Facing east with the early morning sun behind the planter. Double test, new lens and tried stand development for the first (and probably only) time.
M4-2, Voigtlander 28 2.8 Color Skopar V2
TX400, Rodinal 1:100:
Fred, my VM 28mm 2.8 also arrived in the meantime.
What I was wondering about, did you compare the Leica and the Voigtländer lens with regards to flare resistance?
Most of the Leica lenses badly disappointed me in that category and this would be very important to me in a lens like this.

Earlier, I mentioned that usually Leica lenses are not as good at resisting veiling flare compared to Voigtlander lenses. But, when I compared the Elmarit and Color-Skopar lenses for rendering, I found situations where veiling flare was visible with the Voigtlander lens but not with the Leica lens. I posted a comparison at the end of this forum post: https://www.fredmiranda.com/forum/topic/1819458/3#sun.
(I didn't use UV filters for both lenses.)
However, I believe this is uncommon and might be due to the low position of the sun. I tried to recreate the same effect under harsh lighting conditions, but I couldn't get much veiling from the Voigtlander lens. It seems to be very effective at preventing ghosting flare.
I owned the previous gen Leica 28 Elmarit Asph, and found it was the one Leica lens that actually was fantastic at handling flare. Which was what I expected from all Leica lenses given their price point. But nope, out of all the Leica glass I own, only the 28 Elmarit Asph met expectations w/re. to flare.
Some similar images as yesterdays post but went to my standby of Tri-X developed in a 50:1 dilution of Rodinal. The 100:1negatives were over developed and thick and didn't show the little Color Skopar in it's light. Hope these are a little better. Taken with a M4-2, 28 2.8 Color Skopar V2, TX400 @ ISO 200:
It had great flare resistance but it also had the funky hood that would pop off at the most inappropriate time or it was used as a handle to detach the lens from the camera and eventually unscrewing the front element group.

I never, ever, not once, had it pop off! You know I love you - as a brother - but this does kinda sound a teeeensy little bit like user error.
Now that stooopid rubbery flap lens cap? That was a miserable piece of 'oh you lost it, that will be $80' design.

Mostly it popped off just as I was putting in the bag, never when I was actually using it. I was good with the little rubber hood. My first one came without one and a local shop was clearing out their Leica gear and they just happened to have one in a drawer. It was either in the bag or shirt pocket any time the lens was in use.There were a couple of threads on LUF about users unscrewing the front element but careful folks, like you (an me), know to always hold the lens by the body not the hood.
I'm liking this little lens. Makes that Biogon I owned once upon a time, look like a Noctilux!
Interestingly the design of the aperture ring is almost identical to the Minolta 40mm 2.0 M-Rokkor (size is, too).
A very basic lens design question... the CV 28 2.8 has relatively heavy vignetting. And I notice how small the diameter of the front element is. Would it have made any difference if they just made that bigger? There seems to be plenty of room in the lens housing w/o changing filter size etc.

I am pretty sure that would have helped but making the elements bigger would have probably driven up the price to be the same as that of the 28mm 2.0, making this one harder to sell.
Personally, I wish it was +$100 and -1 EV vignetting, but Cosina didn't ask me
Just for fun, I dug out the kitchen scale and decided to weigh both M4 with the 28 2.0 Ultron ASPH V2, 28 finder, loaded with a roll of Tri-X and the M4-2 with the 28 2.8 Color Skopar V2, 28 finder and also loaded with a roll of Tri-x:
M4 combination: 903 grams
M4-2 combination: 745 grams
Five ounces isn't a lot but it does make it easier to carry around!

Beautiful photographs of lenses with the size I like. What is your M collection now?
I always try not to be that much of a collector actually.
That being said I do have of course acquired too many M-mount lenses:
Laowa 5.6/9
Zeiss 8/16 Hologon
MS-Optics 2/24, 1.4/35, 1.0/50, 2.4/135
Voigtländer 4.5/15 II, 3.5/21, 1.4/21, 2.8/28, 1.2/35 III, 1.4/40, 1.5/75
Mr. Ding 1.1/50
Leica 2/90 pre-Asph
Hologon is for sale if someone wants it, also not sure if I will keep both 21s.
The M-Rokkors are not mine, a reader sent them to me for reviews.

Are you going to keep the 28 Color Skopar?
I like mine and can see it being a regular user. The only film I use is Tri-X and the only digital camera is a Sony A7II that's used exclusively for scanning. The vignetting doesn't bother me because it reminds me of wide angles from an earlier era, much the the SC Nokton. I have also owned and like the 28 Elmarit-M ASPH but actually prefer the images from Color Skopar.
