Apo-Sironar-S –

 

---

It provides an image angle of 75° and permits even more generous camera movements, than they are required for perspective correction in architectural and product photographs. Furthermore, the Apo-Sironar-S with a long focal length in relation to the image format, is ideal for the application as a “telephoto lens”, because of studio and technical cameras (if required with an additional bellows) permitting particularly large bellows extensions. Therefore problematic telephoto constructions with a barlow group, which tend to create color fringes and provide the advantage of short length only for use with cameras without bellows, are not necessary any more.

Apo-Macro-Sironar –

 

---

In the close-up range, at scales of around 1 : 1, the quality of lenses optimized for larger distances falls visibly from the usual standard of performance. Here the Apo-Macro-Sironar lenses come into their own for imaging scales of 1 : 5 and greater.

Apo-Grandagon –

 

---

The Apo-Grandagon ultra-wide angle lenses give you the freedom to find new and appealing views in product photography. But new standards in freedom of movement for architectural and industrial photography are also offered by these The Apo-Grandagon ultra-wide angle lenses give you the freedom to find new and appealing views in product photography. But new standards in freedom of movement for architectural and industrial photography are also offered by these outstanding lenses with a usable image angle of 120°. The Apo-Grandagon 55 mm f/4.5 even covers 4 x 5 in. sheet film which is most popular in demanding landscape photography.

 

Apo-Grandagon	Max. recommended filmformat
35 mm f/4.5	6×9 cm
45 mm f/4.5	6×12 cm
55 mm f/4.5	9×12 cm / 4×5 in.

Grandagon-N –

 

---

The Grandagon-N with its wide image angle of up to 105° can really display its strengths in wide views in cramped conditions, e.g. in architecture or industrial photos or in panoramic views.

 

Grandagon-N	Max. recommended filmformat
65 mm f/4.5	9×12 cm / 4×5 in.
75 mm f/4.5	9×12 cm / 4×5 in
90 mm f/4.5	13×18 cm / 5×7 in.
90 mm f/6.8	9×12 cm / 4×5 in.

 

* The first number is the diameter of the rear male thread for fixing at the lens, the second number is the diameter of the front female thread for adding another filter or a lens hood.

Accessories: Center filters –

 

---

For critical shots (e.g. with areas of uniform brightness towards the image corners) with lenses with an extremely large image angle, the physically inevitable light fall-off can become a disturbing element. This can be avoided by using the Rodenstock center filters recommended in any case the image circle is used right up to its margin. The Rodenstock center filters are available for the Apo-Grandagon and the Grandagon-N lenses of all focal lengths.

Accessories: Focus-Mount –

 

---

Using digital lenses on cameras without bellows such as panoramic or shift cameras requires the use of a focusing facility. For this purpose we developed the Focus-Mount that can be combined with all Rodenstock lenses in shutter size 0. Existing lenses can be installed at a later date.
