Description

MS-Optics Apoqualia-G 28mm f2 Ultra Thin Version II

The original Apoqualia was a huge hit. And sold out really fast. So Miyazaki has decided to put put a new version of this great lens. Still the same great optics, but a new streamlined barrel and helicoid. This one is sure to be a huge hit too. Best be quick.
Lens details:

APOQUALIA 28mm F2 Full MC

Due to the retro-focus designs and aspherical elements that have become the norm in recent years, 28mm F2 lenses now have very high optical performance. However, such lenses are bigger which makes them poor for doing footwork. I am always aiming for something unique so I continued my research on a compact gauss formula lens and finally came up with an extremely compact lens only 50mm in diameter, 9.8mm long, and weighing just 70 grams that delivers my kind of character and gentleness of performance.

Astigmatism is fully corrected (although field curvature of about 0.3m/m remains) and a beautiful circular image with beautiful bokeh is obtained at the point of focus. Chromatic aberration is minimal and on par with what you would expect for an APO lens, and curvature is minimal at about 1/5 to 1/8 that of a retro-focus lens. Sagittal coma, which is a weakness of the gauss design, cannot be avoided, and coma flare increases from the middle of the image towards the corners at f2 to f2.5. However, the center 20mm circle of the image has good sharpness and contrast to emphasize a subject placed at the center. The focus shift from the center out to the 70 degrees position is about 0.2m/m, which is minimal but you might notice it if shooting flat surfaces wide open to f2.8.

To use this lens skillfully, it is important to combine its strengths and weaknesses. Performance is very good when the lens is stopped down to f4 and beyond, making it a good all-rounder lens. f2 to f2.5 is the aperture range in which the character of this lens appears, and the high contrast in the center 20mm circle and beautiful flare wide open can be utilized to good effect.

Please note this lens does not work with Bessa cameras.
