I recommend the Elmarit. The build quality and ergonomics are great (very close to earlier generation 35/2 lenses) and performance second to none. I was lucky enough to swap a Type IV Elmarit for this newer model two or three years ago.
The Elmarit is faster, smaller and lighter than my 24/3.8 Elmar, but the Elmar is unbeatable in CA control, lack of distortion and corner sharpness. However, the compactness and ease of framing (without external viewfinder) is a great!
