I'm selling my 21mm Super Angulon f/4 M mount in favor of something a little more "practical". While in Cuba earlier this year, I found myself using the Zeiss 28mm f/2.8 on my Contax G2 quite a bit but for my next few trips, I'll bring only a couple of M bodies (M7 & Typ 246). I really love the results that I got out of my Zeiss and am wondering if I should go with another Zeiss (25mm f/2.8 or 28mm f/2.8) OR a new-ish 28mm Elmarit ASPH. So my two questions are "is the Elmarit ASPH quality worth more than double the price of a used Zeiss 25mm or 28mm?" and "In order to keep my work consistent, should I just stick with the Zeiss 28mm f/2.8 for the way it renders colors?" Examples of my work in Cuba with the 28mm f/2.8 on the Contax G2 below. Both photos with Portra 400.
