Hi Jerry
Appreciate this v. detailed info.  The one thing  I miss on the rollei (wrt
50mm SLR) is not being able to get closer than 1m for some subjects. Up to
now I have just cropped 1m shots

.....which certainly wont hold up to high such high mag.

Hi Chat:

I have used rolleinars for quite a while and i have found that rolleinar 1
and
rolleinar 2 are the most useful. Number 1 is good for general picture
taking
when you want the subject a little closer. Image degradation is really
minimal
at the center of the image though edges suffer. Number 3 rolleinars are
fun to
play with but i have never been able to use them successfully. At the
center,
image is pretty good, esp. if you close down to f/16, but depth of field
is
still really really shallow. it is hard to take a picture of anything
larger
than a flat surface the size of your fist and keep it all in focus.

I like rolleinar 2 the best because it does get me closer to what I want
to
photograph without the problems of rolleinar 3. In any event, close down
to
f/16 or f/22 and carefully center your image because you have to figure
that
each rolleinar grade cuts down on the useful part of the negative. A
rolleinar
1 will give you about half a negative that is good (without edge blurring)
, a
rolleinar 2 gives about a third of a negative and rolleinar 3 gives much
less
than that. Rather than seeing the different powers in terms of different
magnifications---because they will take you to different degrees of
closeness--
I think of maginification powers in terms of how much of the negative I
want to
use. If I need half the negative, use #1, like for a small bunch of
flowers. If
i wanted to photograph something much smaller, such as one flower a
doorknob,
etc., I would go for a three since I am going to be using only a small
part of
the negative. This may explain why I like #2 best, because it gives the
most
leeway in terms of size of subject, useful part of negative etc. --  When
I
took picture of the pumpkin stem with a number 3 lens, only a very very
small
part of the stem was in focus with most of it a blur.

Some people argue that it is better to use the same close up lens on the
viewfinder and then shift it to the taking lens and raise the camera on a
parajuster. Technically, I am sure this will give a more accurate picture
than
using the two lens rollei set up. But, at first, I would certainly use the
two
lens set up. I have been happy doing it both ways.

I think the biggest help for using a close-up lens on a rollei is focusing
through a prism. The prism gives a larger image than the viewfinder but,
more
important, it permits far more accurate fine detail focusing.

I have never tried to take a close up of an insect, etc etc or any of the
other
amazing things one sees in magazines. These are all possible with
intechangable
lens cameras.  But you can not do it with a rollei and a rolleinar. Modest
closeups are fine but nothing dramatic. Since I am a modest and
non-dramatic
photographer, I have been happy as hell.

I use Tmax 400 because i am one of the few who really likes the sharp
grain.
But if you have trouble with enlarging the image as much as you want, use
Tmax
100 because it is quite an amazing film that can record a great deal of
detail.

Best wishes, Jerry
