According to my friend Leonard Foo of MIR...
"You can called a Reflex Lens a poor man's ED lens.
In a reflex lens, light path is 'folded' by the mirror surfaces.
This permits the design of lens type permitting a significant reduction in size and weight as compared to conventional lenses of equivalent focal length.
Since the light path is folded, another benefit is the virtual elimination of chromatic aberration, this provides images taken with mirror lens with superior sharpness and contrast!"
Tokina has launched a 300mm F/6.3 Compact Reflex Mirror Lens for Micro 4/3rds Mount. The lens gives an effective 600mm FOV on the mirrorless camera.
The 300 grams, 66x66mm (length/diameter) Tokina is a manual-focus lens with a fixed f6.3 aperture. The lens takes 55mm filters, focuses down to 0.8m and offers a maximum reproduction ratio of 1:2.
One of the characteristics of mirror lens is the donuts shaped bokeh. Which some find distracting, others might like the way out of focus area is rendered in such a way making it more distinct when compared to non-mirror lens.
So how good is this NZ$ 700.00 (I am guessing) catadioptric lens?
A Japanese site, DSLR Check, has published a resolution comparison test using the new mirrored lens on different cameras.... take a look below:
Look pretty good to me :) I want one!!
Famous Last Word...
When I was in my younger day, when I was working as a news photographer in Kuala Lumpur; I used a Nikon 500mm f8 Mirror lens on a Nikon F2 film camera to stalk a bird, NOT that kind of bird you are thinking of! Duh! ;)
This is the news clipping of that stalk...
And this is the picture! Shot on Kodak Tri-X B&W film.
I love the doughnut bokeh! Do you?
