I have all three of the following:
Color Skopar 28mm F3.5
Ultron 28mm F1.9
Biogon 28mm F2.8
All three of them are unique in their own ways.
The skopar is really compact, images are sharp, contrast is just right.
I do not find it overly constrasty.
It's only half the size of the Biogon 28.
Built however is excellent. It's a solid little lens.
At F3.5 max, it's really good as a day time lens.
No exactly the best at night time street shooting where an F2 is more useful.
The Biogon is best built of the three.
It's performance is better than Ultron.
But only slightly better than the skopar.
The Skopar in good hands can yeild excellent results.
I do not think there is much room for improvement.
The letter inscription is done well and nicely.
With 1/3 stop increments, if your body is a Leica, subtle 1/3 stop is useful.
If I am going on vacation, the Skopar is wonderful to have around.
Lastly, the Ultron 28mm F1.9
This lens I had the longest.
It was the 2nd lens I got for my RF system.
If anyone tells me, they are going to have only one 28mm,
this is the one I recommend.
It's one full stop faster than the Biogon.
Forget about the F1.9 thing, think of it as a F2 lens.
It handles flares really well.
Lens barrel construction is not as good as the Biogon.
But still it's good, especially the black version.
The hood is nice, but the cap is esay to lose.
At F2, images have less contrast but still totally acceptable.
Here are some samples of the three:

Conclusion:
The Biogon is the zen of three lenses.
Everything in perfect balance.
The Skopar wins my award for compact, sharpness, I love this lens.
The Ultron is big, and stretching it a bit.
Still kudos to voigltander for a making a F2 lens for budget people.
Well, what you pay is what you get, the price of these lenses are a pretty good indication of what their designer think they are worth. Just think about how a Summicron 28 F2 is worth, then understand these are excellent lenses with good costs/performance ratio.
Still, any one of these lenses will blow any DSLR 28 zoom away and wins hands down.
