Red Dot Artar 14" f9 at Infinity?

[neil poulsen]

I know that when properly stopped down, a 355mm G-Claron behaves well at infinity.

Can the same be said of a 14", f9 Red Dot Artar?

For which format, Neil?

[neil poulsen]

Primarily 4x5. A bit of 8x10.

Don't have to stop it down much for the beauty at infinity...the lens is designed for it. But not a whole lot of wiggle room for 8x10.

[neil poulsen]

That is very nice. Weren't they optimized for "near" distances? I've heard that they were a choice lens for product work.

I just purchased one mounted by S. K. Grimes in a Compur 2 shutter. It was listed for a very reasonable price on eBay, and it was described as being in excellent condition. I have a feeling this lens will be a gem.

For my use of 8x10, not much wiggle room is needed.

[Vaughn]

Not the "Red Dots". They have been optimized for far distances. And I will assume the S.K.Grimes knew how to space the elements properly in the shutter to insure that.

I use the 19" and the 24" Red Dots for 8x10 and 11x14 for landscape work -- sharp as a tack. No shutters like you lucky dog!

I'm kind of stunned not to have known that. Makes me wonder about past buying habits, etc.

Thank you for correcting my false impression.

From what I have read, only the 'pre-RD' Artars were optimized for closer focusing than infinity.

So are the G-Clarons, they still work fine at infinity. L

...so if I were in the market for a 450mm Fujinon-C, but my current needs were for 5x7, then I might be at least equally well served by a 19" Red Dot Artar?
