How to mount a lens on SL66 with adapter

How to mount a lens on SL66 with adapter

From Lens adapter for Rolleiflex SL66

what lens adapter can do?
With a lens adapter, you can mount variety of lenses on SL66, barrel lenses from process cameras, enlargers, or vintage cameras, and large format camera lenses with #0 or #1 shutters. You can drilled any size of hole on it for your own usage, as it no bigger than 57mm in diameter. Usually a hole drilled for #0 shutter will be 35mm in diameter, for #1 shutter, 42mm is enough, and for enlarger lenses, there are standards, some lenses are for 39mm lens thread, some for 49mm; I own a process lens (Konica Hexanon GRII 150mm f/9), it takes 46mm in diameter.  Best you asked for a pre-drilled lens adapter in the hole size you specify, for it is not so easy to find a mechist to do it for you, and for an adapter so delicated, it is even harder not to harm its surface during processing.

what lenses I can mount on?
Lenses you mount will at least have 110mm in focal length, or you will not be able to focus to infinity. I have 1 lens with 105mm in focal length, still can use them if focus within 2m range.
And limited by SL66 built-in focus bellows length, you need extension tube added for lenses with 165mm or more focal length.

How to mount a lens on it?
Here we take a lens with #0 shutter for example (Schneider-Kreuznach Apo-Symma 1:5.6/150).

First thing you should do, is to mount the blank adapter onto camera, and then mark the upper right place with a marker, sticker, liquid paper or anything you can recognize. I use a little bit of presick clay, remove it easily later. Remove the adapter, now you are  ready to mount the lens.

There are two ways to mount lens on it.

1. Remove the rear element of the lens, remove the tiny screw on the back of shutter, with a tiny screwdriver. that tiny screw is used as a fixture, preventing shutter rotating while operating (keep it in a secure place, don't lost it!). mount the shutter onto the adapter, rotate to adajust the upper right is in the right place, tightly screw the shutter with retaining ring with wrench, make sure shutter would not rotate on the adapter, then replace the lens rear element.

Three kinds of wrench I used.

2.Remove the rear element of the lens, according the position of the tiny screw on the back of shutter, file an indentation on the hole of adapter, till you can fit the shutter onto adapter. Tightly screw the shutter with retaining ring with wrench, make sure shutter would not rotate on the adapter, then replace the lens rear element.

Tightly screw the shutter with retaining ring with wrench


In my personal opinion, I prefer the first way, since it is much easier compare to the second way, if you tightly screw the retaining ring, there is no need to worry about shutter rotation during operation. Just remember DO NOT lost that tiny screw!!

Take off the rear element of this lens, and with a 80mm extension tube, it became a tele lens

180mm lens need 40mm extension tube to focus to infinity.

with 40+80mm extension tube, 315mm lens can focus to infinity without
using bellows, it means you can focus to very closed distance also.

315mm lens looks like a gun!
