47mm for 6 x 9?

greenspun.com : LUSENET : Large format photography : One Thread

For architectural shots with an Arca FC 6 x 9, I need a wider lens than my 65mm Caltar. Since it needn't cover 4 x 5, I'm assuming that a Rodenstock 45mm (unlikely used), or more likely a used Super Angulon 47mm non-XL would offer the best combination of quality and value. Correct assumption or is there another choice to consider?

The 35mm Apo Grandagon as well as the 45mm will more then cover 69cm.

I have a Schneider SA 47mm (non-XL) and 6x9 roll film back. While it will cover 6x9, the image circle doesn't seem to leave much room for movements.

I remember seeing or hearing about a review of one of the Rodenstock lenses Bob mentioned in View Camera Mag in the past year. I believe the review was done by Norman McGrath. If I remember, he specifically tried the lenses on an Arca Swiss 6x9.

No he used the 45 version

I'd get the 47mm SA XL anytime. Why?

The 47mm non-XL and the Rodenstock 45mm will not give you much movement at all. I shoot 6x9 for the same kind of photography that you do, and I've tried both these lenses on the job. They just don't work out for this kind of work because the circle of coverage is fairly limited in that format. You'd want a fair amount of shift ability under most circumstances, and in that focal length, only the 47mm SA XL cuts it.

If you want to save some money, try to get it as a grey import from Badger Graphics or something.

The 45mm Apo Grandagon on 6x9cm allows for 50mm of rise and 50mm of shift. In many cases this is more then many 6x9cm cameras may have and even more then many folding 45 cameras have.

As for grey.

Either our products or from other companies.

In our case, as well as in many other companies in the U.S., the warranty on the grey product is only available through the importer of the grey item and may be different then the US warranty.

In the case of all Rodenstock lenses there is a lifetime warranty on the glass if it is imported by us as well as a 3 year warranty on the shutter.

The International warranty is less comprehensive and is not honored by the Rodenstock service facility in the U.S. unless the accompaning bill of sale is from a dealer outside the U.S..

If the bill of sale is from an American dealer then no warranty or service is available except from the dealer who sold the lens.

How do you figure 50mm of rise and 50mm of shift on the 6x9 format with the 45mm APO Grandagon?

The image circle at infinity as given by the 1998 Rodenstock catalog at the "recommended working aperture" (they are not clear as to what it is here, but I presume its f16) is 131mm and the catalog points out that you should get no more than 24mm of rise and 19mm of shift in the 6x9 format.

How do you calculate 50mm of rise and 50mm of shift?

Could you enlighten me here?


-- K H Tan (kahheng@pacific.net.sg), April 09, 2000.


The test aperture used for the APO Grandagon is f11 (from the big coverage diagram at rear of the catalog) and Rodenstock suggests that these lenses should be used at f8-f11.

"How do you calculate 50mm of rise and 50mm of shift?

I looked at the coverage in the brochure.

-- Bob Salomon (bobsalomon@mindspring.com), April 09, 2000.

Are you saying that your brochure tells you that the 45mm APO Grandagon specifically gives 50mm of rise and 50mm of shift for 6x9?

Did they change the formulation of this lens?

In my Rodenstock brochure of 1998, it says 24mm rise and 19mm shift based on an image circle of 131mm for the 6x9 format.

Ok, let me clarify this with Rodenstock Germany.

This is highly interesting.

I can check the latest brochure when I return to the office tomorrow.

Another reason for going with the Schneider 47mm F/5.6XL Super Angulon over the older version is that it produces a "sharper" ( more contrast & resolution) image. That lens and the Apo grandagons are worth looking into. You'll be surprised what you find in the used marketplace. I tried a 47mm XL for a month and returned it because it was too wide for my tastes.

-- Ellis Vener (evphoto@insync.net), April 10, 2000.

The latest brochures, both dated 8/98, for the Garandagon N and Apo Grandagon have corrected the figures in the older brochure that I have at home. On 69 with the 35mm the range of movements is 20 and 15mm at f8 45mm the range of movements is 24 and 19mm at f11 55mm the range of movements is 40 and 31mm at f11

Sorry for quoting the older brochure.
