The lens is not so big and heavy as usually saying about it. Handheld is really possible but the fastest shutter speeds should be used. The tipical speeds for handheld shooting with this lens are 1/500 and 1/1000. Otherwise, a good tripod is required. Also, the lens has built-in hood.
Finally, it was replaced by completely newin 1999 which is a bit heavier but is apochromatic lens.
Diaphragm unit of the 9 aperture blades revision of the lens has tendency to stuck after making a shot.
The first single coated version was replaced soon by multi coated one in 1971. It is exactly the same lenses with 7 aperture blades. The finishing of these Takumars are differ from other “TAKUMAR/6X7” engraved lenses by a rubberized focusing ring. Also, the multi coated Takumar may be found with focusing ring rubberized like other later “PENTAX-6X7” engraved lenses.
|Super-Multi-Coated TAKUMAR/6X7 1:4/300||1430g||1971|
|SMC Pentax 67 1:4 300||1430g||1987|
Next revision of the lens was made in 1987. But there is something strange happened with this revision: some instances of the lens have finishing of the focusing and aperture rings as “PENTAX-6X7” engraved lenses. These lenses have 7 aperture blades as Takumar revisions while the latest has 7 or 9 aperture blades. See the images bellow for the details.
The next images are the two different revisions engraved with the same label. An attention should be payed to this label, it is exactly same for both lenses – “Pentax 67 1:4 300mm” as it usualy exists on the latest models while finishing is different. The latest revision has diphragm unit with 7 or 9 aperture blades.
