Not for the faint-hearted, but wonderful when mastered.

Summary: The 85mm market is crowded with Canon. Canon has their 85mm f/1.8 (excellent quality and value!), their uber-expensive f/1.2, as well as Sigma f/1.4 models from Sigma, Samyang and Zeiss. Between the Canon's is the Sigma with a fair price and the Samyang appeals to the budget market due to its manual aperture and focus ring (no electronics). The Zeiss sits between the Canon 1.2 and the Sigma in terms of price, which is weird because it is manual focus only.
Summary: I love being able to use this superb Carl Zeiss short telephoto lens on my Canon EOS digital bodies. When used on the cropped sensor of Canon's 10D, it works great as a portrait lens. With the maximum aperture of f/1.4, I can handhold in low light situations and the "bokeh" is beautiful. I use the type of lens mount adapter with a "focus assist" chip installed on it (which I purchased on eBay) to help with the manual focus lens.
