    Enlarger focusing issues

    Sorry for such a newbie question. I Have an old Omega D enlarger and attempted to make my first print from a 4x5 negative and cant seem to focus the image on 5x7 paper. Is this normal or am i just missing something? I cant seem to focus it on 8x10 paper either! I can only print 1/4 of the negative on 5x7 paper. The bellows move freely and the head is also not restricted but still i cant focus the negative unless im printing larger than 8x10. I have the condenser in top position as the enlarger requires and im using my 135 lens as required. Thank You.

    Hi, make sure you are using a 2.5 inch or taller cone, instead of a flat board.

    The older D's had fixed condensers in three sizes. Make sure your fixed condenser houses the 6 1/2" lenses.

    Jon, Thanky you for your reoly. Im new to this and have no idea what a 2.5 inch cone is or a flat board. This is my first try at large format and with this enlarger.

    Rick, Thank you for your reply. I im very sorry but i have no idea what you mean. The enlarger states variable condenser and says to put it in the #1 position-slot and thats where it is now.

    Hi, the concept is: the farther the lens is away from the negative, the closer the image will focus. Therefore there are different mounting cones/boards for the lens to attach to the enlarger. So, is the mounting board that the 135mm lens attached to cone shaped or a flat one?

    Its flat. When i received the enlarger the person gave my 3 Fuji and Nikkor lenses and told all i have to do is use the 50 for 35mm, 80 for 120 and 135 lens for large format. I guess there was more i needed to know than he told me.

    Yes, as you found out, you need the cone for the 135mm, or it won't focus close enough. You can look for a 2.5 inch cone on ebay if you do a search on "omega cone" or something like that. Or put a wtb (wanted to buy) ad here on the apug classifieds.
