Leica APO-SUMMICRON-M 35 F/2 ASPH are specialty glass. glass such as L-LAH85V is only sparingly used in ultra fancy Canon's 24-105 f2.8.
I think if cosine can make a 1/3 smaller 35/2 APO, the price may also be very unaffordable.

If that ends up being the case, I'd take 'unaffordable' in Cosina terms any day over 'unaffordable' in Leica terms.

They will want to make sure they don't undermine their own, newly released, APO-Lanthar 50mm f/3.5 lens. Which, in the end, it's (only) 8mm shorter, while being almost two stops slower.
