(We have written of the Tokina zoom before, but in that blog we were playing with removing the rear lens assembly. This blog will be different.)
This RMC Tokina 80-200 mm f/4 lens was purchased with another 80-200 mm zoom. It is larger and heavier because the other lens is smaller in aperture. They are both push-pull designs.
The lens stays the same length when zoomed. Both lenses stay where they are put, even when pointed up or down.
The Tokina does not focus particularly close. It is certainly close enough for humans, not quite so stunning for shooting butterflies on flowers. Of course you could use an extension tube or even close-up lens.
I wish I knew what that symbol between Tokina and 80-200mm meant.
Any ideas?
Removing the Canon FD mount is a little tricky. There is one black screw visible here. I understand two more are visible when the breech-mount ring is in the closed position. Since you can’t close the ring until a pin is depressed by the camera mount pressing against it, it would take a little probing to trigger the shut down. Note the rear lens group stays where you see it. It is a clever design that keeps the zoom’s innards from getting dusty.
This lens came with (from upper right) a lens cap cord strap, a skylight filter, the lens cap and finally a rubber lens hood. The lens hood and the filter were stuck together. I held them under flowing hot water until they parted. I wanted to get them apart because I thought they were stacked in the wrong order.
I am pretty sure the filter should always be closest to the lens. On the other hand it is possible the hood might vignette the frame when the zoom is at the 70 mm end of the zoom. The extra thickness of the filter might just push the hood too far forward.
Incidentally I know that Pentax made a curved filter because they thought it was important to keep the filter’s parallel surfaces perpendicular to the lenses curved front surface. I was almost shocked recently when I removed a zoom’s skylight filter and the contrast of the image through the viewfinder jumped considerably. Try with filter and without filter and see if your results are better without.
