Rollei 90mm & 150mm Apo Makro lenses

[billy_jim]

Does anyone know how large the image circles are for these lenses

when focused at infinity and at 1:1, and at what f-stop?

Dear Billy:

The 90 mm at infinity is 138 mm, the 150 mm is reported to be larger and course both at 1:1 much greater. The f-stop is unspecified. This is one of those things you should be able to get from Rollei in N. J. but probably won't. I have both lenses, they are superb.

Ed, thanks for your response.

As an assistant I've used all the medium format brands extensively,

but I now find the Rollei system the most intriguing, especially if it

allows the following:

 

1) use the 90mm & 150mm apo makro lenses for 6x6 beauty, macro &

portrait photos of course : ) , 2) mount the 90mm & 150mm apo makro

lenses to the Rollei lens adapter system 6000 [controlled by the

LensControl S] for 4x5 use, and 3) mount my APO view camera lenses

onto the Rollei Electronic Shutter size 0 & size 1 [controlled by the

LensControl S] for 8x10 use

 

Having used Sinar's auto-aperture [mechanical] and digital shutters

for the past twenty years I find Rollei's offerings very tempting if

their claims of repeatable 1/12 f-stop accuracy are true.
