Tamron 1:5,6 f=300mm model CT-300




Tamron 1:5,6 f=300mm BBAR MULTI C (Adaptall model CT-300) is a telephoto lens for 35mm cameras. Has Adaptall mount, which allows you to install it on any systems of 70-80s.

Produced from 1976 through 1979. In 1976, the company has provided a new line of Tamron lenses with interchangeable mount Adaptall. In 1979, because the release of a new line, it was replaced by the Model 54B, which had an additional optical aberration correction unit (2 elements), making new lens harder.

Optical design — 4 elements in 4 groups.

Near the aperture ring is a switch "A/M", which switches the manual and automatic iris control. Apparently, you can check the depth of field.

Such a switch I have seen on the medium format CZJ Sonnar 180 / 2.8. There is also version of this lens with a silver barrel. In general, I want to mention a convenient and pleasant design lenses Tamron 70-80-years. Says that the director personally supervised the lenses design, as set performance aesthetics and ergonomics in the first place.

Tamron 1: 5,6 f = 300mm Sharpness

At wide-open lens has portrait sharpness, there is small spherical aberration, but for such focal length, I think the sharpness is quite normal.Tamron f/5,6 f=300mm CT-300 sample photos

f/ 5,6

When you close the aperture, aberration disappears and sharpness increases. There is narrow DOF at wide-open, feels like the 100mm at aperture f / 2.8 lens, but to catch the green dot focus confirmation is more difficult because f / 5.6 is darker.

The longer the focal length of the lens, the more it compresses space. At the 300mm focal compression becomes clearly visible. Therefore, distant objects that are the subject of getting closer. Also compressed perspective, the usual urban views seem unusual.Tamron f/5,6 f=300mm CT-300 sample photos
