Side by side with Minolta AF 85mm F 1.4 (D)


Can you tell us more about these lenses, please?

Why does the 40-80mm have that unusual build?

This was Minolta's way to make a wide aperture zoom at the time. It was actually Minolta's first cross standard zoom going from somewhat wide to short tele. From my count, there would be very few made, probably around 800 units of the MD version so i can consider it as rare.
You can read more about it here:

And how do the two 85s differ?


The 85mm F 1.4 G (D) Limited was made in only 700 copies and was sold exclusively in the Japanese market ( along the Minolta A7 Limited ?) around 2001-2002. It was designed for better bokeh taking into account some lens defects that can be mastered to help achieve that effect.

Quote from some posts i found a long time ago about this lens:
" The 'new" AF85mm 1.4 limited edition is supposed to be available from
end of May. However, due to some reasons, they delay it to June/July
this year. (from their Japanese web page)
Originally, Minolta had two designs of 85mm F1.4 inhouse. The current
AF85mm 1.4G is one of the two. At that time, they chose this current
design over another because of heavier weight & size. Also it turns
out to be an outstanding lens among other OEMs.
But that abandoned design is performing better when the lens is wide
open!
Now, they come back with the abandoned design but at a quantity of
700 only. That's why it is called "Limited edition"
The optical formula is the same - equal numbers of lens elements &
groups. However, the front element(s) is/are enlarged to achieve
under-compensation for spherical aberrations & minimized sagittal
flare & flare on film plan region. That's why it is 215 grams heavier
over the "old" design (& bigger too).
By doing this, the "new" lens renders higher contrast, vivid colour
for in-focus area, while out-of-focus area much softer & smooth
compared with the "old" design. (also partly due to nearly complete
elimination of halo.) It can be taken as a continuous pursuit of
excellent out-of-focus rendering after 135STF.
Such change allows very high resolution to be achieved at the centre
at wide open aperture. Famous examples of under-compensation: include
Planar T*100/2, Sonnar T*90/2.8, & early Cannon FD85/1.2."

This is a heavy piece of glass but provides the smoothest out of focus transitions i have ever experienced.

Interesting! Thank you for the information, Michel. Like 1 small
I become entirely irrational when thinking about big, beautiful, fast prime lenses!

Guess my rare russian space lens ZIKAR-1 f1.2/100mm fits here...


More details!
Please? Wink

What was this lens originally used for?
Is it useful for general photography or just science?


It often simply helps to use the SEARCH FUNCTION we have here, as we had a discussion about it here after I found it Wink

Smile Yes, thanks for the reply. I'll try to remember to search before I ask.
