I have the opportunity to get a G-Claron 9/240 at a very reasonable price. I
was thinking of using it for enlarging. Bad idea? Currently I use a Componon
150mm and it's adequate, but not stunning.

It should be a good lens for enlarging. But will it fit your enlarger?

1.) Be sure the rear element is small enough to go into the enlarger.
2.) Be sure your bellows are long enough to focus at the reproduction
ratios you will be employing.
3.) Be sure your enlarger head will go up far enough to get the image
sizes you want.

Ach. You are right. I don't have enough bellows draw.

 Get it for the camera. It'll cover 8x10 with movements. Screws straight
into a #1 shutter.

    On the enlarger do you have enough bellows? It's also a stop slower
then your current lens.

    If the price is right. Buy it. Try it. If you don't like it then you
can flip it easy enough.

Good idea.  It is in a shutter that use two cable releases: one for focusing
and the other to expose. No cocking lever. Very clean. $150. I might put it
on the 8x10 to help sell it.

    $150 is a steel. I have this lens and it's very good. I
haven't used it for enlarging though. Got it on my 4X5 at first and
now it's on my 5X7 Linhof.

Look for the 150mm G-Claron, instead.

You will need long arms for focusing.

I assume you're enlarging 4x5 film if you're using a 150mm Componon. If
you went to a 240mm lens the maximum size of your enlargements would
significantly decrease. On my Beseler 45 I have a max of about 37
inches between the negative and baseboard. I could get a magnification
of 37/6(=150mm)-1=5.16x enlargement with a 6" lens. With a 240mnm lens
I could only get 37/9.5(=240mm)-1=2.9x enlargement, or a bit more than
half as much enlargement as with the 150mm lens. You can always go to
an enlarger table with adjustable baseboard height to make up for the
difference, but I thought you should know.
