hello all,
i got this neat brass lens the other day. it had a piece of paper taped to it that said 19 inch. i did not believe that BUT when i put it on my 4x5 it measured 18 or 19 inches. not bad. it is about 11.5 cm tall and the elements are about 7cm wide. it has a water house stop. and a flange! i see two large reflections and one small reflection in both the front and rear element.
i am sure it will cover 4x5. i am going to guess it will cover 8x10 (based on the fact it is a 19 inch lens). is this a correct assumption? will it cover larger formats at infinity? what is the lens design? what performance should i expect? what would be a good guess at max. f stop? f4-f5? i do not see any "swirlies" on my 4x5. i have sold my 8x10 so i can not check that.....my new 8x10 should be arriving any day so i will be able to test that later.
there is no markings or writing to give any info about the lens.
thanks for the info.
