Removing the metal push-on lens cap, we can see the front element is very deeply recessed. There were a very wide variety of mounts made for this lens, so with an appropriate adapter, it could well be possible to use it on whatever camera system we have. Other camera bodies from other marques will behave differently. Then take the shot and the lens will stop down correctly.
This briefly stops down the lens to whatever aperture is set, takes a meter reading and sets the shutter speed accordingly. To obtain the correct exposure, press the green button on the back of the camera. After that, on the K-1 manual exposure mode is set. There are no electronic contacts, so the K-1 immediately asks what the focal length is, the information being fed to the SR (Shake Reduction) system that is built into the camera. So that may not be too much of a disadvantage. AF is, of course, absent, but then again many macro subjects favour manual focusing even with an AF lens. Vivitar Auto Macro 55mm f/2.8 Handling and FeaturesĪ multicoated manual focus macro lens with continuous focusing down to life-size, or a magnification of 1x or 1:1, is an attractive proposition. So far so good, let's see how it works out in practice.
#Vivitar lens serial numbers serial number
This gives us the maker (28 is Komine), the year of manufacture (7 could be 1977 or 1987), the month of manufacture (11 is November) and the serial number within that month (929). From the serial number of 28711929, the lens falls into the years where the numbers can be deciphered. Having been given the loan of a boxed example of the lens that has hardly been touched since new, it's an interesting chance to review it using the Pentax K-1 36mp full frame DSLR. There are some lenses that achieve a certain legendary status over the years, and the Vivitar Auto Macro 55mm f/2.8, made by Komine, is probably one of the better known.
