A short telephoto lens is often seen as a portrait lens. Certainly, the CV 75/2.5 fits the part. For someone looking specifically for a portrait lens, there is a another good Voigtländer alternative: the new 75/1.8 Heliar. While the CV 75/2.5 is sharp across the aperture range, the CV 75/1.8 is said to give a softer look wide open. A razor-sharp portrait is seldom appreciated. You don't want your portraits to look like this:

CV 75/2.5 as a travel lens
Few of us enjoy a large and heavy kit for travel. The CV 75/2.5 is only 64.5 mm long and weighs merely 230 g. The newer CV 75/1.8 is hardly that much bigger at 73.8 mm although at 427 g it weighs almost twice as much as the tiny 75/2.5. For travel any reduction in bulk or weight is however warmly welcomed.
In addition to portraits, a telephoto lens is useful for excluding unwanted distractions from your photographs, photographing details, and compressing landscapes and distant views. Below you can find examples of all three. It would have been difficult to avoid the crowds of tourist in the first photograph with a wider lens. Much the same is achieved with a telephoto lens in the third photo. More importantly, the scale of the buildings is better perceived due to the compression effect. I have included 100% crops of both close and more distant details to give some idea of the lens sharpness (see the links). I can say this is one sharp lens even wide open.

Perhaps the only minor gripe I have about this lens is its close focus distance, which is unfortunately limited to 1 m. A 0.7-m limit would make it much more useful, especially for travel when you wish to get by with as little gear as possible. The CV 75/1.8 focuses down to 0.9 m, so it is only slightly better in this respect.
