To complete the kit accompanying the paternal SP500 after 55mm and 135mm , the youngest: a wide angle, 35mm. 35mm, it is not very wide angle, but it is a focal length that I like because, unlike 28mm, deformations straight lines (barrel effect) are not too pronounced. Practice, especially for photos of the building.
- Type: Fixed focal lens manual
- Manufacturer: Asahi Pentax
- Model: Super-Takumar 1:3.5 / 35
- Focal Length: 35mm filter holder
- ;:
- 49mm Aperture: f/3.5 to 16
A small feature of this range of objectives: the objective of medium length is physically longer than the general angle. Pictured from left, they are focal increased: 35, 55 and 135mm, left to right. This is not the case with ranges latest: hunting millimeter and progress of optical helped shorten the 50mm, while the large angles are nearly incompressible: the distance to the film being in any way higher than their focal length, they contain necessarily divergent lenses to compensate for this difference. That is why the goals most compact frame Pentax are now 40mm: the shorter focal length for which we can do without negative element in front of goal.
This is not troublesome for the money by cons for SLR APS-C is a bit annoying, since the objective corresponding to a 50mm would be 28mm, which one would like that it is the smallest (and most open) possible ... No simple remedy to this concern, but much closer to the front of the sensor housing, thus eliminating the compatibility of these cases with optic old - a strong point of Pentax in the heart of its marketing communications ...
