| Howdy from an LF newbie. Is there a difference between the Optar 90s with and without the W.A. marking? Is the coverage ok on 4x5 with this lens? I didn't find much info in the faq on this lens. Regards, Roger |

The W.A. Optar/Raptar are F/6.8
and the one not marked W.A. should
be a F/4.5 Tessar formula that covers
2*3. The wide angle does cover 4*5. |

It is marked f/6.8. but not W.A. I do see an image on the entire 4x5 GG but I thought I would ask since I am entirely new to this format. |
