47mm for 6 x 9?

[steve_singleton2]

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.

[bob_salomon3]

No he used the 45 version

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

 

<p>

 

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.

 

<p>

 

As for grey.

 

<p>

 

Either our products or from other companies.

 

<p>

 

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.

 

<p>

 

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.

 

<p>

 

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..

 

<p>

 

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?

 

<p>

 

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.

 

<p>

 

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

 

<p>

 

Could you enlighten me here?

 

<p>

 

Thanks!

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.

Thanks

I looked at the coverage in the brochure.

[kahheng]

Are you saying that your brochure tells you that the 45mm APO

Grandagon specifically gives 50mm of rise and 50mm of shift for 6x9?

 

<p>

 

Did they change the formulation of this lens?

 

<p>

 

In my Rodenstock brochure of 1998, it says 24mm rise and 19mm shift

based on an image circle of 131mm for the 6x9 format.

 

<p>

 

Ok, let me clarify this with Rodenstock Germany.

 

<p>

 

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.

[bob_salomon3]

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.
