Verdict

The Pentax SMC DA 35mm f/2.4 AL may be a low-cost prime lens but it is actually a more than decent performer. This isn't overly surprising actually because moderately fast prime lenses tend to be a very safe bet. The lens is very sharp across the frame in the relevant aperture range with a peak around f/4. The low CAs contribute to the very high quality perception as well. The lens produces only a slight degree of barrel distortion. Vignetting is nothing to worry about except in very critical situation when using the max. aperture setting. However, the bokeh is a little nervous with respect to out-of-focus highlights as well as the quality of the foreground blur. Bokeh fringing can also be an issue at f/2.4.

So optically the lens plays close to the big league. However, the cost cutting measurements are somewhat more obvious in the mechanical implementation. The build quality is okay for an all-plastic construction but it's nothing to rave about either. On the positive side, this approach results in an ultra-light weight package of just 124g. The lens features an old-style AF driven by the camera's AF drive screw. Speed-wise this has no negative effect - the Pentax K5 focuses very fast with this lens - but AF operations are very noticeable acoustically.

The Pentax DA 35mm f/2.4 AL may not be the most sexy offer around but it's certainly a very interesting new option for photographers on a budget or for those seeking a low-weight "standard" prime lens.
