bill_bartels1 Posted September 23, 2000 Share Posted September 23, 2000 Hi,Does anyone know the image circle of the 19" red dot artar. I am thinking about a panoramic camera either 7x17 or 8x20. It would be great if my 19" artar would cover. ThanksBill Bartels Link to comment Share on other sites More sharing options...
neil_poulsen1 Posted September 24, 2000 Share Posted September 24, 2000 I have documentation which states that the 480mm, f11 Red Dot Artar has an image circle of 452mm at f16. Link to comment Share on other sites More sharing options...
carl_weese Posted September 24, 2000 Share Posted September 24, 2000 Bill, <p> I don't have numbers, but reliable sources have told me that the 19 inch artar will cover 12x20 when stopped down to f/45 or further. It should even give some room for adjustment on 717 and 820. These lenses have a lot of sample variation since many are remounted process lenses: a test is certainly a good idea but you will probably get a good answer.---Carl Link to comment Share on other sites More sharing options...
robert_a._zeichner Posted September 24, 2000 Share Posted September 24, 2000 This lens has a projection angle of 46 degrees and a diagonal coverage at infinity of 16.1" Hope this helps. Link to comment Share on other sites More sharing options...
bill_bartels1 Posted September 26, 2000 Author Share Posted September 26, 2000 Thanks to all who responded. Looks like the Artar may cover but just. Link to comment Share on other sites More sharing options...
