Dear Charles,

I have had a lot of fun over the years with a 500 mm Cat Lens which has a 
T-mount.
This lens has a fixed f stop of f8 so the only ways I can vary the exposure are 
by changing
the speed or adding filters to the front or the back or by using a doubler.
Most of the time I just use the old reciprocity rule and set the shutter speed 
to 1/500.  At other
times I use a flash and make a "guesstimate" based on the guide number of the 
flash and whether
I'm using a fresnel lens to project the flash.

I put such a 1000 mm picture on the hummingbird section of my web site.

When I'm using an OM2S I just let the camera determine the exposure and it 
always comes out
bang on polarizer or not.

I've seen the "Cat" lenses for sale on the used market for around a hundred 
dollars and the new
catalog price of a Ritz Quantaray (the one I use) for $125 !  Where else can 
you get such awesome
focal length so cheaply ?  It's a great addition to any photographer's arsenal 
of lenses !

Many of my favorite pictures were taken with a "Cat" (catadioptric aka mirror, 
reflex) lens.
