That is certainly the case with virtually every type of closeup equipment other than a macro lens. Extension tubes, Achromats, Bellows, etc will all restrict your range of focus. But, when searching the bushes for bugs or interesting flower details I won't be using the infinity end of the range. True, a proper macro lens will give you better framing options because of the large range of focus but, an achromat on a zoom offers the same flexibility in the near ranges.
While I really love my Micro-Nikkors (55, 60 and 105mm) for a lot of uses, walking out in the field with my little Nikon V1, 30-110mm with an old Leitz ELPRO in my pocket lets me get good images of interesting finds. Like this.
You need to be careful in choosing an achromat that the lens is not too powerful for your needs and is suitable for the lens you will be mounting it on.
