A moderate wide angle to moderate telephoto zoom lens with above average optical performance. This lens is more compact than the earlier model 22A and features a completely new optical design which retains a floating front focus group as used in the earlier model 22A optical design. This lens trades off the earlier model's CF macro ability at 135mm in favor of a significantly more compact overall design. Maximum macro magnification is achieved at 35mm by using the built-in macro button and turning the macro helicoid ring, an operation which is similar in function to Tamron's SP 28-135. Although the macro function is less convenient compared to the earlier model 22A design, this lens is more compact and uses smaller filters.
