Hi Dennis. Thank you for posting your nice designs. I espescially like #31 since you are using different grey tones there. In my taste it makes the logo more dynamic and vivid then only black and white. I'm not yet sure if I like the mixing of bold and normal font, in the moment rather no. Also it would be nice to see some more apperture symbols from you.
I like the additional half ring you added on the outside. Always when I look at your logos I'm a little irretated by the elipse on the uper side of the aperture (I assume it is a reflecition on the lense?). Probably you can show another way the roundness of the lense.
The new designs with changed reflection I like better then the old ones. Of the three I like #115 best (even though #114 is very close). Can you please upload #115 with white background.
The added color I'm not so sure of. I will ask for some more opinions. For me I prefer the black and white version for this logo.
Regarding the new sorting strategy, please see my comment in the general section.
