Voigtlander 28/2.0 Ultron Asph. VM Mk2

[sergun80]

To add to the above I have to differ... certainly not all lenses perform equally well at f8. Many lenses old and new can perform well at f8 but there are a few that perform exceptionally well. That also applies to wide apertures. The ancients do very often produce beautiful Bokeh in part due to round multi bladed iris. Leica lenses generally produce fantastic skin tones and the focus roll off is hard to duplicate.

I'm interested in your Industar. There are many LTM thread lenes I would like to explore. Please post a photo that expresses what you like about it.

I don't use any of the photo apps. Not impressed with Intagram. Can anyone suggest one that does not degrade the quality significantly?

vm 21/3.5 / f8 I specifically removed the grass from the corners. Covers well/very well.

And that is with a Lumix S9? So this shot has a slight crop then ? The 21 looks like a good compact contender for use with some Lumix cameras. I still have not pulled the trigger on ordering a 28mm color skopar. Had hoped to test one first.

Yes, S9. Nothing is cut off. I'm waiting for someone to try the 28 Scopar on Lumix. )

Appreciate the sample photo. Looks good at f8. You have encouraged me with your 21mm photos... Do you have any photos taken at wide apertures? I'm sure the quality will be diminished but it would be great to see what it looks like at 3.5 on your S9.. I have found a dealer that has the 21mm in stock so I hope to check it out this week. . They don't have the 28mm f2.8 Skopar yet but look forward to testing one when available.

I did some test shots at a dealer that let me try the 21mm f3.5 color skopar II out in the shop and found the S1RII worked pretty well with it. I did not have a controlled area or any test charts but it looked much like I had hoped. Close focus it falls down a bit as there is focus shift center to edge wide open. I used an LLL M to L helicoid adapter and when going beyond the lenes normal minimum focus the issue becomes much more pronounced. This test and Sergun80's photos on his S9 and 21mm gives me a lot more faith that the 28mm f2.8 Skopar might be an ok match with S1RII as well.

Having spent more time with the Voigtlander 40mm f1.4 Nocton Classic VM I have to say this lens is performing very well on the Lumix S1RII. It has given me the confidence to purchase the Voigtlander 28mm f2.8 Color Skopar II VM. Both of these lenses are now the most used lenses I have out of about 25 lenses that I use from various manufacturers. Mostly these consist of Leica Viso and SLR adapter lenses... This is due to the size and weight of the 28mm and 40mm. I also like the vintage look at wide apertures. These two do not perform in the sharpness department compared to my Sigma Contemporary 65mm f2 but I would think they are similar in performance when using the two Voigtlanders on Leica M cameras.

I have not done direct comparisons as yet between Leica and the S1RII cameras.

Not all Panasonic sensors are a good match. My old S1 did NOT perform well.

Have a look at this link that has some tests on the 28mm on S1RII:

Ran out of editing time... I prefer my 40mm F1.4 Nocton Classic VM over my 45mm Sigma Contemopary.

 

[Jonathan-Mac]

Last year I ordered a Lumix 50mm / F1.8 first.
But found out already within the shop by some test images, this Lumix 50mm copy was faulty / had problems (a real "lemon").
Only "this copy" - as I didn't believe the found errors was normal. Give the advise to shop employees to send this copy back to Panasonic.

So even didn't take it home. Leave it in the shop and ordered the Sigma 50mm F1.4 DG DN | Art.
The Sigma 50mm F2 DG DN | Contemporary was introduced a month later or so.
Otherwise it could be possible that I had chosen that one ??

But no regrets. I am very happy with the choice of this F1.4 lens. A kind of love-hate feeling.
Love the quality of general sharpness already wide open & bokeh.
Nice bokeh, not only in the background blur, but also in the foreground blur.
Older lens designs, when having a nice background blur, mostly it is not nice within the foreground.
(A lens with undercorrected spherical aberration is associated with a smooth background blur and a harsh foreground blur;
the situation is reversed for a lens with overcorrected spherical aberration.).

I do use this prime specially for the fast openings "only". So aperture values between F1.4 and F2.8
(Could even be that I never used it at smaller aperture openings above F2.8 ?)
I love the high mechanical build of the lens, and completeness of functions (e.g. the separate aperture ring).

The “hate” feeling, is the big and bulky size.
Other negative aspects as e.g. CA / LoCa at wide apertures, distortion. (Knew that already before buying).
Most fast lenses do suffer by these errors in more or lesser degree. (Or have to invest in far more expensive lenses).
Bother not that much for the kind of images / subjects I use this lens. As it can be corrected in post.
(Balance between costs and "overcome" lens errors).

Keep in mind, perfect lenses don’t exist. In one way or another there's always a drawback.
If it is not by pure optical means, it is by weight and size, or e.g. manual focus vs. AF.
-

The copy of the Lumix 50mm f/1.8 that I was first given after returning my original copy for blue fringing, was absolutely terrible. At f/2.8 it was nowhere near as sharp as my original copy wide open, so I had to return that. The replacement copy is every bit as good as my original and very sharp even wide open.

The Sigma 50mm f/2 DG DN is also excellent, it really feels like a slightly longer version of the 35/2.
