Lens Impression




Blue color of the reflection of coating is impressive. As I wrote in the Company introduction page, this lens composition had been designed by C.G.Wynne in 1944 as the modification of normal Double-Gauss type. The cemented concave lenses were changed into a strongly bended single concave meniscus lens which improve the total performance within standard angle of view, and also improve flatness of center field and decreasing astigmatism. It is said that the combination of the front half of Planar and the rear half of Topogon.

This lens composition was taken over Biometar of Carl Zeiss, and Xenotar and Planar 80mmf2.8 of Rolleiflex f2.8 have very similar compositions. This lens composition is in general called as "Biometa or Xenotarr type", Carl Zeiss had been held the Patent of this design before the 2nd World War, but the production had delayed after the production of Wray Unilite lnes. Unilite and Biometar/Xenotar have different shape of the third element. Unilite has more thick concave which appeals more Gauss type charactaristics.
The description is very sharp and clear in general. In full aperture, I can see light blur around highlight part and also not too sharp around the peripheral part. But this is exactly what I like.

Portbello Market


I made first impression at usual Portbello Market. I include B/W this time.
As I took all photos in full aperture or almost full, some soft blur appears around highlight part. On the other hand, the expression of people's skin is so tender which seems to be liked by ladies. Bokeh is weak in general and seems the depth of fields appears more than f number. Bokeh itself is very straight and can not see any swirling type of bokeh.
