Coverage of 19 inch Red Dot Artar?

[Willie]

Friend picked up one of these in an Ilex shutter.

Anyone know the coverage of this lens?

He is getting back into LF with an 8x10 Deardorff for the lens.

I've got one on my 8x10 'dorff. It's a fine long lens with plenty of coverage

Works fine for 11x14 also.

Works on my 8x20 and 14x17.

One thing to be aware of is that most Artars originally came in barrel mounts. Ones mounted in shutters were usually, but not always, custom lens mounting jobs. Another LF photographer that I was friends with picked up one that was mounted into an Ilex shutter (No. 5 but I could be wrong). It performed only mediocrely for him. When he placed it next to my barrel 19" Artar, it was obvious that the spacing of the front and rear groups of elements was significantly increased. Fortunately it was an easy fix for for him for under $200.

I had SK Grimes put a 19” Artar into a Copal #3S and it’s excellent on my 5x7. A well known Chicago photographer used one on a 12”x24” camera…..

19" Goerz APO artar is a classic and excellent "tele" for 8x10. Easily covers 8x10 at infinity with more than adequate camera movements. The classic partner is a 12" f6.8 Dagor and 14" Kodak Commercial Ektar. These three plus a 155mm Gradagon (BIG) and 250mm Wide Field Ektar made up a nice lens set for 8x10.

Difficulty with these older lenses are their shutters. Some Ilex shutters are SO wore out in desperate need of their wore out parts replaced and properly serviced. C-L-A will NOT do.

If your APO artar cannot resolve to the degree as posted in this example that sample APO artar has a problem.

That said, a good APO artar will equal any modern lens for resolution-definition or similar APO process lens at f16 to f45. They are lower contrast compared to modern multicoated offerings of similar focal length. Ones in barrel have a nice round iris, coupled with a Sinar shutter makes a good combo.

They remain one of the all time fave longer than normal focal length lenses.

To second Greg: I got mine front-mounted as a barrel lens into an Alphax #5; a great, easy option and, if the mount is slim, the image circle doesn't suffer significantly.

Depending upon when Grimes did the work (as in more recently) it must have been a shutter supply issue because Grimes put my 19" Red Dot Artar into a standard Copal #3 shutter probably 10 years or more ago. Agree it is a great lens with tremendous coverage. I use it on 12x20, 8x20 and 11x14 as well as 8x10.
