Rogonar –

 

---

The Rogonar forms a solid basis for the “first steps” in the amateur’s home lab. This lens is already a standard feature of many low-price enlarging units.

 

With 3 single elements, it has a relatively simple optical design. But when used for a smaller scale range of about 2x to 8x and a working aperture of f/11, it still offers good results.

 

Rogonar	Recommended scale range	Maximum film format
50 mm f/2.8	2× - 8×	24×36 mm

Rogonar S –

 

---

The universal lens Rogonar-S has a relatively simple optical design and so a very attractive price. But the high performance capability of this lens meets the requirements of demanding amateurs or professional labs. It is available for many different film sizes up to roll film 6 x 9 cm.

 

Rogonar S	Recommended scale range	Maximum film format
25 mm f/4	10× - 30×	13×17 mm
35 mm f/2.8	10× - 30×	18×24 mm
50 mm f/2.8	2× - 10×	24×36 mm
60 mm f/4.5	2× - 10×	40×40 mm
75 mm f/4.5	2× - 10×	6×6 cm
90 mm f/4.5	2× - 8×	6×7 cm
2105 mm f/4.5 *	2× - 8×	6×9 cm

Rodagon –

 

---

The Rodagon lens is superior to most of the conventional macro lenses in resolution power and contrast.

 

The 6 element design guarantees the resolution of the finest details while maintaining a uniformly high contrast from the image center to the the edges. As the lens is nearly independent with regard to magnification scale, top quality is ensured from mini-prints right up to high enlargements. The recommended working aperture is reached by stopping down by only 2 stops from open aperture.

 

All Rodagon lenses are equipped with an illuminated f-stop display, a practical pre-set aperture and a click-stop diaphragm which can be switched to stepless control (expect for the 180 mm lens). As an alternative, the Rodagon 28 mm is available in a smaller barrel with a 32.5 mm thread mount.

 

 

Rodagon	Recommended scale range	Maximum film format
28 mm f/4	5× - 30×	18×24 mm
35 mm f/4	5× - 30×	24×24 mm
50 mm f/2.8	2× - 15×	24×36 mm
60 mm f/4	2× - 10×	40×40 mm
80 mm f/4	2× - 10×	6×7 cm
105 mm f/5.6	2× - 10×	6×9 cm
135 mm f/5.6	2× - 10×	4×5 inch
150 mm f/5.6	2× - 10×	4×5 inch

Apo-Rodagon N –

 

---

The correction of these excellent lenses with up to 8 elements was taken to the absolute limits and so ensures the full elimination of irritating visible color fringes on high-contrast structures. All monochromatic aberrations have also been greatly reduced to give this lens type its unsurpassed image reproduction performance.

 

Apo-Rodagon N	Recommended scale range	Maximum film format
50 mm f/2.8	2× - 15×	24×36 mm
80 mm f/4	2× - 15×	6×7 cm
105 mm f/4	2× - 15×	6×9 cm

 Rodagon-WA –

 

---

The Rodagon-WA has a shorter focal length and a larger image angle and hence it achieves a 70 % larger projection area than a conventional enlarging lens with standard focal length. It is therefore eminently suitable for section enlargements on enlargers with a relatively short column. Clumsy wall or floor projections can be avoided.

 

Rodagon-WA	Recommended scale range	Maximum film format
40 mm f/4	4× - 20×	24×36 mm
60 mm f/4	4× - 15×	6×6 cm
80 mm f/4	4× - 15×	6×9 cm

Apo-Rodagon D –

 

---

Apo-Rodagon-D lenses are designed for the highest possible imaging quality for close-ups at just those scales around 1 : 1 where even the best enlarging lenses for larger scales begin to show their weak spots. Thus their typical application are transparency duplication, the preparation of internegatives and macro photography, where these lenses have an excellent performance for the recommended imaging scales. For the application on SLR cameras the Modular-Focus helical mount, available as an accessory, and a matching camera adapter are required. Furthermore, as well as for photography, they can also be used as high resolving optical systems for premium scanners.

 

Apo-Rodagon D 1x	Recommended scale range	Maximum film format
75 mm f/4	0.8× - 1.2×	6×6 cm
Apo-Rodagon D 2x	Recommended scale range	Maximum film format
75 mm f/4.5	1.2× - 2.5×	6×7 cm
Apo-Rodagon D	Recommended scale range	Maximum film format
120 mm f/5.6	0.5× - 3×	4×5 inch

Accessories: Modular-Focus –

 

---

Enlarging lenses do not have a helical focusing facility because focusing is performed with the enlarger’s bellows extension. If an enlarging lens is used as a taking lens, it is necessary to fit a focusing device. The Modular-Focus developed for this purpose has a stroke of 25 mm and offers high setting precision and stability to match our enlarging lenses’ high image quality.
