    I have the chance to get a very nice looking 19 inch Red Dot Artar in an Iilex shutter but really know little about this lens.

    I'm considering it for 5x4 only so want to know if it will be a sharp lens for that format.

    Any information will be appreciated.

    Steve, it will cover up to 11x14. So 4x5 is no sweat. It is razor sharp.

    I hope you've got a lot of bellows draw on your 5x4....

    ..a real lot :sad: With a 12" lens on my 4x5 speed graphic, my bellows is maxed out.

    same with a 5x4 Wista 300mm (12") is the max unless it's a Tele lens which has a much shorter back focus.

    red dot artar, 19 inch

    whoa: a 483 mm lens on a 4x5 would require one hell of a bellows.

    Fyi we heard from the Playboy photographer last week at the View Camera
    Conference in Chicago.

    They used red dot artars and Commercial Ektars, because in their opinion they were not as sharp as modern lenses.

    I have no opinion on who's the sharpest, depends on what the need is.

    check the bellows first. you would need at least 500mm draw, maybe 530.

    {echo need for sufficient bellows draw}

    I have a 16 1/2" Red Dot Artar, also in an Ilex #4 shutter, and like it a lot. Carol Miller just did a CLA on the shutter, and I'm anxious to put the lens to use again.

    Again, I am shocked, My choice for nearly 50 years was Red Dot Artars and they certainly were not chosen because they were soft/sharp! Me thinks something is mistakenly wrong about this statement.

    I have not used an Artar or a Ronar focused at infinity where the focal length was much less than twice the long side of the negative. For example, in 4x5 I would use an 8 1/4 inch (210mm) or larger; for 8x10, a 19 inch (480mm) or larger, etc.

    If you stop down to f22, or less, you probably can use shorter focal length lenses and I am not sure that twice the short side of the negative wouldn't work as well as a minimum length. But, I haven't tried that, so I can't say.

    Given the limitation in focal length for the format, I can't see much difference between a modern lens and an Artar or a Ronar in the same focal length. The only concern being having enough bellows extension for the longer focal lengths.

    For focusing at distances shorter than infinity, you can use shorter focal lengths for a given format. I haven’t tried it, so I can’t say how much shorter, but, since you would be expanding the image circle, you would be increasing the diameter of the distortion free center. That is, after all, how these lenses were designed to be used and in that use they were described as having “zero distortion”. That ought to be pretty sharp. If you look at the old brochures, they were rated for the size negative they would cover, without movements, at 1:1. The 19" Red Dot Artar was claimed to have zero distortion for up to a 20x24 negative.

    If you need a long lens in your format and you are not bothered by a slower speed lens, then an Artar or a Ronar will get you something very sharp with excellent color and contrast for less cost, bulk and weight. Just remember that, if the lens is in a barrel, the cost of mounting it in a shutter is not cheap and price it accordingly.

    It would be an excellent lens on an 8x10---a classic! I have one and it is as sharp as they come. The problem with using one on a 4x5, as others have pointed out, is the need for bellows length which most 4x5s don't have.

    Beside the bellows issue the lens may be too big/heavy for the front standard of a 4x5 camera.

    I've owned and used Red Dots since 1973 and the images have satisfued the most demanding of clients. I have owned the 8 1/4 AND 16 1/2 but sold them but still use the 14 and 19 with excellent results.

    I'd think it depends on the camera, I regularly use a 360 5.6 componon (monster, 3 1/2# enlarging lens) on my Omega 45d with a front mount packard, you do have to make sure you lock down the front standard, but it works wonderfully. (just wish I had about 4" more bellows)

    You need to make sure your lens board can hold a lens of that size and your front standard can hold a lens of that weight.

    I have an old Cambo 4x5, and can get about 30" bellows extention, however depending on what camera you have...you might be limited.

    If you decide not to get the lens...let me know who's selling it because I could use it on my 8x10 and 11x14!

    Um, er, ah. A 19" lens needs about 19" of extension to focus to infinity, about 21" to focus to 1:10.

    FWIW, I shoot a 19" (that's 480 mm) Apo Nikkor on a 2x3 Speed Graphic, a short little camera of nothing at all. Chiller, if you must have that focal length on a 4x5 camera that, like my little Graphic, just doesn't offer the extension needed, use two 4x5 cameras. See the DIY section's sticky "this is my camera wot i built myself, i did" thread for more info.
