Angenieux makes fantastic lenses. I was lucky to obtain a nearly mint sample of the 35-70/2.5-3.3, the only wide zoom Angenieux made in manual focus in a Nikon F mouth. From what I understood the zoom was developed according to the Leitz specs but Leitz decided to join efforts with Minolta. Angenieux earlier made the 45-90/2.8 for Leitz. The 35-70/2.5 was made in relative small numbers because of the steep price and produced between 1983 and 1987.
The strongest points are the colours, bokeh, transition between light and dark, contrast, close focus distance of 45cm, the sharpness wide open and a real versatile hyperfocal Zoom. Some weak points as well, as any lens, flare against the sun, some vignetting at 35mm and barrel distortion, but that's also caused by using it beyond the specs of close focus of 1m. It allows to focus at 45cm.
Some examples I posted here before:
