Kolari Vision thin-stack mod on a7II — Leica 24/2.8 Elmarit-M

July 25, 2015 JimK 2 Comments

This is part 7 in a series of posts on a prototype of the Kolari Vision thin-stack sensor modification for the Sony a7II. The series starts here.

The Leica 24mm f/2.8 Super Elmarit-M ASPH is a fair-at-best performer on the Sony a7x cameras. How is it on the Kolari-modified a7II?

The scene, at f/2.8, with both a stock and a Kolari-modified a7II:

Same color shift we saw in the earlier pictures.

In the lower left corner, at all whole apertures, enlarged 3:1, processed in Lightroom with daylight white balance and otherwise default settings:

 

Standard f/2
Standard f/2.8
Kolari f/2
Kolari f/2.8

The Kolari is better, but neither is acceptable.

Standard f/2.8
Standard f/4
Kolari f/2.8
Kolari f/4

Kolari is better; both are soft.

Standard f/4
Standard f/5.6
Kolari f/4
Kolari f/5.6

The Kolari is now pretty good. The standard stack is still soft.

Standard f/5.6
Standard f/8
Kolari f/5.6
Kolari f/8

Both are pretty good, with the Kolari getting the nod.

Standard f/8
Standard f/11
Kolari f/8
Kolari f/11

Both are good. Kolari is better.

Standard f/11
Standard f/16
Kolari f/11
Kolari f/16

Diffraction is setting in. Kolari is slightly better, probably because of the lack of an AA filter.

    Leica doesn’t have a “24mm f/2 Super Elmarit-M ASPH”. Do you mean 28mm f/2 Summicron-M ASPH?

      It’s an f/2.8 lens. Sorry for the error. Fixed now.
