In short, for sharpness! I'm not steady enough to get a sharp shot with this gear and conditions while keeping ISO low. It's a big heavy body with a big heavy lens on it.
I was shooting a 300mm lens and on the mono shot it had a 1.4x TC with it for an effective 420mm. If I followed the old reciprocal rule for handheld shooting, I'd need a shutter speed of at least 1/300 or 1/420. I like to shoot this old camera at ISO 100 whenever possible and pretty much never over 400 or the noise is just too much.
In addition, I just like a tripod for landscape or architecture photos. It makes me think about composition more and I get better photos.
