Hmm… hard to belive that Cosina’s original bayonet hoods doesn’t fit with regular filters, that are not wider than lens cap. Can someone share experience with 43mm filters and LH 6 shades?

Are you thinking of a different lens perhaps? When I had the 28 Ultron II, both hoods worked with filters. The only filters that don't often work with CV-M hoods are Breakthrough Photography filters because the knurling is too thick, which is a design flaw on Breakthrough's part, IMO.

I have the LH-6 hood with a B+W UV filter on my Voigtlander 35mm f/1.4 Nokton. It also works with the new CV 28/1.5 Nokton with a filter attached.

Nope I tried it before I posted. I think it depends on the filter. I don't use protective filters--they might work, but my Urth variable-ND filter and my B + W polarizing filter do not. My main comment, however was that I had doubt that the filter extender that was referenced in the earlier post would work with the hood. I still think that is a concern and I would want to check that out before I considered it a solution to the silver ring issue.

If the filter is not wider than the lens cap it will work, but the hood just barely fits over the lens cap if the filter is even 1mm or perhaps 2mm wider in diameter than the lens cap it will not work with the hood.

There's some lateral and axial chromatic aberration, but it's well controlled, especially when compared to the Leica 28/1.4 Lux.
So far, no negatives to mention. I believe Cosina won't make any optical alterations; it's a definite winner so far.Hi Fred, will you be able to test the lens on a FF Sony body? I don't expect it will be great in the corners WO given how wide it is and optimized for Leica, but if it cleans up by 2.8 or even F4 it might be worth considering.
Thanks
MikeHi Mike, I don't have my Sony body anymore but I will try to borrow one for a quick test.Thanks Fred
Update: I recently purchased a Sony A7R II from the buy and sell board. I'll be conducting tests on the Sony sensor for the upcoming review.

It seems to be the Vintage Line default. 75/1.5 is the only one in current Vintage Line without this type of shiny front ring but the recent releases in other lines have avoided it.
I'll use mine with the hood (I always do) so the shiny ring doesn't interfere.
The entire "vintage line" features a chrome front ring used with a bayonet hood design. Juha mentioned the exception, the CV 75/1.5, which also has a different hood design.
The shinier material may cause reflections, but using the hood significantly reduces that, although not entirely. Cosina is maintaining consistency here, even though many of us would prefer a black front ring.

Hi Steve,
The issue might be caused by the fact that all variable ND filters are wider than usual to accommodate the rotating hardware. It works fine with normal UV and ND filters, as I use them regularly.

Yes, and circular polarizing filters that vary in strength with rotation of the filter also have a little bigger rings and they don't work with the hood either.

Hi Fred - How is the focus ring and overall tactile/haptic experience with the lens? I remember I found the 50mm f1.5 very stiff. How is this 28mm f1.5 as far as ease of focus? How is the focus throw?

The increase in resolution can make diffraction more apparent, but it's important to note that diffraction itself doesn't change. At the pixel level (100% magnification), I notice some softening at f/8 when using the M10-R.
Hi Fred,
This is a bit of a walk…
If memory serves, there are some Leica M lenses whose peak resolution sets in early (f2.8) It was reported (likely by Erwin Puts) diffraction became evident at f/5.6, maybe f6.7. I’m wondering if some of Cosinas newer offerings are following this path. Rarely is f/6.7 reviewed in tests. But I was looking at some resolution tests of the 35/2 Ultron and the difference between f/5.6 and f/8 was pronounced. It made me wonder.

I believe viewable onset of diffraction is very dependent on the resolution of the sensor in your camera.
You should get an idea of how well recent Voigtlander lenses 'sharpen up' if you check Fred's lens reviews. He provides 100% crops through the aperture range (but maybe only in full stops?). From my recollection, a lot of the recent lenses are already very sharp near wide open and you're usually only gaining depth of field and perhaps more even across-frame performance by stopping down.

Yes and no.
The resolution of your sensor will determine the amount of diffraction *per pixel*, so if you are peeping at 1:1 it will be more obvious just because the higher resolution sensor is more magnified viewed at 1:1 (the pixels are smaller)
But at the image level diffraction is determined by the lens. Viewed onscreen or printed with the image dimensions the same, a high Rez and lower rez sensor will display the same dulling due to diffraction at small apertures.

A simple diffraction experiment from awhile back, hopefully self explanatory...
Diffraction 9cm
The effect of "shutter shock" is somewhat visible at 1/200.

The way I understand this, diffraction is only determined by the size of the lens aperture. My point is that it begins when we close down the aperture. Therefore, if we have a super high MP sensor in the future, diffraction will be noticeable even earlier than what we currently see... In other words, higher megapixel sensors are not causing more diffraction, as many claim online -- they simply make the effects more noticeable at the pixel level.

Flawed? Certainly. Changing the aperture usually moves the focus, the only focus shift present (if any) is mine. Instructive enough though.
