What kind of lenses does the Heliar camera use?
Later Voigtländer or its successor Cosina managed to develop new Heliar lenses for 35mm format which are much faster or have a much wider angle of view, in a wide range from ultra wide angle 12mm to telephoto 180mm. Therefore new lens designs with 6, 8 or 10 elements were derived from a completely new design of the Color-Heliar 75mm.
Can a 14mm lens be mounted on a a7ii?
My Rokinon 14mm f/2.8 super wide angle lens can be mounted to the a7II but it’s really big, especially for a camera that I bought for its small size. The 15mm f/4.5 Heliar III is the first compact super wide from Voigtländer that’s optimized for use on digital cameras.
Who was the inventor of the Heliar camera?
The Heliar is a lens designed and made by Voigtländer. It was developed in 1900 by Dr. Hans Harting, and patented in Germany (1901), Britain (1901) and the USA (1902), originally as a symmetrical 5-element variant of the simple anastigmatic and well color-corrected Cooke triplet.
How are wide angle heliars similar to Cosina’s APO-Lanthar 90 / 3.5?
Cosina’s APO-Lanthar 90/3.5 got basically the same 6-element construction. Similar constructional characteristics of the new wide-angle Heliars are 3 uncemented single-element groups close together in the front and one cemented two-element group as second group when counted from the back. ↑ Greenleaf, Allen R. (1950), Photographic Optics.
When did Voigtlander invent the Heliar lens?
Voigtländer itself created variations of the Heliar. The position of the two cemented converging lens elements could be inner or outer elements of the lens. The latter concept was taken over in 1925 from the Dynar lens to achieve a Heliar design for faster speed f3.5.
What’s the difference between the Heliar and the Lanthan?
A true redesign by Tronnier with the new Lanthan glass had better lens fault corrections, but was explicitely not marketed as Heliar but as APO-Lanthar since the Heliar’s remaining lens faults were seen as the lens’ characteristics!
