I don't believe the new Nokton 1.2 is actually going to be any smaller, rather, what I've heard is that is was actually an error in the specs where the measured the old one with the hood and the new one without, resulting in a difference of a few millimeters.
Given they had to change the optical design slightly due to no longer being able to get one of the aspherical elements, there is a slight reduction of weight, but again, its just a few grams difference from what I recall reading.
Point being though that the new vs old lens is really going to be nothing more than an academic difference in terms of size/weight and not something you'd be able to really tell a difference in.
Now as for price, which is yet unknown, who knows if its going to cost more or less than the older version, likewise, optical performance differences are not known.
Could be a cheaper and better lens, or could be more expensive (which stands to reason as few products are going in price in this global economy)
Personally my guess is that the optical performance isn't going to be as good either. Reason being the change in design is due to a sourcing issue with one of the elements, not a redesign to improve the performance.
Of course it could very well remain about the same as well, but I just haven't found any of Voigtlanders new designs to be that good.
Nokton 35 1.4 for example, or the 28 2.8, both are at nice price point, but the optics are rather lacking.
The older Ultron 35 1.7 for example was a much better lens, as was the older Skopar 28 3.5 than the new 35 and 28's respectively.
Basically it seems with CV for the whole, their older designs, which are out of production, such as the Nokton 35 1.2, Nokton 50 1.5, Ultron 28 1.9, Color Skopar 28 f3.5 and Ultron 35 1.7 are all the best optics they have produced.
Exceptions of course are the CV12 and 15's which are a little better optically in addition to being now rangefinder coupled.
The 75 2.5, another decent but discontinued design is another example, being replaced with the 75 1.8, which cost twice as much, is much larger, and doesn't compare optically at all. Granted its called a "portrait" lens, and it could be said its very strong field curvature and off center performance is on purpose.
To some degree, I feel like its sort of a cop out on VC's part, producing lens with lots of issues such as vingetting, distortion and field curvature and saying they did it on purpose to recreate some older optical designs, such as an early Leica 35mm pre-asph Lux.
Thats all fine and good I guess, but you've got to wonder why recreate old and flawed 40 year old designs when modern optical design allows far better optics. Leica, Zeiss etc all have improved their designs over the years with the modern ZM and ASPH lineup (50 ZM Sonnar being an exception) and it seems VC used to be working that way as well with the Noktons but now they've taken a step backwards.
Or at least thats my thoughts on the matter.
