Thanks for the reply. I was most curious since you mentioned you use Kinoton. The way I understand the HD PLUS lens is that it achieves the improved light by having the acceptance angle conform to light coming out of the lamphouse so the lamphouse reflector is a major element in the whole process.

I have received a report of someone using the Strong Super Lume-X lamphouse and the light improvement was substantial, particularly in the corners...the natural hotspotting was substantially diminshed.

I have used UltraStar primes with the BlueStar as well as the Schneider Super Cinelux line of lenses with the Blue Star and in all occurances it was a great success. Unlike other anamorphics, the Blue Star doesn't seem to cost you any resolution. It is simply great.

I will agree that the Schneider Integrated anamorphics are also quite good...I wish ISCO would also make their integrated anamorphics as attachments rather than "integrated"...then make a Blue Star with it.

The match of lenses and reflectors does make a significant difference in SYSTEM performance. Not just alignment, although that can make a huge difference, but in the components and how they match up as well. I have not had the opportunity to "play" too much with the Kinotone stuff, so I am not familiar with its optical characteristics. Guess I better find one somewhere near me and explore a bit. Any volunteers?

My results with the PLUS lenses have been very positive, overall. I can only speak for what I've seen and worked with, of course, and that goes for my equipment and a little of the competition that's out there.

I have yet to install a PLUS in place of a standard Ultra-Star * HD and not see an improvement in performance, both in overall light throughput and especially in distribution. By fine-tuning the system's primarily alignment, whatever gain I get from just replacing the lens can be further improved, sometimes by a LOT. Some of the numbers in some places have been really exceptional.

What I notice with the PLUS is a significant improvement in the center, and a BIG increase in distribution, both on the sides and in the corners of the picture.

Now, that's mostly using US-designed optical systems and, again, I've not had the opportunity to test in a Kinotone-equipped house.
