Rodenstock Apo Ronar f9 360mm lens

[Anton Lukoszevieze]

Is this a good lens for 8x10? Is it super sharp or little bit creamy or?
thanks

You would not find the Apo-Ronar a "little bit creamy" under any circumstances, however the 360mm Apo-Ronar is designed for 5x7 maximum, as shown on this page:

The 360 Apo Ronar just covers 8x10 with no movements.

So if the image circle just barely covers the diagonal, how does the image quality look at the corners?

Hey Dan
The Rodenstock link you posted shows the 360mm APO Ronar just covers @ inf used at a working aperture of f22/32 w/ 3mm/4mm (ver/hor) shift. I would think the corners to be acceptable given this is manufacturers information & most times they tend to be conservative @ least at this time in history. Not always the case in the early days.

If I'm reading the 360/9 Apo Ronar MTF chart posted here https://skydrive.live.com/redir?resi...33C77D1008!324 correctly, at f/22 the 8 and 16 lp/mm MTFs are under 5% 24 degrees off-axis (that's at the edge of a 320 mm circle). Look for yourselves.

The table at the top of the document recommends the 360 for 14" x 18" @ 1:1, i.e., 7" x 9" at infinity. If you want sharp images with good contrast of a distant subject in the corner of an 8x10 negative you might not want this lens. If you're going to use it for closer subjects or what's in the corners isn't really that important, it might do for you.

So I would guess this would also apply to the Red Dot Artar, with similar angle of view. Amazing how many different opinions on coverage for these len's.

In the advertisement brochure from Rodenstock for the 360 Apo Ronar the recommended format is 5x7, however in the same doc they include max shift values for different film formats. Included is 3&4 mm shift for 8X10. Essentially no shift... You could be out that much if the lens is not perfectly centred in your board. At closer focusing distances even larger formats will work [which the lens was originally designed for]. the shorter Apo Ronars perform best at f22. The lens is not flat field but behaves as such when stopped down.

So the corners should be sharp stopped down. Depending on subject matter, one could shoot with a wider aperture and intentionally let the edges go soft.

Thank you all.

I neglected to mention in my earlier post - I have a 360mm Apo-Ronar in a Copal #3 shutter. It's a beautiful lens and works wonderfully on my 5x7.
